How to Write an Evaluation: Criteria, Evidence and Judgement

An evaluation makes a reasoned judgement about something using clear criteria and evidence. It goes beyond describing what happened. The reader needs to understand what you judged, which standards you used and why the evidence supports your conclusion.

Define what you are evaluating

Identify the object, context and scope: a policy, project, text or intervention may need different standards. Turn the brief into a focused evaluative question. Avoid beginning with a broad opinion that leaves the reader guessing what counts as success. Explain any boundaries, such as the period examined or the group whose experience you are considering.

Choose defensible criteria

Criteria might include effectiveness, relevance, feasibility, fairness or consistency, depending on the task. Explain why each one matters. If criteria compete, discuss the trade-off rather than assuming a single score can settle it. Do not quietly change your standards halfway through the essay because one piece of evidence is difficult to accommodate.

Use evidence to support each judgement

Organise the body around the criteria or major findings. For each point, supply relevant evidence, explain its significance and state what it can establish. Distinguish a claim made by the organisation from an independently verified outcome. Where evidence is incomplete, qualify the judgement and identify the information that would help resolve the uncertainty.

Balance strengths and limitations

A balanced evaluation does not require equal numbers of positive and negative comments. It requires fair treatment of the evidence. Explain why a limitation matters and whether it changes the overall judgement. A minor presentation problem and a major failure to meet the purpose should not receive identical weight merely to make a symmetrical list.

Conclude with the judgement you established

Return to the question and draw together the most important criteria. Explain any conditions under which your conclusion holds. If the task asks for recommendations, make them follow from the evaluation. Review your draft for unsupported judgement words: “effective”, “poor” and “successful” need reasons, not just confident phrasing.

Frequently Asked Question

Description explains what something is or does; evaluation judges it against stated criteria using evidence.

No. It should weigh relevant strengths and limitations fairly.
