Which IB Subjects Have an IA? The Complete Guide

The IA moment every IB student recognizes

It usually starts innocently.

You're revising for exams, feeling almost responsible, when someone says a sentence that changes the weather in your brain: "Don't forget your IA."

Because an IA isn't just "coursework." It's a deadline that creeps. It's a rubric that reads like a foreign language until it suddenly doesn't. It's also one of the few places in IB where your curiosity can genuinely help your grade.

So let's answer the question clearly: which IB subjects have an IA? And more importantly, what does that mean for your exam prep, your time, and your stress levels?

Quick checklist: how to tell if your subject has an IA

Use this fast checklist before we go subject-by-subject:

• If your subject includes an investigation, project, fieldwork report, oral, or portfolio, it almost always counts as an IA (or an internally assessed component).
• Most Group 4 sciences have a formal IA investigation.
• Maths has a formal IA exploration.
• Many Individuals and Societies subjects include a formal IA (often a report, essay, or investigation).
• Language courses usually have an internal component (often an oral), even if your school doesn't casually call it an "IA."

When in doubt, your safest move is to treat any internally marked, externally moderated task as part of your IA workload.

Which IB subjects have an IA?

Below is the practical, student-focused map. The exact format varies by syllabus and subject guide, but these are the core patterns IB students see year after year.

Group 4: Sciences (Yes, these have an IA)

If you take a science, you're in classic IA territory.

Common Group 4 subjects with an IA include:

• Biology
• Chemistry
• Physics
• Environmental Systems and Societies (ESS)
• Sports, Exercise and Health Science (SEHS)
• Computer Science (project-style IA)

The science IA is usually an investigation where you design or run a method, collect or source data, process it, and evaluate limitations. Even when the data is secondary, the thinking still has to be yours.

If you're taking ESS, RevisionDojo's guide library shows how the IA is judged in real rubric language: IB Environmental systems and societies (ESS) IA Guide.

And if Computer Science is your subject, you'll want a clearer breakdown of what the examiner expects from the build and evaluation: IB Computer Science Internal Assessment (IA) Ultimate Guide.

Group 5: Mathematics (Yes, maths has an IA)

Maths has an IA in both AA and AI.

Instead of a lab investigation, your maths IA is an exploration: a structured piece of mathematical thinking that shows personal engagement and clear communication. The trap is thinking it's "just a write-up." The reality is that it's scored like a performance: your maths choices, reasoning, and reflection all matter.

RevisionDojo keeps maths IA support close to practice and feedback. If you want to see how RevisionDojo frames IA prep inside the subject hub, start here: IB Math AA Internal Assessment (IA).

You can also drill concepts while keeping the IA alive using active recall tools like: Math AI Internal Assessment (IA) Flashcards.

Group 3: Individuals and Societies (Many have an IA)

Group 3 is where students often get surprised. Many of these subjects include a formal IA, but the format can look like an essay, a report, a study, or fieldwork.

Common Group 3 subjects that typically include an IA or internal investigation include:

• History
• Geography
• Economics
• Business Management
• Psychology
• Global Politics

The core skill is the same: you're being judged on how you build an argument from evidence, not how many facts you can stack.

Group 6: The Arts (Usually internally assessed components)

Arts subjects often have substantial internally assessed work (think process portfolios, exhibitions, performances, reflective work). Students sometimes don't call it an IA day-to-day, but the workload behaves like one.

The key difference is that the "evidence" is often your process: drafts, experimentation, reflection, and curation. That makes it feel personal, which is good. It also makes procrastination costlier, because you can't manufacture a process overnight.

Group 1 and Group 2: Studies in Language and Literature and Language Acquisition (Internal components)

Languages almost always include an internally assessed component (commonly an oral). Whether your cohort calls it an IA or not, it functions like one: teacher assessed, criteria-based, moderated.

Treat it like an IA anyway, because the same rules apply:

• your performance needs structure,
• your evidence needs to be traceable,
• your teacher feedback matters most when you use it early.

A quick way to think about IA types (so you revise smarter)

A useful mental model is to group your IA into one of these buckets:

Investigation-style IA

Common in sciences and ESS.

You need:

• a focused research question
• a method you can justify
• data handling that shows control and honesty
• evaluation that reads like a scientist, not an apology

Exploration-style IA

Common in maths.

You need:

• a clear aim
• maths that is appropriate and explained
• a narrative of reasoning (not just steps)
• reflection on choices and limitations

Argument/report-style IA

Common in humanities.

You need:

• a tightly framed question
• evidence that is selected, not dumped
• analysis that connects back to the question
• structure that makes moderation easy to follow

In other words: the IA isn't just content. It's decision-making under criteria.

How your IA should change your exam revision plan

Most students separate "IA time" and "exam time" like they're different seasons. That's why March and April feel like being chased.

A calmer approach is to make your IA feed your exam prep.

Use the IA to choose what to revise

Your IA reveals your weak skills faster than any checklist:

• If your evaluation is thin, you probably need more practice with command terms and justification.
• If your data processing is messy, you probably need more fluency with graphs, uncertainty, statistics, or interpretation.
• If your discussion feels descriptive, you likely need practice turning evidence into claims.

