How to Answer the 10-Mark "Evaluate" Question in Cambridge A Level Psychology (9990) Paper 3

A strong 10-mark evaluation explains what the psychological evidence allows you to conclude, where its limitations lie, and why those limitations matter. Identify exactly what the question asks you to evaluate, address the issue it names, and support your judgements with relevant details. Listing strengths and weaknesses without explaining their significance leaves the most useful reasoning unwritten. The challenge is that you may know a study or treatment well enough to describe it, yet struggle to evaluate it. More factual detail alone will not solve that problem. You need to use the detail to make an argument: what does this feature strengthen, what does it weaken, and how does that affect our understanding of the topic?

Understand the change from describe to evaluate

Paper 3 pairs a six-mark “Describe” part with a ten-mark “Evaluate” part in each specialist option. The evaluation is assessed through AO3, analysis and evaluation. The top level rewards developed evaluation, analysis sustained across the response, a suitable range of issues that includes the named issue, and well-chosen supporting evidence. It is therefore important to change what you do with your knowledge when moving from part (a) to part (b). Description establishes what happened or what an explanation proposes. Evaluation considers what that means for the quality, usefulness or limitations of the evidence. For example, identifying a field experiment is descriptive. Explaining how its setting makes the observed behaviour more realistic, while also considering the difficulty of controlling competing influences, develops an evaluative argument. The factual detail is still necessary, but it now supports a judgement.

Identify the exact target before choosing your points

Read the whole question before selecting evaluation points. Is the target one study, two treatments, a theory, or a pair of explanations? A memorised criticism can be accurate and still fail to address that target. Criticising one study’s sample, for example, needs a clear connection if the question asks you to evaluate the treatment it investigates. Underline the material being evaluated and the issue introduced by “including a discussion about”. Then make a brief plan of relevant evidence and its implications. If the question names two treatments, give both meaningful attention rather than writing everything about the one you remember best. The named issue should appear in your plan before you start writing, so it cannot be forgotten halfway through.

Address the named issue through the actual topic

May/June 2024 Paper 32, Question 4(b), asks students to evaluate ECT and CBT for schizophrenia, including the idiographic versus nomothetic approach. Defining those terms is only a starting point. You need to connect general principles and individual differences to the treatments being evaluated, then explain the value or limitation of that connection. For example, CBT can follow a general therapeutic approach while responding to a particular patient’s thoughts and goals. An evaluative discussion could consider how that individual focus helps address different experiences, alongside the challenge of comparing outcomes when treatment is adapted. Avoid reducing the argument to a label such as “CBT is idiographic, so it is good”. Identify the relevant feature and explain what follows from it.

The screenshot suggests two strengths and two weaknesses as one possible strategy. Treat that as an optional planning aid. Cambridge’s levels descriptors do not prescribe that paragraph count or balance.

Turn a study detail into an evaluative explanation

May/June 2024 Paper 32, Question 8(b), asks students to evaluate North et al.’s study of musical style and restaurant spending, including ecological validity. This gives you a specific task: explain how realistically the study captures the behaviour it investigates, using details from the research rather than a definition alone. An original NeuraGeek example of a weak point is: “The study has high ecological validity because it took place in a restaurant.” A developed version is: “Customers made real purchases in a working restaurant, where background music was part of the dining environment. Their spending therefore reflects a meaningful consumer decision rather than a hypothetical choice in a laboratory. This supports the relevance of the findings to similar dining situations.” The additional sentences explain why the setting matters.

That does not establish that the findings apply to every restaurant or customer. A realistic setting and broad generalisability are different questions. Keep the conclusion proportionate to the evidence.

Develop a range without collecting empty labels

A response needs more than repeated versions of the same criticism. If every paragraph says the study cannot be generalised, changing the example does not necessarily broaden the evaluation. Select issues that reveal different strengths or limitations and that you can explain accurately. Depending on the question, these might concern evidence quality, practical usefulness, ethics, competing explanations or a relevant debate. Use a simple planning sequence: make a judgement, identify the supporting detail, and explain its consequence. This is a study technique rather than a required paragraph formula. A point about sample composition should explain whose behaviour may be represented less well. A point about measurement should explain what the measure captures or misses. A point about practical use should identify who could use the finding and under what circumstances. It is also useful to distinguish related terms. Reliability concerns consistency; validity concerns whether the method or interpretation captures what it claims to. A numerical measure does not automatically make an entire study valid, and a realistic setting does not remove every possible confounding influence. Choose the term that matches the argument you are actually making.

Keep analysis running through the answer

Do not save all your reasoning for a concluding sentence. After each piece of evidence, explain its significance before moving to the next point. Words such as “therefore”, “because” and “however” can help you make a connection, but the connection itself must be convincing. Adding “therefore it is useful” without explaining the use does not develop the point. A counterpoint can make an argument more precise. An individualised approach may respond closely to a person’s circumstances, while making standardised comparisons more difficult. A realistic research setting may capture everyday behaviour, while giving researchers less control over other influences. Neither trade-off should become a memorised verdict. Explain which feature of the particular study or approach creates it and how far it affects your conclusion.

Use the ending to answer the evaluation

If you include a concluding judgement, make it follow from the discussion rather than simply repeating that there are strengths and weaknesses. State what the evidence supports and the main condition or limitation on that conclusion. Do not introduce a new study in the final sentence that you have no space to explain. The ending should bring together reasoning already developed throughout the answer.

Review the reasoning before practising again

Before finishing, check that you have evaluated the exact material named, addressed the specified issue, used accurate supporting details and explained their implications. Look for paragraphs that only retell the study, repeat an earlier criticism, or label something a strength without explaining why. Also check that any numerical detail or research finding is something you can support rather than a half-remembered addition. In NeuraGeek, open a Psychology Paper 3 question and attempt the ten-mark response before asking for help. Use the Paper tutor to unpack an issue you find difficult, or submit your attempted answer through Examiner mode for feedback. Then revise the weakest paragraph and try another question independently. Aim to improve the link between evidence and judgement, so your next answer makes its evaluation clear without needing the tutor to supply it.
