Source analysis and evaluation: WACE Modern History
“The skills of source analysis and evaluation, including identifying origin, purpose, perspective, reliability and usefulness for a historical inquiry”
Source analysis means moving beyond what a source says to analyse who made it, why, from what perspective, and how reliable and useful it is for a historian. The routine is: identify the origin and purpose, determine the perspective and what it reveals, then evaluate reliability and usefulness with reference to the source's context. The highest marks reward evaluation, not just description.
What this dot point is asking
Source analysis is one half of the external WACE Modern History examination and a skill assessed across both units. SCSA wants you to read previously unseen primary and secondary sources and answer questions about their meaning, perspective, reliability and usefulness. This guide teaches the routine that turns comprehension into genuine analysis and evaluation, the difference between average and top marks in the source section.
The foundation is comprehension, but it is only the foundation. You must first understand what a source actually says or shows. Read carefully, note the key claims, tone and details, and check any provided attribution that tells you the author, date and origin. For visual sources such as cartoons and photographs, identify the subject, symbols and message. Misreading the source dooms everything that follows, so accurate comprehension comes first, but the examination rewards going well beyond it.
Next, identify the origin and purpose. Ask who created the source, when, where and in what form: a speech, diary, official document, newspaper, cartoon or later history. Then ask why it was created and for whom. A wartime propaganda poster has a very different purpose from a private diary entry or a government memorandum. Origin and purpose shape everything about a source, and stating them precisely, using the attribution provided, is essential to higher-level analysis.
The core of source analysis is the trio of origin, purpose and perspective. Origin is who, when and what kind of source. Purpose is why it was made and for whom. Perspective is the point of view it expresses and the assumptions behind it. Establishing these three lets you evaluate reliability and usefulness with real authority rather than vague assertion.
Perspective is where analysis deepens. Every source expresses a point of view, shaped by the author's position, interests, beliefs and context. Identify whose perspective the source represents and what it reveals about how that person or group saw events. A source's perspective is not a flaw to be dismissed; it is evidence in itself. A biased source is still useful, because it reveals the attitudes and motives of its author. Analysing perspective is a major discriminator between mid-range and top responses.
Evaluation of reliability asks how trustworthy the source is as evidence for a particular claim. Consider the author's position and access to events, their purpose and possible bias, the type of source, and how it compares with other evidence. A source written long after events, or designed to persuade, must be treated with care. But reliability is always relative to a specific question: a propaganda poster is unreliable as a record of events yet highly reliable as evidence of what a regime wanted people to believe.
Evaluation of usefulness asks how valuable the source is for answering a particular historical question. Usefulness depends on relevance to the question, on what the source can and cannot tell you, and on its reliability for that purpose. Crucially, even unreliable or biased sources can be very useful, precisely because they reveal perspective, motive and propaganda. Always tie your judgement of usefulness to a specific inquiry and explain both the source's value and its limitations.
The skilful answer integrates all of this with reference to historical context. Bring your own knowledge of the period to bear: knowing what was happening when the source was made lets you explain its purpose and perspective and judge its reliability and usefulness convincingly. Practising this routine on past SCSA examination papers and marking keys is the single most effective preparation.
Do not simply describe or paraphrase the source and stop there, and do not dismiss a source as "biased and therefore useless". The strongest responses analyse origin, purpose and perspective and then evaluate reliability and usefulness for a specific question, recognising that even biased sources are useful evidence of attitudes and motives.
Historians treat sources as evidence to be interrogated, not as transparent windows onto the past. This guide trains the habits of interrogation that the external paper rewards. The companion skills pages on historiography and on constructing arguments extend these habits into the analysis of historical interpretations and the writing of extended essays.
A common source question gives you one source and asks you to evaluate its reliability or usefulness. Work through it in steps so you analyse rather than describe.
Step 1: Comprehend the source accurately
Read or view the source closely and state its main message in one sentence. For a cartoon or photograph, identify the subject, symbols and message. Misreading here undermines everything that follows.
Step 2: Establish origin and purpose
Use the attribution to state who made the source, when, where and in what form, then why and for whom. For example, a private diary records personal experience, while an official memorandum is intended to guide policy.
Step 3: Identify perspective
Explain whose point of view the source represents and the interests, beliefs or position that shaped it. Treat perspective as evidence in itself, not as a defect.
Step 4: Judge reliability against a specific claim
Assess how trustworthy the source is for the particular thing it is being used to show, weighing the author's access, purpose and possible bias against other evidence. Reliability is always relative to the claim.
Step 5: Judge usefulness against the inquiry
Conclude how valuable the source is for the historian's specific question, explaining both what it can reveal and its limitations, and noting that even a biased source is useful evidence of attitudes and motives.
Exam-style questions
Questions in the style of SCSA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
WACE 2021-style6 marksWith reference to its origin and purpose, assess the reliability of Source 1 (a wartime government propaganda poster) as evidence of conditions on the home front.Show worked answer →
A 6 mark reliability question wants origin and purpose tied to a judgement, not a paraphrase.
Origin and purpose. State that the source is an official government poster produced during the war to mobilise public effort. Its purpose is persuasion, not record, so it presents an idealised, selective picture.
Reliability judgement. Argue that it is unreliable as a literal record of home-front conditions, because it was designed to encourage rather than inform and omits hardship, dissent and shortages. However, make the key analytical move: it is highly reliable as evidence of what the government wanted people to believe and feel, which is itself valuable.
Markers reward the origin-purpose link, a judgement that is relative to the claim, and the recognition that an unreliable record can still be reliable evidence of attitudes.
WACE 2022-style8 marksEvaluate the usefulness of Sources 2 and 3 for a historian investigating this topic, referring to their content, origin and perspective.Show worked answer →
An 8 mark usefulness question wants a structured evaluation of each source against a specific inquiry.
Set up the inquiry. Restate what a historian would be investigating, because usefulness is always relative to a question.
Source by source. For each, identify origin (who, when, what kind), perspective (whose point of view and why), and what it can and cannot reveal. Note strengths (eg first-hand access, contemporary detail) and limitations (eg narrow viewpoint, propaganda purpose, hindsight).
Comparative judgement. Conclude which is more useful and why, and explain that even a biased or partial source is useful precisely because it reveals perspective and motive. Tie every point back to the inquiry.
Markers reward evaluation against the question, attention to origin and perspective, and the recognition that limitations do not equal uselessness.
