IB Math AA: Coordinator guide for 2026 + 2029 syllabus outlook

IB Math AA is short for Mathematics: Analysis and Approaches. It is the more theoretical of the two DP mathematics courses, built around calculus, algebraic reasoning, and proof. In 2026, schools are teaching the 2021 syllabus, and that syllabus stays active right through to the November 2028 session. A revised syllabus is in development. First teaching is August 2027 and first assessment is May 2029. So you have one overlap year. This guide walks DP coordinators through where the course sits today, what the transition window actually looks like, and what to put in place before the new guide drops.

TL;DR

The current state of IB Math AA in 2026

The 2021 Math AA syllabus stays active through November 2028. So every teaching plan, mock paper, and IA cycle this year and next maps to that guide.

The course splits into Standard Level and Higher Level. Both sit across five topics: Number and Algebra, Functions, Geometry and Trigonometry, Statistics and Probability, and Calculus. HL adds Paper 3. That paper is one hour long and built around two extended-response problem-solving questions. SL and HL both carry an internal assessment (the mathematical exploration), worth 20 per cent of the final grade.

What's worth noting in 2026 is what hasn't changed. The five topic areas, the assessment weightings, the IA criteria, and the calculator policy on each paper. All the same documents your department has been working with since first teaching in August 2021. You don't need to redesign schemes of work this year. You do need to start preparing the team for what's coming.

One coordinator I spoke with this term thought her Y2 cohort had a May 2028 final session. She had been planning the department wind-down around that date. They actually have a full extra session in November 2028, which means another year of the legacy IA cycle, another year of legacy mocks, and a different leadership-transition conversation than she was preparing for. Check yours.

The 2027/2029 syllabus transition: what we know and what we don't

New Math AA syllabus: first teaching August 2027, first assessment May 2029. The published subject guide hasn't dropped yet, so detailed planning has to wait.

The IB has confirmed Math AA sits inside the current multi-year curriculum review. What's been signalled, across IB communications and adjacent subject updates, is that the new course will move in the same direction the wider IB is moving. More conceptual understanding, tighter alignment with on-screen assessment, and a closer link between the IA and the externally assessed content.

What we don't know yet:

• The final topic list and any topics being removed

• Confirmed assessment structure (paper count, durations, weightings)

• The exact format of the digital assessment when it lands for Math AA

• Whether the IA brief or marking criteria will change

Resist the urge to redesign anything around speculation. The practical move right now is to ring-fence a department session in the 2026/27 academic year for new-syllabus orientation, ready to run once the draft guide is published.

Paper 1 non-calculator workflow: what changes in a digital exam

Paper 1 stays non-calculator under the current syllabus. Any digital version of the exam has to preserve clean algebraic working, which is where on-screen assessment design matters most.

Paper 1 is where students have to show technique. No GDC. No Desmos. No online graphing. Marks are won on algebraic manipulation, calculus by hand, and proof structure at HL.

In a paper-based exam, students write working in the answer booklet and method marks fall out naturally. In a digital exam, that workflow has to be rebuilt. Students need a way to show algebraic steps on screen. Options include a maths input editor, a stylus-based working area, or a scanned working sheet uploaded with the response. Each model has trade-offs. Whichever route the IB takes for Math AA, your department should be running mocks in that format at least 18 months before the live exam.

The risk if you don't: students who can solve the problem on paper but lose method marks because they can't show their working clearly on screen.

Papers 2 and 3: GDC-required workflow in a digital environment

Papers 2 and 3 require a GDC. A digital version of these papers has to handle GDC use alongside the on-screen interface, either through an embedded calculator or a permitted physical device.

