The Michigan School Accountability Scorecard is the state's school accountability rating. Ratings are based on test scores, student academic growth, graduation rates, attendance rates, educator evaluations, and compliance with state law. The Michigan School Accountability Scorecard uses a five-color coded system (Green, Lime, Yellow, Orange, and Red) to indicate the performance of schools. Green is highest and indicates that most of the goals were met for a school, while red is lowest and indicates that few objectives were met at a school.
