General Deadline for IB Extended Essay Submission 2025

So, what is IB extended essay deadline? You should consider that the official deadline is always set by the International Baccalaureate Organization yearly. Those who graduate in May 2025 must submit their papers by March 15, 2025. You should bear in mind that the deadline is universal for all students, no matter what school they attend. Another requirement is to submit essays electronically through the IB coordinator of the school. 

At the same time, schools tend to set their internal deadlines, and they are usually earlier than the official IB submission date. The thing is that they want to make sure that students get enough guidance from their supervisors and have enough time for feedback and revisions. Another reason for such a decision is that the school has sufficient time to prepare the required documentation for the IB submission. 

Therefore, you must manage your time and keep track of the internal extended essay deadline for submission and the official one. It is also important to work closely with your coordinator and ask for help from a reliable writing agency, such as Writing Metier, whenever you need assistance. 

Important Milestones Leading to the Final Submission

When is IB extended essay deadline? The truth is that completing this assignment is a long process that can take a few months, and you need to meet several milestones along the way. Even though different schools might have a little bit different schedules, there is a general timeline of the major stages in the process. 

1. Topic Selection and Approval 

This is the first step of the writing process, and you should do that 10-12 months before the final submission. It is important for you to consider your interests and the requirements of the IB subject area at this point. The process includes the following steps:

• Research and reflection. Students are encouraged to start considering potential topics as early as possible so that they do not fail to meet the early submission deadline. Ideally, this stage should begin in the spring or summer of the year before the final submission (around May- June 2025 for students graduating in 2026).
• Finalizing the research question. As soon as the general topic has been chosen, you must develop a clear and focused research question. This is one of the most important steps in the process because the research question will guide the entire research project. The question should be specific, researchable, and feasible, given the resources available to you.
• Supervisor approval. After you finalize the topic, you need to introduce your proposed research question to your supervisor for approval. Depending on the school, this approval might need to be finalized by October 2025.

Writing an extended essay in economics makes it even more crucial to ensure that your research question is focused and data-driven.

2. Research and Drafting

The next step is research and writing the first draft, and this usually happens 6-8 months before the final submission. During this stage, you should do the following:

• Perform research. Meeting the IB deadline for extended essay is critical, but it is equally important to make sure that the content is worthy. It means that you will spend a lot of time reading, gathering sources, and organizing data. You should also make sure that your sources are credible, academic, and relevant to your research question. 
• Craft an outline. After you finish your initial research, you need to craft an outline of your essay. It is recommended not to skip this step because it serves as a road map to organize the information and create a good structure for your paper. 
• First draft. You should write the first draft of your essay and submit it for feedback by December 2025 or early January 2026. At this point, your paper does not need to be ideal, but it should comprise a clear argument, evidence, and an introduction to the methodology and research question.

If you are working on your TOK essay during this period, the same principles apply: draft early, structure well, and back up your claims.

3. Feedback and Revision

This step is not about the final extended essay IB deadline because it should take place 4-6 months before the final submission. At this point, you will receive constructive suggestions and comments for improvement. It means that you will most probably have to:

• Revise the essay. You should use the feedback to refine your arguments, enhance your analysis, and make the necessary adjustments to your evidence or thesis. This process tends to involve reworking sections of the paper to make sure that it meets IB standards. 
• Check citations and formatting. You should ensure that you are adhering to the appropriate citation style, such as MLA, APA, or Chicago. Your bibliography should also be properly formatted. 
• Second draft submission. You should submit the revised draft to your supervisor for further feedback by January or February 2026. 

4. Final Draft and Submission to the School

You should perform this step 1-2 months before the IB extended essay submission deadline. The final draft should introduce a well-researched, coherent, and academically rigorous paper that addresses your research question. You will most probably be required to do that around late February to early March 2026. This is the final review of your essay, so it is critical to work closely with your supervisor during this period to finalize your paper and solve any last-minute issues. 

5. Viva Voce and Reflection

As soon as the final draft is introduced, you will have a viva voce (oral reflection) with your supervisor, which usually happens 1-2 months before the final submission deadline. This step is an opportunity for you to reflect on your research process, the challenges you dealt with, and how you have grown academically during the course of the EE.

6. Final IB Submission

After you complete the final revisions and viva voce, the final version of the assignment must be submitted to the IB for assessment. You should bear in mind that the official extended essay submission deadline is March 15, 2026. However, schools do their best to send their students` papers in advance of this date to make sure that all paperwork is filed properly and avoid any last-minute issues. 

Recent Extended Essay Process Changes

In recent years, the IB has introduced a few changes aimed at improving the quality of student research and adding more flexibility in picking research topics. Further, you can find some of these changes:

1. Interdisciplinary research. Students are now allowed to follow an interdisciplinary approach to their research. Thanks to this, you can draw on multiple IB subject areas and explore complex, interconnected topics. This option was created to help students develop broader research skills and connect different academic disciplines. 
2. World Studies extended essay. Before that, a separate category, the World Studies extended essay, now falls under the interdisciplinary approach. It means that you can explore global issues by adding two or more subject areas, which improves the scope of your research and develops critical thinking. 
3. Reflection component. The viva voce, or reflection session with the supervisor, has become an even more integral part of the EE process. It allows students to demonstrate their engagement with the research process and their ability to reflect on their learning journey before meeting the IB deadline for extended essay.
4. Assessment criteria updates. The IB has updated the assessment criteria for TOK essays and extended essays to emphasize the importance of critical thinking, synthesis of information, and clarity of argumentation. These updates aim to ensure that students engage in rigorous research and produce work that is both academically sound and well-organized.
