Engineering Studies Scaling HSC 2026: Does It Scale Up or Down?

HSC Engineering Studies scales down in New South Wales. In UAC’s Report on the Scaling of the 2025 NSW Higher School Certificate, Engineering Studies students averaged an HSC mark of 36.8 out of 50 per unit and a scaled mark of 26.2; the median scaled mark was 26.4 against a median HSC mark of 37.0.

Engineering Studies scales down in New South Wales.

In UAC’s Report on the Scaling of the 2025 NSW Higher School Certificate, Engineering Studies students averaged an HSC mark of 36.8 out of 50 per unit and a scaled mark of 26.2; the median scaled mark was 26.4 against a median HSC mark of 37.0. 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 Engineering Studies hub is 20 full-length model exams with mark-by-mark answer guides, revision notes, practice questions and flashcards, built for exactly that.

The hub shows a sample revision note extract, one full exam question with its worked answer and the complete list of every exam and note title — no account needed to look around. Unlocking Engineering Studies for life is $20 once, or $50 for any three subjects. See what's included →

What Engineering Studies actually asks of you

The HSC exam is one written paper worth 100 marks: 5 minutes reading time and 3 hours working time, with a formulae sheet provided. Section I has 20 marks of objective-response (multiple-choice) questions, about 30 minutes. Section II is worth 80 marks: about seven short-answer questions (Questions 21–27 in every paper from 2021 to 2025) split into parts, about 25 items in total, with at least two items worth 6 to 8 marks; allow about 2 hours 30 minutes. The four modules carry approximately equal weighting and questions may integrate the whole course. NESA-approved calculators may be used; drawing questions are answered with drawing equipment in pencil. Your HSC mark is the average of your exam mark and your moderated school assessment mark; the Year 12 school-based components are Knowledge and understanding of course content (60%) and Knowledge and skills in research, problem solving and communication related to engineering practice (40%).

The Engineering Studies exam is Tuesday 20 October 2026, 9:25 am (3 hours 5 minutes (5 minutes reading plus 3 hours working)). Source: HSC timetable.

The 5 areas of study you are examined on

From the Engineering Studies Stage 6 Syllabus (2011, amended) — HSC course (four compulsory modules).

  • Civil structures
    Bridges, buildings, dams, cranes and playgrounds: their history, materials over time, and social and environmental impact, including recycling when structures are replaced. Engineering mechanics: pin-jointed truss analysis by the method of joints, method of sections and graphical methods; shear force and bending moment diagrams for simply supported beams with point loads, neutral axis and bending stress σ = My/I; the effect of uniformly distributed loads (no calculation); stress and strain, the stress/strain diagram, Young’s modulus, yield and proof stress, toughness and factor of safety. Materials: X-ray and concrete testing, crack theory, glass, cement and bricks, composites (timber, reinforced, pre-tensioned and post-tensioned concrete, asphalt, laminates, geotextiles) and corrosion protection.
  • Personal and public transport
    Bicycles, cars, buses, trucks, trains and trams: history, design features and environmental impact of transport energy and materials. Mechanics: mechanical advantage, velocity ratio and efficiency; static friction, angle of friction and angle of repose; work, kinetic and potential energy and power. Materials: hardness and impact testing; annealing, normalising, hardening and tempering of steels and the resulting microstructures; forging, rolling, casting, extrusion, powder forming and welding; non-ferrous alloys and solid solution hardening; toughened and laminated glass; thermosoftening polymers, textiles, extrusion, injection and blow moulding. Electricity: generation and distribution, simple circuits, electric motors and speed control, control technology and electrical safety.
  • Aeronautical engineering
    The aeronautical engineering profession — its scope, projects, safety, training, careers, ethics and the engineer as manager — and the history of flight in Australia and its environmental effects. Flight mechanics: lift, weight, thrust and drag, lift to drag ratio, angle of attack and stall; Bernoulli’s principle and the venturi effect; bending stress in airframes; piston, turboprop, turbofan, ramjet, scramjet and rocket propulsion; Pascal’s principle, hydrostatic and dynamic pressure, the altimeter and pitot tube. Materials: non-destructive testing (dye penetrant, X-ray and gamma ray, magnetic particle, ultrasonic), aluminium alloys and age hardening, thermosetting polymers and lay-up and compression moulding, composites including Kevlar, carbon fibre and Fibre Metal Laminate, and corrosion in airframes.
  • Telecommunications engineering
    The telecommunications profession — scope, WHS, careers, ethics, privacy and security — and the history of the industry, including black-and-white and colour cathode ray television. Materials: voltage, current, insulation and signal-strength testing; copper beryllium, brass and electrolytic tough pitched copper; semiconductors such as transistors, zener diodes, LEDs and laser diodes; insulating polymers and fibre optics. Electronics: analogue and digital systems, modulation and demodulation, AM, FM and digital radio, digital television and display media, fixed and mobile telephony, transmission media and the electromagnetic spectrum, geostationary and low Earth orbit satellites and GPS, and AND, NAND, OR and NOR logic gates.
  • Engineering communication and reports
    Drawing to Australian Standard AS 1100: third-angle orthogonal views, line types and dimensioning, assembly drawings and sectional views; freehand, pictorial and isometric sketching; developments of transition pieces; graphical solutions to mechanics and aerodynamic problems; CAD as a communication and problem-solving tool. In each HSC course a student writes two Engineering Reports (one from an application module, one from a focus module), one of them collaboratively.

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 Engineering Studies scale up or down?

In UAC’s Report on the Scaling of the 2025 NSW Higher School Certificate, Engineering Studies students averaged an HSC mark of 36.8 out of 50 per unit and a scaled mark of 26.2; the median scaled mark was 26.4 against a median HSC mark of 37.0. 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.

Should I choose Engineering Studies 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.
