Edexcel Command Words Explained: Complete A-Level Guide

You've read the question. You know the topic. But if you don't understand what the command word is actually asking you to do, you'll lose marks — even with the right knowledge.

Edexcel examiners use specific command words to signal exactly what type of answer they want. Students who understand these words structure their answers correctly. Students who don't often write the right content in the wrong format and walk away with half the marks they deserved.

This guide covers every Edexcel A-Level command word — what each one means, how to structure your answer, and how the expectations shift as you move from GCSE into A-Level study.

What Are Command Words?

Command words are the instruction words at the start of an exam question. They tell you:

• What to do (analyse, evaluate, discuss)
• How much depth is expected (state vs. explain vs. assess)
• What the mark scheme is looking for (judgement, evidence, both sides)

Edexcel uses the same core command words across subjects — Business, Science, Geography, Psychology, Biology, Physics, and others — with the same fundamental expectations at each level. Miss the command word, and you miss the mark allocation.

The Complete Edexcel Command Word Guide

State / Identify / Give / Name

What Edexcel wants: A simple, direct answer. No explanation needed.

Mark allocation: Usually 1 mark per point.

Example question: "State two factors that affect price elasticity of demand."

Correct approach:

• Factor 1: The availability of substitutes
• Factor 2: The proportion of income spent on the good

Common mistake: Writing a full paragraph when one line is enough. You don't gain marks for extra explanation — and you waste time.

Define

What Edexcel wants: A precise, accurate definition of a term. Often includes context.

Mark allocation: 2–3 marks typically.

Example question: "Define the term 'market failure'."

Correct approach: State the definition clearly in one or two sentences. Use subject-specific vocabulary. Do not add examples unless the mark scheme requires them.

Pro tip: Learn exact definitions for key terms in your subject. Vague or approximate definitions often only pick up 1 of the available marks.

Describe

What Edexcel wants: An account of the main features or characteristics. Show understanding, but no analysis or judgement required.

Mark allocation: 2–4 marks.

Example question: "Describe how a business might respond to a rise in interest rates."

Correct approach: Outline what happens step by step or list the key features clearly. Include relevant detail, but stay factual — don't offer opinions or evaluate.

Explain

What Edexcel wants: Show understanding and provide reasoning. Don't just say what — say why or how.

Mark allocation: 3–6 marks.

Example question: "Explain why a fall in consumer confidence might reduce GDP."

Correct approach: Make a point, then develop it with reasoning. Use connective phrases like:

• "This means that..."
• "As a result..."
• "This is because..."

Formula: Point → Link → Explanation

Common mistake: Describing when you should be explaining. "Consumer confidence fell" is description. "When consumer confidence falls, households reduce discretionary spending, which lowers aggregate demand and therefore GDP" is explanation.

Analyse

What Edexcel wants: Break down the topic, show how different parts connect, and develop a chain of reasoning. More depth than explain.

Mark allocation: 6–10 marks.

Example question: "Analyse the impact of a rise in the minimum wage on a labour-intensive business."

Correct approach:

1. Identify the key effects (cost of labour rises)
2. Develop the chain of reasoning (higher costs → reduced profit margin → potential redundancies or price rises)
3. Show how factors connect (the impact depends on whether the firm is price-sensitive or labour-flexible)

Key rule: Develop your point further than you think is necessary. Examiners want to see chains of reasoning — not just an initial observation.

Assess

What Edexcel wants: Weigh up evidence and reach a supported judgement. Consider multiple factors, acknowledge limitations, then conclude.

Mark allocation: 8–15 marks.

Example question: "Assess the view that a business should always prioritise profit maximisation."

Correct approach:

1. Arguments for the view (with evidence/reasoning)
2. Arguments against (or limitations/counter-arguments)
3. A clear conclusion — which factors carry most weight, and why

What separates top marks: The quality of your conclusion. A good conclusion doesn't sit on the fence — it makes a supported judgement based on the evidence you've presented.

Evaluate

What Edexcel wants: Similar to assess, but usually applied to a specific argument or policy. Judge the strengths and limitations. Reach a verdict.

Mark allocation: 12–20 marks (often in extended question formats).

Example question: "Evaluate the effectiveness of fiscal policy as a tool for managing demand."

Correct approach:

1. Explain the mechanism (how it works in theory)
2. Examine the evidence (when has it worked / when has it failed?)
3. Consider limitations (time lags, political constraints, crowding out)
4. Conclude with a clear, justified verdict

Critical difference from analyse: Evaluate requires a verdict. Don't just build the argument — judge it.

Discuss

What Edexcel wants: Present different perspectives or arguments on a topic. More balanced than evaluate — you're exploring the debate rather than reaching a definitive verdict.

Mark allocation: 8–15 marks.

Example question: "Discuss the advantages and disadvantages of a floating exchange rate for an economy."

Correct approach:

• Advantages: [developed points]
• Disadvantages: [developed points]
• Brief concluding comment (which side carries more weight, or "it depends on...")

Note: Some Edexcel mark schemes treat "discuss" and "evaluate" similarly at A-Level. Always check subject-specific marking guidance.

Calculate

What Edexcel wants: Use the given data to produce a numerical answer. Show your working.

Mark allocation: 1–4 marks. Often method marks available even if final answer is wrong.

Example question: "Calculate the price elasticity of demand given the following data."

Critical rule: Always show your working. If your final answer is wrong but your method is correct, you can still pick up method marks. No working = no method marks.

To What Extent

What Edexcel wants: Make a judgment about how much something is true, effective, or significant. Similar to evaluate but explicitly requires a degree judgment.

