Can two MYP schools give different Mathematics grades for similar work?

Yes, particularly when the grades come from internally created classroom assessments. Both schools should use the same IB Mathematics criteria, but their tasks, available evidence, scaffolding, and teacher judgments may differ. Departments are expected to standardize marking internally so that teachers at the same school interpret the criteria consistently. Ordinary Mathematics coursework is not externally moderated across all schools, so perfect international equivalence cannot be assumed. Official eAssessment grades are more comparable because the assessment and marking are controlled by the IB.

Does every MYP Standard Mathematics student take the same final examination?

No, because MYP eAssessment is optional for schools outside the required personal project arrangements. Many students receive only school-determined Mathematics grades based on internal assessments. Students registered for official Mathematics eAssessment take the authorized on-screen examination for their session and response language. Those examinations are externally marked using IB procedures. A coordinator can confirm whether a student has been formally registered for an IB Mathematics eAssessment result.

Are MYP Standard Mathematics grade boundaries fixed every year?

The familiar internal boundary guidelines convert a criterion total out of 32 into a grade from 1 to 7. Official eAssessment boundaries work differently and may change by subject and examination session. The IB establishes those boundaries through grade awarding after considering how marks correspond to the published standards. Students should therefore avoid treating a previous session's raw-mark boundary as a guaranteed target. Only the boundary confirmed for the relevant Mathematics session determines the official result.

Is an MYP Mathematics criterion level the same as a percentage?

No, a criterion level is a judgment about the quality of demonstrated achievement against a descriptor. For example, a level 6 does not officially mean that a student earned 75% on a test. Teachers consider how well the work satisfies the strands of the relevant criterion and select the best-fitting level. The four criterion levels can then be added to make a total out of 32 for internal reporting. Any percentage shown alongside the MYP result is normally part of a school's local reporting system rather than a universal IB conversion.

Can an internal Mathematics grade differ from the eAssessment grade?

Yes, because the two results are based on different evidence. An internal grade may represent work completed across several units, task types, and reporting periods, while the eAssessment grade comes from a timed on-screen examination. The internal work is marked by teachers, whereas the examination is marked through the IB's external process. Differences in timing, examination technique, task demand, or the evidence available can affect the outcomes. Schools should investigate a large discrepancy, but a difference does not by itself establish a marking error.

How can coordinators improve Mathematics grading consistency within a school?

Coordinators should schedule regular standardization in which teachers independently mark common samples and compare their judgments. Discussion should focus on the published criterion descriptors, task-specific clarifications, and the evidence supporting borderline levels. Departments should also document how best-fit levels are determined and ensure that all four criteria are assessed sufficiently. Reports must distinguish clearly between criterion levels, totals out of 32, final 1--7 grades, and any local percentage conversion. Reviewing patterns in student work over time helps identify teachers or tasks that may be unusually generous, harsh, or inconsistent.

MYP Standard Mathematics Assessment MYP IB Math IB Grading

MYP Standard Mathematics grading is consistent in its framework, but not always identical in its application. All authorized MYP schools assess mathematics through the same four IB criteria and achievement-level structure. However, schools create and mark most classroom assessments locally, so similar work may receive slightly different internal grades.

The optional MYP Standard Mathematics eAssessment is different. It is set and externally marked by the IB, making official eAssessment results more directly comparable across participating schools.

What is consistent across MYP schools?

The IB overview of MYP assessment explains that teachers assess prescribed subject-group objectives using IB criteria. Mathematics has four equally weighted criteria:

Criterion	What it assesses
A: Knowing and understanding	Selecting and applying mathematics accurately
B: Investigating patterns	Identifying patterns, forming rules, and verifying conclusions
C: Communicating	Using notation, representations, terminology, and logical organization
D: Applying mathematics in real-life contexts	Modelling situations, interpreting results, and evaluating solutions

Each criterion has a maximum achievement level of 8, producing a total out of 32. Achievement bands such as 1--2, 3--4, 5--6, and 7--8 are defined through IB descriptors rather than invented by individual teachers.

The RevisionDojo explanation of MYP Mathematics criteria examines each criterion in more detail. These criteria matter because MYP Mathematics assesses investigation, communication, modelling, and justification as well as accurate answers.

Why internal Mathematics grades can differ

Most classroom assessment is internal. Teachers design tasks, select content and contexts, judge the evidence, and determine achievement levels through professional judgment.

Differences can arise because:

schools set tasks of different difficulty
students receive different scaffolding or preparation
teachers interpret borderline evidence differently
criteria are assessed at different stages
schools add local percentages or letter grades
local curriculum requirements affect course content

Schools cannot disregard IB criteria. Mathematics departments are expected to standardize their interpretation of the criteria by comparing samples, discussing borderline work, and agreeing what performance at each level looks like.

