The Complete IB Extended Essay Guide: Examples, Topics, and Ideas

International Baccalaureate (IB)

IB students around the globe fear writing the Extended Essay, but it doesn't have to be a source of stress! In this article, I'll get you excited about writing your Extended Essay and provide you with the resources you need to get an A on it.

If you're reading this article, I'm going to assume you're an IB student getting ready to write your Extended Essay. If you're looking at this as a potential future IB student, I recommend reading our introductory IB articles first, including our guide to what the IB program is and our full coverage of the IB curriculum .

IB Extended Essay: Why Should You Trust My Advice?

I myself am a recipient of an IB Diploma, and I happened to receive an A on my IB Extended Essay. Don't believe me? The proof is in the IBO pudding:

If you're confused by what this report means, EE is short for Extended Essay , and English A1 is the subject that my Extended Essay topic coordinated with. In layman's terms, my IB Diploma was graded in May 2010, I wrote my Extended Essay in the English A1 category, and I received an A grade on it.

What Is the Extended Essay in the IB Diploma Programme?

The IB Extended Essay, or EE , is a mini-thesis you write under the supervision of an IB advisor (an IB teacher at your school), which counts toward your IB Diploma (learn more about the major IB Diploma requirements in our guide) . I will explain exactly how the EE affects your Diploma later in this article.

For the Extended Essay, you will choose a research question as a topic, conduct the research independently, then write an essay on your findings . The essay itself is a long one—although there's a cap of 4,000 words, most successful essays get very close to this limit.

Keep in mind that the IB requires this essay to be a "formal piece of academic writing," meaning you'll have to do outside research and cite additional sources.

The IB Extended Essay must include the following:

A title page
Contents page
Introduction
Body of the essay
References and bibliography

Additionally, your research topic must fall into one of the six approved DP categories , or IB subject groups, which are as follows:

Group 1: Studies in Language and Literature
Group 2: Language Acquisition
Group 3: Individuals and Societies
Group 4: Sciences
Group 5: Mathematics
Group 6: The Arts

Once you figure out your category and have identified a potential research topic, it's time to pick your advisor, who is normally an IB teacher at your school (though you can also find one online ). This person will help direct your research, and they'll conduct the reflection sessions you'll have to do as part of your Extended Essay.

As of 2018, the IB requires a "reflection process" as part of your EE supervision process. To fulfill this requirement, you have to meet at least three times with your supervisor in what the IB calls "reflection sessions." These meetings are not only mandatory but are also part of the formal assessment of the EE and your research methods.

According to the IB, the purpose of these meetings is to "provide an opportunity for students to reflect on their engagement with the research process." Basically, these meetings give your supervisor the opportunity to offer feedback, push you to think differently, and encourage you to evaluate your research process.

The final reflection session is called the viva voce, and it's a short 10- to 15-minute interview between you and your advisor. This happens at the very end of the EE process, and it's designed to help your advisor write their report, which factors into your EE grade.

Here are the topics covered in your viva voce :

A check on plagiarism and malpractice
Your reflection on your project's successes and difficulties
Your reflection on what you've learned during the EE process

Your completed Extended Essay, along with your supervisor's report, will then be sent to the IB to be graded. We'll cover the assessment criteria in just a moment.

We'll help you learn how to have those "lightbulb" moments...even on test day!

What Should You Write About in Your IB Extended Essay?

You can technically write about anything, so long as it falls within one of the approved categories listed above.

It's best to choose a topic that matches one of the IB courses , (such as Theatre, Film, Spanish, French, Math, Biology, etc.), which shouldn't be difficult because there are so many class subjects.

Here is a range of sample topics with the attached extended essay:

Biology: The Effect of Age and Gender on the Photoreceptor Cells in the Human Retina
Chemistry: How Does Reflux Time Affect the Yield and Purity of Ethyl Aminobenzoate (Benzocaine), and How Effective is Recrystallisation as a Purification Technique for This Compound?
English: An Exploration of Jane Austen's Use of the Outdoors in Emma
Geography: The Effect of Location on the Educational Attainment of Indigenous Secondary Students in Queensland, Australia
Math: Alhazen's Billiard Problem
Visual Arts: Can Luc Tuymans Be Classified as a Political Painter?

You can see from how varied the topics are that you have a lot of freedom when it comes to picking a topic . So how do you pick when the options are limitless?

How to Write a Stellar IB Extended Essay: 6 Essential Tips

Below are six key tips to keep in mind as you work on your Extended Essay for the IB DP. Follow these and you're sure to get an A!

#1: Write About Something You Enjoy

You can't expect to write a compelling essay if you're not a fan of the topic on which you're writing. For example, I just love British theatre and ended up writing my Extended Essay on a revolution in post-WWII British theatre. (Yes, I'm definitely a #TheatreNerd.)

