Short answer: how to answer 16 mark psychology questions comes down to one fact: most of the marks are for evaluation, not description. In AQA's specimen mark scheme, a "discuss" or "describe and evaluate" essay gives 6 marks for knowledge (AO1) and 10 for evaluation (AO3). With a scenario, it becomes 6 AO1, 4 AO2 and 6 AO3 [3]. So keep description brief and build three or four developed evaluation points.
Where the 16-mark questions sit
AQA A-Level Psychology (7182) has three papers. Each lasts 2 hours, carries 96 marks and is worth one third of the A-level. Every section mixes multiple choice, short answers and extended writing [1]. In AQA's specimen Paper 1, the longest of these are worth 16 marks [3].
AQA updated the course content for first teaching in September 2025. The first A-level exams on it are in June 2027. AQA states that paper design, question types and paper structure are unchanged [5]. So the 16-mark technique below works on the updated course. One example: depression is still on the spec, under the new heading Clinical Psychology and Mental Health [6].
How the 16 marks are split
AQA marks three assessment objectives (AOs), the skills the exam board rewards [2]. AO1 is knowledge and understanding. AO2 is applying that knowledge to a context. AO3 is analysing and evaluating, including making judgements.
AQA's guidance for teachers says a 16-mark question carries at most 6 AO1 marks, with the other 10 shared between AO2 and AO3 [4]. The specimen mark scheme for Paper 1 shows the two usual patterns [3]:
| Question type | AO1 Knowledge | AO2 Application | AO3 Evaluation |
|---|---|---|---|
| No scenario ("discuss", "describe and evaluate") | 6 | 0 | 10 |
| With a scenario you must refer to | 6 | 4 | 6 |
When there is a scenario, evaluation drops from 10 marks to 6, and 4 marks move to application. AQA's guidance warns that an answer which ignores the scenario faces a maximum mark [4]. So link the scenario to theory in your description and at least one evaluation point. Say a student in the scenario thinks "I failed one test, so I am useless and always will be". Name that as Beck's negative view of the self and the future.
Examiners mark the whole answer against four levels. In our words, the top level (13–16 marks) needs precise, detailed knowledge and thorough, effective evaluation. The answer must stay on the question and use psychological terms well [3].
How to answer 16 mark psychology questions: a five-part structure
AQA says there is no set number of evaluation points [4]. Our advice is three or four, each fully developed. Depth earns more than a long list.
- Brief AO1 (about 150 words). Describe the theory accurately with key terms. Do not write everything you know: only 6 marks are available.
- AO3 point one: research support. Use PEEL: Point, Evidence (a named study with its year and finding), Explain why it helps the theory, Link back to the question.
- AO3 point two: counter-evidence. A study or theory that challenges the explanation. Say what it suggests instead.
- AO3 point three: an issue or debate. Use the Paper 3 debates: nature-nurture, reductionism, determinism, or gender and cultural bias [7]. Apply it to this theory, not psychology in general.
- A short judgement. Two or three sentences that answer the question. How strong is the theory overall, and what does it explain well or badly?
A fourth AO3 point, often a practical application such as a therapy, fits in if time allows.
Timing: why about 20 minutes
Each paper gives you 120 minutes for 96 marks [1]. That is 1.25 minutes per mark, so a 16-mark question is worth about 20 minutes. Spend 2 minutes planning, about 5 on AO1 and about 13 on evaluation. If you spend 10 minutes describing, you are spending half your time on 6 of the 16 marks.
A worked AO3 paragraph: the cognitive approach to depression
Depression is common. In April 2025, 18% of adults in Great Britain reported moderate to severe depressive symptoms, rising to 26% of those aged 16 to 29 [8]. These are self-reported symptoms from a survey, not clinical diagnoses.
Practice question, in our own words: Discuss the cognitive approach to explaining depression. [16 marks] Your AO1 would outline Beck's (1967) negative triad and Ellis's (1962) ABC model. Here is one AO3 paragraph.
Point: A strength of the cognitive explanation is support from prospective research.
Evidence: Cohen et al. (2019) followed 473 school students for three years, interviewing them every six months. Two thinking styles measured at the start predicted later episodes of depression: rumination (dwelling on negative feelings) and a negative attributional style (explaining bad events in negative ways). This held even after taking account of symptoms at the start [9].
Explain: Because the thinking styles were measured before the episodes, faulty thinking seems to come before depression, not only after it. This supports Beck's claim that negative thoughts help cause depression.
Counter-evidence: However, Sullivan et al. (2000) combined twin studies and estimated that about 37% of the risk of major depression is genetic [10]. So the cognitive approach is reductionist if it treats thinking as the only cause, and negative thinking styles may themselves be partly inherited.
Link: An interactionist view fits the evidence better: faulty thinking raises risk, but alongside genes and life events. So the cognitive approach explains part of why depression starts, not all of it.
Notice the structure. The study is named, dated and described accurately. The paragraph explains why the evidence matters, then tests it with counter-evidence and a debate. It ends with a judgement on the question, not a summary.
Common mistakes
- Too much description. AO1 is capped at 6 marks [4]. Extra description earns nothing.
- A list of thin evaluation points. "Supported by research" with no study named is not effective evaluation. Name, date and explain.
- Ignoring the scenario. On a scenario question, no reference to it means a capped mark [4].
- Generic issues and debates. "It is deterministic" earns little unless you explain why for this theory.
- Revising removed content. If you use older notes, check the current spec. Biological rhythms, for example, are no longer in the Biopsychology content [11].
- Running over time. Stop at about 20 minutes, so you do not lose easier marks later in the paper.
