Exam Command Words Decoded: What Each Verb Demands
Exam command words determine the structure of a correct answer before you write a single sentence. The most common reason a well-prepared student scores below their knowledge level on a timed essay is not that they lacked content; it is that they answered the topic rather than the verb. A student who writes a detailed description when asked to evaluate has answered a different question, and the marks for evaluation go unclaimed regardless of how accurate the description is.
Why Command Words Cost Marks
Command words sit at the root of every exam essay question. They specify the cognitive operation the marker needs to award marks for analysis, evaluation, or judgment. Students who treat them as decoration and write whatever they know about the topic produce answers that satisfy low-order criteria but miss the higher-order marks entirely.
The Wrong-Verb Trap
The wrong-verb trap activates because exam preparation builds content knowledge, not command-word recognition. Students spend weeks learning what happened, what a theory argues, or what a mechanism does. The exam then asks them to evaluate it, and the default response draws on what they practiced: description and explanation. That mismatch produces answers that feel thorough to the student but read as lower-order to the marker.
Universities including UNSW Sydney and institutions accredited by the Quality Assurance Agency (QAA) publish explicit guidance on command words in their assessment frameworks, and those frameworks consistently show that "evaluate" and "critically analyse" sit above "describe" and "explain" in the marking hierarchy. The cognitive levels underlying this hierarchy trace back to Bloom's Taxonomyas documented by Vanderbilt University's Center for Teaching. The marks allocated to those higher-order operations do not transfer to lower-order responses.
Writing a detailed description when the command word is evaluate or critically analyse is the single most common cause of a mark that feels unfair to the student but is technically correct. The content may be accurate; the intellectual operation was not performed.
How Markers Use Command Words
Marking rubrics at most universities align bands directly to command-word compliance. A first-class or distinction response to an "evaluate" question shows evidence of evaluation in every body paragraph: a judgment, the evidence supporting it, and a weighing of counter-evidence. A passing response often contains the same facts but presents them without judgment. The difference is not knowledge; it is intellectual operation.
This means a student who understands the material completely but ignores the command word will score in the middle of the range. A student who understands less but answers the command word precisely will often outscore them, because the marking rubric rewards the operation the question specified.
The Eight Command Words Decoded
The verbs below cover the full range of command words used across university exams in humanities, social sciences, sciences, and professional disciplines. Not every exam uses all eight, but the distinction between them remains the same regardless of subject.
Describe and Explain
Describe asks for a clear, accurate account of what something is, looks like, or does. No interpretation, no judgment, no mechanism. "Describe the symptoms of X" wants the symptoms listed accurately. Describing when the question asks for something higher-order earns only the marks for that lower level.
Explain adds the mechanism. "Explain why X occurs" requires the cause-and-effect chain, not just what happens. A strong explanation names the process, the conditions that trigger it, and the consequence. Listing facts without connecting them causally answers "describe," not "explain." The distinction shows up most clearly in science and social science exams, where the mechanism is the whole point.
Analyse and Critically Analyse
Analyse asks you to break a topic, argument, or phenomenon into its constituent parts and show how each part contributes to or shapes the whole. The endpoint of analysis is insight: a statement about a pattern, a relationship, or a mechanism that was not visible before the breakdown. An answer that only lists the parts without explaining their relationship has described, not analysed.
Critically analyse adds a layer of evaluation to the analysis. You break the subject into its parts, examine how each works, and then assess the strength, validity, or significance of each part. The "critically" does not mean negative; it means systematic examination followed by reasoned judgment. A critically analytical answer might conclude that one component of an argument is well-supported while another rests on a contested assumption.
The word "critically" in any command word (critically analyse, critically evaluate, critically discuss) signals that a verdict is required. The answer must end with a reasoned judgment, not simply a balanced presentation of evidence.
Evaluate and Critically Evaluate
Evaluate asks you to make a judgment about the merit, significance, validity, or usefulness of something, supported by evidence. An evaluation requires you to commit to a position. "X is more significant than Y because of Z" is an evaluation. "There are arguments for X and arguments for Y" is a discussion, not an evaluation. The marker needs a verdict.
