AQA and Edexcel A-level Psychology are the two most widely taught psychology specifications in England. Neither has coursework — both are fully assessed through written exams. The main differences are in which topics are compulsory, how option topics are structured, the weight given to research methods, and the style of extended questions set.
What content must all A-level Psychology specifications include?
Ofqual requires all A-level Psychology specifications to cover a core set of areas:
- Social psychology (conformity, obedience, prejudice)
- Cognitive psychology (memory, thinking, attention)
- Developmental psychology (attachment, cognitive development)
- Biological psychology (brain structure, genetics, evolution in behaviour)
- Learning theories (classical and operant conditioning, social learning)
- Psychopathology (psychological disorders and their treatment)
- Research methods (quantitative and qualitative, ethics, statistics)
Both AQA and Edexcel address all of these areas. The differences are in the specific studies and theories taught under each heading, the order in which they appear across papers, and the breadth of optional topics available.
How does AQA A-level Psychology work?
AQA A-level Psychology (specification code 7182) uses three written papers, all sat at the end of Year 13.
Paper 1 (2h, 96 marks): Introductory Topics in Psychology — Social Influence; Memory; Attachment; Psychopathology. All four topics are compulsory.
Paper 2 (2h, 96 marks): Psychology in Context — Approaches in Psychology (compulsory); Biopsychology (compulsory); Research Methods (compulsory).
Paper 3 (2h, 96 marks): Issues and Options in Psychology — Issues and Debates in Psychology (compulsory), plus students study two topics from eight options: Relationships; Gender; Cognition and Development; Schizophrenia; Eating Behaviour; Stress; Aggression; Forensic Psychology.
AQA Psychology has a broad compulsory core, particularly in Paper 2, and Research Methods is assessed across all three papers rather than confined to one. Extended writing is central — questions worth 8, 12, and 16 marks appear regularly and require structured psychological argument.
How does Edexcel A-level Psychology work?
Edexcel A-level Psychology (specification code 9PS0) also uses three written papers at the end of Year 13.
Paper 1 (2h, 80 marks): Social Psychology and Cognition and Development. Two topic areas are covered in a single paper, with compulsory and chosen element questions.
Paper 2 (2h, 80 marks): Biological Psychology and Learning Theories. Again, two broad topic areas assessed together.
Paper 3 (2h, 80 marks): Applied Psychology. Students study areas of applied psychology — Clinical Psychology is compulsory; students then choose two from Educational Psychology, Criminological Psychology, Sport and Exercise Psychology, and Health Psychology.
Edexcel also includes a component covering research methods, which is embedded across papers rather than isolated in a single paper. Edexcel has fewer compulsory topics than AQA but a broader choice of applied option topics, and the applied focus in Paper 3 is more pronounced.
Key comparison
| Feature | AQA Psychology (7182) | Edexcel Psychology (9PS0) |
|---|---|---|
| Papers | 3 × 2h | 3 × 2h |
| Total marks | 288 | 240 |
| Compulsory core | Social influence, memory, attachment, psychopathology, approaches, biopsychology, research methods | Social psychology, cognition, biological psychology, learning theories, clinical psychology |
| Optional topics | 2 from 8 (Paper 3) | 2 from 4 applied options (Paper 3) |
| Research methods | Assessed across all three papers | Embedded throughout; specific section in each paper |
| Coursework | None | None |
| Largest question size | 16-mark essays | 20-mark essays |
| Applied psychology emphasis | Issues and debates focus | Strong applied focus in Paper 3 |
How does research methods differ between the boards?
AQA Psychology is notable for the depth of its research methods component. Quantitative and qualitative research designs, statistical tests (including the logic behind significance levels and choosing between tests), ethics, and the analysis of psychological studies are assessed across all three papers. Students on AQA need a thorough understanding of statistics and can expect a question worth 12+ marks on research methods in Paper 2.
Edexcel covers research methods across papers but with slightly less statistical depth in the written exams. Students preparing for Edexcel still need to understand core concepts — hypothesis testing, variables, reliability versus validity, different research designs — but the breadth of statistical knowledge required is slightly narrower.
Which board suits which student?
AQA Psychology suits students who want a broad conceptual foundation — learning the classic studies and theories across memory, social influence, attachment, and approaches — alongside a rigorous research methods grounding. The eight optional topics in Paper 3 offer genuine breadth.
Edexcel Psychology suits students who are more interested in applied psychology — particularly clinical and criminological contexts — and who want to see psychology put to practical use. The Paper 3 applied focus gives the qualification a real-world relevance that some students find more engaging.
Frequently asked questions
Do psychology degrees prefer one A-level board over another?
No. Psychology departments at UK universities do not specify a preferred A-level Psychology board. They look at the grade, the personal statement, and sometimes the quality of reasoning demonstrated through interview. Both AQA and Edexcel are fully recognised by UCAS and universities.
Is AQA or Edexcel A-level Psychology easier?
Neither is consistently easier. The mark allocations differ slightly (AQA papers carry more marks and include larger essays), but grade boundaries are adjusted each year under Ofqual's comparable outcomes system. The board that suits a student best depends on their strengths — students who excel at essay writing and statistical understanding often do well on AQA; those who prefer applied contexts and shorter analytical questions may find Edexcel a better fit.
Is the extended essay very different between the two boards?
Both boards include long-answer questions that require structured psychological writing. AQA uses 16-mark essays; Edexcel uses 20-mark questions. Both reward students who can describe a theory or study accurately, apply it to the question context, evaluate its limitations, and reach a reasoned conclusion. The structure — describe, apply, evaluate — is the same regardless of board, and practising this structure with past papers and mark schemes is the best preparation.
Can I study A-level Psychology without having studied it at GCSE?
Yes. There is no GCSE Psychology prerequisite for A-level Psychology at either AQA or Edexcel. Students who have studied GCSE Biology, Sociology, or History sometimes find elements of the A-level more familiar, but the specifications are self-contained and begin with foundational concepts accessible to any student with a good work ethic and genuine curiosity about human behaviour.