Mark allocation: 15–25 marks (typically top-mark extended questions).

Example question: "To what extent is marketing the most important factor in a business's success?"

Correct approach:

1. Case for (marketing is the most important — developed arguments)
2. Counter-case (other factors — quality, finance, HR — may be equally or more important)
3. Conclusion that takes a clear position on the extent: "Marketing is highly significant, but its importance is contingent on..."

What examiners want to see: Your ability to make and defend a nuanced position. Don't conclude with "it depends" without explaining what it depends on and why.

Edexcel A-Level Command Words: Quick Reference

Moving from GCSE to Edexcel A-Level: What Changes?

The command words are the same — but the expectations escalate sharply. The most common Year 12 trap is answering A-Level questions at GCSE depth: technically correct answers that miss the mark because they don't go far enough.

The key adjustment: At A-Level, "explain" in a 6-mark question needs a full chain of reasoning — not just a point and one development. Students who carry over GCSE habits often score 3–4 out of 6, technically correct but structurally too shallow for the A-Level mark scheme.

Edexcel Command Words by Subject

The core command words mean the same thing across subjects, but how you apply them differs. Here's what examiners look for in the most searched Edexcel A-Level subjects.

Science (A-Level)

Edexcel Science command words carry specific expectations tied to practical and experimental contexts:

• Describe — in Science, this often means describing a trend in data, a graph, or an experimental method. State what you observe (including values), not what it means.
• Explain — in Science, linking the observation to the underlying scientific principle. "Explain why the rate of reaction increases with temperature." → Collision theory, activation energy, frequency of successful collisions.
• Evaluate — often applies to experimental methods in Science: evaluate a procedure, suggest improvements, consider limitations.
• Calculate — follow the formula, show working, include units. Method marks are always available in Science.

Biology-specific note (A-Level): Edexcel A-Level Biology uses "evaluate" heavily for data interpretation questions. Practice interpreting graphs and tables as part of command word revision, not just content recall.

Geography (A-Level)

Edexcel Geography has a strong emphasis on case studies and located examples. Command words in Geography nearly always expect geographical context in the answer:

• Describe — describe a geographical pattern, trend, or distribution using named evidence. Reference specific locations, statistics, or case studies.
• Explain — link the geographical pattern to a process or cause. "Explain why coastal erosion rates vary." → Geology, wave energy, fetch, human factors — with development.
• Assess / Evaluate — Geography uses these for extended responses about case studies or policies. The mark scheme rewards specific named examples and located evidence.

Key Geography rule: Named examples and specific data separate good answers from average ones. Generic answers ("in some areas..." "in some countries...") cap out at mid-band marks.

Business Studies (A-Level)

Edexcel Business is heavily application-based. Command words require you to apply knowledge to a specific business context, not just recite theory:

• Explain — apply to the business in the question. Don't just explain the concept in general; reference the specific business type or scenario.
• Analyse — trace the impact through the business. Start with the immediate effect, develop the chain all the way through to consequences.
• Evaluate — reach a conclusion about the specific business. At A-Level, the business context in the question is your source of evidence. The conclusion must make a judgement in the context of this business, not businesses in general.

Physics (GCSE and iGCSE)

Edexcel Physics (including iGCSE) uses command words with precision:

• State — one line. No justification. Many students write paragraphs for 1-mark state questions in Physics; this is wasted time.
• Describe — describe a process, an observation, or a graph trend. Stay descriptive; don't explain unless asked.
• Explain — link the observation to the underlying Physics. Equations and units can strengthen explain answers.
• Calculate — show all working, including formula, substitution, and units. A final answer without working receives 0 method marks if incorrect.
• Suggest — appears when the answer isn't directly in the specification. Use your scientific knowledge to reason through an unfamiliar scenario.

iGCSE Physics note: Edexcel iGCSE Physics papers tend to use "describe and explain" as a combined command in practicals. This means: first describe what you observe, then explain the scientific reason behind it — two distinct parts, both needed for full marks.

How to Spot the Command Word Under Exam Pressure

When you sit down in the exam hall, adrenaline can make you rush to write before you've processed the question. Train yourself to do this in the first 30 seconds of reading any question:

1. Circle the command word first — physically mark it before you read anything else
2. Note the mark allocation — higher marks = deeper response required
3. Identify the topic — what subject matter is being tested?
4. Plan before you write — even 30 seconds of bullet-point planning improves structure

FAQs — Edexcel Command Words

Does Edexcel use the same command words across all A-Level subjects?

Yes — the core command words (state, explain, analyse, evaluate, assess) are consistent across Edexcel A-Level subjects. However, the depth expected and subject-specific application varies by mark scheme.

What's the difference between "analyse" and "evaluate" in Edexcel?

Analyse asks you to build a chain of reasoning — showing how parts connect. Evaluate asks you to go further: assess the strengths and limitations of something and reach a judgement. Evaluate always requires a conclusion; analyse can stop at the reasoning.

How much should I write for a "to what extent" question?

Enough to cover at least two developed perspectives and a clear conclusion. For a 20-mark question, aim for 600–900 words. Quality over quantity — two well-developed arguments beat five underdeveloped ones.

Do I need to write a conclusion for "analyse" questions?

Not always — Edexcel mark schemes for "analyse" typically reward the quality of reasoning rather than a final verdict. However, a brief concluding sentence strengthens your answer and signals that you've developed your chain of reasoning fully.

What if the question uses "explain and analyse"?

Treat it as an analyse question. The "explain" element is embedded — you need to explain to set up your analysis. Don't stop at the explanation.