Paper 2 covers the full syllabus at SL and HL with a GDC available throughout. Paper 3 at HL is two extended-response problem-solving questions, also GDC-required. Students need to be fluent in:

• Solving equations numerically when an analytical solution is messy

• Statistical functions for the probability and statistics topic

• Calculus functions: numerical integration, derivative at a point, intersection points

• Sketching and interpreting graphs to support written reasoning

A digital exam doesn't remove the GDC. It changes how the GDC sits in the student's workflow. If the on-screen exam is delivered on the same device the student normally uses, the GDC has to either be a physical device next to them or an embedded equivalent. Both options have implications for invigilation, security, and the rubric for showing GDC working.

This is the conversation to start having with your maths team now. How do they want students working in a hybrid screen and GDC environment, and what does that mean for the kit on the desk?

Paper 3, the extended problem-solving structure where students get stuck

Paper 3 at HL is built around two long, scaffolded problems. Students who lose grip on the early parts often can't recover marks in the later parts. So the failure mode is structural, not topical.

Each Paper 3 question typically runs across multiple parts (a), (b), (c)… with later parts building on earlier results. The IB designs these to test sustained reasoning: pattern recognition, generalisation, and proof.

The practical issue is recovery. If a student gets stuck on part (b), and part (c) depends on the result from (b), they can lose access to a chain of follow-on marks. We don't have published topic-level mark-loss data from the IB on Paper 3 specifically, so any precise percentage you've seen quoted should be treated cautiously. What we do see in coordinator conversations is a consistent pattern. Students who haven't practised long-form problem-solving in advance under-perform on Paper 3 relative to their Paper 1 and Paper 2 performance.

Practical countermeasures:

• Build a Paper 3-style problem into every internal HL mock from Year 1 onwards

• Teach "follow-through" technique explicitly. Using a sensible value for an unknown result lets later parts still score

• Drill the structure, not just the topics

The IA mathematical exploration: brainstorm early, finalise later

The internal assessment is worth 20 per cent of the final grade and is marked against five criteria: presentation, communication, personal engagement, reflection, and use of mathematics. The biggest coordinator-level mistake right now is letting students lock in their topic too early.

Under the 2021 guide, the exploration is a 12 to 20 page individual investigation on a maths topic the student chooses. Drafting runs across the second half of Year 1 and into Year 2. The five criteria total 20 marks.

Here's the correction worth flagging. The May 2025 HL Subject Report told teachers directly to avoid early finalisation of topics. The examiners' wording: finalising the exploration too early in the course often prevents students from accessing more sophisticated mathematical concepts introduced later. Translated for the classroom, a strong HL student who locks in their topic in October of Year 1 hasn't yet met integration by parts, polar coordinates, or the calculus content that would lift their exploration into the top band. They've committed to the maths they already know.

We saw this exact pattern with a Y1 student last cycle. She picked a probability topic in October. A strong choice on paper. By March, her teacher had started Markov chains. By May, she'd hit the calculus methods that would have transformed her analysis. But she'd been refining her introduction and methodology for six months. The opportunity cost was a Criterion E ceiling she couldn't lift.

Two coordinator moves that hold for 2026:

1. Start brainstorming early. Run idea-generation sessions in late Year 1, share past explorations, get students reading and exploring topic spaces. Early thinking is good.

2. Don't force lock-in. Build flexibility into your timeline so students can pivot or sharpen their topic once they've met the Year 2 content. A formal topic confirmation in late Year 1, not early Year 1, gives them room to use the maths they're still learning.

The other rule that holds: personal engagement is the differentiator at the top end. Generic explorations on "the maths of basketball" rarely score full marks. Explorations rooted in something the student genuinely cares about routinely do.

For the 2029 syllabus, expect the IA structure to be reviewed alongside everything else. No signal yet that the IA will be removed from Math AA, but the criteria, weighting, or word count could shift. Plan for the 2021 IA right through November 2028, then re-orient.

How AssessPrep handles the Math AA workflow

AssessPrep's IB question bank holds 1,700+ Math AA questions tagged by topic, subtopic, paper, and calculator policy, with a GDC-aware delivery layer and AI-supported method-mark grading. Visit the Math AA question bank landing page for the full breakdown.