Critically evaluate requires the same judgment but with systematic examination of the evidence on both sides before delivering it. The process: identify the strongest arguments for the position, identify the strongest objections or limitations, weigh them against each other, and produce a verdict that reflects that weighing. This is the highest cognitive demand in most university marking rubrics, and it earns the highest marks when done well.
Discuss, Compare, and Justify
Discuss asks you to present and weigh multiple perspectives. A strong discussion names the main positions, provides evidence for each, and delivers a conclusion that indicates which position is better supported or more significant. Students who treat "discuss" as an invitation to write everything they know without taking a position typically land in the middle of the mark range. The discussion still needs a verdict, even if tentative.
Compare asks you to identify both similarities and differences between two or more things and explain their significance. The comparison must be integrated: each point of similarity or difference should appear in the same paragraph or section for both items, not in two separate halves that the reader must mentally link. "Compare" does not mean list X then list Y separately.
Justify asks you to provide reasons and evidence supporting a given position or decision. The position is usually specified in the question. Your job is to build the strongest possible case for it, address the most significant counter-argument, and explain why your evidence wins. Justification that ignores counter-arguments reads as advocacy without rigour.
Command Word Quick-Reference Table
The table below maps each command word to its specific demand, what it does not ask for, and where it sits in the cognitive hierarchy. Use it as a pre-exam reference by testing yourself: cover the right two columns and state the demand from the command word alone.
| Command word | What it demands | What it does NOT want | Hierarchy level |
|---|---|---|---|
| Describe | A clear, accurate account of features, characteristics, or events | Interpretation, judgment, or mechanism explanation | Level 1 (lowest) |
| Outline | A concise summary of main points or stages, without detail | Full explanation or analysis of each point | Level 1 |
| Explain | Show how or why something happens; clarify the mechanism or cause | Merely naming what happened without the causal chain | Level 2 |
| Analyse | Break into parts; show how each part contributes to or shapes the whole | Listing parts without explaining their relationships | Level 3 |
| Critically analyse | Analyse AND judge the strengths and limitations of each part | Analysis without any evaluative verdict | Level 4 |
| Compare | Identify similarities AND differences; explain their significance | Treating each item in isolation without integration | Level 3 |
| Discuss | Present multiple perspectives; weigh them; reach a conclusion | One-sided argument or pure description of each view | Level 3 |
| Evaluate | Judge the merit, significance, or validity of something with evidence | Balanced description without a final verdict | Level 4 |
| Critically evaluate | Systematic evaluation: examine evidence, weigh counter-arguments, deliver reasoned verdict | Evaluation without systematic examination of limitations | Level 5 (highest) |
| Justify | Provide reasons and evidence supporting a specified position; address counter-arguments | Simply restating the position without reasoning | Level 3-4 |

Strong Response Sentence Examples
The difference between a command-word-compliant response and a non-compliant one shows most clearly at the sentence level. The examples below show the first sentence of a strong response to each of the three most commonly tested command words. The first sentence determines whether the marker reads on expecting analysis, evaluation, or description.
Analyse: A Strong Opening Sentence
A strong first sentence for an "analyse" question names the parts being examined and signals the relationship the analysis will reveal.
Question: Analyse the factors that led to the 2008 financial crisis.
Strong opening: "The 2008 financial crisis resulted from the interaction of three mutually reinforcing factors: regulatory failure, excessive debt in financial instruments, and the assumption of perpetually rising housing prices; each factor amplified the others in ways that made the crisis both predictable in mechanism and underestimated in scale."
This sentence names the parts, signals their relationship (mutual reinforcement), and promises insight into mechanism. It does not describe what happened; it analyses how the parts interacted.
Evaluate: A Strong Opening Sentence
A strong first sentence for an "evaluate" question commits immediately to a verdict, then states the basis for it.
Question: Evaluate the effectiveness of monetary policy in controlling inflation.
Strong opening: "Monetary policy is an effective tool for controlling demand-pull inflation when applied with sufficient speed and credibility, but its effectiveness reduces substantially in supply-side inflationary environments, where the mechanism transmits poorly to the underlying cost pressures."
This sentence delivers a conditional verdict in the first clause and a counter-condition in the second. It does not wait until the conclusion to evaluate. The marker knows from line one that this answer will evaluate, not merely describe or analyse.
