18 Calculating Progress 8 – fewer than 8 subjects examples are for illustration purposes only Example 3:  The student's weighted total is 31 points  Divide this total by 10 to get the Attainment 8 score  31 ÷ 10 = 3.1  This student's average attainment is a touch above an E grade across 8 subjects  Assume the average KS4 attainment for students with a similar KS2 performance is 3.0 points  Progress 8 is the difference between the actual score and the expected score  Actual = 3.1, expected = 3.0.
