Extended Essay deadlines are set individually by each school, not by a single universal IB-wide date, which means your actual timeline depends on your school’s internal schedule — but nearly all schools follow a broadly similar structure across the two years of the Diploma Programme. Planning around this structure early is one of the most effective ways to avoid a rushed, lower-quality final essay.
Why School-Set Deadlines Matter More Than the Final IB Deadline
The IB itself sets a final submission deadline for your school to upload all Extended Essays, but your actual working deadlines — topic selection, first draft, supervisor meetings, final draft — are set internally by your school’s EE coordinator, usually well ahead of the IB’s own cutoff to allow time for review and formatting checks.
A Realistic Extended Essay Timeline
Term 1 of Year 12 (first year of the DP) Subject and general topic area selection. This is the ideal window to start narrowing broad interests into a potential research focus, using resources like a topic ideas list to begin exploring options.
Term 2 of Year 12 Refining your research question and being formally assigned a supervisor. This is also the point to begin initial research and confirm that sufficient sources or data are genuinely accessible for your chosen topic.
Term 3 of Year 12 / Summer Before Year 13 Most schools expect a substantial first draft, or at least the completed research and data collection phase, to be finished before the summer break — this is often the single most important checkpoint, since students who complete real drafting work over the summer consistently submit stronger final essays.
Term 1 of Year 13 (final year) Completing your first full draft and receiving structured feedback from your supervisor, ideally against the actual assessment criteria (see our guide on how the Extended Essay is graded) rather than just general comments.
Term 2 of Year 13 Final revisions, formatting checks (title page, word count, referencing style), completing your Reflections on Planning and Progress Form (RPPF), and final internal school submission — typically several weeks before the IB’s own final upload deadline to allow your school time to process all essays.
Why Starting Early Matters More Than in Other IA Components
Unlike a single-subject Internal Assessment, the Extended Essay is an independent 4,000-word research project with no scheduled class time dedicated to it in most schools. This means poor time management compounds far more severely — a few missed weeks early on often becomes an unmanageable crunch by the final term, when Year 13 workload (university applications, other IA deadlines, final exam preparation) is at its heaviest.
Common Timeline Mistakes
- Waiting until Term 1 of Year 13 to seriously start research, leaving insufficient time for genuine analysis and revision
- Treating the summer between Year 12 and Year 13 as a break rather than the most valuable uninterrupted research and drafting window available
- Not scheduling regular supervisor meetings, resulting in feedback arriving too late to meaningfully improve the final draft
- Underestimating how long formatting, referencing, and the RPPF actually take once the analytical writing is finished
How to Build Your Own Working Timeline
Ask your EE coordinator for your school’s specific internal deadlines at the very start of Year 12, then work backward, setting your own personal milestones roughly two to three weeks ahead of each official deadline — this buffer consistently prevents the last-minute scramble that produces weaker final essays.
Final Tip
Treat the summer between Year 12 and Year 13 as your most valuable Extended Essay resource. Students who use it for serious drafting — not just “starting” — consistently submit stronger, more analytically developed essays than those who wait until term time resumes.
