How the UAI is calculated? This powerpoint presentation shows the relationship between course scores, AST results and UAI

Step 1: This is an example of a student’s possible Raw scores for each Tertiary course and their AST results MathsEnglishPhysicsITArtAST Raw Score

Step 2: Multiply each raw course score by 2 and add 10 to get an initial scaled score MathsEnglishPhysicsITArtAST Raw Score Scaled Score

Step 3: Calculate Initial Vi or Scaling Score Average of best 3.6 course scores plus 0.2 of AST MathsEnglishPhysicsITArtAST Raw Score Scaled Score best major course scores:194Physics 190Maths 180IT Plus 0.6 of next best major or minor x Art Plus 0.2 x AST total:703 divide total by 3.8:185Vi (1 st scaling run)

Step 4: Recalculation of Scaled Scores From calculations involving each course separately new multiplying and adding factors are calculated using the data from all colleges. A new scaled score is then calculated from the raw scores using these parameters. Add Multiply MathsEnglishPhysicsITArtASTVi 1 st Raw Score Scaled Score Scaled Score 2 192* *90 x = 192

Step 5: Calculate a new Vi (2 nd scaling run) Average of the best 3.6 courses (scaled score 2) plus 0.2 of AST 3 best major course scores:195Physics 192Maths 176IT Plus 0.6 of next best major or minor x Art Plus 0.2 x AST total:705 divide total by 3.8:186 Vi (2 nd scaling run)

….and so the process continues until the scaled scores stop changing. MathsEnglishPhysicsITArtASTVi (final) Raw Score Scaled Score

To calculate the Tertiary Entrance Score (TES): Take the best 3.6 final scaled course scores ie 3 best majors plus either 0.6 of next best major or minor. 3 best major course scores:195Physics 192Maths 176IT Plus 0.6 of next best major or minor x Art TES:668

The ranking of this score against all other scores gives a Tertiary Entrance Rank (TER) (e.g. 668). The University Admission Index (UAI) (e.g. 97.0) is obtained by combining the cohort who completed a Tertiary package and the age cohort of the same students who started Year 10.
