Selection into undergraduate courses is based on both eligibility and rank. Eligibility allows you to be considered for selection; rank determines whether you are competitive enough to be selected.


If you are completing the SACE/NTCET, to be eligible for selection into an undergraduate course/program you must: 

  • qualify for the SACE/NTCET
  • obtain an Australian Tertiary Admission Rank (ATAR)
  • meet any prerequisite subject requirements for the course/program.

If you are undertaking the International Baccalaureate (IB) in a school in Australia to be eligible for selection into an undergraduate course/program you must:

  • complete the IB Diploma
  • obtain a minimum IB score of 24 points (your IB score is then converted to an equivalent ATAR)
  • fulfil any prerequisite subject requirements for the course/program

If you are completing an Australian year 12 program interstate (except Queensland) you must receive an ATAR. If you are completing year 12 in Queensland you must receive an Overall Position (OP). You must also fulfil any prerequisite subject requirements for the course.


Your competitiveness in relation to other applicants is based on your ATAR which is a rank given to students on a range from 0 to 99.95. Your ATAR is calculated from your university aggregate. 

Find out how the university aggregate and ATAR is calculated.

IB to ATAR conversion table

The following table shows how the IB points (in the range 24-45) are converted to an equivalent ATAR.

IB points* Equiv. ATAR
45 99.95
44 99.85
43 99.70
42 99.40
41 98.80
40 98.25
39 97.50

*IB points total (in the range 24-45), derived from the results gained in both Higher Level and Standard Level subjects and possibly augmented by bonus points based on the standard achieved in the Extended Essay and Theory of Knowledge.

Australian year 12 results comparison table

The following table provides students who are completing an Australian year 12 program in 2018 with information about how their results compare across Australia. The table relates to 2017 results and is a guide only.

As the table shows, an ATAR of 81.00 in any state or territory (except Queensland) is the same as an ATAR of 81.00 from any other state or territory (except Queensland). So if you are completing your year 12 studies in 2018 or later in one of these states or territories and are planning to apply to institutions in other states or territories, your ATAR remains the same.

For applicants with an OP from Queensland, the Queensland Studies Authority will provide SATAC with an equivalent ATAR.

Some undergraduate courses/programs require students to have studied one or more specific Stage 2 subjects to a minimum standard in order to be eligible for selection into the course/program. These subjects are known as prerequisites.

For students completing the SACE/NTCET, in order to fulfil a prerequisite subject requirement, you must obtain a minimum grade of C- or better. The grade is used (rather than the scaled score) because the course/program administrators are interested in how well you performed in the subject itself as measured against the learning requirements of the Subject Outline.

Since prerequisites are used to determine eligibility, not rank, they do not have to contribute to the university aggregate.

Interstate/International Baccalaureate prerequisite equivalents

For students completing the International Baccalaureate in a school in Australia, or an Australian year 12 program interstate, the following table outlines the IB/interstate subject equivalents which meet prerequisite subject requirements for courses/programs in South Australia and the Northern Territory:

Interstate/IB prerequisite subject equivalents (84KB PDF)

The following grades are required for interstate/IB students to meet SA/NT prerequisite subject requirements:

State Grade
Australian Capital Territory (HSC) Scaled score of 125 or better
International Baccalaureate Grade 3 (HL) or Grade 4 (SL)
New South Wales (HSC) Performance Band 2
Queensland (QCE) S (Satisfactory) or better
Tasmania (TCE) SA (Satisfactory Achievement)
Victoria (VCE) Study Score of 25 or better
Western Australia (WACE) Scaled score of 50 or better

Assumed knowledge

Many undergraduate courses/programs recommend that commencing students have background knowledge in one or more specified SACE/NTCET Stage 1 or Stage 2 subjects or have an identified skill which will enhance the student’s understanding of the course/program content. This is known as assumed knowledge.

Assumed knowledge is not compulsory and is not used in the selection process for entry to university courses/programs. Statements of assumed knowledge are intended purely to assist students in understanding course/program content and to allow them to make subject choices which may be of benefit to them in their future tertiary studies.
