Do teachers average all my MYP Mathematics criterion scores?

No, teachers should not automatically average every criterion score from the year. Individual task levels provide evidence that the teacher compares with the published criterion descriptors. The teacher then makes a best-fit judgment about the achievement level that most accurately represents your demonstrated performance in each criterion. Your school's assessment policy may explain how recent, sustained and comprehensive evidence is considered. Once the four final criterion levels have been established, they are added to produce the total out of 32.

What MYP Standard Mathematics criterion total is needed for a grade 7?

Under the standard MYP boundary guidelines, a combined criterion total of 28 to 32 produces a final grade 7. Since there are four criteria, this could result from levels of 7, 7, 7 and 7, but it does not require the same level in every criterion. Levels of 8, 8, 6 and 6 would also total 28. Students should verify the reporting table used by their school rather than assuming that every locally issued grade follows an identical policy. For external eAssessment, the IB uses raw-mark boundaries established for the relevant subject and session instead of the classroom 32-point table.

Can a student receive a final grade 6 without scoring level 6 in every criterion?

Yes, because the final grade depends on the combined criterion total, not on matching the same number in every criterion. For example, levels of 7, 7, 5 and 5 produce a total of 24, which normally converts to grade 6. Uneven criterion levels can therefore lead to the same final grade as four level 6 results. Nevertheless, a weak criterion can restrict the total and may indicate an important skill gap. Students should use criterion-specific feedback to improve the underlying performance rather than treating the total as the only meaningful result.

Is a criterion level of 8 the same as an MYP grade 7?

No, these numbers belong to different stages of the grading system. A criterion level of 8 describes achievement in one area such as knowing and understanding or communicating. A final grade of 7 summarizes performance across all four criteria after their levels have been combined. Four criterion levels can total a maximum of 32, and the applicable boundary table converts that total into the 1--7 grade. Confusing the two scales can lead students to misread task feedback and report grades.

Are MYP Standard and Extended Mathematics graded in the same way?

Both courses use the four Mathematics criteria: Knowing and understanding, Investigating patterns, Communicating, and Applying mathematics in real-life contexts. In school-based assessment, each criterion has a maximum achievement level of 8, and the four final levels can total 32. However, extended mathematics contains additional breadth and depth, so the mathematical demands used to produce evidence are not identical. Standard and extended on-screen examinations are also separate assessments with their own raw marks and applicable grade boundaries. A grade earned in one course should therefore be interpreted in relation to that course's content and assessment demands.

Can I convert an eAssessment percentage using the MYP 32-point grade boundary table?

No, an eAssessment percentage should not be inserted into the classroom criterion boundary table. The 32-point table is designed for four final criterion achievement levels, each worth up to 8. In external MYP Standard Mathematics eAssessment, IB examiners award raw marks for responses using authorized marking materials. The IB then sets or applies subject- and session-specific boundaries to convert the examination total into a grade from 1 to 7. For practice examinations, use the relevant markscheme and boundaries supplied for that paper or examination session.

MYP Standard Mathematics Criteria Levels to Final Grade

MYP Standard Mathematics Assessment MYP IB Math IB Grading

MYP Standard Mathematics criteria levels become a final grade in two stages. First, the teacher determines an achievement level from 0 to 8 for each of the four mathematics criteria. Those levels are added to produce a total out of 32, which is converted into a final subject grade from 1 to 7 using the applicable MYP boundaries.

This process applies to school-based assessment. The externally marked MYP Standard Mathematics eAssessment uses raw examination marks and subject-specific boundaries instead.

The four MYP Standard Mathematics criteria

The official IB MYP Mathematics subject brief identifies four equally weighted assessment criteria. Standard and extended mathematics use the same criterion categories, although their content and level of challenge differ.

Criterion	Official focus	Successful work demonstrates
A: Knowing and understanding	Selecting and applying mathematics	Accurate knowledge, appropriate methods and successful solutions
B: Investigating patterns	Exploring mathematical relationships	Patterns, general rules, verification and justification
C: Communicating	Presenting mathematical ideas	Correct notation, suitable representations and logical reasoning
D: Applying mathematics in real-life contexts	Modelling situations	Appropriate strategies, interpretation, conclusions and evaluation

Each criterion has a maximum level of 8. A criterion level is not a percentage, so level 6 does not mean 60 percent. It indicates that the evidence best matches the relevant published descriptor.

Because the criteria are equally weighted, strong procedural performance in Criterion A cannot replace missing evidence in Criteria B, C or D. The RevisionDojo guide to MYP Mathematics assessment explains what each area requires.

How teachers determine final criterion levels

Teachers do not normally calculate a final criterion level by averaging every result. They consider sufficient evidence from the assessment period and make a best-fit judgment against the published descriptors.

Suppose a student receives Criterion B levels of 4, 5 and 6. The result is not automatically:

\frac{4+5+6}{3}=5.

If the later level 6 shows sustained achievement across the relevant strands, the teacher may select 6. If it came from one narrow task while broader performance remained at level 4 or 5, a final level of 5 may be more defensible.

MYP assessment is therefore criterion-related, not a mechanical accumulation of scores. Teachers must follow the descriptors and their school's assessment policy. See how MYP students are graded for a broader explanation.

