What this dot point is asking

Ancient History rests on evidence, and the central skill of the course is analysing sources. Sources are usually divided into primary sources, which come from the period being studied, such as inscriptions, coins, pottery, papyri, monuments and contemporary writings, and secondary sources, which are later interpretations, including the work of modern historians and even ancient writers describing earlier times. A key complication for ancient history is that a writer such as the Roman historian Livy, writing under Augustus about events centuries earlier, is a primary source for his own age but a secondary source for the early Republic he describes.

A reliable method gives you something repeatable to do under exam pressure. A common routine is to identify origin, purpose, audience, reliability and usefulness. Origin asks who made the source, when and where. Purpose asks why it was made and what the maker wanted to achieve. Audience asks who it was meant for. Reliability asks how trustworthy the content is, given the maker's knowledge and motives. Usefulness asks what the source can and cannot tell us for a specific inquiry question. Crucially, a source can be unreliable yet still useful, because even propaganda is good evidence for what a regime wanted people to believe.

Different categories of evidence carry different problems. Written sources may be biased, incomplete or copied with errors across centuries of manuscript transmission, and many survive only in fragments or in quotations by later writers. Archaeological evidence, such as the ruins of Pompeii buried by Vesuvius in 79 CE, can show daily life directly but rarely speaks to motive or named events. Inscriptions and coins are contemporary and official but were designed to project power, like the portrait and slogans on imperial coinage. Material from the ancient world also reaches us through chance survival and through the choices of collectors, so the record is uneven and skewed toward the wealthy and powerful.

Strong source work also weighs sources against each other and judges contestability. Historians cross-check a royal inscription claiming victory against archaeology, against rival accounts and against later evidence, as they do with the Battle of Kadesh, which Egyptian monuments present as a triumph but which was probably a draw. Where sources conflict, the past becomes contestable, and an answer should acknowledge competing interpretations rather than pretend the evidence is settled.

For the TASC external examination, source analysis is a core demand, so practise the routine on real ancient evidence until it is automatic: name the origin and purpose, judge reliability against the maker's motives, assess usefulness for the question asked, and corroborate with other sources. This method turns a pile of fragments into an argument supported by evidence, which is exactly what the assessment criteria reward.

Exam-style practice questions

Practice questions written in the style of TASC exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

2022 TASC"Evidence, at times incomplete and imperfect, is used to understand and explain significant features of the ancient past." Assess the usefulness of sources in providing an understanding of the impact of one (1) ancient site, significant event, development or era on the nature and historical context of an ancient civilisation. Make reference to the primary and secondary sources associated with one ancient site, significant event, development or era that you have studied. In doing so, refer to the origin, purpose, context and reliability of those sources.

This is the Section A essay (Criteria 3, 4 and 5). The marker rewards a sustained argument, not a list, so frame a thesis: the surviving evidence for your chosen site or event is partial and shaped by its makers, yet careful analysis still yields a defensible understanding.

Method to show. For two or three key sources, work through origin (who, when, where), purpose (why it was made), context, and reliability, then judge usefulness for the specific inquiry. Stress that an unreliable source can still be useful, for example propaganda is strong evidence for what a regime wanted believed.

Worked spine using the Res Gestae of Augustus. Origin: a first-person record inscribed after 14 CE. Purpose: to fix how Romans remembered the reign. Reliability: low for balance, since it omits the proscriptions. Usefulness: high for Augustan self-image, low as a neutral account of how power was won. Set this against a hostile source such as Tacitus to show how corroboration builds understanding from imperfect evidence.

To reach the top criteria, name the gaps the evidence leaves and explain how historians work around them.

2021 TASC"The evidence that exists has a direct impact on how reliable, contested and/or valid our understanding of the ancient past is." Discuss this quotation, making reference to the primary and secondary sources associated with one (1) ancient site, significant event, development or era that you have studied. In doing so, refer to the origin, purpose and context of those sources.

A Section A response (Criteria 3, 4 and 5). Argue that the quantity and quality of surviving evidence directly sets the limits of what can be known, so understanding is reliable where sources corroborate and contested where they conflict or fall silent.

Structure each body paragraph around one source: state its origin, purpose and context, then judge what it can and cannot support. Show contestability by pairing sources that disagree, for example an official inscription against a later literary account, and explain why historians weight them differently.

Use the analytical vocabulary the criteria reward: reliable, contested, valid, corroboration, bias, gap. Conclude by linking evidence directly back to the strength of your understanding: where the record is thick and consistent the interpretation is secure, where it is thin or one-sided the conclusion must stay provisional.
