GCSE command words: what exam questions are asking you to do

You read an exam question, recognise the topic and start writing. But knowing the content is only part of the task. The examiner might want a fact, a reason, a comparison or a judgement. If you give the wrong kind of response, you can miss marks even when your knowledge is sound.

That is why understanding gcse command words matters. These are the instruction words that tell you what to do with what you know. Once you can spot the difference between “describe”, “explain” and “evaluate”, questions become easier to approach. This guide covers common instructions, shows how answers change and gives you a simple routine to practise before your next exam.

What are command words in GCSE exams?

Command words are the verbs that direct your answer. You will find them across GCSE subjects, including English, maths, science, history and geography.

Consider these two questions:

“Describe the pattern shown in the graph.”

“Explain the pattern shown in the graph.”

The first asks what the graph shows. The second asks why that pattern occurs. Simply describing the graph in both answers would not meet both instructions.

Treat the command word as one part of the question. You also need to notice:

The topic you must address.
Any source, quotation, graph or data you must use.
Limits such as “give two reasons” or “refer to Figure 1”.
The number of marks available.

Exact expectations can vary between subjects and exam boards. Your specification, official command word guidance and mark schemes are the best references for your course.

Common GCSE command words and what they mean

You do not need to memorise a script for every instruction. Start by recognising the type of thinking each word usually requires.

Identify, name or state

Give the requested information directly. If asked to name an organ, provide its name rather than a paragraph about its functions.

Define

Give the precise meaning of a term. Include the features that distinguish it from similar ideas, rather than only giving an example.

Describe

Set out what something is like, what happens or what a pattern shows. Include relevant detail. For a graph, this might mean the overall trend, supporting figures and any exceptions.

Explain

Give reasons or show how something happens. Connect the point to its cause, mechanism or consequence. Words such as “because” and “therefore” can help make those links clear.

Compare

Make direct comparisons between the things named. Usually, consider both similarities and differences unless the question or subject guidance specifies otherwise. Use phrases such as “both”, “whereas” and “in contrast”.

Calculate

Work out a numerical answer. Show the relevant method and working, and include units where needed. Follow any instructions about rounding or significant figures.

Analyse

Examine details and explain their significance or relationships. In English, this could mean exploring how a writer’s language creates meaning. In another subject, it might involve interpreting patterns in evidence.

Evaluate

Assess something against relevant evidence or criteria and reach a supported judgement. Depending on the subject, you might weigh strengths, weaknesses, benefits, limitations or competing explanations.

Justify

Support a choice, claim or conclusion with reasons and evidence. Make clear why your answer is appropriate, rather than simply repeating it.

Suggest

Use your knowledge and any information provided to offer a plausible answer. This often involves applying familiar ideas to an unfamiliar situation, not making an unsupported guess.

How the instruction changes your answer

The easiest way to understand gcse command words is to apply different instructions to the same information.

Imagine a graph showing that a plant grows taller as light intensity increases, before its height levels off.

Describe the pattern

“As light intensity increases, plant height increases at first, then levels off.”

This reports what is visible. In an exam, include figures from the graph if they help make the description precise.

Explain the pattern

“Increasing light intensity can increase photosynthesis, supporting growth. Once light is no longer the limiting factor, another factor, such as carbon dioxide availability, may limit further growth.”

This gives a possible biological explanation rather than repeating the trend. The full question would determine which details are relevant.

Evaluate a conclusion based on the graph

Suppose the conclusion is: “More light always produces taller plants.” You could explain that the initial increase supports it only over part of the range. The plateau challenges the word “always”. You would then judge how far the evidence supports the claim.

The topic stays the same, but the task changes. More writing is not automatically better. The right kind of thinking matters more.

Match your answer to the marks available

The mark total helps you judge the likely depth of an answer, but it is not a universal sentence counter.

A one mark “state” question may need only a short phrase. A longer “explain” question may need several connected steps. An extended “evaluate” response may require evidence, developed reasoning and a supported judgement.

Some questions award marks for individual points. Others use levels that assess the quality of the whole response. Avoid assuming that every sentence earns one mark.

Watch for these common mistakes:

Describing instead of explaining. Check that you have answered why or how, not just what happened.
Writing two separate descriptions instead of comparing. Link the two things directly using the same feature.
Listing advantages and disadvantages without evaluating. Explain their importance and reach a judgement where required.
Quoting without analysing. Explain what the evidence shows and how it supports your point.
Giving an answer without required working. Make your mathematical method visible.

Before moving on, ask: “Have I followed the instruction, used the required information and answered the whole question?”

A simple way to practise before your exam

Learning gcse command words works best when you use them with real questions. Try this routine during revision.

First, read and label the task. Circle the command word, underline the topic and note any conditions. Check the marks before deciding how much detail to give.

Next, plan the shape of the answer. For “explain”, think in linked reasons. For “compare”, choose shared features. For “evaluate”, identify the evidence and the judgement you need to make.

Then, answer without your notes. This shows whether you can apply your knowledge independently, rather than just recognise a model answer.

Finally, check and improve. Use the official mark scheme and, where available, examiner reports. Identify whether a missed mark came from missing knowledge, unclear reasoning or misunderstanding the instruction. Rewrite the weakest part.

Keep a short record of recurring mistakes. If you regularly describe when asked to explain, make that your focus for the next practice session.

FAQ

Are GCSE command words the same in every subject?

Many appear across subjects, but their application can differ. “Analyse” in English looks different from analysing scientific data. Check guidance for your exam board and qualification, and practise with subject specific questions.

What is the difference between describe and explain?

“Describe” asks what something is like or what happens. “Explain” asks why or how. An explanation needs a clear link between a point and its reason, mechanism or consequence.

Does evaluate always mean giving both sides?

Not necessarily in equal amounts. You need to assess relevant evidence or criteria and reach a supported judgement. Follow the question rather than forcing every answer into a fixed advantages and disadvantages structure.

How much should I write for a six mark question?

There is no fixed word count. Use the command word, subject guidance and mark scheme to understand the expected depth. Aim for relevant, developed points rather than filling space or writing exactly six sentences.

What should I do if I do not recognise a command word?

Read the whole question carefully. Use the topic, supplied information and marks to work out the likely task. During revision, check unfamiliar instructions in your exam board’s guidance and ask your teacher or tutor for an example.
