School grades provide an easily understandable metric to measure the performance of a school. Parents and the general public can use the informational baseline school grade and its associated components to understand how well each school is serving its students. The school grades calculation was revised substantially for the 2014-15 school year to implement statutory changes made by the 2014 Legislature and incorporate the new Florida Standards Assessments (FSA). The 2014-15 school grades provide a baseline calculation for informational purposes that schools can use to improve in future years. The purpose of this technical guide is to provide a description of the procedures used to determine school grades for the 2014-15 school year as set forth in Rule 6A-1.09981, Florida Administrative Code (F.A.C.), and Section 1008.34, Florida Statutes (F.S.). This guide does not replace or supersede the rule or statute and is intended to provide the reader with an explanation of the methodology for establishing grades as set forth in rule and statute. The 2014-15 changes to the school grading system refocus the school grading formula on student success measures: (1) achievement; (2) learning gains (beginning in 2015-16); (3) graduation; (4) acceleration success; and (5) maintaining a focus on students who need the most support.
