What are "Similar Districts?"
The studies presented here have compared district results not only to all Ohio school districts, but also to what are called by the Ohio Department of Education as "Similar Districts."
Each year, the ODE sources basic demographic data for each district (median income, percent disadvantaged, average education level, percent administrative professional employment, school enrollment, etc.) and clusters each school district within these measures.
Each district is then compared to all other districts, and a list of "similar districts" is generated. There are a maximum of 20 "similar districts" for each school district, with some of the districts having fewer "similar districts" due to their demographic profiles.
