9th Grade Exclusion Penalty
The 9th Grade Exclusion penalty was based on the belief that: (1) there is a need for some exclusions in the 9th grade; and, (2) exclusions in the 9th grade should be kept to a minimum. Consequently, we set the penalty at 15% of the exclusion rate.
Seven hundred six districts had 9th graders. The lowest penalty was 0, and the highest penalty was 39. The Average penalty was 9.9; Half the schools had a penalty over 10.3.