I really encourage anyone who pursues an IB Diploma to take the Extended Essay seriously. I was fortunate enough to receive a full-tuition merit scholarship to USC's School of Dramatic Arts program. In my interview for the scholarship, I spoke passionately about my Extended Essay; thus, I genuinely think my Extended Essay helped me get my scholarship.

But how do you find a topic you're passionate about? Start by thinking about which classes you enjoy the most and why . Do you like math classes because you like to solve problems? Or do you enjoy English because you like to analyze literary texts?

Keep in mind that there's no right or wrong answer when it comes to choosing your Extended Essay topic. You're not more likely to get high marks because you're writing about science, just like you're not doomed to failure because you've chosen to tackle the social sciences. The quality of what you produce—not the field you choose to research within—will determine your grade.

Once you've figured out your category, you should brainstorm more specific topics by putting pen to paper . What was your favorite chapter you learned in that class? Was it astrophysics or mechanics? What did you like about that specific chapter? Is there something you want to learn more about? I recommend spending a few hours on this type of brainstorming.

One last note: if you're truly stumped on what to research, pick a topic that will help you in your future major or career . That way you can use your Extended Essay as a talking point in your college essays (and it will prepare you for your studies to come too!).

#2: Select a Topic That Is Neither Too Broad nor Too Narrow

There's a fine line between broad and narrow. You need to write about something specific, but not so specific that you can't write 4,000 words on it.

You can't write about WWII because that would be a book's worth of material. You also don't want to write about what type of soup prisoners of war received behind enemy lines, because you probably won’t be able to come up with 4,000 words of material about it. However, you could possibly write about how the conditions in German POW camps—and the rations provided—were directly affected by the Nazis' successes and failures on the front, including the use of captured factories and prison labor in Eastern Europe to increase production. WWII military history might be a little overdone, but you get my point.

If you're really stuck trying to pinpoint a not-too-broad-or-too-narrow topic, I suggest trying to brainstorm a topic that uses a comparison. Once you begin looking through the list of sample essays below, you'll notice that many use comparisons to formulate their main arguments.

I also used a comparison in my EE, contrasting Harold Pinter's Party Time with John Osborne's Look Back in Anger in order to show a transition in British theatre. Topics with comparisons of two to three plays, books, and so on tend to be the sweet spot. You can analyze each item and then compare them with one another after doing some in-depth analysis of each individually. The ways these items compare and contrast will end up forming the thesis of your essay!

When choosing a comparative topic, the key is that the comparison should be significant. I compared two plays to illustrate the transition in British theatre, but you could compare the ways different regional dialects affect people's job prospects or how different temperatures may or may not affect the mating patterns of lightning bugs. The point here is that comparisons not only help you limit your topic, but they also help you build your argument.

Comparisons are not the only way to get a grade-A EE, though. If after brainstorming, you pick a non-comparison-based topic and are still unsure whether your topic is too broad or narrow, spend about 30 minutes doing some basic research and see how much material is out there.

If there are more than 1,000 books, articles, or documentaries out there on that exact topic, it may be too broad. But if there are only two books that have any connection to your topic, it may be too narrow. If you're still unsure, ask your advisor—it's what they're there for! Speaking of advisors...

Don't get stuck with a narrow topic!

#3: Choose an Advisor Who Is Familiar With Your Topic

If you're not certain of who you would like to be your advisor, create a list of your top three choices. Next, write down the pros and cons of each possibility (I know this sounds tedious, but it really helps!).

For example, Mr. Green is my favorite teacher and we get along really well, but he teaches English. For my EE, I want to conduct an experiment that compares the efficiency of American electric cars with foreign electric cars.

I had Ms. White a year ago. She teaches physics and enjoyed having me in her class. Unlike Mr. Green, Ms. White could help me design my experiment.

Based on my topic and what I need from my advisor, Ms. White would be a better fit for me than would Mr. Green (even though I like him a lot).

The moral of my story is this: do not just ask your favorite teacher to be your advisor . They might be a hindrance to you if they teach another subject. For example, I would not recommend asking your biology teacher to guide you in writing an English literature-based EE.

There can, of course, be exceptions to this rule. If you have a teacher who's passionate and knowledgeable about your topic (as my English teacher was about my theatre topic), you could ask that instructor. Consider all your options before you do this. There was no theatre teacher at my high school, so I couldn't find a theatre-specific advisor, but I chose the next best thing.

Before you approach a teacher to serve as your advisor, check with your high school to see what requirements they have for this process. Some IB high schools require your IB Extended Essay advisor to sign an Agreement Form , for instance.

Make sure that you ask your IB coordinator whether there is any required paperwork to fill out. If your school needs a specific form signed, bring it with you when you ask your teacher to be your EE advisor.

