QCE Modern History IA1 historical investigation: the 2026 guide

What this guide is for

QCE Modern History IA1 is a major Unit 3 assessment (25 percent). Strong performance requires source-analysis fluency, structured argument, and disciplined exam technique. This guide covers all three.

Format

• Duration. 2 hours supervised, plus 10 minutes perusal.
• Word count. 600-800 words.
• Stimulus. 3-5 historical sources (primary and secondary) on Unit 3 topic.
• Worth. 25 percent of subject result.

Five-part essay structure

Introduction (around 100 words).

Three sentences:

1. Opening claim about the topic.
2. Contention (direct answer to the prompt).
3. Signpost: three lines of argument the body will develop.

Body paragraph 1 (around 150-200 words).

First line of argument. Engage at least one source. Apply OPCVR. Argue effect.

Body paragraph 2 (around 150-200 words).

Second line. Complicate or qualify the first. Engage with another source.

Body paragraph 3 (around 150-200 words).

Third line. Whole-text or structural-level argument. Engage with a third source.

Conclusion (around 60 words).

Reassert the thesis. Note historiographical contestability.

OPCVR source analysis

For each source you cite:

Origin. Who created? When? Where?

Purpose. Why was it created? For what audience?

Context. What was the broader historical situation?

Value. What can this source tell us about the topic?

Reliability. How trustworthy as evidence? What limits reliability?

Apply systematically. Strong responses do not just cite sources; they analyse them.

Source integration in body paragraphs

A reliable internal shape:

1. Topic sentence linking to thesis.
2. Reference to source by tag, with embedded short quotation.
3. OPCVR analysis (especially value and reliability).
4. Argue what the source shows about your line of argument.
5. Closing sentence linking forward.

A worked body paragraph

For an IA1 on Australian conscription debates 1916-17:

The class divide that shaped opposition to conscription in 1916-17 is most clearly visible in the trade union and IWW responses. Source B, the cartoon from the Industrial Workers of the World (IWW) campaign (October 1916), depicts a wealthy businessman urging working-class Australians to fight while remaining safely at home; the cartoon's purpose is propagandistic but its value lies in revealing the class-based critique that drove much of the No vote. Source D, a historian's interpretation by Don Aitkin (1969), confirms that 'the No vote in 1916 was strongest in working-class districts of Sydney and Melbourne and weakest in the rural conservative seats.' Together the sources expose the class basis of opposition: a contemporary cartoon shows the rhetoric of resistance; a historian's secondary analysis confirms the demographic pattern.

A response of this kind, integrating two sources with explicit OPCVR awareness and argumentative purpose, secures top band.

Time management

Perusal (10 minutes). Read all sources carefully. Underline key phrases. Annotate the prompt. Sketch a plan.

Drafting (90 minutes). Write the essay. Do not exceed 800 words; markers expect tight responses.

Review (20 minutes). Proofread. Add source citations. Tighten arguments. Check the conclusion ties back to the introduction.

Common errors

Plot summary. Retelling source content rather than analysing.

Generic OPCVR. Mechanical application without source-specific evidence.

Sources treated as transparent. Treating primary sources as direct truth.

Long block quotations. Embed short phrases.

Missing source citations. Each body paragraph should reference at least one source by tag.

Wrong directive verb. "Discuss" expects balance; "evaluate" expects judgement; "analyse" expects systematic breakdown.

In one sentence

QCE Modern History IA1 is a 2-hour 600-800 word essay on a Unit 3 question using a stimulus pack of 3-5 unseen historical sources; top-band responses use the five-part structure (introduction, three body paragraphs each integrating at least one source with OPCVR analysis, conclusion) and the four-step source pattern (cite by tag, embed quotation, apply OPCVR, argue effect) to construct an argument that engages with multiple perspectives.
