Explain, Analyse or Evaluate? How to Read HSC Exam Questions

In HSC questions, explain usually asks you to make the why or how clear, analyse asks you to examine relationships and implications, and evaluate calls for a judgement using relevant criteria. The exact response still depends on the subject and the rest of the question.

The task word gives you a direction. To choose the right content, you also need to notice the topic boundaries, any supplied material and what the question specifically asks you to do with it.

Read the whole instruction before reaching for your notes

Try separating a practice question into three parts:

• The action: explain, analyse, evaluate or another instruction.

• The focus: the process, period, concept or issue being examined.

• The conditions: a named source, a particular example, a time period or a required comparison.

For example, a question about the usefulness of a source for investigating one event is narrower than a question about everything the source reveals. A detailed response about the wrong event still misses the task.

As a final check before writing, finish this sentence to yourself: “My answer needs to show…” If your completion is only the name of a topic, reread the instruction.

Explain: make the connection visible

An explanation takes the reader through a reason or relationship. Simply naming a feature often leaves the important step unstated. These meanings follow NESA’s glossary of key words, which also cautions against rigid interpretations.

Consider this original practice prompt: Explain why a business needs to monitor cash flow.

“Cash flow is important for a business” repeats the premise. A more useful start connects incoming and outgoing cash to the business’s ability to pay bills when they fall due. You could then explain how monitoring the timing of those payments helps identify a possible shortfall.

The improvement comes from supplying the link. Adding the word “because” is only useful if a clear, accurate reason follows it.

Analyse: show how the parts interact

Analysis goes beyond collecting separate observations. Look for the relationship between the relevant parts and consider what follows from it.

For an original practice prompt asking you to analyse the relationship between customer service and repeat sales, you might connect how a complaint is handled with customer satisfaction and the likelihood of returning. You would also need to consider the context: price, product quality or other factors may affect that relationship.

Try drawing two arrows in your practice notes: one between the factors and another from their relationship to its consequence. Then turn those arrows into sentences. If the response is still a list of unrelated facts, the analysis needs another step.

Evaluate: tell the reader how you reached a judgement

A judgement needs a basis. For a history source, useful criteria might include its relevance to the investigation, its perspective and the limits of what it can establish. The criteria must fit the actual question.

An original practice prompt could ask: Evaluate the usefulness of a source for investigating public responses to an event. Saying “the source is biased, so it is useless” closes the discussion too quickly. A strongly partisan source might still reveal one group’s attitude. Explain what it helps establish, what it cannot show, and how that affects your overall judgement.

Mathematics uses “evaluate” differently in many questions: it can require finding a value. Subject context always matters.

Practise with the marking guidelines beside you

NESA’s preparation guidance stresses responding to the question set and using the required stimulus material. A memorised paragraph can be accurate yet poorly suited to the task.

Choose one past question relevant to your current syllabus. Write a short plan, then compare it with the official marking guidelines. Check which relationships, evidence or judgements your plan actually demonstrates. Avoid assigning yourself a mark just because you have written a certain number of paragraphs.
