UAC does not publish a per-subject raw-to-scaled conversion for this course in a form we can quote exactly, so there is no figure on this page — the direction above is sourced from the UAC scaling report linked below, and should be read as directional rather than numeric.

You can't change the scaling. You can change the raw mark.

Scaling is decided by your cohort, after the exam, and nothing you do moves it. The raw mark is the only part of this you control — and the History Extension hub is 20 full-length model exams with mark-by-mark answer guides, revision notes, practice questions and flashcards, built for exactly that.

What History Extension actually asks of you

The HSC examination is a 50-mark written paper with 10 minutes reading time and 2 hours working time. Section I (25 marks) is one extended response on the key questions that may refer to one or two unseen passages. Section II (25 marks) is one extended response asking you to analyse an historiographical issue with specific reference to your case study. Each is expected to be about eight exam writing pages (approximately 1000 words) and is marked holistically in five mark ranges. The History Project is assessed by the school and is not part of the exam.

The History Extension exam is Wednesday 21 October 2026, 1:50 pm (2 hours 10 minutes (10 minutes reading plus 2 hours working)). Source: HSC timetable.

The 6 areas of study you are examined on

From the History Extension Stage 6 Syllabus (2017) — HSC Year 12 course and examination structure (2026 HSC).

  • Key question: Who are historians?
    The producers of history from ancient times to the present day; their identity (biographical details, personal values and beliefs, philosophy of history, approaches to the construction of history, bias); and their context (gender, class, ethnicity, time, place, social and economic structures and change, political constraints, official and unofficial status, academic background).
    In the exam: Examined through Section I and through Section II's focus on the historians in your case study (2021 asked about the influence of context; 2024 asked how far historians' individual contexts shape the recording of history).
    Where marks go missing: Treating context as biography: a strong answer shows how a specific context produced a specific interpretation.
  • Key question: What are the purposes of history?
    The aims and purposes of specific historical works and historians; changing interpretations and perspectives of the aims, purposes and role of history; and the use and misuse of history.
    In the exam: Examined through Section I: 2025 asked students to evaluate one historian's view of the aims and purposes of history, using the passage and at least two other sources.
    Where marks go missing: Listing famous statements about what history is for without judging the interpretation the question names.
  • Key question: How has history been constructed, recorded and presented over time?
    Changing methods of historians and how historians work; forms of historical communication (written, oral, visual, audiovisual, multimedia, digital); and types of history, from political, social, economic, environmental and military history to popular, national and local history, surveys, macrohistories, microhistories, biographies, psychohistories and historical fiction.
    In the exam: Examined in both sections: 2021 Section I asked how certain historians can be about the past; 2023 Section II asked how the form of communication influenced interpretations; 2025 Section II asked about historians' methods.
    Where marks go missing: Describing what an historian wrote instead of how and why their method produced that account.
  • Key question: Why have approaches to history changed over time?
    The availability of historical evidence; the contexts of historians; changing perspectives about approaches to the construction of history; changing philosophies of history; changing technology; and changing audiences.
    In the exam: Examined through Section I: 2022 asked how far changing technology influenced approaches to history, 2023 asked about the role of historiographical debate (counterfactual history) and 2024 about the role of historians in changing interpretations.
    Where marks go missing: A chronological survey of schools of history. Markers want an argument about causes of change, organised by idea, not by century.
  • Constructing History – Case studies (choose ONE)
    One case study is studied with reference to THREE areas of debate set by the syllabus and the key questions: historical and popular interpretations (including recent historiography), changing approaches, and how context, methodology, purpose, sources and form of communication shape interpretations. The 2017 list has 20 case studies (23 options) in five key areas: Ancient (Cleopatra VII; Athenian Democracy; Rome's Impact on the Provinces; The Origins of Early Christianity; The Collapse of the Western Roman Empire), Medieval and Early Modern (The Crusades; Witch Hunts and Witch Trials; Elizabeth I and the Elizabethan Age; Spain and the Aztec Empire), Modern (Napoleon; Western Imperialism in the 19th Century; Winston Churchill OR Margaret Thatcher; Appeasement; John Fitzgerald Kennedy), Asia (Genghis Khan; The Opium Wars; The Partition of India) and Australia (The Frontier in Australia; Women Convicts in New South Wales; Robert Menzies OR Gough Whitlam; Representations of Anzac).
    In the exam: Section II (25 marks) is one question for every case study. You identify your case study and refer to at least ONE area of debate; recent questions focus on context, the role of the academic, the form of communication, historians' contexts and historians' methods.
    Where marks go missing: Narrating the debate historian by historian. Better responses are driven by the question, select the most relevant historians, and sustain a judgement.
  • History Project
    An individual investigation into an area of changing historical interpretation: a proposal with a focus question, a process log, annotated sources (no more than 600 words), an essay of no more than 2500 words with consistent referencing, and a bibliography. The topic may grow out of the case study but must cover substantially different ground and must not overlap significantly with the examinable content of any Stage 6 course.
    In the exam: School-based assessment only; it is not examined in the HSC paper.
    Where marks go missing: Choosing a narrative historical topic rather than a genuinely historiographical question about how a topic has been interpreted.

How scaling works in New South Wales

In New South Wales, NESA reports an HSC mark for each course, but the ATAR is not built from those marks. UAC takes the raw examination and assessment marks and scales each course separately, so that a mark means the same thing no matter which course it came from. A course whose students perform strongly across everything else they study is scaled up; a course whose students perform less strongly elsewhere is scaled down. UAC then adds your best 10 units of scaled marks: the best two units of English, which are compulsory, plus the best eight remaining units. That aggregate is ranked statewide and reported as an ATAR. Scaled marks are usually lower than HSC marks, and the statewide average scaled mark is close to 25 out of 50.

What scaling is not

Scaling is not a difficulty rating and it is not a bonus. It compares how the students in one subject performed across every other subject they took, so a subject scales down because of its cohort, not because of the paper. The consequence is practical: you cannot scale your way out of a weak result. The only lever you control is the raw mark, and the fastest way to move that is full-length timed practice against the real exam format.

Questions

Does HSC History Extension scale up or down?

History Extension's scaled marks sit below its HSC marks. In UAC's Report on the Scaling of the 2025 NSW Higher School Certificate, the 1,777-student candidature averaged an HSC mark of 40.5 out of 50 but a scaled mark of 32.7 — the median scaled mark was 32.9 against a median HSC mark of 41.0. We do not publish a scaled figure for this course, because UAC does not release a per-subject conversion we can quote exactly. The UAC scaling report is the authority.

How does subject scaling work in New South Wales?

Should I choose History Extension because of how it scales?

Scaling adjusts a whole cohort, not one student, so choosing a subject you will struggle in because it scales up is usually a worse trade than doing well in one that scales down. Check the prerequisites for the course you want first, then your interest and workload, and treat scaling as a tie-breaker. Scaling is also recalculated every year, so the figures in any report describe a past cohort rather than the year you are sitting.
