What This Calculator Does
The IB MYP Grade Calculator turns the four criterion achievement levels you receive in a Middle Years Programme subject into the single final grade reported on the IB's 1-7 scale. Instead of guessing where your marks land, you enter each criterion level and let the tool apply your subject's official weightings and the IB grade boundary table.
- • Check a predicted grade: Students and parents can estimate the final 1-7 grade from current criterion levels before reports are issued.
- • Plan improvement: You can see which criterion level needs to rise to cross the next grade boundary.
- • Verify school maths: Teachers and coordinators can confirm that a weighted percentage matches the grade their marks suggest.
The International Baccalaureate assesses every MYP subject through four separate criteria rather than a single exam percentage. That structure is helpful for feedback, but it makes the final number harder to read at a glance, which is where this calculator helps.
Because weightings differ between subject groups, a raw average of your four levels is not always the right answer. The calculator keeps the weighting step explicit so the result reflects how your school actually combines the criteria.
If you already have a percentage mark rather than MYP criterion levels, the percentage to GPA calculator shows how that percentage sits on a different grading scale.
How the Grade Conversion Works
The tool follows the same path the IB uses: weight each criterion level, add the weighted levels, convert to a percentage, then match that percentage to the official grade boundaries.
- Criterion levels A-D: Your achievement level on each of the four MYP criteria, each from 0 to 8.
- Criterion weights wA-wD: The percentage each criterion contributes to the subject grade, set by your subject group and summing to 100.
- Overall percentage: The weighted sum divided by the 800-point maximum, expressed as a percentage of the available achievement.
The maximum possible weighted score is always 8 times the total weighting, which is 800 points when the weights sum to 100%. That fixed maximum is what makes the percentage comparable across subjects even when the weight split changes, which is why an IB MYP grade calculator can report a single 1-7 result from any subject.
Once the percentage is known, the grade boundary table maps it to a final grade. The bands are fixed: 96-100% is a 7, 83-95% a 6, 70-82% a 5, 56-69% a 4, 43-55% a 3, 28-42% a 2, and 0-27% a 1.
Sciences student, equal weightings
Levels 6, 6, 5, 5 with 25% on each criterion.
(6+6+5+5) / 32 x 100 = 68.75%.
Final grade: 4 (56-69% band).
With equal weightings the percentage equals the simple average of the levels divided by 8.
Mathematics student, 30/30/20/20 weighting
Levels 6, 5, 5, 4 with Criterion A and B at 30%, C and D at 20%.
(6x30 + 5x30 + 5x20 + 4x20) / 800 x 100 = 63.75%.
Final grade: 4 (56-69% band).
The heavier A and B weights pull the result toward the stronger criterion levels.
According to International Baccalaureate - MYP assessment and exams, each MYP subject is assessed through four criteria on a 0-8 achievement scale and reported as a final grade on the 1-7 scale
As published by International Baccalaureate - MYP: From principles to practice, the final MYP grade uses fixed achievement boundaries, with 96-100% earning a 7 and the lowest awarded grade of 1 covering 0-27%
Because MYP subjects apply different criterion weightings, the GPA to percentage converter works the same weighted-conversion idea in the other direction.
Key MYP Grading Concepts
A few ideas explain why the MYP grades the way it does, and why this calculator needs more than a simple average.
Achievement level (0-8)
A whole-number judgement of how well a student met a criterion, from 0 (not achieved) to 8 (excellent). Each subject has four of them.
Criterion weighting
The share of the final subject grade contributed by each criterion. Most groups use 25% each; Individuals and societies and Mathematics use 30/30/20/20.
Grade boundary table
The fixed percentage bands the IB uses to convert an overall percentage into a final 1-7 grade, with no gaps across 0-100%.
1-7 final grade
The single grade reported for an MYP subject, where 7 is the highest demonstration of the assessed objectives and 1 is the lowest awarded grade.
The 0-8 scale is designed so teachers judge attainment against published criterion strands rather than against other students, which keeps results consistent between schools.
Weighting is what lets a subject emphasise the skills most central to it, so the same set of levels can produce a different grade in an IB MYP grade calculator depending on the subject group.
The 1-7 MYP scale is one of several grading scales you may meet; our cumulative GPA calculator tracks how term results build into a running average.
How to Use This Calculator
You only need your four criterion levels and your subject group to get a result.
- 1 Choose your subject group: Select the MYP subject group from the list; the official criterion weightings load automatically.
- 2 Enter your four criterion levels: Type your achievement level (0-8) for Criteria A, B, C and D as shown on your assessment feedback.
- 3 Leave weights at 0 unless overriding: Keep the weight fields at 0 to use official weightings, or enter custom percentages if your school uses a modified scheme.
- 4 Read the final grade and band: The calculator shows the overall percentage, the final 1-7 grade, and the exact boundary band it reached.
