IB Middle Years Programme Mathematics

criterion-referenced

Source: official International Baccalaureate specification, verified 2026-09-04. Read directly from the public IB MYP Mathematics subject brief ("From 2020, first assessment 2022" -- the one MYP subject brief among the five modeled in this batch that states an explicit first-assessment year rather than only a framework currency date, used verbatim here). All four criteria equally weighted (25% each), 8-level achievement scale (marks=8 = the maximum achievable level, not an exam mark total), teacher-assessed across the year against published IB rubrics and externally moderated by IB sampling, no fixed sitting duration (durationMinutes: null). Same modeling rationale as the MYP Sciences record above: the public subject brief is sufficient here because MYP genuinely has no fixed-marks exam-paper structure for most students, unlike DP. Optional MYP eAssessment (on-screen exam, for MYP Certificate/course-results seekers only, not modeled as this record's components) comprises three tasks per the same brief: Knowing and understanding + Communicating (criteria A and C), Investigating patterns + Communicating (criteria B and C), and Applying mathematics in real-life contexts + Communicating (criteria C and D), each 31-35 marks, with criterion C assessed across all three tasks to a combined 25 marks -- cited for completeness only.
