Does Modern History scale well in the HSC? On the official numbers, Modern History scales moderately: it had a mean scaled mark of 25.0 out of 50 in the 2025 HSC, which puts it in the middle of the HSIE field and slightly ahead of Ancient History at 22.4. Neither is a high-scaling course in the way Mathematics Extension 1 or English Advanced is, and the gap between the two histories is small enough that it should almost never decide which one a student takes.
That is the short answer. The longer answer is more useful, because the way history courses scale is genuinely different from most subjects, especially once History Extension enters the picture. NextStepAcademy tutors have this conversation with Year 10 and Year 11 families every August, so here is the full version.
What did Modern History and Ancient History actually scale to?
From Table A3 of UAC’s Report on the Scaling of the 2025 NSW Higher School Certificate:
| Course | Students | Mean HSC mark | Mean scaled mark (out of 50) |
|---|---|---|---|
| Ancient History | 7,495 | 36.4 | 22.4 |
| Modern History | 10,953 | 37.1 | 25.0 |
| History Extension | 1,777 | 40.5 | 32.7 |
| Society & Culture | 4,957 | 38.9 | 23.1 |
| Geography | 4,419 | 38.0 | 25.2 |
| Legal Studies | 10,080 | 37.8 | 25.3 |
The 2.6 mark difference between Modern and Ancient History is real but modest. Put next to the roughly 20 mark spread across the whole HSC course list, it is not the sort of gap that rescues a disengaged student or sinks a committed one.
Where does history sit among the HSIE subjects?
Modern History sits alongside Geography and Legal Studies in a tight band around 25. Ancient History and Society & Culture sit a couple of marks below. History Extension sits well clear of all of them, and the reason for that is not what most students assume.
Why does History Extension scale so much higher?
Because it is not scaled on its own candidature the way a two-unit course is. UAC determines the scaled mean and standard deviation of an extension course from how those extension students performed in the corresponding two-unit course. History Extension is explicitly a special case in the report, because it can be taken by both Modern History and Ancient History students.
In plain terms: History Extension scales at 32.7 because the students who choose it are the strongest performers within the two history courses, not because the extension syllabus is intrinsically worth more. That mechanism is the same one behind Science Extension and the mathematics course ladder.
Does that mean adding History Extension will lift my ATAR?
Only if you perform in it. Taking an extension course does not import the course’s scaled mean into your results. Your scaled mark still depends on where you land within that candidature, and History Extension candidatures are small and strong. A student who scrapes through History Extension will not get 32.7.
What it does do is give a genuinely capable history student an extra unit that tends to scale better than their weakest two-unit subject, which is a legitimate reason to consider it.
Why does Ancient History scale slightly lower than Modern?
Scaling reflects the average academic achievement of everyone in the course, measured across all of their other subjects. Modern History is the larger course, with 10,953 students against Ancient History’s 7,495, and it is taken more often alongside English Advanced and other high-scaling subjects. Ancient History draws a slightly broader candidature.
Nothing in that describes the difficulty of the syllabus, the quality of the marking, or how hard you have to work. It describes who else is in the room. Our guide to how HSC scaling impacts your ATAR explains the mechanism in more detail, and the guide to reading the scaling report shows you how to check figures like these yourself.
Is Modern History harder than Ancient History?
They are different, not ranked. Modern History demands historiography and source analysis across contested modern material, where the evidence is abundant and the interpretations conflict. Ancient History asks you to work with fragmentary evidence, archaeology and ancient sources in translation, which suits students who like reconstructing an argument from limited material.
You can read both syllabuses on the NSW Curriculum website. In our experience, the students who do best in either course are the ones who genuinely enjoy the writing, because both are essay-heavy and the workload lands mostly in extended response practice.
Can you take both Modern and Ancient History?
Yes, and plenty of students do. It is a common pairing for students aiming at History Extension, since the extension course draws from both. The trade-off is that two essay-heavy HSIE courses plus English is a very heavy writing load, and students who choose that pattern need a study plan that spreads extended responses across the year rather than stacking them.
What does a strong history student actually scale to?
This is where course means mislead people. Table A3 also reports percentiles, and for Ancient History the 90th percentile of scaled marks in 2025 was 44.4, against a course mean of 22.4. A student in the top tenth of Ancient History was scaling into the mid 40s out of 50.
So the practical question is not “does this course scale well” but “can I finish in the top of this course”. Moving from the middle of the candidature to the top is worth far more than swapping to a course that scales two marks higher. That is exactly the shift a good tutor works on.
An illustrative example
Take two Year 11 students choosing between the two histories. Student A picks Modern History for the scaled mean, finds the twentieth century content dry, and finishes around the middle of the course. Student B picks Ancient History because she has wanted to study Pompeii since Year 7, writes willingly, and finishes in the top 10 per cent. On the 2025 figures, Student B’s scaled mark is comfortably higher despite choosing the “lower scaling” subject. This example is illustrative rather than a specific student, but it is the most common version of this story we see.
How should you decide?
- Choose on interest and writing stamina first. Both courses live or die on extended responses.
- Treat the 2.6 mark gap as a tiebreaker, not a reason. It matters only if you genuinely have no preference.
- Consider History Extension only if you are already strong. It rewards the top of the history cohort and punishes passengers.
- Check prerequisites. Very few university courses require either history, so this is usually a free choice.
Our broader HSC subject selection guide, and the companion pieces on the highest scaling HSC subjects and whether Society and Culture scales well, cover how these choices fit into a whole pattern of study.
Frequently asked questions
Does Modern History scale well?
It scales moderately. Modern History had a mean scaled mark of 25.0 out of 50 in the 2025 HSC, which is mid-range and similar to Geography and Legal Studies.
Does Modern or Ancient History scale better?
Modern History scaled slightly higher in 2025, at 25.0 against 22.4 for Ancient History. The gap is small and reflects who takes each course, not how hard they are.
Does History Extension scale well?
Yes. History Extension had a mean scaled mark of 32.7 in 2025, well above both two-unit histories, because it is scaled on how its students performed in Modern or Ancient History rather than on its own candidature.
Will these numbers be the same for the 2026 HSC?
Not exactly. Scaling is calculated after each cohort’s exams, so nobody can publish 2026 figures until after the 2026 HSC. Course relativities are usually stable year to year, but they are not a forecast.
Should I drop history because of scaling?
Rarely. Your position within a course affects your scaled mark far more than a two or three mark difference between course means. Finishing strongly in a subject you enjoy generally beats finishing mid-pack in one you chose for its scaled mean.
Getting help with HSC history
Both history courses reward one thing above all: writing a clear, well-evidenced extended response under time pressure. That is a coachable skill, and it is the fastest route to moving up within the candidature. Our HSC tutoring in Sydney team works with Modern History, Ancient History and History Extension students, in home and online across NSW.