This improves consistency within a school, but ordinary Mathematics coursework is not externally marked or moderated by the IB. An internal grade 6 at two schools is intended to describe comparable achievement, but it may come from different tasks and has not necessarily received independent verification.

How internal grades are calculated

Teachers review the available evidence for each criterion and determine the level that best represents the student's demonstrated achievement. This is a best-fit judgment, not necessarily an arithmetic average of every score earned during a term.

The four criterion levels are added to produce a total out of 32. Schools using the MYP 1--7 reporting scale then apply the IB boundary guidelines:

Criterion total	Final MYP grade
1--5	1
6--9	2
10--14	3
15--18	4
19--23	5
24--27	6
28--32	7

These are criterion-total guidelines, not raw examination percentages. A criterion level 6 does not mean that a student answered 75% of a test correctly. It means the work best matches the relevant level descriptor.

For example, levels of 6, 5, 6, and 5 produce 22 out of 32, which falls within the grade 5 boundary of 19--23. Increasing one criterion by one level would produce 23 and remain a grade 5; increasing it by two levels would produce 24 and cross into grade 6. The RevisionDojo MYP grade-boundary guide explains this conversion further.

Is MYP Standard Mathematics eAssessment consistent?

Yes. Students registered for official MYP eAssessment complete an end-of-course on-screen examination. The IB Mathematics subject brief explains that it assesses knowing and understanding, investigating patterns, and applying mathematics in real-life contexts, with communication assessed throughout.

The process is globally controlled:

Candidates complete the authorized examination for their session.
IB-appointed examiners use common markschemes and standards.
Examiner standardization and quality controls support consistent marking.
The IB conducts subject-specific grade awarding.
Results are reported on the 1--7 scale.

A school does not determine the official mark or final grade boundary. This gives eAssessment results stronger cross-school comparability than internally determined grades.

The assessment remains criterion-related rather than norm-referenced. Students are judged against established standards, not placed into grades according to a predetermined percentage distribution.

How eAssessment grade boundaries work

The internal 32-point table should not be applied directly to an on-screen examination mark. Official eAssessment uses subject- and session-specific boundaries that convert raw examination marks into grades.

Subject experts consider how performance corresponds to grade descriptors. Boundaries may change to account for differences in examination demand between sessions. Therefore:

previous boundaries are not guaranteed to apply again
Extended Mathematics boundaries cannot be used for Standard Mathematics
unofficial percentage predictions are not official results
the confirmed boundary applies consistently to candidates in that session

The IB's eAssessment grading explanation describes how final grading remains criterion-related even though responses initially receive marks. RevisionDojo also provides a guide to MYP eAssessment length and grading.

Internal grade versus official eAssessment

Feature	Internal school grade	Official eAssessment
Task created by	School or teacher	IB
Marked by	Classroom teacher	IB-appointed examiners
Standardization	Within the school	Across the examining system
Boundary basis	Total out of 32 and reporting policy	Session-specific IB grade award
Official IB course result	No	Yes
Comparability	Intended, but not exact	Strongly standardized

The 2026 MYP general regulations clarify that ordinary school-assessed Mathematics coursework does not contribute to official MYP Course Results. The externally marked examination produces the official Mathematics eAssessment grade.

What students should check

Students should establish whether a reported result is an internal grade, predicted eAssessment grade, or final IB result. These labels are not interchangeable. They should also ask how best-fit levels are determined, which boundary table is used, and whether local percentages have been added.

For external assessment, students should practise the full range of mathematical demands rather than target an assumed percentage. Useful support includes RevisionDojo's MYP Standard Mathematics resources, Mathematics Questionbank, and guide to MYP Mathematics assessment and revision.

Common misconceptions

Every MYP school gives the same test. Schools normally design internal assessments; only official eAssessment candidates complete the standardized IB examination.

A grade 7 always requires the same percentage. Criterion levels are not percentages, while eAssessment boundaries may vary between sessions.

Teachers must average every task. Internal assessment uses best-fit professional judgment against descriptors. A simple average can conceal improvement or combine tasks assessing different criteria.

Internal and eAssessment grades must match. The results use different evidence and marking arrangements, so a difference does not automatically indicate an error.

Conclusion

MYP Standard Mathematics uses common criteria, achievement levels, and a 1--7 reporting scale across authorized schools. Nevertheless, internal grades depend on locally designed tasks and teacher judgments, so complete school-to-school uniformity cannot be guaranteed.

Official eAssessment results are more comparable because the examination, external marking, and grade award are controlled by the IB. Students should identify the type of grade before interpreting it. RevisionDojo's Study Notes, Questionbank, Mock Exams, and Jojo AI can then support focused, criterion-aware preparation.