The Math AA workflow inside AssessPrep is built around the three-paper structure. Paper 1 tests are delivered with the GDC tool disabled at the platform level. Paper 2 and Paper 3 tests are delivered with the GDC permitted, either as the on-screen embedded version or as a physical device beside the student. Lockdown mode is available for all three.

For grading, the platform supports method-mark workflows. Teachers see the student's working alongside the markscheme and can award marks for valid alternative methods, partial credit, and follow-through. AI-assisted grading flags likely-correct responses for fast confirmation while keeping the final judgement with the teacher. Across the network of 800+ partner schools in 85+ countries, that combination is what saves DP maths teams the most time at mock season.

For HL Paper 3-style questions, coordinators can build extended problems with multi-part dependencies, then track which sub-parts students are getting stuck on across the cohort.

AA vs AI, the coordinator decision point

The choice between Math AA and Math AI should be driven by the degree pathway the student is heading toward, not perceived course prestige. And it's a coordinator-led conversation, not a parent-led one.

Math AA is the natural fit for students heading into engineering, physics, theoretical mathematics, computer science, and most quantitative economics programmes. The course teaches the algebraic and calculus technique those degrees assume on day one. Math AI is the natural fit for students heading into business, social sciences, design, biology, and applied fields where statistics and modelling matter more than proof.

The conversation that breaks down in many schools: students choose AA because they or their parents think it "looks better" to universities. Universities specify which course they require. And an HL 4 in AI almost always outperforms an HL 4 in AA for an admissions case where AI was the more appropriate course.

Coordinator move: build a structured Year 11 placement conversation, share the IB's own subject brief for both courses with families, and reference real university requirement data from the previous three years of your school's alumni.

Preparing your DP Math team for the 2027/2029 syllabus

The window between the new subject guide being published and first teaching in August 2027 is short. Most departments will get one full academic year of orientation. So 2026/27 is the year to set up the structure.

Practical steps for the 2026/27 cycle:

1. Identify a Math AA lead inside the department whose remit includes new-syllabus orientation

2. Block out three department meetings across the year specifically for the new guide once published

3. Run one cross-school session with peer DP coordinators in your region to compare interpretations

4. Audit your current teaching resources for what carries over and what doesn't

5. Plan the first new-syllabus mock for late 2028, roughly one term before first live assessment

What not to do in 2026/27: rewrite schemes of work, replace textbooks, or change IA timing for current students. None of those decisions should be driven by a syllabus that hasn't been published yet.

Action checklist for Math AA coordinators

A short list for the next 12 months:

• Run a full Paper 3-style mock for HL students this term, then again before final mocks

• Audit your GDC fleet. Confirm all students on the current SL+HL cohort have a model on the IB permitted list

• Make Paper 1 (non-calculator) mocks digital at least once this year, even if the live exam is still paper

• Move IA topic confirmation later in Year 1. Keep brainstorming early, but stop forcing early lock-in

• Schedule a department session for the new subject guide in the 2026/27 calendar. Placeholder slot, even before the guide drops

• Review your AA vs AI placement process for the incoming Year 11 cohort

• Check your question bank coverage for topic-level practice. Explore the Math AA question bank for ready-made sets

Conclusion / Key Takeaways

• The 2021 Math AA syllabus is in force through November 2028. No structural changes needed to current teaching.

• The 2029 syllabus will land with first teaching August 2027. The 2026/27 year is for setting up department orientation, not for redesigning anything.

• Paper 1 (non-calculator) and Papers 2/3 (GDC-required) each need their own digital-exam workflow practised now.

• Paper 3 failure modes are structural. Students who can't recover from getting stuck on early parts lose chains of marks later.

• IA topic selection: brainstorm early, finalise later. Per the May 2025 HL Subject Report, premature lock-in blocks access to the Year 2 maths students need to hit the top band.

• The AA vs AI decision belongs to the coordinator and the degree pathway, not to perceived prestige.
