MYP Physics is assessed through four equally weighted sciences criteria, each with a maximum achievement level of 8. They measure scientific knowledge, investigation design, data analysis, evaluation, and reflection on how science affects society. In MYP Year 5, participating schools may also enter students for an external on-screen examination that produces an IB-validated result.
Success therefore requires more than remembering formulas. Students must apply physical principles, plan valid investigations, interpret evidence, evaluate methods, and communicate scientifically. Understanding these demands is the basis of effective MYP Physics revision.
The four MYP Physics assessment criteria
Physics belongs to the MYP sciences subject group, so it uses the same criteria as biology, chemistry, and integrated sciences. Teachers assess all strands during the course and use published descriptors to make a best-fit judgment about the level demonstrated.
| Criterion | What it assesses | Maximum level |
|---|---|---|
| A: Knowing and understanding | Explaining physics, applying knowledge, and making supported judgments | 8 |
| B: Inquiring and designing | Developing questions, hypotheses, variables, and investigation methods | 8 |
| C: Processing and evaluating | Presenting data, interpreting results, evaluating conclusions, and improving methods | 8 |
| D: Reflecting on the impacts of science | Evaluating scientific applications and their implications | 8 |
Criterion A: Knowing and understanding
Criterion A tests factual understanding and the ability to apply it. You may calculate speed using , interpret a motion graph, explain how resultant force affects acceleration, or analyse information before reaching a scientifically supported judgment.
Strong answers select the correct principle, show logical working, include units, and explain what the result means. Memorizing equations is insufficient if you cannot decide when or why they apply, so practise unfamiliar problems in which the required formula is not identified.
Criterion B: Inquiring and designing
Criterion B assesses how well you plan an investigation. You may need to develop a testable research question, formulate a hypothesis supported by physics, identify variables, and design a safe, repeatable method.
In a pendulum investigation, for example, length could be the independent variable and period the dependent variable. Release angle and pendulum mass might be controlled. A strong method specifies equipment, measurement procedures, values and intervals, repeated trials, safety measures, and how enough relevant data will be collected.
Criterion C: Processing and evaluating
Criterion C usually follows practical work. It assesses whether you can organize and transform data, construct suitable graphs, identify patterns, explain results, judge a hypothesis, and evaluate the method.
Tables and graphs need headings, units, suitable precision, and correctly placed variables. Conclusions should cite actual evidence. When evaluating, replace vague phrases such as “human error” with a specific limitation, its effect, and a realistic improvement. For example, manual reaction time may make stopwatch readings inconsistent, so video analysis or an electronic sensor could improve precision.
Criterion D: Reflecting on the impacts of science
Criterion D connects physics with real decisions. Tasks may ask you to explain an application and evaluate its environmental, economic, ethical, political, social, or cultural implications.
A response about nuclear power should explain relevant physics, examine competing consequences, use credible evidence, and reach a balanced conclusion. Merely listing advantages and disadvantages is not evaluation. The command term evaluate requires a justified judgment, while complete documentation of sources supports scientific credibility.
How criterion levels become an MYP grade
The four criterion levels are added to produce a total out of 32. Standard MYP boundaries convert that total into a final grade from 1 to 7.
| Total criterion level | Final MYP grade |
|---|---|
| 1-5 | 1 |
| 6-9 | 2 |
| 10-14 | 3 |
| 15-18 | 4 |
| 19-23 | 5 |
| 24-27 | 6 |
| 28-32 | 7 |
This is criterion-related assessment, not ranking against classmates. Teachers do not necessarily average every mark collected during the year. They review the available evidence and determine the level that best represents sustained achievement in each criterion. Schools may use separate percentages for interim reports, so a classroom percentage is not automatically an official MYP grade.
Internal assessment and practical work
Teachers create and mark classroom assessments using the official criteria. Evidence may come from topic tests, laboratory reports, investigation plans, data-analysis tasks, presentations, or research-based evaluations.
Practical investigations commonly assess Criteria B and C, although planning and analysis may be assessed separately. Read the task-specific clarification or rubric supplied by your teacher because it translates the general descriptors into expectations for that assignment without changing the underlying standard.
How the MYP Physics eAssessment works
The MYP eAssessment is an external on-screen examination available in the final year. It is used for an IB-validated physics course result and may contribute towards the MYP certificate. Participation is optional for schools, so not every MYP Physics student takes it.
The official IB MYP sciences subject brief describes a two-hour examination organized around three task types:
| eAssessment task | Main criteria | Marks |
|---|---|---|
| Knowing and understanding | Criterion A | 25 |
| Investigation skills | Criteria B and C | 50 |
| Applying science | Criterion D | 25 |
Questions use unfamiliar scenarios, data, diagrams, interactive material, and investigation problems. Since half the marks concern inquiry, processing, and evaluation, revising facts alone is ineffective. The IB provides further context in its MYP assessment and examinations overview.
What content is assessed?
There is no identical lesson-by-lesson MYP Physics syllabus for every school. The MYP provides a sciences framework of concepts, objectives, and criteria, while schools organize appropriate content into units. Exact coverage and teaching order can therefore differ.
Common areas include measurement, motion, forces, energy, thermal physics, electricity, magnetism, waves, light, sound, atomic physics, and space. Experimental skills such as uncertainty, graphing, variable control, and method evaluation are also important. Use your teacher's course outline as the final authority, supported by RevisionDojo's MYP syllabus overview and MYP Physics lessons.
How to revise for MYP Physics assessment
Organize revision around both content and criteria. Each week, combine topic review with calculation questions, one investigation plan, graph or data analysis, and evaluation of a real-world application.
Use active practice rather than repeatedly reading notes. The MYP Physics Questionbank supports topic-based questions, while resources such as waves revision notes can clarify concepts first.
Pay attention to command terms. State needs a concise answer, explain requires reasons or mechanisms, analyse requires relationships, and evaluate requires a supported judgment. Answering a less demanding command term can prevent an otherwise accurate response from reaching the highest level.
Conclusion
MYP Physics uses four equally weighted criteria covering knowledge, investigation design, data evaluation, and scientific impacts. Each contributes up to 8 levels, with the total converted into a grade from 1 to 7. Some Year 5 students also take the external eAssessment.
Effective preparation combines physics knowledge with practical planning and scientific reasoning. RevisionDojo's MYP Physics materials and Questionbank are most useful alongside your teacher's course outline and the criteria for each task.
