Our school system is utilizing the MISA (from Pro Ed) as a pre and post measure of ADHD interventions.
As all scales set the ''no-risk'' level at T-score 60, we set that as our goal and then measure progress using % change to goal.
For example, if the pre-test Hyperactivity T-score was 75 and the post-test T-score was 65, there has been ~66% progress toward goal.
Using the Cohen & Cohen (1983) descriptors:
1) Small (2) T-score points change
2) Medium (5) T-score points change
3) Large (8) T-score points change
4) Very Large (10+) T-score points change
...the change in T-score values is very large.
We are also linking MISA results to interventions listed in the series, Practical Ideas, also from Pro Ed.
Hope this helps.
