What this dot point is asking
This skills strand underpins every assessment in Modern History. You must show that you can interrogate sources rather than simply describe them, and weave evidence into argument. Strong responses evaluate sources against each other and against your own contextual knowledge.
Primary and secondary sources
A primary source is evidence created at the time being studied or by a participant, such as a speech, photograph, diary, treaty, poster or newsreel. A secondary source is a later account or interpretation, such as a historian's book or article. Both are essential. Primary sources give direct evidence but are partial and shaped by their context; secondary sources offer analysis and the benefit of hindsight but reflect the historian's own perspective and the time of writing.
The analytical toolkit: origin, purpose, content
Effective evaluation starts with three linked questions. Origin asks who created the source, when and in what form. Purpose asks why it was created and for what audience, since a propaganda poster, a private diary and an official report serve very different ends. Content asks what the source actually says or shows, including its tone, language and what it leaves out. Together these reveal not just the information in a source but the conditions that shaped it.
Reliability, perspective and usefulness
Reliability asks how trustworthy the source is as evidence, considering bias, distance from events, and whether it can be corroborated. Perspective recognises that every source reflects a viewpoint shaped by the creator's position, interests and context; a source can be biased yet still highly useful as evidence of that viewpoint. Usefulness is always judged in relation to a particular inquiry: a wartime propaganda film may be unreliable about events but extremely useful as evidence of government aims and public mood. Distinguishing reliability from usefulness is one of the most rewarded skills in the subject.
Using sources in argument and corroboration
Analysis becomes history when sources are used as evidence in an argument. Strong responses cross-reference sources, noting where they agree, disagree or fill each other's gaps, and they bring in contextual knowledge to test and explain what the sources show. In the external examination this means quoting or referring precisely to the given sources, evaluating them, and connecting them to the question rather than retelling the source's content. In the folio it means selecting and integrating a range of sources to support a sustained, referenced argument.
Corroboration is central: a claim supported by several independent sources is stronger than one resting on a single document. Recognising silences, what sources do not say, and acknowledging the limits of the available evidence are marks of sophisticated analysis.
Exam-style practice questions
Practice questions written in the style of SACE Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2018 SACE Stage 22 marksHow useful is an obituary, such as Source 6, for historians researching a person? (Sources analysis, Question 19c. Refer to the separate sheet of sources.)Show worked answer →
A 2-mark usefulness question. SACE wants a balanced judgement of usefulness linked to the nature of the source type, not a list of contents. Make one point about strength and one about limitation.
- Strength (1 mark)
- An obituary is useful because it provides a concise summary of the key events, achievements and significance of a person's life, often written by someone with knowledge of the subject and published soon after death, so it captures contemporary assessment.
- Limitation (1 mark)
- It is limited because obituaries are conventionally celebratory and selective. They tend to omit faults or controversy, may rely on incomplete information at the time of death, and reflect the perspective of the writer or publication, so they should be corroborated against other sources.
- What earns the marks
- One clear strength and one clear limitation, each tied to the nature of an obituary as a source type. A judgement phrase ("useful for an overview but partial") secures the top of the band.
2018 SACE Stage 24 marksExamine Sources 4 and 5. With reference to the nature of the sources, assess the strengths and limitations of each source for historians researching Mawson. (Sources analysis, Question 19e. Refer to the separate sheet of sources.)Show worked answer →
A 4-mark evaluation question. Marks come from assessing each source's strengths and limitations with explicit reference to its nature (origin, type, purpose, perspective). Treat each source in turn.
Structure for the 4 marks (about one mark per judgement).
Source 4 strength. Identify the nature of the source (its type, author and purpose) and explain what makes it valuable, such as first-hand proximity, contemporary creation, or relevant expertise.
Source 4 limitation. Explain a weakness arising from that same nature: bias, narrow perspective, a purpose that shapes content, or limited scope.
Source 5 strength. Repeat for the second source, again grounding the judgement in its nature.
Source 5 limitation. Give a corresponding weakness.
What earns the marks. The phrase "with reference to the nature of the sources" is the key instruction. Generic comments ("it is biased") score poorly unless tied to why the specific type or origin produces that strength or limitation. A brief comparative note on which is more reliable for researching Mawson lifts the response.
2018 SACE Stage 27 marks'Mawson was motivated by a quest for scientific knowledge.' Evaluate this statement about Mawson with reference to all the sources. (Sources analysis, Question 19f. Refer to the separate sheet of sources.)Show worked answer →
A 7-mark synthesis question, the highest-value part of the sources analysis. It requires a sustained, evaluative response that uses all the sources as evidence for and against the statement, not a source-by-source description.
- Build an argument
- Take a position on whether scientific motivation was primary, then test it. Group sources that support a scientific quest (such as the expedition aims and scholarly accounts) against those suggesting other motives (national prestige, personal ambition, exploratory or commercial drives).
- Evaluate, do not just cite
- For each source used, weigh its reliability and perspective as you deploy it, because a source's origin affects how much weight its claim about motivation should carry. Cross-reference sources that corroborate or contradict one another.
- Mark-by-mark logic
- A top-band 7-mark answer states a clear contention, uses evidence from across all the sources, evaluates the reliability and perspective of those sources as part of the argument, weighs competing motivations, and reaches a justified conclusion. Mid-range answers summarise each source in turn without integrating them. The command word "evaluate" demands a weighed verdict, not a fence-sit.
2015 SACE Stage 22 marksSource 3 is a newspaper article reporting on events in Dublin. Explain two limitations of newspaper articles for historians researching an event. (Sources analysis, Question 45c. Refer to the separate sheet of sources.)Show worked answer →
A 2-mark question testing understanding of a source type's limitations. One mark for each clearly explained limitation of newspaper articles as historical evidence.
- Limitation 1 (1 mark)
- Newspapers may be biased or partisan. They are written for an audience and often reflect the political stance, ownership or nationality of the paper, so reporting on a contested event can be slanted or selective.
- Limitation 2 (1 mark)
- Newspapers report in the immediate aftermath with incomplete information. Early accounts can contain errors, rumour or propaganda, lack the benefit of hindsight, and may be shaped by wartime censorship or sensationalism.
- What earns the marks
- Two distinct, explained limitations tied to the nature of newspapers, not just "it is unreliable". Naming the mechanism (bias, haste, censorship, audience) is what secures each mark.
2015 SACE Stage 24 marksTo what extent do the statements in Source 5 support those in Source 6? (Sources analysis, Question 45d. Refer to the separate sheet of sources.)Show worked answer →
A 4-mark comparison question. Marks come from identifying specific points of agreement and disagreement between the two sources and reaching a judgement on the extent of support, using evidence quoted or paraphrased from each.
Method.
Points of support (about 2 marks). Identify specific claims in Source 5 that align with claims in Source 6, citing brief evidence from both to show the correspondence.
Points of difference (about 1 mark). Identify where the sources diverge, emphasise different aspects, or where one goes further than the other.
Judgement on extent (about 1 mark). Conclude clearly, for example "Source 5 supports Source 6 to a large but not complete extent", directly answering "to what extent".
What earns the marks. Specific cross-referenced evidence from both sources, not a separate summary of each. The explicit extent judgement is required by the command and is frequently where students lose the final mark.
