Schools are different in their value-added performance, but have no significant difference in promoting the academic
performance of students of different abilities.
Types of Differential Effectiveness
Schools are different in their value-added performance but all are more effective in promoting the academic attainment of
more able students

Stanine
A stanine is a standardized score with a mean of 5 and a standard deviation of 2. They range from 1 to 9. There are two kinds of stanines,
(a) School intake: To categorize schools into groups with a similar intake, the average AAI was calculated of all students in all schools at the S5 level and the average core 3 was calculated of all students in all schools at the S7 level.
(b) School value-added estimates: To categorize schools into groups with similar value-added