Converting criteria levels to a final grade

Once the final level for each criterion has been established, calculate:

T=A+B+C+D,

where each level is between 0 and 8 and the maximum total is 32. Schools commonly use these MYP boundary guidelines:

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

The standard table begins grade 1 at one point, so a total of zero requires schools to follow their authorized reporting procedures. Coordinators should also confirm the current school policy and apply it consistently.

These boundaries, summarized in RevisionDojo's MYP grade boundaries guide, must not be confused with external eAssessment raw-mark boundaries.

Worked example

Consider a Standard Mathematics student with these final best-fit levels:

Criterion	Final level	Evidence summarized
A	7	Accurate methods in familiar and unfamiliar problems
B	6	Correct general rules with verification and justification
C	5	Clear working with some organizational weaknesses
D	6	Appropriate modelling, interpretation and evaluation

The total is:

7+6+5+6=24.

A total of 24 out of 32 falls within the 24--27 range, producing a final grade of 6. If Criterion C were level 4, the total would be 23 and the result would normally be grade 5.

Students should still focus on the rubric rather than chasing one point. The important question is what evidence is missing from the weaker criterion. RevisionDojo's guide to Mathematics Criteria A, B, C and D can help identify that gap.

How MYP Standard Mathematics eAssessment is graded

The classroom calculation cannot be used to convert an external on-screen examination percentage. In optional MYP eAssessment, candidates complete a formal examination marked externally by IB examiners.

The IB subject brief describes three broad task types:

Knowing and understanding, drawing mainly on Criteria A and C
Investigating patterns, drawing mainly on Criteria B and C
Applying mathematics in real-life contexts, drawing mainly on Criteria C and D

Criterion C appears across the examination because mathematical communication is required in procedural work, investigations and modelling. Collectively, the tasks represent all four criteria.

Examiners award raw marks using authorized marking materials. The IB then applies the grade boundaries established for that subject and examination session. The outcome is a grade from 1 to 7, but it is not produced by assigning four criterion levels and adding them to 32.

School-based assessment	External Mathematics eAssessment
Teacher judges Criteria A--D using descriptors	IB examiners award raw marks
Each criterion level is out of 8	Tasks have specified mark values
Four levels produce a total out of 32	Raw marks produce an examination total
School uses its authorized reporting boundaries	IB applies session-specific boundaries

A student who earns 70 percent on a practice eAssessment should not convert it into 22.4 out of 32. The result should be interpreted using the relevant markscheme and suitable boundaries from that paper or session.

The IB's MYP grading and awards page confirms that externally assessed subjects receive grades from 1 to 7. RevisionDojo's guide to MYP eAssessment duration and marking provides further context.

Common calculation mistakes

Averaging the four criteria: The average remains on the 0--8 scale. Add the four levels and convert the total out of 32.
Averaging every task mechanically: Task results are evidence for a best-fit judgment, not necessarily equally weighted numbers.
Treating levels as percentages: Level 7 is not 70 percent. Achievement levels describe performance against qualitative criteria.
Using classroom boundaries for eAssessment: External examinations use raw marks and session-specific grade awarding.
Ignoring individual criteria: The final total matters for the grade, but each criterion reveals a different mathematical strength or weakness.

Practical advice for students and coordinators

Students should keep a tracker recording each task, the assessed criteria, levels awarded and feedback connected to particular strands. This shows whether improvement is needed in mathematical knowledge, investigation, communication or real-world application.

Coordinators should distinguish clearly among raw marks, criterion achievement levels, criterion totals and final grades. School policies should explain how teachers make best-fit judgments, gather sufficient evidence and select internal reporting boundaries.

For revision, students should practise all four forms of mathematical performance rather than only procedural questions. The MYP assessment criteria overview supports criteria-aware planning.

Conclusion

For school-based MYP Standard Mathematics, teachers determine best-fit levels for Criteria A, B, C and D, add them to obtain a total out of 32, and convert that total into a grade from 1 to 7. A total of 24, for example, normally corresponds to grade 6.

External eAssessment instead uses raw marks and IB-set, session-specific boundaries. Students must identify which grading system applies before converting any result. RevisionDojo's MYP Mathematics Study Notes, Questionbank and Jojo AI can support targeted practice across all four criteria.

The four MYP Standard Mathematics criteria

Criterion	Official focus	Successful work demonstrates
A: Knowing and understanding	Selecting and applying mathematics	Accurate knowledge, appropriate methods and successful solutions
B: Investigating patterns	Exploring mathematical relationships	Patterns, general rules, verification and justification
C: Communicating	Presenting mathematical ideas	Correct notation, suitable representations and logical reasoning
D: Applying mathematics in real-life contexts	Modelling situations	Appropriate strategies, interpretation, conclusions and evaluation

Each criterion has a maximum level of 8. A criterion level is not a percentage, so level 6 does not mean 60 percent. It indicates that the evidence best matches the relevant published descriptor.

How teachers determine final criterion levels

Suppose a student receives Criterion B levels of 4, 5 and 6. The result is not automatically:

\frac{4+5+6}{3}=5.