#4: Pick an Advisor Who Will Push You to Be Your Best

Some teachers might just take on students because they have to and aren't very passionate about reading drafts, only giving you minimal feedback. Choose a teacher who will take the time to read several drafts of your essay and give you extensive notes. I would not have gotten my A without being pushed to make my Extended Essay draft better.

Ask a teacher that you have experience with through class or an extracurricular activity. Do not ask a teacher that you have absolutely no connection to. If a teacher already knows you, that means they already know your strengths and weaknesses, so they know what to look for, where you need to improve, and how to encourage your best work.

Also, don't forget that your supervisor's assessment is part of your overall EE score . If you're meeting with someone who pushes you to do better—and you actually take their advice—they'll have more impressive things to say about you than a supervisor who doesn't know you well and isn't heavily involved in your research process.

Be aware that the IB only allows advisors to make suggestions and give constructive criticism. Your teacher cannot actually help you write your EE. The IB recommends that the supervisor spends approximately two to three hours in total with the candidate discussing the EE.

#5: Make Sure Your Essay Has a Clear Structure and Flow

The IB likes structure. Your EE needs a clear introduction (which should be one to two double-spaced pages), research question/focus (i.e., what you're investigating), a body, and a conclusion (about one double-spaced page). An essay with unclear organization will be graded poorly.

The body of your EE should make up the bulk of the essay. It should be about eight to 18 pages long (again, depending on your topic). Your body can be split into multiple parts. For example, if you were doing a comparison, you might have one third of your body as Novel A Analysis, another third as Novel B Analysis, and the final third as your comparison of Novels A and B.

If you're conducting an experiment or analyzing data, such as in this EE , your EE body should have a clear structure that aligns with the scientific method ; you should state the research question, discuss your method, present the data, analyze the data, explain any uncertainties, and draw a conclusion and/or evaluate the success of the experiment.

#6: Start Writing Sooner Rather Than Later!

You will not be able to crank out a 4,000-word essay in just a week and get an A on it. You'll be reading many, many articles (and, depending on your topic, possibly books and plays as well!). As such, it's imperative that you start your research as soon as possible.

Each school has a slightly different deadline for the Extended Essay. Some schools want them as soon as November of your senior year; others will take them as late as February. Your school will tell you what your deadline is. If they haven't mentioned it by February of your junior year, ask your IB coordinator about it.

Some high schools will provide you with a timeline of when you need to come up with a topic, when you need to meet with your advisor, and when certain drafts are due. Not all schools do this. Ask your IB coordinator if you are unsure whether you are on a specific timeline.

Below is my recommended EE timeline. While it's earlier than most schools, it'll save you a ton of heartache (trust me, I remember how hard this process was!):

January/February of Junior Year: Come up with your final research topic (or at least your top three options).
February of Junior Year: Approach a teacher about being your EE advisor. If they decline, keep asking others until you find one. See my notes above on how to pick an EE advisor.
April/May of Junior Year: Submit an outline of your EE and a bibliography of potential research sources (I recommend at least seven to 10) to your EE advisor. Meet with your EE advisor to discuss your outline.
Summer Between Junior and Senior Year: Complete your first full draft over the summer between your junior and senior year. I know, I know—no one wants to work during the summer, but trust me—this will save you so much stress come fall when you are busy with college applications and other internal assessments for your IB classes. You will want to have this first full draft done because you will want to complete a couple of draft cycles as you likely won't be able to get everything you want to say into 4,000 articulate words on the first attempt. Try to get this first draft into the best possible shape so you don't have to work on too many revisions during the school year on top of your homework, college applications, and extracurriculars.
August/September of Senior Year: Turn in your first draft of your EE to your advisor and receive feedback. Work on incorporating their feedback into your essay. If they have a lot of suggestions for improvement, ask if they will read one more draft before the final draft.
September/October of Senior Year: Submit the second draft of your EE to your advisor (if necessary) and look at their feedback. Work on creating the best possible final draft.
November-February of Senior Year: Schedule your viva voce. Submit two copies of your final draft to your school to be sent off to the IB. You likely will not get your grade until after you graduate.

Remember that in the middle of these milestones, you'll need to schedule two other reflection sessions with your advisor . (Your teachers will actually take notes on these sessions on a form like this one , which then gets submitted to the IB.)

I recommend doing them when you get feedback on your drafts, but these meetings will ultimately be up to your supervisor. Just don't forget to do them!

The early bird DOES get the worm!

How Is the IB Extended Essay Graded?

Extended Essays are graded by examiners appointed by the IB on a scale of 0 to 34 . You'll be graded on five criteria, each with its own set of points. You can learn more about how EE scoring works by reading the IB guide to extended essays .

