Here is ODE's explanation of what the State School Report Card means, and what it's used for:
"Ohio School Report Cards give your community a clear picture of the progress of your district and schools in raising achievement and preparing students for the future. The information measures district and school performance in the areas most critical to success in learning. Ohio School Report Cards data shows educators, school administrators and families where their schools are succeeding as well as areas where they need to improve.
Community schools that serve a majority of their students through dropout prevention and recovery programs receive this report card. Rather than A-F grades, dropout prevention and recovery schools receive one of the following ratings for report card measures – Exceeds Standards, Meets Standards, Does Not Meet Standards or Not Rated (used when there are too few data to issue a rating).
