The MYP Standard Mathematics eAssessment structure consists of one externally marked, on-screen examination lasting two hours. It is worth 100 marks and contains three overarching tasks: knowing and understanding, investigating patterns, and applying mathematics in real-life contexts. Across these tasks, four equally weighted assessment criteria contribute 25 marks each.
Success therefore requires more than correct numerical answers. Students must also investigate, justify, communicate, model, interpret, and evaluate mathematical results. It is also important to distinguish the external examination score from the classroom assessment total out of 32.
MYP Standard Mathematics eAssessment at a glance
The current official IB Mathematics subject brief identifies number, algebra, geometry and trigonometry, and statistics and probability as the main branches of MYP Mathematics.
| Feature | Current structure |
|---|---|
| Assessment type | Externally marked on-screen examination |
| Duration | 2 hours |
| Total marks | 100 |
| Overarching tasks | 3 |
| Criteria assessed | A, B, C and D |
| Weighting per criterion | 25 marks, or 25% |
| Final subject grade | 1 to 7 |
| Grade boundaries | Set for each examination session |
The examination is taken in MYP year 5 by registered eAssessment candidates. It is not a conventional paper divided into calculator and non-calculator sections. Students work with stimulus material, digital tools, and linked questions within the on-screen environment.
How the three mathematics tasks are organized
Each task normally carries approximately 31 to 35 marks, with all three combining to produce 100 marks.
| Task | Main criteria | What students do |
|---|---|---|
| Knowing and understanding | A and C | Select methods, solve problems, and communicate working |
| Investigating patterns | B and C | Explore examples, identify patterns, formulate rules, and justify conclusions |
| Applying mathematics in real-life contexts | C and D | Model situations, interpret results, and evaluate validity |
These are broad tasks rather than isolated topic sections. A real-life task, for example, might combine algebraic functions, graphical interpretation, measurement, units, and statistics.
Task 1: Knowing and understanding
This task primarily assesses Criterion A. Students select appropriate mathematics and apply it in familiar and unfamiliar situations. Questions may involve direct procedures, multi-step calculations, interpreting representations, or connecting several topics.
Criterion C is also assessed, so an unexplained calculator result may not receive every available mark. Students should show substitutions, equations, transformations, units, and essential reasoning clearly enough for an examiner to follow the method.
Task 2: Investigating patterns
This task primarily assesses Criterion B. Students may generate results, identify a relationship, express it as a general rule, and verify or justify that rule.
For the sequence 5, 8, 11, 14, recognizing a common difference of 3 is only an initial observation. A complete investigation might establish the general term a(n) = 3n + 2, verify it using known terms, and explain why it applies generally. Testing one value is not necessarily a sufficient justification.
Task 3: Applying mathematics in real-life contexts
This task primarily assesses Criterion D. Students translate a situation into mathematics, apply a model, obtain a result, interpret it in context, and consider whether it is reasonable.
If a model predicts a water depth of 4.638 metres, a strong response does not stop at the number. It gives an appropriately rounded value with units, explains its contextual meaning, and considers assumptions, limitations, or the model's valid domain.
How the four criteria are weighted
All four mathematics criteria contribute equally:
- Criterion A: Knowing and understanding -- 25 marks. Select and apply suitable mathematics accurately.
- Criterion B: Investigating patterns -- 25 marks. Identify relationships, formulate general rules, and verify or justify them.
- Criterion C: Communicating -- 25 marks. Use correct notation, mathematical language, representations, and logical reasoning.
- Criterion D: Applying mathematics in real-life contexts -- 25 marks. Model situations, interpret conclusions, and evaluate validity.
Criterion C is assessed across all three tasks, not in one separate section. Communication marks are therefore available throughout the examination. The MYP Mathematics criteria guide explains what each criterion requires in greater detail.
How raw marks become an MYP grade
Examiners award marks using the examination markscheme. The criterion marks combine into a raw total out of 100, which is converted into a final grade from 1 to 7 using the boundaries for that examination session.
This differs from school-based MYP assessment. Teachers commonly award achievement levels from 0 to 8 for each criterion, producing a total out of 32. The external eAssessment uses the same four conceptual criteria but reports a raw examination mark out of 100 before grade-boundary conversion.
| Stage | Illustrative result |
|---|---|
| Criterion A | 18/25 |
| Criterion B | 16/25 |
| Criterion C | 19/25 |
| Criterion D | 15/25 |
| Raw examination mark | 68/100 |
There is no permanent rule stating that a particular percentage always earns a grade 7. The IB sets session-specific grade boundaries because examination demand can vary. Its published assessment principles and practices describes a process involving grade descriptors, candidate work, expert judgement, and statistical evidence.
Previous boundaries can support rough mock-exam estimates, but they cannot guarantee a future grade. Coordinators should use the official boundary document for the correct subject and session.
Standard Mathematics versus Extended Mathematics
Standard Mathematics develops a sound knowledge of fundamental mathematical principles. Extended Mathematics includes additional topics and skills, giving the course greater breadth and depth.
Both examinations follow the same broad model: one on-screen examination, three tasks, four equally weighted criteria, and grades from 1 to 7. However, they are separate courses with different questions and potentially different boundaries. The Standard and Extended Mathematics comparison clarifies the differences in demand.
Practical preparation for the examination
Revision should cover every assessment criterion rather than focusing only on procedural calculations.
- For Criterion A, practise choosing methods without being told which formula to use.
- For Criterion B, complete investigations that progress from examples to a general rule and justification.
- For Criterion C, use correct notation, labelled graphs, units, and connected reasoning.
- For Criterion D, interpret answers and discuss accuracy, assumptions, limitations, and validity.
Timed practice should reflect the complete two-hour format. With 120 minutes for 100 marks, students have an overall average of approximately 1.2 minutes per mark, although longer investigations and modelling questions may require more reading and planning. Displayed marks should guide the amount of working and explanation provided.
Students can rebuild topic knowledge using MYP Standard Mathematics revision notes before applying it through the MYP Standard Mathematics Questionbank. Full timed practice should include checking notation, units, rounding, unanswered parts, and contextual conclusions.
Common structural mistakes
A common mistake is treating the examination as a collection of isolated calculations. Correct answers matter, but substantial marks reward investigation, communication, modelling, and evaluation.
Students also lose marks by stating a general rule without justification, reporting decimals without units, or writing vague evaluations such as “the model is accurate.” A useful evaluation refers to evidence, assumptions, limitations, rounding, or domain restrictions. Another frequent error is treating the classroom total out of 32 as though it were the external raw score out of 100.
Conclusion
The MYP Standard Mathematics eAssessment structure is a two-hour, 100-mark on-screen examination organized around three tasks and four equally weighted criteria. Criterion A emphasizes mathematical knowledge, Criterion B focuses on investigation, Criterion D assesses real-life application, and Criterion C operates throughout the examination.
Raw marks are converted into grades using session-specific boundaries rather than a permanent percentage table. Effective preparation must combine accuracy with clear reasoning, justification, modelling, and evaluation. RevisionDojo's Study Notes and Questionbank can support this balanced preparation under timed conditions.
