Who marks MYP Standard Mathematics depends on the assessment. Your mathematics teacher marks normal classwork, investigations, tests, and usually mock examinations. If your school registers you for the official MYP Mathematics on-screen examination, trained IB examiners mark your responses externally.
This distinction matters because the MYP combines school-based assessment with optional external eAssessment. Schools may use different internal procedures, so students should confirm the status of an assessment with their teacher or MYP coordinator.
Who marks each type of MYP Mathematics assessment?
The phrase MYP Standard Mathematics is commonly used to distinguish a standard course from Extended Mathematics. On the IB's public eAssessment pages, however, the on-screen subjects are formally listed as Mathematics and Extended mathematics.
| Assessment | Who normally marks it? | Official status |
|---|---|---|
| Class test or unit task | Mathematics teacher | Used for school assessment and reporting |
| Mathematical investigation | Mathematics teacher | Assessed against relevant MYP criteria |
| School mock examination | Usually a teacher at the school | Practice rather than an official IB result |
| Official Mathematics on-screen examination | Trained IB examiners | Externally assessed IB component |
| Personal project or ePortfolio subject | Teacher, followed by IB moderation | Uses a different process from Mathematics |
The IB explains that ordinary MYP classroom assessment is created and marked by teachers. Teachers make judgments using published subject-group criteria, not simply percentages or totals of correct answers.
Who marks the official Mathematics eAssessment?
The official MYP Mathematics on-screen examination is externally marked by trained IB examiners. It is not marked by the candidate's classroom teacher, and each candidate's submitted responses are assessed.
The IB's MYP eAssessment Q&A document states that Mathematics and Extended Mathematics on-screen assessments are individually marked. A teacher may predict a student's performance, but that prediction is not the official examiner-awarded result.
External marking is not moderation
Students sometimes use external marking and moderation as if they describe the same process. They are different:
- External marking means an IB-appointed examiner directly marks a candidate's examination responses.
- Moderation begins with marks awarded by teachers. The IB reviews selected work to decide whether the school's marking standard should be accepted or adjusted.
Mathematics uses an on-screen examination, so it is externally marked. The personal project and specified ePortfolio subjects instead involve teacher marking followed by external moderation.
What happens on MYP Mathematics exam day?
School staff supervise the official session, but they do not award the examination marks. The school handles candidate identification, invigilation, approved access arrangements, device preparation, and secure submission of response files.
The usual sequence is straightforward: the school prepares the room and devices, invigilators admit and brief candidates, students complete the on-screen assessment, and the response files are securely submitted. IB-appointed examiners then mark the work, and results are issued through the school.
Arrival times, room arrangements, and device allocation can vary. Students should therefore follow their own school's instructions rather than procedures described by candidates elsewhere.
How classroom Mathematics work is assessed
School-based MYP Mathematics uses four assessment criteria:
- Criterion A: Knowing and understanding
- Criterion B: Investigating patterns
- Criterion C: Communicating
- Criterion D: Applying mathematics in real-life contexts
These criteria assess different aspects of mathematical performance. A correct answer may demonstrate knowledge, while an investigation can also require a general rule, evidence, justification, and accurate notation. An application task may require students to interpret whether a result is reasonable in context.
The official MYP Mathematics subject brief outlines these objectives. Teachers use the relevant descriptors and task requirements to determine the achievement level that best represents the work.
Common misunderstandings about marking
Not every Year 5 Mathematics assessment is sent to the IB. Most classroom tests and assignments remain internally assessed, even when they resemble eAssessment questions. Only registered official components enter the IB's external assessment process.
A mock is also not automatically an IB examination. It is normally school-administered practice and marked locally. Teachers cannot directly replace an external examiner's mark, although the MYP coordinator can explain any applicable results-enquiry process after results are released.
Practical advice for students and coordinators
Whenever the status of an assessment is unclear, ask: Is this a classroom assessment, a mock, or the registered IB on-screen examination? The answer normally establishes who marks it and how the result will be used.
Students can use MYP Standard Mathematics revision notes to review methods, followed by the MYP Standard Mathematics Questionbank for targeted practice. The guide to how MYP Mathematics is assessed explains how responses connect to the four criteria.
Schools should clearly separate teacher assessment, school administration, and external examiner marking. An MYP eAssessment 30-day study plan can also help students rehearse timing and digital navigation.
Conclusion
Teachers mark ordinary MYP Standard Mathematics assessments and usually mark school mocks. Trained IB examiners mark each candidate's official Mathematics on-screen examination externally, while the school manages registration and examination administration.