RevisionDojo is built for that feedback loop. You can:

• learn content fast with Digital IB Study Notes
• test yourself in the Questionbank
• turn sticky definitions into spaced repetition with Notes + Flashcards + Question Bank (Free)
• ask Jojo AI Chat the exact question your teacher doesn't have time to answer twice

Grade your draft like an examiner would

A quiet advantage is treating your IA draft like an exam script: criteria first, feelings second.

RevisionDojo's grading tools and rubrics make that easier because they force you to look at the work the way moderation does. If you want a concrete example, explore one of the live rubric graders such as: IB Design Technology SL IA Grader.

Build deadlines that create momentum

A useful rule: your IA needs more small deadlines than big ones.

Try:

• topic locked
• research question locked
• method/design locked
• data collected
• first analysis
• first full draft
• rubric self-grade
• final proof and authenticity checks

That last part matters because the IB moderation process rewards clarity and consistency. You're not just writing. You're making your thinking easy to verify.

A mini guide: using RevisionDojo to finish your IA without losing exam marks

Here's a simple workflow that matches how high-scoring students actually operate:

Build your IA foundation

• Start with RevisionDojo's IB Internal Assessment Guides to understand what the criteria reward.
• Look at exemplars when you need to calibrate quality (for example: Chemistry IA Exemplars or IB ESS IA Exemplars).

Draft with feedback loops, not heroic all-nighters

• Use Study Notes to tighten background theory quickly.
• Convert your own draft notes into Flashcards to retain key definitions and evaluation language.
• Use Jojo AI Chat to sanity-check logic, variable control, structure, and clarity.

Keep exam readiness growing in parallel

When you're deep in IA writing, it's easy to stop practicing exam questions. That's the hidden cost.

So keep a minimum exam routine alive:

• 20--30 minutes of Questionbank practice after each IA session
• one timed session weekly using mock-style practice (RevisionDojo supports this across subjects)

FAQ

Do all IB subjects have an IA?

Not all IB subjects have a component that students casually call an IA, but most subjects include some form of internal assessment or internally assessed work. The safest assumption is that if your subject has a teacher-marked task that is moderated externally, it behaves like an IA in planning and importance. What differs is the format: sciences often use an investigation, maths uses an exploration, and languages often use an oral. That variation makes students underestimate the workload, because it doesn't always look like a traditional report. If you're unsure, check your subject's assessment components and ask your teacher what is internally assessed. Treat it like an IA anyway, because the time management logic is the same.

How much does the IA matter for my final grade?

An IA is rarely "just a small percentage" in the way it feels during the first draft. In many subjects it is a meaningful chunk of the final grade, and it's one of the few opportunities to earn marks outside timed exam pressure. That matters because exam-day performance is noisy: stress, timing, and one tricky question can swing a grade. A well-executed IA can stabilize your overall result and buy you breathing room in the exams. It also develops skills the exams reward, like evaluation, clear structure, and evidence-based reasoning. If you want to feel how criteria translate into marks, RevisionDojo's IA guides and grading tools help you read your work like an examiner.

Can I use my IA topic to revise for exams?

Yes, and you should. The best students treat the IA as a concentrated study of one small corner of the syllabus, then expand outward into exam practice. Your background theory becomes revision notes, your method becomes applied understanding, and your evaluation becomes command-term training. The trick is to avoid letting the IA narrow your revision too much: pair each IA session with short Questionbank practice on adjacent topics. That way, your brain keeps the broader map while your IA builds depth. RevisionDojo makes this easier because Study Notes, Flashcards, and the Questionbank sit in one loop, so you can move from "understand" to "apply" quickly. Over time, your IA stops feeling like a separate monster and starts feeling like structured preparation.

What if my IA is not going well and exams are close?

First, separate quality from panic. A struggling IA usually means one of three fixable problems: the question is too big, the evidence/data is too weak, or the structure doesn't match the rubric. Your fastest improvement comes from re-aligning to criteria and cutting scope, not adding more pages. Next, protect your exam readiness with a minimum viable routine: small daily Questionbank sets, quick flashcard reviews, and one timed session weekly. Then fix the IA using focused milestones: clarify the research question, rebuild the method/argument spine, and rewrite the analysis to directly answer the question. If you need an outside mirror, RevisionDojo's AI Chat and grading tools can help you spot where marks are leaking without guessing. The goal is calm triage: stabilize the IA, keep exams moving, and stop doing work that the rubric will not reward.

Bringing it home: your IA is a strategy, not a side quest

The IB is full of big moments, but the IA is the quiet one. It's not done in a gym hall. No invigilator collects it with dramatic finality. You build it in ordinary afternoons, and that's exactly why it's powerful.

If you take one thing from this guide, let it be this: most IB subjects have an IA or an internal component, and the students who do best are the ones who stop treating it as separate from exam prep.

RevisionDojo is designed for that reality: examiner-written Study Notes, spaced repetition Flashcards, a targeted Questionbank, supportive AI Chat, rubric-based Grading tools, Mock Exams, Predicted Papers, a Coursework Library, and Tutors when you need a human voice. Use the platform to make your IA clearer, your revision more focused, and your exam weeks less chaotic.
