A "to what extent" question asks how much, so your answer is a degree (to a significant, moderate, or limited extent) and the reason for it. Put that judgement in your first sentence, test it in every paragraph against the evidence, including the evidence against you, and finish on the same judgement.
It's the first line of every top band in the marking guidelines. Here's how NESA's 2025 guidelines for Section IV, the 25-mark extended response, open the top 3 bands:
21-25: Provides a perceptive judgement relevant to the question
16-20: Provides a judgement relevant to the question
11-15: Provides some judgement relevant to the question
Below 11, judgement isn't in the criteria at all.
I teach Year 12 Ancient History, including The Greek World 500-440 BC, and I mark school assessment tasks on it. The essay that gets stuck in the middle bands is usually the one that knows plenty and never commits to how much. Here's how to commit, using a real HSC question on the Delian League.
Where "to what extent" questions turn up in the HSC
If you're sitting the 2026 HSC, Ancient History is on Friday 23 October, 9.25 am to 12.30 pm. You're on the Ancient History Stage 6 Syllabus (2017), and so is next year's Year 12. The new Ancient History 11-12 Syllabus (2024) has its first HSC exam in 2028.
The paper has 4 sections of 25 marks, and each one says to "Allow about 45 minutes for this section". "To what extent" questions mostly sit in 2 of them:
- Section IV, Historical Periods. One extended-response question on your topic, with 2 alternatives, and you answer one. NESA expects "around eight pages of an exam writing booklet (approximately 1000 words)". From 2019 to 2025, between 7 and 11 of the 20 alternatives each year began "To what extent".
- Section III, Personalities in their Times. In 4 of those 7 papers (2020, 2021, 2023 and 2024), every personality question had a "to what extent" part worth 10 or 15 marks. In 2024 it was "To what extent was [the personality] successful?" The other years used "assess" or "discuss" instead.
The core has used it too, for 8-mark source questions in 2020 and 2021. Those are closer to the source analysis guide.
What "to what extent" is asking
It isn't in NESA's glossary of key words. The glossary page lists it among the "self-explanatory terms" that exam questions "will continue to incorporate". The nearest key word is assess:
Assess: Make a judgement of value, quality, outcomes, results or size.
The questions come in 2 kinds, and each needs a different measuring stick:
- Factor questions ("contribute to", "the main cause of", "responsible for") name one cause. You judge how big a part it played by weighing it against the other causes. 2024: "To what extent did urban violence contribute to the fall of the Roman Republic?"
- Claim questions ("successful", "deserve the title", "the turning point", "achieve its aims") make a claim. You set criteria for it, then test it. 2025: "To what extent does Darius I deserve the title 'the Great'?" In 2025, better responses on Nero could "evaluate the relative success of Nero as a princeps through establishing some criteria by which the success can be measured".
Either way, the degree on its own isn't the judgement. NESA's 2025 feedback on Section IV:
This judgement should be something more than a simple adjective and should shape the whole response, incorporating historical information that supports the judgement, evaluative language tailored to the needs of the question, and an argument that is sustained across the length of the response.
"To a significant extent" is the adjective. "To a significant extent for the war on Persia, but only to a limited extent for liberation, because ..." is the start of a judgement. Markers asked for exactly this in 2022 and 2024: "expanding on evaluative statements so that they are more than adjectives".
Same topic, different question
NESA has set the Delian League in Section IV twice:
- 2020: "Why did the Delian League transform into the Athenian Empire?"
- 2022: "To what extent did the Delian League achieve its aims?"
The content overlaps, but the job doesn't. In 2020, markers saw detailed responses that "focused on 'how' the league transformed into Empire but did not refer to or draw out conclusions of 'why'". In 2022, they asked students to focus "on the specific question, the extent to which the Delian League achieved its aims, rather than the transformation into the Athenian Empire."
The same prepared essay missed both. In 2025 the topic came from a third angle: "To what extent were the activities of the Peloponnesian League a response to Athenian imperialism during this period?" Learn the period, not one essay. NESA's general feedback asks you to "engage with what the question is asking rather than presenting a pre-prepared response".
A method for the exam
- Underline the claim and its limits. In "achieve its aims", that's which aims, whose, and by when (your period ends in 440 BC).
- Pick your measuring stick. For a factor question, list the other causes you'll weigh. For a claim question, set 2 or 3 criteria.
- Decide the degree before you write. One sentence: the degree, the main reason, and the limit. That's your first sentence. A rough degree is enough to start; you can sharpen the wording as you write, as long as you don't switch sides.
- Plan 3 or 4 paragraphs, one per aim, criterion or factor. In 2019, better responses would "include an opening sentence for each paragraph with each of the themes and connect them to the overall judgement using the appropriate key word".
- Put the evidence against you inside your paragraphs, then say why your judgement still holds, or adjust it.
- Conclude with the same judgement, in its sharpest wording. Better 2019 responses included "a succinct summative conclusion reinforcing the judgement made."
Steps 1 to 4 take about 5 of your 45 minutes, and they're the 5 minutes that stop you writing the essay you prepared. Each body paragraph is a PEEL paragraph whose Point is a mini-judgement.
