The MYP Extended Mathematics eAssessment is marked externally by IB-appointed examiners, not by the student’s mathematics teacher. Examiners apply task-specific markschemes to the candidate’s digital responses, awarding raw marks for the mathematical evidence shown. The IB then converts the examination total into a final subject grade from 1 to 7 using boundaries established for that examination session.
This is an on-screen examination, not an ePortfolio moderated from teacher-awarded levels. Classroom assessments may help predict performance, but the official result depends on the work submitted in the examination.
The marking process
The process has five main stages:
- The student completes the examination on a computer at school.
- The examination software records the responses.
- The school securely returns the response files under IB procedures.
- Trained examiners award marks using authorized markschemes.
- The IB applies session-specific grade boundaries and reports a 1--7 grade.
The IB overview of MYP assessment confirms that on-screen examinations are externally marked. Mathematics and Extended Mathematics examinations are individually marked, unlike components where teachers award marks that are subsequently moderated.
How the examination tasks are assessed
The official MYP Mathematics subject brief organizes the examination around three broad tasks. Each produces evidence for specified criteria, while Criterion C: Communicating is assessed throughout.
| Examination task | Main criteria | Evidence examiners reward |
|---|---|---|
| Knowing and understanding | A and C | Knowledge, suitable methods, accurate calculations and clear working |
| Investigating patterns | B and C | Patterns, general rules, testing, justification and representation |
| Applying mathematics in real-life contexts | C and D | Modelling, application, interpretation, conclusions and evaluation |
The subject brief indicates that each task is normally worth approximately 31--35 marks. Criterion C contributes 25 marks across the three tasks, helping provide balanced representation of the four mathematics criteria.
Extended Mathematics uses the same broad criteria as Mathematics but may demand more advanced content, depth and reasoning. Students can review concepts through Extended Mathematics Study Notes and then practise applying them in the Extended Mathematics Questionbank.
How examiners award raw marks
Examiners do not assign one overall criterion level to an entire response. They use a task-specific markscheme that awards marks for particular evidence, which may include:
- selecting and applying a suitable method
- calculating accurately and showing logical steps
- identifying, testing and justifying a general rule
- using appropriate notation, graphs, tables or diagrams
- interpreting an answer in context
- evaluating whether a model or conclusion is reasonable
A correct final number may be insufficient when the command term requires students to show, justify, verify, interpret or evaluate. A valid method may earn some credit despite a later arithmetic error, but only when the necessary evidence is visible and the markscheme allows it.
For example, writing only gives the examiner little evidence. Showing the equation, rearrangement, solution and contextual conclusion allows method, accuracy and communication to be assessed separately.
Raw marks and final grades
Students often confuse three different ideas:
| Term | Meaning |
|---|---|
| Raw mark | Points awarded for evidence in individual responses |
| Criterion representation | How Criteria A--D shape the examination design |
| Final grade | The official subject result reported from 1 to 7 |
Students should not convert the examination using the classroom total out of 32. Classroom assessment commonly combines four criterion achievement levels out of 8, whereas the external examination begins with task-specific raw marks.
Grade boundaries can differ between sessions because the IB considers the demand of each examination before confirming standards. A percentage associated with a past paper therefore cannot guarantee the same grade later. The MYP passing criteria also concern the full certificate rather than the boundary for one subject.
Examination logistics and technical issues
The assessment is completed under supervision using approved on-screen examination software. Schools manage devices, rooms, candidate instructions and the secure return of responses under IB requirements.
Local details can vary, so students should confirm arrival times, permitted materials, rough-work procedures, device familiarization and any approved inclusive access arrangements with their coordinator. If a technical problem occurs, alert the invigilator immediately rather than attempting an independent repair. The public IB on-screen examinations page explains the assessment format, while coordinators receive session-specific instructions separately.
How to make responses markable
Show enough reasoning for an examiner to follow the solution. Use correct notation, label graphs and axes, include relevant units and state conclusions that answer the question directly.
In pattern investigations, give a general rule, test it and justify it when requested. In modelling questions, interpret the result and discuss assumptions, limitations or validity where required. Timed practice also matters because incomplete reasoning cannot receive marks; the MYP eAssessment timing guide and 30-day study plan can support structured preparation.
Conclusion
MYP Extended Mathematics eAssessments are externally and individually marked using task-specific markschemes. Students earn marks by making their methods, reasoning, communication and conclusions visible, after which the IB awards a grade from 1 to 7. RevisionDojo’s Study Notes, Questionbank and Jojo AI can support focused practice alongside current instructions from the school.