Criterion A: Focus and Method (6 points maximum)
Criterion B: Knowledge and Understanding (6 points maximum)
Criterion C: Critical Thinking (12 points maximum)
Criterion D: Presentation (4 points maximum)
Criterion E: Engagement (6 points maximum)

How well you do on each of these criteria will determine the final letter grade you get for your EE. You must earn at least a D to be eligible to receive your IB Diploma.

Although each criterion has a point value, the IB explicitly states that graders are not converting point totals into grades; instead, they're using qualitative grade descriptors to determine the final grade of your Extended Essay . Grade descriptors are on pages 102-103 of this document .

Here's a rough estimate of how these different point values translate to letter grades based on previous scoring methods for the EE. This is just an estimate —you should read and understand the grade descriptors so you know exactly what the scorers are looking for.


30-34	Excellent: A
25-29	Good: B
17-24	Satisfactory: C
9-16	Mediocre: D
0-8	Elementary: E

Here is the breakdown of EE scores (from the May 2021 bulletin):


A	10.1%
B	24.4%
C	40.8%
D	22.5%
E	1.4%
N (No Grade Awarded)	0.7%

How Does the Extended Essay Grade Affect Your IB Diploma?

The Extended Essay grade is combined with your TOK (Theory of Knowledge) grade to determine how many points you get toward your IB Diploma.

To learn about Theory of Knowledge or how many points you need to receive an IB Diploma, read our complete guide to the IB program and our guide to the IB Diploma requirements .

This diagram shows how the two scores are combined to determine how many points you receive for your IB diploma (3 being the most, 0 being the least). In order to get your IB Diploma, you have to earn 24 points across both categories (the TOK and EE). The highest score anyone can earn is 45 points.

Let's say you get an A on your EE and a B on TOK. You will get 3 points toward your Diploma. As of 2014, a student who scores an E on either the extended essay or TOK essay will not be eligible to receive an IB Diploma .

Prior to the class of 2010, a Diploma candidate could receive a failing grade in either the Extended Essay or Theory of Knowledge and still be awarded a Diploma, but this is no longer true.

Figuring out how you're assessed can be a little tricky. Luckily, the IB breaks everything down here in this document . (The assessment information begins on page 219.)

IB CHEMISTRY: INTERNAL ASSESSMENT & EXTENDED ESSAY II

IB IA and EE

Independent and Dependent Variables – What to consider

In every IA or EE, the decision on which variable to manipulate and which variable that the manipulated variable affects is important. Typically, it is advisable to have only ONE dependent variable for IA and at least TWO for EE. The key reason for this difference is the amount of time that one spends in the laboratory – 10 hours for IA and 40 hours for EE. The big difference in the amount of time spent in the laboratory means two things

The independent and dependent variables for IA should be easily measurable.
The independent and dependent variables for EE can more complicated and indirect in measurement, but the method of measurement must be verified.

Independent Variable

There are principally two types of independent variables

Type of reagent such as type of acid/base, catalyst/inhibitor etc
Reaction condition such as temperature, pH, concentration, light intensity, light wavelength etc.

There are students who used other types of independent variables, such as

Brands of household product, beverage, food etc
Types of food and beverage

Some examples are

Brands of detergents
Types of tea, eg.English breakfast tea, Ceylon tea etc.
Types of coffee eg. Arabica coffee, Blue Mountain coffee etc

While exploring the difference in types of food and beverage or brands of products may seem like a possible independent variable, we highly discourage it. The reason is that it will be very challenging to explain the results of the experiment using concepts in Chemistry, thus the “discussion” section of the report will not be substantial.

Some independent variables are harder to control, such as the wavelength or intensity of light. Such independent variables manipulation requires the setup of special units that disallow ambient light interference. We have helped students design and built such setups for experiments, and are contactable through email or phone for a discussion.

Dependent variable

In deciding the dependent variable, one has to consider the following

Is the independent measurable using existing equipment or using methods doable in the school laboratory?

For example,

– Temperature using thermometer

– Concentration of coloured liquid substances using UV-VIS spectrophotometer or colorimeter

– Concentration of certain colourless organic liquid substances using uv-vis spectrometer

Some students might vary the type of chemicals used in the experimental study. In this case, the student should check if the chemical(s) is available in the laboratory or permissible (non-hazardous or carcinogenic) in the laboratory. In some cases, the chemical might not be available in the school laboratory and the cost of the chemical might be beyond the budget allocated to each student. In such a scenario, it might be possible that the student has to pay for the chemical required.

General

CHEMISTRY EXTENDED ESSAY

These subject guidelines should be read in conjunction with the IB extended essay general guidelines.

Introduction

An extended essay in chemistry provides a candidate with an opportunity to investigate personally a particular aspect of the materials of our environment. Such extended essays must be characterized by a particular chemical emphasis within a more general set of scientific criteria.

