How is the ATAR Calculated?

Posted on May 25, 2017 by DJ Kim

How is the ATAR calculated?

The ATAR (Australian Tertiary Admission Rank) is a rank calculated by UAC using an aggregate of scaled marks in 10 units of ATAR courses. These ATAR courses must include at least:

  • their best two units of English
  • their best eight units from their remaining units, which can include up to two units of Category B courses

What is the process for calculating the ATAR?

Read the following 7 steps on how the ATAR is calculated.

Step 1: School assessments are used to assign overall assessment mark and rank in each subject.

Step 2: All students sit a common HSC Exam for each subject

Step 3: The NESA (previously known as BOSTES) determines your HSC mark using your HSC exam mark and moderated assessment mark.

Step 4: UAC scales each subject out of 50 for comparison across subjects.

Step 5: UAC determines each student’s aggregate of scaled marks out of 500.

Step 6: The aggregate mark out of 500 is used to determine your percentile.

Step 7: ATAR is your percentile score, rounded to the nearest 0.05.
