Understanding Exam Command Words: What GCSE and A-Level Questions Are Really Asking For

Lose marks on a GCSE or A-Level exam and it's rarely because you didn't know the content. More often, it's because you answered a different question to the one that was actually asked. The gap between "explain" and "evaluate" can be worth several marks per question — and across a whole paper, that adds up to a grade boundary.

Command words are the instructions examiners use to tell you exactly what kind of answer they want. Learn to read them properly and you'll stop writing lovely, detailed answers that quietly miss the point.

Why Command Words Matter More Than You Think

Every exam board publishes a glossary of command words, and every mark scheme is built around them. Examiners aren't marking how much you know — they're marking whether you did what the command word asked. A student who writes a beautifully detailed description when the question said evaluate can walk away with half marks, even though every fact in their answer was correct.

Examiner reports (published after every series by AQA, Edexcel, OCR and the other boards) say the same thing year after year: the most common reason for lost marks isn't factual error, it's answering the wrong type of question. That's a fixable problem, and it's one of the highest-value things you can revise, because the same command words appear across every subject and every paper.

The Command Words You'll Actually See

Different boards use slightly different wording, but almost every command word you'll meet falls into one of these groups.

Words that want you to show knowledge

• State / Identify / Name – give a fact, no explanation needed. Usually worth 1 mark.
• Describe – give a detailed account of what something is or what happened. No reasons required, just accuracy and detail.
• Outline / Summarise – give the main points briefly, without going into deep explanation.

Words that want you to show understanding

• Explain – give reasons or causes. This is the "why" or "how" word. If a question says "explain why", every point needs a "because".
• Suggest – often used when there's no single correct answer; you're expected to apply your knowledge to a new or unfamiliar situation.
• Apply – use a concept or formula in a specific context, usually in maths and science.

Words that want you to reason and weigh things up

• Compare – identify similarities and differences between two things. A list of two separate descriptions is not a comparison; you need explicit linking words like "whereas" or "similarly".
• Analyse – break something down into its parts and explain how they relate to each other or contribute to a bigger picture.
• Evaluate / Assess / To what extent – the highest-demand command words. You need to weigh up evidence or arguments on more than one side and reach a supported judgement. An evaluate answer with no conclusion is an incomplete evaluate answer, whatever else is in it.
• Justify – give reasons to support a decision or viewpoint, usually after you've already made a choice or claim.
• Discuss – consider different aspects of an issue, similar to evaluate but sometimes without requiring a final judgement – check your specification, because this varies by board and subject.

How Command Words Map to Marks

Command words aren't random wording choices — they're tied directly to Assessment Objectives (AOs), which is exam-board language for the different skills a qualification is testing. Broadly:

• AO1 (knowledge and understanding) is tested by state, describe, and outline.
• AO2 (application) is tested by explain, apply, and suggest.
• AO3 (analysis and evaluation) is tested by analyse, evaluate, compare, and discuss.

Higher-tariff questions — the ones worth 6, 8, 9, or more marks — almost always use an AO3 command word, because that's where the top mark bands live. This is exactly why past papers are so valuable for revision: they show you which command words your specification favours for its biggest questions, so you know which skill to practise most.

A Simple System for Answering Any Command Word

1. Underline the command word the moment you read the question. Do this before you underline anything else.
2. Check the mark allocation. A 2-mark "describe" needs two clear points; a 9-mark "evaluate" needs a developed argument on both sides plus a conclusion.
3. Match your structure to the word. Explain answers should read as a chain of "point → because → which means". Evaluate answers should read as "on one hand … on the other hand … overall, I think … because …".
4. Finish evaluate and assess questions with an explicit judgement. Don't make the examiner guess your conclusion — state it in the final sentence.

Common Mistakes Students Make

The same handful of errors show up across almost every subject:

• Writing a description when the question asked for an explanation (no "because" in sight).
• Comparing two things by describing them one after another instead of linking them directly.
• Evaluating without reaching a final judgement, so the answer trails off instead of concluding.
• Spending five minutes on a 2-mark "state" question and running out of time for the 9-mark "evaluate" at the end of the paper.

FAQs

Do command words mean the same thing in every subject?
Mostly, but not always — "analyse" in English Literature (looking at how a writer creates effects) is applied slightly differently to "analyse" in Geography (breaking down data or processes). Always check your specification's own command word glossary, which your teacher or exam board website can provide.

Is it worth memorising the command word list?
Yes. It takes under an hour to learn the meaning of the dozen or so words you'll actually meet, and it's one of the fastest, highest-return things you can do before exam season.

How do I get better at "evaluate" questions specifically?
Practise using past papers and mark schemes, and read a few examiner reports for your subject — they're free on exam board websites and show real examples of strong and weak evaluate answers.

What if a question doesn't use one of these words at all?
Some questions use phrasing like "how far do you agree" or "in what ways" instead of a single command word. Treat these the same as evaluate or discuss questions: they want a balanced argument with a conclusion.

Command words are one of the simplest, most overlooked ways to pick up extra marks — and at RevisionLab, we build revision resources that train students to spot exactly what a question is asking before they start writing.