Choice of Topic

It is important that the extended essay has a clear chemical emphasis and is not more closely related to another subject. Chemistry is the science that deals with the composition, characterization, and transformation of substances. A chemistry extended essay should therefore incorporate chemical principles and theory, and emphasize the essential nature of chemistry, relating to the study of matter and of the changes it undergoes. Although similar criteria apply to all extended essays in the experimental sciences, for an extended essay submitted in chemistry the topic chosen must allow an approach which distinctly involves chemistry. Where a topic might be approached from different viewpoints, the treatment of the material must be approached from a chemical perspective.

An extended essay in an interdisciplinary area such as biochemistry will, if registered as a chemistry extended essay, be judged on its chemical content, not its biological content. The scope of the topic and the research associated with it should enable all the criteria, particularly the subject specific criteria, to be addressed. A good topic is one where the single research question is sharply focused and is susceptible to effective treatment within the word limit. Perhaps the most important factor is the depth of treatment that can be given to the topic by the candidate.

Some topics may be unsuitable for investigation because of safety issues. For example, experiments involving toxic or dangerous chemicals, carcinogenic substances or radioactive materials should be avoided unless adequate safety apparatus and qualified supervision is available.

Other topics may be unsuitable because the outcome is already well known and documented in standard text books and the candidate may not be able to show any personal input. An example might be a study of the reactions of the alkali metals with water as this is already covered by the syllabus. However some care does need to be exercised in deciding whether a topic is suitable or not; for example, a few years ago the study of the allotropes of carbon may have been thought to be trivial but this would not be the case today.

The following examples of titles for chemistry extended essays are intended for guidance only. The pairings illustrate that focused topics (indicated by the first title) should be encouraged rather than broad topics (indicated by the second title).

"Spectrophotometric determination of trace amounts of lead in drinking water" is better than "Water analysis".
"The kinetics of oxidation of iodine ions with hydrogen peroxide in acidic solutions" is better than "Chemical kinetics".
"The analysis of the red dyes present in different brands of tomato ketchup by thin layer chromatography" is better than "The use of chromatography to separate materials".
"Is it better to use dried animal manure as a fertilizer or as a fuel?" is better than "Combustion and nitrogen analysis".
"The effects of sugar-free chewing gum on the pH in the mouth after a meal" is better than "Acid-base chemistry".

Suggestions

Here is a list of suggestions for Science Investigations. Please add/amend/extend the list as you see fit. This is essentially a brainstorm ...

Non-coalescing drops

Some industries will mix liquids by cascading one liquid into another, assuming mixing will be complete. These drops may prevent complete mixing and need to be investigated.

Recent research has shed light on this phenomenon: The fast-moving shiny drops that skid across the surface of soapy water. Detergents play a crucial role – but how does the concentration of detergent affect the drops? What about ‘non-ionic’ detergents? What about a surface of anionic detergents and drops of cationic ones?

Challenges: Making drop-producing apparatus, Researching the chemistry of detergents, Assessing the numbers of drops

Thiosulphate/acid reaction (‘disappearing cross’)

Chemical engineers wishing to check if turbidity is a useful surrogate measurement for whether a reaction has reached completion.

How does the reaction respond to changes in acid concentration (it is first order for thiosulphate concentration but varies from first to zero order with acid).

How can we assess the amount of oil contamination on beaches?

Various groups will want to assess oil contamination, and a simple quick method would be appreciated.

The method used solvent extraction. Sand samples were laced with oil and the efficiency of recovery was measured. The sensitivity of the method was also estimated.

Synthesis and isolation of propanoic acid from propan-1-ol.

Chemical suppliers who want to investigate production of this chemical.

Trialling different methods.

Making biodiesel from waste vegetable oil.

Motoring enthusiasts who want to make their own environmentally-friendly and cheap fuel.

By using methanol and sodium hydroxide it is possible to make diesel fuel from old chip fat.

Analysing the gases remaining after burning a candle in a gas jar.

Motor vehicle engineers who want to check the composition of exhaust gases.

CO 2 is easy; it is readily absorbed with NaOH.

O 2 is harder; an oxygen probe is very useful but otherwise oxygen could be absorbed by, for example, the slow reaction of steel wool.

CO is challenging; it will be absorbed by CuCl solution but it is in very low concentrations.

Extraction of caffeine from tea.

Suppliers or independent analysts want to assess the caffeine content of tea products. Chemical suppliers want to provide pure caffeine to clients.

[1] This method usually involves solvent extraction with a chlorinated alkane (e.g. dichloromethane or 1,1,1,-trichloroethane). With care it is possible to recycle the solvent and avoid health and environmental damage.

Guide to the IB Extended Essay in 2024

January 24, 2024

If you’re an International Baccalaureate student getting ready to write your IB Extended Essay, you might be experiencing some very understandable trepidation. But have no fear—we’re here to help you understand what’s required of you, how to plan ahead (IB extended essay topics), and how you’ll be graded (IB extended essay rubric). Keep reading for a good dose of preparation and confidence before you begin the journey. In this article, we’ll cover:

What is the IB Extended Essay?

