Year 10 unit scores 80 % rule course scores AST + Best 3. 6

80 % rule For a minor 80. 1, 70. 8 x 2. 0 std

80 % rule For a 4. 0 unit major 80. 1, 70. 8, 75.

What is the AST? • AST - ACT Scaling Test • A test attempted

Course Scaling Calculations

Year 10 unit scores 80 % rule course scores AST + Best 3. 6 majors OCS process UAI Tertiary Studies

80 % rule For a minor 80. 1, 70. 8 x 2. 0 std units = 1. 6 std units ie course score will be 1 x 80. 1 plus 0. 6 x 70. 8 42. 5 = 122. 6/1. 6 = 76. 6

80 % rule For a 4. 0 unit major 80. 1, 70. 8, 75. 0 & 68. 0 0. 8 x 4. 0 std units = 3. 2 std units ie course score will be 1 x 80. 1 plus 1 x 75. 0 plus 1 x 70. 8 plus 0. 2 x 68. 0 13. 6 = 239. 5/3. 2 = 74. 8

What is the AST? • AST - ACT Scaling Test • A test attempted by all ACT Year 12 students wishing to obtain a University Admissions Index (UAI). i. e. All students studying ‘T’ packages. • Measures a range of general skills considered to be relevant to success in a variety of courses at university. • Used as a moderating device between courses and across colleges

Step 4: Recalculation of Scaled Scores From calculations involving each course separately new multiplying and adding factors are found. A new scaled score is then calculated using these parameters. The new scaled score is calculated once again from the raw score.

To calculate the Tertiary Entrance Score (TES) Take the best 3. 6 ie 3 best majors plus either 0. 6 of a major or a whole minor. 0. 6 x 175 195 Physics 192 Maths 176 105 IT Art 668 TES

The ranking of this score against all other scores gives a Tertiary Entrance Rank (TER). The University Admission Index (UAI) is obtained by combining the cohort who completed a Tertiary package and the age cohort of the same students who started Year 10. TES 668 UAI 97. 0
