OCR and Edexcel are both widely offered A-level Psychology specifications. Both cover the core psychological approaches and research methods required by Ofqual. The main differences are in which optional topics are available, how research methods are assessed, and the style of exam questions students encounter in the final papers.
What core content do both specifications cover?
All A-level Psychology specifications must include the major psychological perspectives (biological, cognitive, behavioural, psychodynamic, humanistic), research methods, and at least one applied topic. Both OCR and Edexcel fulfil this requirement.
OCR Psychology (H567) covers four compulsory components: social psychology, cognitive psychology, developmental psychology, and biological psychology, plus a range of applied topics including criminal psychology, sport and exercise, and issues in mental health. Research methods are assessed throughout all papers.
Edexcel Psychology (9PS0) covers biological psychology, social psychology, cognitive psychology, and clinical psychology (abnormality) in the core, plus optional content drawn from criminological, child, health, and sport psychology. Edexcel's specification places particular emphasis on contemporary research and includes a component specifically on psychological skills and methods.
How is research methods assessed in each?
Research methods is where OCR and Edexcel differ most clearly.
OCR integrates research methods questions across all three papers. Students are expected to apply methodological knowledge to novel scenarios and evaluate study designs in the context of the topic being examined. There is no standalone research methods paper; the methods knowledge is woven throughout.
Edexcel includes a dedicated component focusing on psychological skills, which covers planning, conducting, and reporting research alongside mathematical skills. This component appears in Paper 3 alongside the optional topics. Edexcel is known for its requirement that students carry out four set practical investigations during the course; questions in the exams reference these practicals, making the methods content more grounded in experience.
Side-by-side comparison
| Feature | OCR Psychology (H567) | Edexcel Psychology (9PS0) |
|---|---|---|
| Papers | 3 × 2 hours | 3 papers (variable timing) |
| Research methods | Integrated throughout | Dedicated component (Paper 3) |
| Set practical investigations | Yes (required) | Yes (4 required) |
| Core topics | Social, cognitive, developmental, biological | Biological, social, cognitive, clinical |
| Applied / optional topics | Criminal, sport, mental health, child, others | Criminal, child, health, sport psychology |

| Mathematical skills | Present throughout | Explicit in Paper 3 |
| Extended writing | Yes — all papers | Yes — particularly in Papers 1 and 3 |
How does Edexcel's clinical psychology component work?
A distinctive feature of Edexcel is that clinical psychology (the study of mental health, abnormality, diagnosis, and treatment) is a mandatory component rather than an optional one. All Edexcel students study depression, OCD, and phobias, alongside debates about diagnosis. This makes Edexcel particularly coherent for students interested in mental health careers or psychology degrees, because clinical content is guaranteed rather than optional.
OCR offers mental health as an applied optional topic, meaning not all students will study it — it depends on what their school chooses to teach.

Frequently asked questions
Do psychology degree programmes prefer OCR or Edexcel A-level Psychology?
No UK psychology department publishes a preference. Both specifications develop the research methods awareness and psychological literacy that university programmes expect. What matters more is whether students have taken a science or social science A-level alongside Psychology, which strengthens research methods preparation.
Is Edexcel Psychology harder than OCR?
Both are comparable in overall demand. Edexcel's mandatory clinical component and its dedicated methods paper can feel more demanding initially, but the structured approach helps students who prefer clear divisions between topics. OCR's integrated methods approach suits students who engage well with methods in context. Grade boundaries for both adjust annually, making long-term difficulty comparisons unreliable.
What are the four required practicals in Edexcel Psychology?
Edexcel requires students to carry out one practical in each of the four areas covered by the specification: biological psychology, social psychology, cognitive psychology, and the optional component. These practicals are teacher-led and typically take place during lessons. The experience of planning and conducting them directly informs the methods questions in Paper 3.
How much maths is in A-level Psychology?
At least 10% of the marks in A-level Psychology from all boards must involve mathematical skills. This includes understanding and calculating basic statistics (mean, median, mode, percentages), interpreting graphs and tables, and understanding probability. A-level Maths is not required, but students who are comfortable with numbers find the quantitative sections of both OCR and Edexcel easier to handle.
