The scariest part of writing an Extended Essay isn’t the 4,000 words. It’s the feeling that somewhere, someone you’ll never meet will read your work and decide how much it’s worth.
That instinct is right. In the IB, the Extended Essay (EE) is marked externally. And once you understand what that actually means, the EE becomes less mysterious and more manageable, like any other exam-style task: learn the criteria, practice the skill, tighten the draft.

Is the IB Extended Essay marked externally?
Yes. The IB Extended Essay is assessed by external IB examiners using standardized criteria.
Your school supports the process, but it doesn’t decide your final mark. Your supervisor guides you, checks that the work is your own, and completes required reflections with you. But the final assessment is external, which is why the EE can feel like it belongs to the wider IB world, not just your classroom.

The EE marking process (a quick checklist)
Here’s the EE journey in plain terms for IB students preparing for exams:
-
You choose a subject and research question (and adjust it as you learn).
-
A supervisor supports you with guidance and formal reflection checkpoints.
-
You submit the final EE through your school.
-
An external IB examiner marks it against the published criteria.
-
Your EE grade contributes to core points (together with TOK).
A simple way to stay calm: treat it like an exam paper you draft over months. The criteria are the markscheme. The draft is your practice.

What your supervisor does (and doesn’t do) in IB
In the IB, the supervisor is more like a coach than a grader.
What they do:
-
Help you narrow your topic into a researchable question.
-
Give feedback on direction, structure, and academic honesty.
-
Guide your reflections (including the viva voce).
What they don’t do:
-
Decide your final grade.
-
“Fix” the essay for you.
-
Mark it like an internal assessment.
That division matters. Because if you’re aiming for a top band, you have to learn to self-edit like an examiner would read: precise, skeptical, and criterion-driven.

Why external marking is a good thing (even if it feels intimidating)
External marking protects you.
It means your EE is judged by the same global IB standard as everyone else. A strong essay from a small school can score just as well as a strong essay from a famous one. And because examiners use shared criteria, the biggest advantage isn’t having “inside knowledge”; it’s having clarity.
That’s also why tools that mirror examiner logic matter. RevisionDojo’s IB Extended Essay (First Assessment 2027) Grader and the wider IB Coursework Grader can help you check whether your draft reads like analysis (high marks) or like a well-written summary (lower marks).
How to prepare for external marking while still studying for IB exams
The EE can quietly steal time from exam prep. The fix isn’t heroic effort. It’s systems.
A practical rhythm many IB students can sustain:
-
Use short, consistent EE blocks (45-60 minutes) instead of weekend marathons.
-
Use feedback loops: draft a section, check criteria, revise only what moves marks.
-
Keep exams moving with daily recall and practice.
RevisionDojo is built for that split-brain season. You can revise your subjects with Questionbank, lock in memory with Flashcards, and use AI Chat to get unstuck fast, while your EE improves through rubric-based grading tools and the Coursework Library.

Closing: treat the EE like a transparent system
So, is the IB Extended Essay marked externally? Yes, and that’s not a threat. It’s a system.
When you write for external marking, you stop guessing what the reader wants and start building what the criteria reward. And when you run that process alongside exam revision, using RevisionDojo’s Questionbank, Study Notes, Flashcards, AI Chat, Grading tools, Predicted Papers, Mock Exams, Coursework Library, and Tutors, the EE becomes less like a foggy side quest and more like a controlled project you can actually finish well.
