MYP Physics grading can look more complicated than the physics itself. A child brings home a 5 out of 8, then receives a 6 out of 7 on a report. It is reasonable to wonder whether the numbers have changed meaning.
They have. The simplest parents guide to MYP Physics grading is this: teachers assess four scientific capabilities, each on a 0--8 scale. Those criterion levels are then combined to produce an overall subject grade from 1 to 7. Students are assessed against published performance descriptions rather than ranked against classmates.
Once you separate criterion levels from the final grade, the system becomes calmer. You can focus on what your child needs to demonstrate next without becoming their second physics teacher.
MYP Physics grading at a glance
- Physics uses four equally weighted science criteria: A, B, C and D.
- Each criterion has a maximum achievement level of 8.
- Teachers apply descriptors using best-fit judgment, not a percentage calculation.
- The four criterion levels can produce a total of 32.
- Schools commonly convert that total into an overall grade from 1 to 7.
- Official Year 5 eAssessment boundaries are set for each assessment session.
- Productive feedback identifies the criterion, missing evidence and next action.

What the four MYP Physics criteria measure
A physics grade records more than formula recall. It considers whether a student can understand ideas, design investigations, interpret evidence and examine how science affects the world.
| Criterion | What it assesses | A useful parent question |
|---|---|---|
| A: Knowing and understanding | Explaining physics, applying knowledge and making supported judgments | “Why does that equation apply here?” |
| B: Inquiring and designing | Forming hypotheses, identifying variables and designing investigations | “How will you make this a fair test?” |
| C: Processing and evaluating | Presenting data, interpreting results and evaluating methods | “What does the evidence show?” |
| D: Reflecting on the impacts of science | Evaluating scientific applications, implications and sources | “What benefits and trade-offs might this create?” |
A student may be confident with calculations yet receive different levels across the criteria. Strong Criterion A work does not automatically demonstrate that the student can evaluate experimental limitations in Criterion C. The variation is a diagnosis, not an inconsistency.
Expectations also become more demanding as students progress. Families should use the task-specific rubric supplied by the teacher. RevisionDojo's guide to MYP assessment criteria explains how rubric-aware practice can support improvement.
Why 4 out of 8 does not mean 50%
Criterion levels describe the quality of demonstrated performance. They are not conventional percentages.
Descriptors are grouped into bands such as 1--2, 3--4, 5--6 and 7--8. Teachers review the evidence and select the level that best fits the relevant description. Higher bands may require more accurate explanation, independence, justification or application in unfamiliar situations. They do not simply require twice as many correct facts.
Teachers consider an appropriate body of evidence when determining achievement. A weak early attempt need not define the year if later work demonstrates growth. One assignment also may not assess every criterion.
How criterion levels become a final grade
For an internal report, the four criterion levels may be added into a total out of 32 and converted into a grade from 1 to 7. Many schools use the following boundaries, although parents should confirm the school's reporting policy.
| Criterion total | Overall grade |
|---|---|
| 0--5 | 1 |
| 6--9 | 2 |
| 10--14 | 3 |
| 15--18 | 4 |
| 19--23 | 5 |
| 24--27 | 6 |
| 28--32 | 7 |
Suppose a student receives A=7, B=4, C=5 and D=6. The total is 22, but the useful conversation concerns Criterion B. The student may understand forces while needing to justify variables, data collection or investigation methods.
RevisionDojo's guide to MYP grade boundaries and the 1--7 scale explains the distinction between criterion levels and overall grades.
Official MYP eAssessment is different. Students seeking formal course results in Physics complete an on-screen examination, and the IB sets subject-specific boundaries for each session. Families should not apply an internal 32-point conversion table to an official examination mark.
How to read a Physics report calmly
Start with the criteria rather than the headline grade. Ask:
- Which criterion is strongest?
- Which offers the clearest improvement opportunity?
- What specific wording appears in the feedback?
Turn that feedback into an observable action. “Improve physics” is too broad. “Label graph axes with quantities and units” is useful. So is “justify why control variables must remain constant.”
If the feedback remains unclear, ask the teacher which criterion should be prioritized and what evidence would show progress. This keeps the conversation focused on learning rather than negotiating marks.
Supporting your child without adding pressure
Hold one ten-minute weekly check-in. Ask your child to identify one strength, one missing skill and one action. The guide to supporting a child in the MYP provides further low-pressure questions.
You do not need to remember every circuit rule. Ask, “What evidence supports that conclusion?” or “Why did you choose this equation?” Explaining reasoning aloud can reveal gaps without turning home into another classroom.
Match practice to the criterion. For Criterion A, combine MYP Physics Study Notes with the Physics Questionbank. For Criterion B, practise hypotheses and methods. For Criterion C, analyse graphs and limitations. For Criterion D, discuss the consequences of technologies.
Keep revision brief and repeatable. A session could include 15 minutes of MYP Physics Flashcards, 20 minutes of questions and five minutes reviewing one mistake.
A calmer path forward
Look for patterns across several tasks before adding support. Repeated conceptual confusion, difficulty applying feedback or growing assessment anxiety may justify teacher or tutor guidance.
The complete MYP Physics resource hub connects Study Notes, Flashcards, Questionbank and AI Chat with Grading tools, Predicted Papers, Mock Exams, the Coursework Library and Tutors. RevisionDojo is the ultimate IB resource because each tool can serve one clear next step without removing student ownership.
Notice the criterion. Read the descriptor. Choose one action. Then allow time for stronger evidence to emerge. The goal is not constant pressure toward an 8. It is helping your child understand what progress looks like and believe that the next step is manageable.
