Is the MYP Standard Mathematics eAssessment marked by my teacher?

No. The official on-screen examination is marked externally by trained IB examiners rather than by the student’s classroom teacher. Teachers still use the MYP mathematics criteria to assess schoolwork and prepare students during the course. However, they do not assign the official raw mark or final 1-to-7 eAssessment grade. This distinction is important because mathematics examinations are individually marked, while ePortfolios and the personal project use moderation processes. A teacher may review specimen responses with students, but cannot alter the official examination result.

Can I receive marks if my final answer is wrong?

Yes, some questions can award partial credit for a valid method, correct intermediate work, or relevant mathematical reasoning. The available credit depends on the question and its markscheme, so it is not guaranteed in every case. Showing a formula, substitution, algebraic step, or appropriate diagram gives the examiner evidence to assess. A final-answer-only response provides much less evidence if that answer is incorrect. Students should therefore show concise working even when using the on-screen calculator.

Does mathematical communication affect every examination task?

Yes. Criterion C: Communicating is assessed across all three mathematics tasks rather than through one separate section. Communication includes correct notation, logical organization, labelled representations, defined variables, units, and explanations suited to the question. A student can therefore lose access to marks by giving an unexplained rule or an ambiguous graph even when the underlying idea is promising. This does not mean every calculation needs a long written paragraph. The aim is to provide enough precise mathematical evidence for the reasoning to be followed.

Is the MYP Standard Mathematics examination marked out of 8 for each criterion?

Not directly in the same way as a classroom assessment. During the course, teachers commonly judge work against criterion achievement levels from 1 to 8. In the on-screen examination, individual questions instead carry raw marks linked to the relevant criteria and question-specific markscheme. Those raw marks are combined before the IB awards a final subject grade from 1 to 7. Students should therefore practise responding to the demands of each question rather than trying to assign themselves four classroom criterion levels after the examination.

What happens during MYP Standard Mathematics exam day?

Students sit a two-hour on-screen examination on a computer prepared or approved by their school. The examination software can provide response fields and mathematical tools, including an on-screen calculator and graphing functions. Schools follow IB security and invigilation requirements, but practical details such as arrival time, seating, devices, and local instructions can vary. Students should follow their coordinator’s current instructions rather than assumptions based on another school or an older session. Before exam day, they should practise with the official familiarization package so that navigation does not consume working time.

Are the grade boundaries fixed for MYP Standard Mathematics?

Students should not assume that one fixed classroom percentage will always produce the same IB grade. The IB uses a criterion-related grade-award process based on demonstrated standards, with the completed examination reported on the 1-to-7 scale. Raw marks are therefore not interpreted in exactly the same way as a teacher-created percentage test. Coordinators receive the official results and should consult session-specific IB documentation when explaining outcomes. For preparation, it is more useful to strengthen all four criteria than to rely on an unofficial percentage-to-grade conversion.

MYP Standard Mathematics Assessment MYP IB Math Exam Tips

MYP Standard Mathematics eAssessments are marked externally by trained IB examiners, not by the student’s mathematics teacher. Examiners use question-specific markschemes aligned with the four MYP mathematics assessment criteria. The raw marks are then combined and converted into a final subject grade from 1 to 7.

This article explains who marks the examination, how its three tasks assess the criteria, how partial credit works, and what students should expect on exam day. Coordinators should always follow the current session’s IB instructions where local arrangements vary.

Who marks the MYP Standard Mathematics eAssessment?

The mathematics eAssessment is an on-screen examination. According to the IB’s overview of MYP assessment and examinations, on-screen examinations are externally marked by trained IB examiners.

This differs from an ePortfolio or personal project, which involves teacher marking and external moderation. Mathematics teachers use the MYP criteria throughout the course, but they do not determine the official examination mark.

Examiners apply a markscheme to each submitted response. Some questions use point-based marking, while investigations and modelling problems require judgment about reasoning, interpretation, communication, and justification.

Which mathematics criteria are assessed?

The official MYP Mathematics subject brief identifies four equally weighted criteria:

Criterion A: Knowing and understanding -- selecting and applying appropriate mathematics.
Criterion B: Investigating patterns -- identifying relationships, forming rules, and justifying them.
Criterion C: Communicating -- using clear notation, representations, reasoning, and mathematical language.
Criterion D: Applying mathematics in real-life contexts -- modelling situations, interpreting results, and evaluating whether answers are reasonable.

In the examination, individual questions carry raw marks linked to these criteria. This allows examiners to award credit for specific evidence, including partially correct work.

How the three examination tasks are marked

The subject brief organizes the examination into three tasks. Each has a principal focus, while Criterion C is assessed throughout.

Examination task	Main criteria assessed	Indicative marks
Knowing and understanding	Criteria A and C	31--35
Investigating patterns	Criteria B and C	31--35
Applying mathematics in real-life contexts	Criteria C and D	31--35

Criterion C contributes 25 marks across the three tasks. Correct notation, labelled graphs, logical explanations, and appropriate mathematical vocabulary therefore matter across the examination.

Knowing and understanding

These questions test whether students can select and apply mathematical knowledge in familiar and unfamiliar situations. Accuracy matters, but a correct method may receive partial credit when a later arithmetic mistake produces the wrong answer. Students should show enough working for the examiner to identify their approach.

Investigating patterns

An investigation requires more than continuing a sequence. A strong response identifies a pattern, proposes a general rule, tests it, and explains why it works. For example, writing $T_n=3n+2$ without supporting calculations or justification may earn only some of the available marks.

Applying mathematics in real-life contexts

These questions assess how effectively students translate a situation into mathematics and interpret the result. They may need to choose a model, calculate an answer, discuss limitations, or assess reasonableness. If a model produces $12.6$ buses, the student should interpret that value appropriately in context.

How raw marks become a grade

After the responses are marked, the raw marks are combined. The IB then applies its grade-award process and reports a final mathematics grade from 1 to 7.

The process is criterion-related, meaning grades represent demonstrated standards rather than a fixed proportion of candidates. A classroom percentage should not be assumed to equal a particular IB grade. The IB’s grading and awards guidance confirms that each eAssessment subject receives a 1-to-7 grade.

Exam-day logistics

Mathematics on-screen examinations last two hours and are held during the May and November sessions. The examination is installed locally on an approved computer rather than delivered through an ordinary website.

The interface may include an on-screen calculator, graphing functions, drawing tools, interactive material, and several response formats. Students can explore these features through the IB’s on-screen examinations overview.

Schools manage devices, rooms, arrival times, invigilation, and permitted materials under IB regulations. The IB’s exam preparation guidance explains the familiarization materials and technical tools provided to schools.

How to protect marks

Students should make their mathematical thinking visible:

Show important substitutions and intermediate steps.
Define variables and include units.
Label graphs and use accepted notation.
State and justify general rules.
Interpret answers in their original context.
Check rounding and reasonableness.
Follow command terms such as justify, verify, and comment.

A correct answer may not earn every mark when explanation is required. Conversely, an incorrect final answer may still receive credit for valid progress. When time is limited, writing a relevant formula, substitution, diagram, or first step is better than leaving the response blank.

Students can review how MYP Mathematics is assessed, practise with the MYP Standard Mathematics Questionbank, or follow a 30-day MYP eAssessment study plan.

Conclusion

MYP Standard Mathematics eAssessments are marked by trained IB examiners using markschemes connected to Criteria A, B, C, and D. Students earn marks by showing methods, reasoning, communication, and interpretation rather than entering final answers alone. RevisionDojo’s Standard Mathematics resource hub, Questionbank, and timed practice can support preparation alongside official IB familiarization materials.
