What this dot point is asking

The essay section is the other half of the external WACE Modern History examination, and essay writing is assessed throughout the course. SCSA wants you to write extended responses that argue a clear thesis, sustain it across well-structured paragraphs, support it with specific evidence, and engage with historical interpretation. This guide teaches the craft of the historical essay, which rewards argument over narrative and analysis over description.

Everything begins with the question. Read it carefully and identify exactly what it asks. Modern History questions are usually analytical, asking you to assess causation ("why"), significance, change, or the extent to which a statement is true ("to what extent", "how far"). The command words matter: a question asking you to "evaluate" or judge "to what extent" demands a weighed argument, not a description. Underline the key terms and the timeframe, and make sure you address the actual question rather than a general topic.

The thesis is the heart of the essay. A thesis is your direct, arguable answer to the question, stated clearly in the introduction. It should take a position, for example that a factor was the most important cause, or that change was significant but limited. A good thesis previews the line of argument the essay will develop. Without a thesis, an essay becomes narrative; with one, every paragraph has a job to do in supporting the case.

Structure carries the argument. Use a clear introduction that responds to the question and states the thesis, body paragraphs each developing one point in support of the argument, and a conclusion that draws the case together and returns to the question. Within each paragraph, state the point, support it with specific evidence, explain how the evidence supports the point, and link back to the question. This discipline keeps the essay analytical and prevents drift into narrative.

Evidence must be specific and accurate. General assertions persuade no one; precise evidence does. Use exact dates, named figures, specific events, statistics and terms. Compare a vague claim that "many people were persecuted" with a precise statement about the Nuremberg Laws of 1935 or the scale of the purges. Deploy evidence to prove your points, not to fill space, and make sure it is accurate, since errors undermine your authority.

Engaging with historiography lifts an essay further, as the companion skills page explains. Where relevant, frame the debate, take a position, and use named historians to support your argument and to represent the view you are arguing against. This shows you understand the question as a contested historical problem. Use historiography to structure thinking, not as decoration.

Finally, sustain relevance and judgement throughout. Keep returning to the question, especially in "to what extent" essays, where you must reach a balanced but clear judgement: acknowledge the other side, then explain why your position is stronger. The conclusion should answer the question decisively rather than merely summarising. Planning briefly before you write, mapping your thesis and paragraph points, makes all of this far easier under examination conditions.

Essay writing is the skill that integrates everything else in the course: knowledge of content, source-based evidence and historiographical awareness, all marshalled into a sustained argument. Practising under timed conditions on past SCSA questions, then checking against the marking keys, is the most effective way to improve.