The ib extended essay—required content, ib extended essay topics.

IB Extended Essay—Sample Essays

IB Extended Essay Tips

Ib extended essay rubric, ib extended essay—more resources.

The IB Extended Essay is a 4,000-word paper that asks you to immerse yourself in research and academic writing. A required part of the IB program, the Extended Essay is a chance to dig deep into a topic that fascinates you.

Although it’s no small task, the IB Extended Essay is an opportunity to gain practical research and writing skills that will come in handy again in college. As you write, you’ll learn how to:

Identify credible sources
Formulate a research question and limit your scope of research
Communicate ideas to an audience
Develop a well-supported argument

The IB Extended Essay is largely an independent, self-directed project, but don’t worry—the IB program doesn’t throw you into the deep end. You do get to select a mentor (usually a teacher at your school) to help guide you through the process. As you write, you’ll be required to meet with your mentor three times. As part of your final evaluation, your mentor will interview you in a final reflection section called a viva voce . During the viva voce, your mentor will check for plagiarism and malpractice, ask you to reflect on challenges and difficulties, and prompt you to discuss what you’ve learned through the research and writing process. Your mentor will then generate a report that factors into your final grade.

Your final essay must include the following:

Contents page
Introduction
Body of the essay
References and bibliography

For this essay, it will be up to you to generate a topic; the International Baccalaureate does not provide prompts. However, your essay will need to fit within one of six provided subject areas . You’ll choose from the following list of IB Extended Essay Topics:

Language and literature
Language acquisition
Individuals and societies
Mathematics

IB Extended Essay Topics (Continued)

At a glance, the subject areas might look limited, but the topics you can choose to write about are actually wide-ranging. The “Individuals and societies” category includes social science topics like economics, history, world religions, and philosophy. And, if you’re leaning toward “Science,” you can choose from classic subjects such as biology, chemistry, and physics, or related topics like environmental systems or health science, among others.

The IB also offers a special “World Studies” option for students interested in researching global issues. This subject would allow you to center your writing on global issues such as migration, global health, cultural exchange, or climate change.

Wondering what an outstanding IB Extended Essay looks like? The International Baccalaureate provides quite a few sample student essays online . Here are five essays that earned A grades.

Language and literature: An exploration of an aspect of the narrative voice in Vladimir Nabokov’s Lolita

Environmental Systems and Societies: The economic impact of the 1995 reintroduction of grey wolves to Yellowstone National Park

Psychology: To what extent do social networking sites (SNS) usage lead to experience of anxiety in adolescents?

Music: Composition techniques in the 1st movement of Johannes Brahms’s Symphony No. 2, Op. 73

Business Management: Corporate Culture at Oracle

1) Pick something you’re passionate about

As you can see from the titles above, the IB Extended Essay is a great place to delve into a niche topic that fascinates you. Since you’ll be spending many months on this essay, you’ll want to pick a topic you genuinely enjoy spending time learning about. It’s also smart to choose something you’ve already learned about in your IB classes so that you have a strong foundation of knowledge to start with. In music class, do you love pondering why music makes us feel a certain way? Maybe an essay about music theory will keep your gears turning. Do you come alive trying to solve seemingly impossible problems in physics class? Now’s your chance to put those equations into action.

Since this essay is all about your academic interests, it’s also a good idea to pick a topic that’s relevant to what you plan to study in college. Selecting a relevant topic will provide you with significant exposure to the field and will also give you something meaningful to talk about in your college admissions essays.

2) Limit your scope

What’s the meaning of life? Why do wars happen? What is time? Some questions are just way too big to answer, and your IB Extended Essay is not a good place to tackle expansive, philosophical questions. Instead, think of this essay as a place to investigate one piece of a big question. If, let’s say, you’re generally interested in what helps women reach positions of leadership in business, this is a good place to examine how one or a few companies approach this issue. Or, if you’re interested in studying what inspires surrealist painters, you’ll want to pick one or a few painters to research, likely all from the same time period. For both these topics, you’d need a whole textbook to tackle the full question, but limiting your scope will make it much easier to write a clear and cohesive 4,000 words.

On the other hand, it’s possible to narrow your focus too much. It would be impossible, for example, to write 4,000 words about a single sentence in a novel. Make sure you talk about scope early and often with your mentor. Together, you can find the perfect Goldilocks scope for your project that’s not too big and not too small.

3) Choose a good mentor

Speaking of mentors, choosing wisely will help you enormously as you embark on your IB Extended Essay. You’ll want to make sure you choose someone with existing knowledge in your research topic. Your English teacher may be able to give you great writing advice, for example, but they won’t be able to guide your research and scope if you’re writing about marine animals or modern dance.