A Sciences student with levels 7, 6, 6 and 6 sees an overall percentage of 78.1% and a final grade of 5, because 70-82% is the grade 5 band.
Standardised assessments combine section results differently, and the ACT score calculator shows how weighted sections become a composite score.
Why Use This Calculator
The value is in making the weighting and boundary steps visible rather than hidden.
- • Correct weighting by subject: It applies the right 25% or 30/20 split for your subject group, avoiding the common error of a plain average.
- • Boundary transparency: You see the exact percentage band your result falls into, so a near-miss grade is obvious.
- • Quick what-if checking: Adjust a single criterion level to see how few points separate one grade from the next.
- • Confidence before reports: Students and parents get an early, source-based estimate of the final grade.
Many spreadsheet templates hard-code one subject's weights and silently mis-score another. Keeping the weighting explicit prevents that mistake.
Because the boundary bands are fixed and gap-free, an IB MYP grade calculator will match the IB's conversion whenever your inputs are the official criterion levels.
Seeing where a score lands against a boundary is useful for any test, which is what the SAT score percentile calculator does for SAT results.
What Affects Your MYP Grade
Two things move the final grade: the criterion levels themselves and how those levels are weighted.
Criterion level spread
A single low criterion drags the percentage down less when its weight is small, and more when it carries 30% of the grade.
Subject-group weighting
The 30/30/20/20 split in Mathematics and Individuals and societies rewards strength in Criteria A and B more than in C and D.
Near-boundary percentages
Small improvements matter most just below a boundary; one extra level can cross from grade 4 into grade 5.
Custom school weightings
If your school modifies the official split, entering those weights keeps the estimate accurate.
- • This calculator estimates the grade from criterion levels and does not replace official IB moderation or eAssessment of coursework.
- • It assumes the standard 1-7 boundary table; a school using a different conversion should not rely on the result.
The estimate is only as good as the levels you enter. Reported MYP levels are whole numbers, so decimals should not be used as inputs.
Where a school applies additional internal rules or the IB withholds a grade for missing components, the percentage alone cannot capture that outcome.
According to International Baccalaureate - MYP subject group criteria, Individuals and societies and Mathematics weight Criterion A and B at 30% and Criteria C and D at 20%, while most other groups use equal 25% weightings
Once you know the grade you are targeting, the exam preparation countdown calculator helps plan the study time left before the assessment.
Frequently Asked Questions
Q: How is the IB MYP final grade calculated from the four criteria?
A: Each MYP subject is assessed through four criteria, A, B, C and D, and every criterion is graded on an achievement scale from 0 to 8. Your school applies a weight to each criterion (most subjects use 25% each, while Individuals and societies and Mathematics weight two criteria at 30% and the other two at 20%). The weighted levels are added up, divided by the maximum possible weighted score of 800, and turned into a percentage. That percentage is then matched to the IB's grade boundary table to give the final 1-7 grade.
Q: What are the official IB MYP grade boundaries for grades 1 to 7?
A: The IB reports the MYP final grade on a 1-7 scale using fixed achievement boundaries: 7 is 96-100%, 6 is 83-95%, 5 is 70-82%, 4 is 56-69%, 3 is 43-55%, 2 is 28-42%, and 1 is 0-27%. These bands cover every percentage from 0 to 100 with no gaps, so any overall score maps to exactly one grade.
Q: Do all MYP subjects use the same criterion weightings?
A: No. Most subject groups (Arts, Design, Language acquisition, Language and literature, Physical and health education, and Sciences) weight the four criteria equally at 25% each. Individuals and societies and Mathematics instead weight Criterion A and B at 30% and Criterion C and D at 20%. The calculator loads the correct weightings the moment you choose a subject group, and you can override them if your school uses a modified scheme.
Q: What is an MYP achievement level and why is it scored 0 to 8?
A: An achievement level is the IB's judgement of how well a student has met a criterion, reported as a whole number from 0 (not achieved) to 8 (excellent). The 0-8 scale keeps judgements consistent across teachers and schools, and because every criterion tops out at 8 the maximum weighted score is always 8 x 100 = 800 points regardless of the weighting split.
Q: Is this calculator valid for the MYP eAssessment and personal projects?
A: It models the same weighting and grade-boundary logic the IB uses for on-screen eAssessments and the personal project, where a single final subject grade on the 1-7 scale is produced from criterion levels. It does not replace official results: schools may set additional rules, and the IB moderates or eAssesses coursework before a grade is awarded.
Q: What happens if my overall percentage falls below the grade 1 boundary?
A: The lowest awarded grade is 1, which spans 0-27%. Any overall percentage in that range, including a score of 0% when every criterion is at level 0, still receives a grade of 1 rather than a 0. A result of 'not awarded' is a separate outcome the IB applies in specific circumstances, such as missing components, and is not produced by the percentage alone.