A worked example: the Delian League
The question
To what extent did the Delian League achieve its aims? (25 marks)
This is the real 2022 HSC question (Section IV, Question 28 (b), The Greek World 500-440 BC). The sample answers are mine, written for this guide. They aren't NESA material or student work.
A weaker introduction (sample)
The Delian League was formed in 478 BC after the Persian Wars, with Athens as its leader. Over the next 30 years Athens transformed the League into an empire. It forced Naxos and Thasos to stay in the League, moved the treasury from Delos to Athens and used the money to build the Parthenon. This essay will discuss how the Delian League became the Athenian Empire and to what extent it achieved its aims.
It's the transformation essay with the question's words stapled to the end. It never says what the aims were, so it can't judge them. "Used the money to build the Parthenon" also overstates what we know: NESA's own feedback says Pericles' building program was financed "at least in part" by League funds. And "will discuss" promises the wrong thing: NESA's 2023 feedback reminded students that "'discuss' does not require a judgement to be made".
A stronger introduction (sample)
The Delian League achieved its aim of revenge on Persia to a significant extent by about 450 BC, but its aim of liberating Greek states only to a limited extent, because the autonomy that liberation assumed did not survive Athenian leadership. Thucydides gives the League's "professed object" in 478/7 BC as revenge on the Persian king, and P. J. Rhodes adds the protection and liberation of Greek states from Persia, in an alliance "whose autonomy was taken for granted". Against Persia, campaigns from Eion to the Eurymedon largely succeeded, despite the disaster in Egypt. But the subjugation of Naxos, the crushing of Thasos and the move of the treasury to Athens show states freed from Persia losing their autonomy to Athens instead.
A stronger body paragraph (sample)
The League's war on Persia, the aim Thucydides names, succeeded to a significant extent. In about 476/5 BC its forces under Cimon captured Eion on the Strymon from the Persians, and at the Eurymedon River, in about 469-466 BC, Cimon "won both battles on the same day", destroying a Phoenician fleet that Thucydides puts at 200 ships. Egypt shows the limit of that success. Sent to support a revolt against Persia, the expedition "came to ruin after six years of war" in about 454 BC, and a relieving squadron of 50 ships was mostly destroyed. Yet the League recovered, winning by land and sea off Salamis in Cyprus in about 450 BC. Whether a formal peace with Persia followed, the Peace of Callias, is disputed, partly because Thucydides never mentions one. His wording matters as well: "professed object" translates a Greek word that can mean "pretext", and Rhodes asks why Thucydides chose it. It suggests Thucydides believed Athens wanted more than revenge, though it doesn't cancel the victories. Measured against the aim it declared, the League succeeded to a significant extent, and Egypt is the reason that falls short of complete.
The next paragraph would test the second aim, liberation, against the autonomy it assumed. It would use Naxos, which Thucydides calls "the first instance of the engagement being broken by the subjugation of an allied city", then Thasos, then the treasury's move to Athens, traditionally dated 454/3 BC. That's where Athenian imperialism belongs in this answer: as evidence about how far the aims were met. NESA's 2022 markers warned that "it is important to avoid solely focusing on Athenian Imperialism".
Why the stronger answer works
- It names the aims before judging them, and keeps them apart from what they assumed: autonomy was a condition of the alliance, not one of its aims. In 2022, better responses could "clearly identify the aims of the League and make a judgement about the extent to which the aims were met".
- The judgement is split, with a reason joining the halves. It's significant for the war on Persia and limited for liberation, because the League's success against Persia gave Athens the power to take away the autonomy liberation assumed. That's more than an adjective.
- The evidence against it sits inside the paragraph. Egypt doesn't get a paragraph of its own to be forgotten in; it limits the judgement to "falls short of complete".
- It uses the source's purpose, not just its name. "Professed object" tells you something about Thucydides. NESA's 2025 feedback asks for "an understanding of the purpose and intentions of ancient sources and modern historians, rather than appending their names to the phrase 'according to'".
- It uses modality where the evidence is uncertain: "about", "is disputed", "suggests". In 2022, markers asked for "using modality, that is, the degree of certainty to frame an argument when responding to a 'to what extent' question".
- The paragraph ends in the question's words, so the marker never has to guess how it connects.
Check your answer before you move on
- Does my first sentence give a degree and a reason, in the question's words?
- Have I said what I'm measuring: the aims, my criteria, or the other factors?
- Does each paragraph end by saying how far it supports my judgement?
- Have I dealt with the evidence against me, inside the paragraphs?
- Does my conclusion give the same judgement as my introduction?
A no tells you which step to redo.

Frequently asked questions
Should my judgement go in the introduction?
Yes. In 2019, better responses on the Augustan Age would "make a perceptive and holistic judgement based on the key words in the introduction". Your conclusion should then reinforce the same judgement, not reach a new one.
How is "to what extent" different from "discuss"?
NESA's glossary defines discuss as "Identify issues and provide points for and/or against", and its 2023 feedback reminded students that "'discuss' does not require a judgement to be made". "To what extent" always does. If your plan lists points for and against with no degree, it's a discuss plan.
Is there a right answer to a "to what extent" question?
No single one. NESA's 2021 feedback on a core "to what extent" question said "there is no single 'correct' way to answer this question", and excellent responses argued it both ways. What's marked is how well your evidence supports the judgement you make.