Before you approach a teacher, make sure you have at least one topic idea (or even a few ideas) in mind so that you can make sure they’ll be a good fit to supervise your project. When you meet with them, find out what their mentorship style is like. Make sure they’ll have time to read several drafts of your essays, meet with you a few times, and give you feedback. Some IB schools will require your IB Extended Essay mentor to sign an agreement form too, so make sure you find out what paperwork is required in advance.

4) Get organized, way organized

The IB Extended Essay is not something you can crank out the night before it’s due. The essay is meant to be a substantive, in-depth, thoughtful, and thoroughly researched analysis, and Rome simply isn’t built in a day. This might be the longest paper you’ve written to date, and this project might require more research than you’ve been asked to do before. Timelines vary by school, but you’ll likely spend between eight months and a year working on your IB Extended Essay. So, how will you pull it all off? For these 8-12 months, organization will be your guiding light. We recommend you:

Get started early. If your essay is due November of your senior year, start generating topic ideas during your junior year right after winter break.
Create a long-view schedule for yourself. What will you accomplish each month of your process?
Give yourself deadlines. Once you choose a mentor, suggest 2-3 draft deadline dates so that you will be held accountable throughout the writing process.
Find a note-taking system that works for you. You’ll be reading many articles and books and it’s hard to keep track of all your sources. Create a document or spreadsheet where you keep track of the sources you’ve found and check them off as you read. As you finish reading a text, type up important quotes and a few notes explaining how it connects to your topic and to your other texts.

5)Write a messy first draft

Writing never comes out perfect the first time, even for New York Times bestselling authors and the most experienced researchers. In your first draft, give yourself permission to get all your thoughts out, no matter how unstructured or rambling they are. Call this your brainstorming draft. When you’re ready to revisit it, see what patterns emerge, what common ideas you can group together, what beginning buds of ideas you can make bloom into full-fledged analysis.

6) Communicate for an audience

When you’re used to producing writing that only your teacher reads, it can be hard to remember to write for an audience. But at the end of the day, writing is communication , and the best writing is clear and thorough communication that anyone could pick up and read. For your IB Extended Essay, you’ll want to remember that many people will be reading your final essay, and not all of them will be experts in the niche topic you choose to study. Ask yourself: how can I explain my research to an audience who doesn’t already agree with my analysis?

To communicate to an audience, you’ll want to:

Provide lots of general background information on your topic.
Don’t assume your reader is familiar with your sources. Introduce them as if they’re guest speakers about to walk up to a podium and deliver a lecture.
After including quotes, facts, and figures, be sure to explain what those sources mean in your own words and how they connect to your bigger-picture argument.
Don’t assume your arguments are self-evident. In this essay, communicating for an audience means supplying ongoing interpretation and analysis, even if it feels like you’re explaining the obvious. Your reader isn’t on your research journey with you, so your points might not be so obvious to your reader.

Although your IB Extended Essay provides a report that factors into your grade, your essay will also be assessed by external examiners the IB. Per the IB Extended Essay Rubric , essays are graded on a scale from 0 to 34 based on 5 different criteria:

Criterion A: Focus and Method (6 points maximum)
Criterion B: Knowledge and Understanding (6 points maximum)
Criterion C: Critical Thinking (12 points maximum)
Criterion D: Presentation (4 points maximum)
Criterion E: Engagement (6 points maximum)

As you can see, Critical Thinking is the most significant rubric category. This means that the IB wants to see you arrive at your own unique analysis of your topic, drawing connections between sources and data, and making well-supported arguments. This means they want a lot of you: your ideas, your interpretations, your thoughts. Make sure you emphasize that in your essay, but of course don’t forget the other categories.

The score a student receives corresponds to a letter grade scale that is slightly different than what we’re accustomed to in the U.S. Here’s the letter grade to numerical score breakdown:

Total Points Earned	Letter Grade	Descriptor
30-34	A	Excellent
25-29	B	Good
17-24	C	Satisfactory
9-19	D	Mediocre
0-8	E	Elementary

You must earn a D or higher to receive your IB Diploma. To learn more about the different criteria included in the IB Extended Essay Rubric, you can explore the IB’s full guide to the Extended Essay .

Notes from the IB

RE: Research Question and Title of Extended Essay

Please note the statement below from the EE curriculum manager regarding the need to have both a title and a RQ for all subjects. Previous versions of the EE Guide indicated that the title and the RQ should be the same for History, Business Management and Mathematics. This is no longer the case. All essays, regardless of the subject, need to have both a RQ and a title.

Hi Kathy,

To answer your question, I am going to quote directly from a response John Royce provided, on this forum, in October in response to a very similar question: (it was a question about using Spanish sources - hence the mention of Spanish)

It is certainly permissible to use sources which are not in the language of the essay, but translation into the target language is required , one cannot assume that the reader understands the original language.

