Understanding HSC Structure

The Higher School Certificate (HSC) is structured as follows:
  • Preliminary HSC (Year 11)
  • HSC Year (Year 12)
Key Points:
  • • Must complete Preliminary course before HSC
  • • Minimum of 12 units for Preliminary
  • • Minimum of 10 units for HSC year

Subject Requirements

Your HSC program must include:
  • At least 2 units of English (mandatory)
  • At least 6 units of Board Developed Courses
  • At least three courses of 2 units or greater
  • At least four subjects
  • Maximum of 6 units of Science courses

HSC Assessment Structure

HSC marks are determined by:

School Assessment

50% of your final mark comes from school-based assessments throughout Year 12

HSC Examination

50% comes from your HSC exam results

Understanding Your ATAR

The ATAR (Australian Tertiary Admission Rank) is:
  • A rank between 0.00 and 99.95
  • Based on your best 10 units (including 2 units of English)
  • Calculated using scaled marks, not raw HSC marks
Important Note: Your ATAR is a rank, not a mark. It indicates your position relative to other students.

Why use our Calculator?

Our calculator is one of the most accurate calculators around because we use data from the past 2 years released by each state to get the best estimate of your ATAR score.

Your actual ATAR will be scaled according to the performance of everyone in your state that year, so it may differ from our estimate. Our calculator, like all other ATAR calculators, can only give you an estimate of your ATAR based on historical data.

How is your ATAR calculated?

The Australian Tertiary Admission Rank is a number between 0.00 and 99.95 that indicates your position relative to all the students in your age group (ie all 16 to 20 year olds in NSW). So, an ATAR of 80.00 means that you are 20 per cent from the top of your age group (not just your Year 12 group).

To qualify for an ATAR, you must:

  • Complete five General subjects, or a mix of four General subjects plus one Applied subject or VET qualification (Certificate III or higher).
  • Achieve a minimum grade of C in an English subject (though this may not be used in your ATAR calculation depending on what state you’re in).

HSC ATAR Calculation

The ATAR is calculated by:
  1. Scaling your raw HSC scores according to the difficulty of your chosen subjects
  2. Adding the scaled marks to get an aggregate
  3. Ranking your aggregate against students in NSW in your year group

How are your results scaled?

Scaling adjusts raw study scores so that students across different subjects are assessed on a level playing field. This makes sure that students and their ATARs are ranked correctly according to their abilities.

High scaling subjects are those that are perceived as more difficult, and consequently, students may receive higher-scaled marks for achieving the same raw mark compared to subjects considered low-scaling. High-scaling subjects often include math extension, physics, chemistry, and certain languages such as Latin.

HSC Scaling

NESA has a very unique method in which they scale their subjects. First, they align the raw marks to bands that best describe the standards that the students achieve. This can compress a range of raw marks to a smaller number of HSC marks. For example, all Band E4 performances in English Extension 1 are allocated one of the six integer grades 45.0 to 50.0. Thus, after aligning and rounding, for each HSC mark, there can be a range of corresponding raw marks and hence a range of scaled marks. In general, there is no unique scaled mark for an HSC mark, however, trends can be found giving some students an edge.

How to Optimise your ATAR

If your subjects scale well, great for you! But if it doesn’t, it’s not the end of the world. A general misconception about scaling is that it “punishes” students for taking certain subjects. In reality, it is designed to ensure fairness, not to discourage or favour any particular subject.

Don’t pick subjects based on scaling, but based on what you’re realistically good at and interested in. After all, a raw 50 will still be a scaled 50 (or even more!) no matter which subject you take.

To perform well for the ATAR, it's more than just understanding scaling:

  • Balance Interest and Strengths: Choose subjects you enjoy and excel at. Passion often translates into better results.
  • Check Prerequisites: Many university courses require specific subjects. For example, engineering might need Mathematical Methods and Physics.
  • Diversify Your Selection: Opt for a mix of subjects to keep your options open. For instance, combine sciences with a humanities subject to develop a broader skill set.
  • Seek Advice: Consult teachers, career counsellors, and even university course guides to make informed decisions. Also, ask older students for insights—they've been through it all and can offer valuable tips.
