Four criteria (A–D) per subject group
Every MYP subject group uses four criteria (A–D) that are subject-specific but share a common 0–8 scale. Teachers design tasks against these criteria and award achievement levels.
IB assessment combines internal work marked by teachers and external exams marked by IB examiners. The balance differs across the Diploma Programme, Career-related Programme and Middle Years Programme. This guide maps the components, criteria, moderation process, grading scale and typical milestones so students and families can plan with clarity.
Each DP subject includes external examination papers and at least one internal assessment component. The weighting varies by subject group. Theory of Knowledge is assessed through an exhibition and an essay. The Extended Essay is an independent research paper marked externally. CAS requires a portfolio of experiences and reflections but is not graded; it must be completed for the diploma.

Subject tutors help students align internal assessment drafts with markschemes, practise exam technique for external papers, and structure the Extended Essay, TOK essay and Reflective Project. For MYP, tutors support criterion-focused revision, Personal Project planning and eAssessment familiarisation. Revision planning uses the school's internal calendar and the IB upload and exam windows to space workload realistically.
Internal assessment is marked by school teachers using IB markschemes and then moderated by the IB. External assessment includes final exams and uploaded components marked directly by IB examiners.
Each DP subject receives a 1–7 grade based on the weighted combination of examination papers and internal assessment components. The TOK/EE matrix adds core points toward the diploma maximum.