It is usual to quote the original as well as presenting the translation. [Do not put quotation marks around your translation, just around the original]

Umberto Eco argues ("in Mouse or rat?") that direct translation may lose meaning, paraphrase or use of different idioms may be required to get the ideas across. Paul Bellos ("Is that a fish in your ear?") makes a similar argument - direct translation may confound meaning... Direct translation may not be ideal - meaning and understanding are preferred - so, not to worry that your student with her good Spanish cannot present a direct translation.

What must be made clear is that the translations are those of the student; these are her understandings. Readers can make of that what they will - and if unsure, are presented with the original - they can seek another translation. A note in the acknowledgements and/or in the introduction to the effect that all translations are those of the writer is ... essential.

In response to the question about the Bibliography/Works cited, my preference would be to list the source in its original Thai version, but perhaps with the English in brackets, to help the examiner.

Your bibliography will have the entries in Thai characters first in the document. Any in-text citation to Thai sources will be in (Thai characters [English translation]).

Citation in Thai [English translation]

Works Cited Example:

วงษ์ปัญญา, ธนกร [Wongpunya, Thanakorn]. “โรงงานยาสูบรวยแค่ไหน และเอาเงินไปทำอะไรบ้าง.” [How rich is the Thailand Tobacco Monopoly and where does the money go?] (candidate translation). The Standard, The Standard, 30 Aug. 2018, thestandard.co/thailand-tobacco-monopoly/.

Format of the Extended Essay

Required Formatting

The extended essay should be written in a clear, correct and formal academic style, appropriate to the subject from which the topic is drawn. Given that the extended essay is a formally written research paper, it should strive to maintain a professional, academic look.

To help achieve this, the following formatting is required:

12-point, readable font (Calibri or Times New Roman);
double spacing throughout entire Essay;
page numbering - top right corner;
no candidate or school name or supervisor name on the title page or page headers.

Submitting the extended essay in the required format will help set the tone of the essay and will aid readability for on-screen assessment by examiners.

Required S tructure

The structure of the essay is very important. It helps students to organize the argument, making the best use of the evidence collected.

There are six required elements of the final work to be submitted. More details about each element are given in the “Presentation” section. Please note that the order in which these elements are presented here is not necessarily the order in which they should be written.

Six required elements of the extended essay:

Contents page
Introduction
Body of the essay
References and bibliography -- if MLA "Works Cited" if CSE "References"

1. Required Title Page

The title page should include only the following information:

the title of the essay
the research question
the subject the essay is registered in (if it is a language essay also state which category it falls into; if a world studies essay also state the theme and the two subjects utilized)

The upper limit is 4,000 words for all extended essays.

2. Required Contents Page

A contents page must be provided at the beginning of the extended essay and all pages should be numbered. Please note that an index page is not required and if included will be treated as if it is not present.

3. Required Introduction

The introduction should tell the reader what to expect in the essay. The introduction should make clear to the reader the focus of the essay, the scope of the research, in particular an indication of the sources to be used, and an insight into the line of argument to be taken.

While students should have a sense of the direction and key focus of their essay, it is sometimes advisable to finalize the introduction once the body of the essay is complete.

4. Required Body of the Essay (research, analysis, discussion, and evaluation)

The main task is writing the body of the essay, which should be presented in the form of a reasoned argument. The form of this varies with the subject of the essay but as the argument develops it should be clear to the reader what relevant evidence has been discovered, where/how it has been discovered and how it supports the argument. In some subjects, for example, the sciences, sub-headings within the main body of the essay will help the reader to understand the argument (and will also help the student to keep on track). In structuring their extended essay, students must take into consideration the expected conventions of the subject in which their extended essay is registered.

Once the main body of the essay is complete, it is possible to finalize the introduction (which tells the reader what to expect) and the conclusion (which says what has been achieved, including notes of any limitations and any questions that have not been resolved).

Any information that is important to the argument must not be included in appendices or footnotes/endnotes. The examiner will not read notes or appendices, so an essay that is not complete in itself will be compromised across the assessment criteria.

5. Required Conclusion

The conclusion says what has been achieved, including notes of any limitations and any questions that have not been resolved. While students might draw conclusions throughout the essay based on their findings, it is important that there is a final, summative conclusion at the end. This conclusion(s) must relate to the research question posed.

6. Required References & Bibliography

Students should use their chosen style of academic referencing as soon as they start writing. That way they are less likely to forget to include a citation. It is also easier than trying to add references at a later stage. For more information on this, refer to the guidelines in the IB document Effective citing and referencing.

Writing the essay takes time but if students have used their Researcher's reflection space and reflection sessions in a meaningful way they should be well prepared to develop their arguments.
