Identifying the Over and Under Achieving Michigan Schools

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%.

OverperformingIndicates a school that over performed on one or more of math, reading, science
