All states in Australia used some form of TER in the 1970s onwards, based upon an aggregated scaling procedure that differed in each jurisdiction.
[3][4] Although directly equivalent to the Equivalent National Tertiary Entrance Rank (ENTER) in Victoria, and the Universities Admission Index (UAI) in New South Wales and later adopted in the Australian Capital Territory, the terms ENTER and UAI were only used in their respective states or territories.
The TER was accumulated by the South Australian Tertiary Admissions Centre (SATAC) for students who successfully completed the South Australian Certificate of Education (SACE) or the Northern Territory Certificate of Education (NTCE) and fulfilled other criteria to qualify for a TER.
The tertiary entrance aggregate was calculated as the sum of the best five Level 5 TCE subject scores, of which a maximum of two could be selected from Year 11.
As the WACE qualification was being revised for from 2005 to 2009, the process for calculating the TER for WA students was changed for tertiary entry in 2009.
