How are School Performance Grades Calculated? As required by state legislation, the School Performance Grades are based 80 percent on the school’s achievement score (calculated using a composite method based on the sum of points earned by a school on all of the indicators measured for that school), and 20 percent on students’ academic growth (compares the actual performance of the school’s students to their expected performance based on their prior testing performance). There is an exception to this. If a school meets expected growth but inclusion of the school’s growth reduces the school’s performance score and grade, a school may choose to use the School Achievement Score only to calculate the performance score and grade. The final grade will be based on a 15-point scale this year, per legislation.