Discuss: A Strong Opening Sentence
A strong first sentence for a "discuss" question signals that multiple perspectives will be weighed and that the essay will reach a conclusion, not merely present positions.
Question: Discuss whether social media has had a net positive effect on political participation.
Strong opening: "Social media has demonstrably increased access to political information and lowered the cost of organising collective action, but these gains are offset by documented increases in polarisation and the amplification of misinformation, making the net effect dependent on which populations and which forms of participation are being measured."
This sentence acknowledges the strongest argument on each side and immediately signals that the conclusion will be nuanced rather than one-sided. It sets up a genuine discussion rather than a biased argument dressed as one.
How to Use Command Words in an Exam
Knowing what each command word demands is necessary but not sufficient. The skill is applying that knowledge under time pressure, before the blank page and the clock start pulling you toward default content-dump mode.
Decode Before You Plan
Before you write a single word of a plan or an answer, circle the command word in the question. Then write one sentence on your plan sheet stating what intellectual operation the question requires. "Evaluate: need a verdict on effectiveness with evidence for and against." That sentence costs 15 seconds and prevents you from planning a description when an evaluation was asked for.
Circle the command word
Read the question fully, then go back and circle the verb. If there are two command words ("compare and contrast," "analyse and evaluate"), circle both and treat each as a separate task.
Write the required operation on your plan sheet
One sentence: "This question asks me to [operation] by [brief statement of what the answer must do]." This takes 15 to 20 seconds and anchors every planning decision that follows.
Filter your brain-dump by the command word
When sorting your brain-dump points, cross out any point that serves the topic but not the command word. An "evaluate" question does not need the historical background that would open a "describe" answer.
Check each paragraph topic sentence against the command word
Each body paragraph should deliver the operation the command word specified. An evaluate paragraph ends with a judgment. An analyse paragraph ends with an insight about relationship or pattern.
Re-read the question in the final two minutes
Before writing your conclusion, re-read the question. Confirm that the body of your answer performed the specified operation and that your conclusion delivers the verdict, insight, or position the command word required.
Matching Paragraph Structure to the Verb
Each command word maps to a slightly different paragraph closing sentence. The opening of a body paragraph can look similar across command words; the close is where compliance shows.
| Command word | Closing sentence pattern for a body paragraph |
|---|---|
| Analyse | "This reveals that [relationship/pattern/mechanism]..." |
| Evaluate | "This suggests that [verdict], though [main limitation or counter-evidence]..." |
| Critically evaluate | "On balance, [position] because [strongest evidence], but this conclusion rests on [key assumption that could be challenged]..." |
| Discuss | "The weight of evidence therefore favours [position], because [key reason]..." |
| Compare | "This similarity/difference is significant because [implication for the question]..." |
| Justify | "This evidence therefore supports [position] because [reason], despite the counter-argument that [objection]..." |
Closing sentence patterns that signal compliance with the command word. These endings deliver the intellectual operation the question specified.

Key Takeaways
- Command words specify the intellectual operation required, not just the topic. Misreading the verb costs marks regardless of content quality, because marks for higher-order operations do not transfer to lower-order responses.
- Describe and explain sit at the base of the cognitive hierarchy. Analyse, evaluate, and critically evaluate sit at the top. Moving down the hierarchy when a higher-order verb was asked produces an accurate but insufficiently demanding response.
- Evaluate and critically evaluate require a verdict: a judgment about merit, significance, or validity supported by evidence. Presenting evidence on both sides without delivering a verdict answers "discuss," not "evaluate."
- Critically analyse and critically evaluate both require systematic examination followed by a reasoned judgment. The word "critically" signals that a verdict is required, not a balanced summary.
- Before planning, circle the command word and write one sentence stating the required operation. This 15-second investment prevents the plan from drifting toward the wrong intellectual mode.
- Each body paragraph closing sentence should deliver the operation the command word specified: an insight for "analyse," a judgment for "evaluate," a weighted conclusion for "discuss."
- Practice command-word recognition by taking past questions and writing only the thesis sentence and required operation for each, without writing the full answer. This builds fast recognition that transfers to the exam under pressure.
