IB Extended Essay Grader — Free AI Feedback on Your EE

IBLens grades your IB Extended Essay against the official IB EE rubric — all five criteria — and gives you criterion-by-criterion feedback in 60 seconds.

Which criteria apply to you? Sessions through November 2026 use the 34-mark EE criteria below. The May 2027 cohort (students who began the DP in 2025 — including current drafts) is assessed on the new 30-mark criteria (Framework 6, Knowledge 6, Analysis and line of argument 6, Discussion and evaluation 8, Reflection 4). Select your session in the analyzer.

IB Extended Essay rubric: five criteria (34 marks)

• Criterion A — Focus and Method (6 marks): The clarity and focus of your research question, the appropriateness of your methodology, and how well you demonstrate awareness of your approach. IBLens checks whether your research question is arguable, specific, and suitable for an extended investigation.
• Criterion B — Knowledge and Understanding (6 marks): Depth of subject-specific knowledge, correct use of terminology, and understanding of the academic context. IBLens checks whether you use subject-specific vocabulary accurately and whether your engagement with existing research is genuine.
• Criterion C — Critical Thinking (12 marks): The quality of your argument, the strength of your analysis, the handling of counter-arguments, and the logical structure of your reasoning. This is the highest-weighted criterion — IBLens gives detailed feedback on argument quality.
• Criterion D — Presentation (4 marks): Adherence to the required structure (title page, table of contents, introduction, body, conclusion, bibliography), the 4,000-word limit, and formatting. IBLens checks structure and approximate word count.
• Criterion E — Engagement (6 marks): Assessed through your Reflections on Planning and Progress (RPPF). IBLens evaluates the depth of your intellectual engagement and self-reflection demonstrated in your written work.

Common Extended Essay mistakes IBLens catches

• Research question too broad or descriptive: "What is the impact of social media?" cannot be argued in 4,000 words. IBLens checks whether your research question is narrow enough for genuine analysis.
• Descriptive body sections: Summarising sources instead of building an analytical argument. Every paragraph in the body should advance your answer to the research question.
• Weak conclusion: Conclusions that introduce new evidence or simply restate the introduction. Your conclusion must directly and specifically answer your research question based on your argument.
• Unbalanced criterion C: Having good analysis but no counter-argument, or good counter-arguments but no sustained position. IBLens checks for both.
• Over the 4,000-word limit: examiners stop reading at 4,000 words — anything beyond is not assessed. There is no official minimum, but very short essays rarely sustain enough analysis. IBLens checks your word count.
