HSC English Extension 1 Scaling: Raw to Scaled (2026)
English Extension 1 scales up well. It is an elective taken on top of Advanced English by a self-selecting cohort, and UAC scales it above the state average.
Why there is no number on this page
UAC does not publish a per-subject raw-to-scaled conversion for this course in a form we can quote exactly, so we do not print one here. The UAC scaling report is the authority — read it below for the published figures, and take the direction described above as directional rather than numeric.
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 up 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.

Should I choose English Extension 1 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.
