The moment you realize your IA is not “just coursework”
You’re revising for exams, minding your own business, and then someone says, “Don’t forget your IA.” Suddenly it feels like your calendar gets louder. That’s because an IA (Internal Assessment) isn’t a side quest in IB. It’s part of your final grade, it’s assessed using a rubric, and it’s one of the few times you can earn marks through sustained thinking instead of exam-day adrenaline.
In simple terms: an IA is work you complete during the course, marked by your teacher and then moderated by the IB to keep grading fair across schools. Done well, your IA can raise your overall result and reduce pressure on exam papers.

IA overview checklist (what you actually need to know)
Before you go deep, keep this IA checklist in your notes:
Your teacher marks your IA using official criteria
The IB moderates samples to align grading standards
The format depends on the subject (experiment, exploration, oral, portfolio, report)
Most IA success is rubric alignment + clear evidence
Starting earlier beats “being smarter” later
If you want a subject-by-subject starting point, use the IB IA Guides hub.
What is an IA in IB, exactly?
An IA is the internal component of many IB subjects. “Internal” means your teacher assesses it, but that doesn’t make it casual. Moderation means the IB checks a sample of work to make sure standards match globally.
A helpful way to think about the IA is as your proof of skill. Exams reward speed under pressure; an IA rewards decision-making over time: choosing a focused question, collecting evidence, and explaining what the evidence means.
Your IA changes shape depending on the course, but the logic stays the same: investigate something specific and communicate it clearly.
Common IA formats
Sciences (Biology, Chemistry, Physics): an investigation with data, analysis, and evaluation
Math (AA/AI): a mathematical exploration (often modeling or pattern-based)
Individuals and Societies: research-based report, essay, or analysis task
Languages: often an assessed oral or portfolio-style component
Arts: portfolio + reflection process

Why the IA matters for exams (even if it’s not an exam)
Most students underestimate the IA until it’s late. Then they realize it’s not only worth a meaningful portion of the grade, it also trains the exact thinking exams reward: precision, justification, evaluation, and clear academic writing.
A strong IA can also stabilize your final outcome. If exam revision goes slightly off-plan (it happens), your IA mark can protect you.
How to do well in your IA (without living in Google Docs)
A good IA isn’t “long.” It’s deliberate.
A simple strategy that works
Pick a topic you can explain to a friend in 60 seconds
Build everything around the criteria language (not vibes)
And if you want tools that make this faster, RevisionDojo is built for it: use the Coursework Library for models, Grading tools for rubric-aware feedback, and AI Chat when you’re stuck but don’t want to lose an hour.

Using RevisionDojo to support your IA and exam prep
The hidden stress of an IA is context switching: drafting, checking criteria, finding exemplars, then jumping back to exam revision. RevisionDojo reduces that.
An IA length depends on the subject and the task type, so there isn’t one universal number that fits everyone. Some science IAs are written reports with data processing and evaluation, while language components may be oral-based and have very different “length” expectations. What matters most is not how much you write, but whether each section earns marks against the criteria. Students often lose time by adding extra description that doesn’t improve the rubric score. A good habit is to draft, then highlight each paragraph and ask: “Which criterion is this serving?” If you can’t answer, it’s probably not helping your IA.
Can I get help on my IA?
Yes, you can get guidance, but the final IA must remain your own work and your own thinking. In practice, that means teachers can explain criteria, suggest you narrow your research question, and give feedback on clarity. What they cannot do is rewrite your work or tell you exactly what to say to hit a specific mark band. A safe approach is to ask for feedback in questions: “Is my method valid?” “Is my analysis linked to my question?” “Where is my evaluation too vague?” Tools can also support your independence: RevisionDojo’s AI Chat can help you understand concepts, and the Grading tools can show where evidence is missing without writing the IA for you. Used properly, help should make your decisions sharper, not replace them.
When is the IA submitted?
Your IA deadline is set by your school, not by a single global date you’ll find online. Schools create internal deadlines so teachers have time to give feedback, mark work, and prepare moderation samples. That’s why two students in different schools can have completely different submission weeks. The smartest move is to treat the school deadline as a final deadline, and create a personal deadline 2--3 weeks earlier for a near-finished draft. That buffer is where marks are gained: tightening the research question, improving analysis, and fixing presentation issues. If you wait until the last week, your IA becomes a typing contest instead of a scoring strategy. Planning early also protects exam revision time later.
Final thoughts: your IA is a grade you can control
The IA is one of the fairest parts of IB, even though it doesn’t always feel like it. You get time, feedback, and multiple chances to make your thinking clearer. If you treat your IA like a rubric puzzle (not a motivation test), it becomes manageable and surprisingly satisfying.
When you’re ready to move from “I hope this is fine” to “I know where the marks are,” use RevisionDojo’s IA Guides, Coursework support, Grading tools, and exam prep loop (Questionbank, Study Notes, Flashcards, AI Chat, Predicted Papers, Mock Exams, and Tutors). Your IA shouldn’t steal your exam season--it should strengthen it.
