The Michigan Department of Education (MDE) ranks schools past on test scores and than reports the percentile a schools is in. This tells us the absolute performance, but leaves out information. For example, the percentage of students getting free lunches greatly impacts performance. A school that has a lot of free lunch students that beats expectations, could be adding more value than a school with high absolute performance. I’ve created a map that shows under and over performing schools based on location, demographics, and socio-economic status. The model captures the top 10% and the bottom 10%.
