Evaluating the usefulness of a source: judging a source by its origin, purpose, timing and content, and by what a historian knows the source leaves out, to decide how useful it is as evidence.

What this dot point is asking

The "Evaluate the usefulness of a source" question is one of the source-handling skills tested across every context of SQA National 5 History. It gives you a source, often with an attribution telling you who wrote it, what it is and when, and asks how useful it is as evidence of a named issue. The skill is judgement: weighing what makes the source valuable against what limits it. Unlike Describe and Explain, this question is partly about the source in front of you, though strong answers also bring in recalled knowledge to judge what the source leaves out.

This is one of the highest-value source questions on the paper and a place where method matters more than luck. SQA marks usefulness against a clear checklist, so a candidate who works through that checklist systematically can reach the tariff on almost any source. The danger is the stock phrase: writing "it is primary so it is useful" without explaining why earns nothing.

The answer

The usefulness question rewards developed comments about a source as evidence of the named issue, built from a fixed checklist: origin, purpose, timing, content and omission, finished with a supported judgement. Origin means who produced the source and what type it is. Purpose means why it was made. Timing means when it was made, relative to the events. Content means what the source actually says that bears on the issue. Omission means what a historian knows about the issue that the source does not show. Each developed comment that links a feature to usefulness earns a mark.

Origin, purpose and timing

Start with the attribution. The origin (author and type) matters because a participant, an official, a journalist or a later historian each bring different value and limits. The purpose matters because a source made to persuade differs from one made to record. The timing matters because a source written at the time differs from one written long after. The key move is always to link the feature to the issue: not "it was written by a politician", but "it was written by a politician defending the policy, so it stresses its benefits, which limits it as a balanced view".

Content and omission

After the attribution, use the source itself. Pick out specific details in the content and say what each usefully reveals about the issue. Then weigh the other side: what relevant information, which you know from your studies, does the source not show? Naming a relevant omission, and explaining why it limits usefulness, is one of the surest marks in this question and the part candidates most often forget.

Reach a supported judgement

Finish with an overall judgement that weighs strengths against limits, rather than a bare verdict. "Overall the source is quite useful because it gives a contemporary, first-hand account, but it is limited because it shows only one side." A judgement like this, supported by the points you have made, rounds off a full-mark answer. Avoid ending on "so it is useful" with nothing behind it.

Examples in context

Suppose the source is a speech by a campaigner, given at the time, arguing for a reform, and the question asks how useful it is as evidence of why the reform was supported. A weak answer offers labels: "It is primary, so it is useful. It is biased, so it is not useful." Neither comment is linked to the issue, so the answer scores almost nothing.

A full-mark answer works the checklist: origin, "as a campaigner the speaker knew the arguments first-hand, which makes the source useful for the case for reform"; purpose, "the speech was meant to persuade, so it stresses the strongest arguments and plays down objections, limiting its balance"; timing, "it was given at the time, so it captures the contemporary mood, not later hindsight"; content, "it usefully sets out the specific hardships campaigners pointed to"; omission, "it does not show the opposing arguments, which a full picture would need"; judgement, "overall it is useful for the case for reform but one-sided".

Try this

Q1. What five things should you comment on when evaluating the usefulness of a source? [2 marks]

• What the marker wants. Origin (author and type), purpose, timing, content, and a relevant omission, each linked to the issue, followed by a supported judgement.

Q2. Why does "it is biased, so it is not useful" score poorly? [2 marks]

• What the marker wants. Because bias does not make a source useless: a biased source can be very useful as evidence of attitudes or of one side's case, so the comment must explain how the feature affects usefulness for the issue.

Q3. What is a relevant omission, and why does naming one earn a mark? [1 mark]

• What the marker wants. Something a historian would expect on the issue that the source leaves out; naming it shows you can judge the source against the wider picture, which limits its usefulness.
