IB word count rules explained: IAs and Extended Essay
IB Diploma Programme · Internal Assessment · Extended Essay
Word count in IB assessments is not a guideline you can stretch. Examiners are instructed to stop reading at the stated limit, which means anything you write beyond it, including your conclusion, your strongest piece of analysis, your final evaluation, simply does not exist as far as marking is concerned. This guide explains the limits for every common subject, exactly what counts toward them, and how to manage your word budget effectively from the first draft.

Why word count is a hard rule, not a soft one
Many students treat word count as a rough target rather than a ceiling. This is a costly mistake.
IB policy is explicit: examiners will not read or assess any content beyond the stated word limit. If your IA is capped at 2,200 words and your conclusion begins at word 2,350, your conclusion will not be marked. If your evaluation of sources in your EE runs past 4,000 words, it will not be considered. You do not receive partial credit for the excess. It is simply ignored.
The consequence is not just a deduction. Depending on where the cutoff falls, you could lose marks across multiple assessment criteria simultaneously: evaluation, analysis, and conclusion all in one go.
Writing too little carries a different risk. Work that falls significantly short of the expected range typically signals insufficient depth, analysis, or development of argument. Examiners assessing criteria like "critical thinking" or "evaluation" will find limited evidence to reward if the work is substantially under-length.
