How MYP Mathematics Is Assessed: Revision Notes

Condensed for quick recall of how the subject is assessed. For the full subject overview, use the IB MYP Mathematics subject overview.

No SL/HL split — four criteria instead

Criterion	Focus
A — Knowing and understanding	Recall and applying known procedures
B — Investigating patterns	Identifying and generalising patterns
C — Communicating	Using correct mathematical language and representation
D — Applying mathematics in real-life contexts	Applying maths to real-world problems

Each scored on an 8-point scale (1-8), equally weighted; a student’s level in each criterion is matched to the best-fit grade descriptor, not totalled exam marks.

Why there’s no SL/HL split at MYP level

Like every MYP subject, Mathematics does not distinguish Standard and Higher Level in the DP sense – differentiation instead happens through the standard-vs-extended pathway choice and through the depth a student demonstrates within each criterion’s band descriptors, rather than through parallel courses assessed at different overall demand.

Standard vs. Extended

Both assessed against the same four criteria — extended mathematics adds topics and depth on top of the standard curriculum, preparing students for DP-level mathematics.

If your school offers MYP eAssessment (year 5)

A 2-hour on-screen exam, three tasks mapping to the same four criteria: knowing and understanding, investigating patterns, and applying mathematics in real-life contexts.

The four criteria in more depth

Each criterion is assessed against level descriptors typically organised in four bands (for example 1-2, 3-4, 5-6, 7-8): criterion A rewards accurate recall and correct application of known procedures to increasingly unfamiliar problems; criterion B rewards the ability to identify a pattern, express it in general terms (often algebraically), and justify why the generalisation holds; criterion C rewards clear, logically sequenced working using correct mathematical notation and appropriate forms of representation (tables, graphs, diagrams); criterion D rewards identifying a genuine real-life context, selecting appropriate mathematics to model it, and communicating a solution with an accurate real-world interpretation, not just a correct number. A common weakness across all four criteria is arriving at a correct final answer without showing the reasoning that earns marks under criteria B and C specifically – an unexplained correct answer scores well under criterion A but poorly under the criteria that reward process and communication.

Why standard and extended aren’t simply “easier” and “harder”

Both pathways are assessed against the identical four criteria and level descriptors – a student on the standard pathway who demonstrates deep understanding within the standard curriculum’s scope can achieve the same top band (7-8) on any criterion as an extended-pathway student, since the descriptors reward depth and quality of mathematical thinking, not the sheer quantity of content covered. Extended mathematics adds further topics (typically more advanced algebra, trigonometry, and introductory calculus concepts) precisely because these are the topics DP-level mathematics courses assume as a starting point, so the pathway choice is really about preparation for what comes next, not a judgement about a student’s current ability.

The eAssessment structure in more depth

Where a school opts into eAssessment (available at MYP year 5), the on-screen exam is built to sample across the same four criteria used in ongoing classroom assessment throughout the two-year cycle, rather than introducing a separate assessment model – this consistency means strong performance in classroom-based tasks against the criteria is the most reliable preparation for the eAssessment itself, more so than last-minute exam-specific revision. Because “investigating patterns” (criterion B) requires justifying a generalisation, not just spotting it, timed practice under exam conditions is worth including in revision even for students confident in pattern recognition from classwork.

How MYP Mathematics connects forward to DP Mathematics

Both DP mathematics courses (Analysis and Approaches, and Applications and Interpretation) assume the algebraic fluency, pattern-generalisation skill, and real-world modelling experience built through MYP Mathematics’s four criteria, particularly extended mathematics’s additional content. Students who have consistently practised justifying generalisations (criterion B) and communicating solutions with correct notation (criterion C) throughout MYP typically find the transition to DP-level proof and modelling expectations considerably smoother than those who have focused revision narrowly on getting correct final answers.

Exam traps

• Treating “investigating patterns” (Criterion B) as the same skill as “knowing and understanding” (Criterion A) — pattern generalisation is a distinct, separately assessed skill.
• Weak mathematical communication (Criterion C) — using correct notation and clear working matters independently of getting the right answer.
• Not connecting classwork to real-life applications, since Criterion D specifically rewards this.

Self-test

1. Name the four MYP Mathematics criteria.
2. What’s the difference between standard and extended mathematics?
3. How is a student’s achievement level determined for each criterion?
4. What does Criterion D specifically assess?
5. Why can a standard-pathway student achieve the same top band as an extended-pathway student?
6. Why is timed practice worth including in revision even for a student confident at spotting patterns?

Answers: 1. Knowing and understanding; Investigating patterns; Communicating; Applying mathematics in real-life contexts. 2. Both cover the same four criteria, but extended mathematics adds further topics and greater depth, preparing students for DP-level maths. 3. By matching their work against the grade descriptor that best fits, not by totalling exam marks. 4. Applying mathematics in real-life contexts. 5. Because the level descriptors reward depth and quality of mathematical thinking within a pathway’s scope, not the sheer quantity of content covered — both pathways are assessed against the identical criteria. 6. Because criterion B rewards justifying a generalisation, not just spotting it, and timed conditions test whether that justification can be produced under exam-style time pressure, not only during untimed classwork.
