EEFrom May 2027
Revised Extended Essay
The revised EE model applies from first assessment in May 2027. Students must use the criteria, reflection requirements and subject guidance for the correct version.
Official IB update
IB Mathematics · Requirements and criteria
Use the requirements for the correct assessment session.
General guidance and version-specific assessment information are kept separate so outdated criteria are not confused with current requirements.
Version control
The assessment session determines which rules apply.
Curricula, assessment criteria, forms and school procedures may be revised. Every summary therefore needs a visible statement of validity.
IAFrom May 2029
Updated Mathematics courses
The revised Mathematics AA and AI courses are first assessed in May 2029. The mathematical exploration remains, but its criteria change.
Internal school deadlines may be earlier.The IB communicates submission dates to schools. Schools commonly set internal milestones and final deadlines that are decisive for personal planning.
Mathematics IA through assessment 2028
The current exploration uses five criteria.
This short overview is for orientation. The current subject guide for the student's assessment session contains the full descriptors.
A: Presentation
Coherent, logically organised and concise structure.
B: Mathematical communication
Correct notation, terminology, diagrams, units and definitions.
C: Personal engagement
Independent choices and an exploration visibly shaped by the student.
D: Reflection
Evaluation of results, methods, assumptions, limitations and improvements.
E: Use of mathematics
Relevant, correct and appropriately sophisticated mathematics.
Mathematics IA from assessment 2029
Four criteria follow the mathematical inquiry process.
SL and HL use the same IA criteria in the revised model. Expectations for the mathematics itself still depend on the course and level.
A: Problem specification
Define the problem in context and the desired outcomes.
B: Abstraction
Justify assumptions, methods, tools and mathematical form.
C: Computation
Carry out calculations and mathematical communication correctly.
D: Interpretation
Interpret results, evaluate outcomes and refine the investigation.
Source hierarchy
What takes priority when information conflicts.
- current official subject guide or EE guide
- official assessment procedures and IB updates
- instructions from the school and programme coordinator
- PreLearning summaries for orientation
- external blogs, videos or example sites only as supplementary material
Record the assessment session before planning details.
This allows criteria, example work and guidance to be matched to the correct curriculum version from the start.
