In 2017 Georgia instituted a flexibility policy through which school districts enter into performance contracts with the state that grant districts waivers from state rules and allow schools and districts greater autonomy. In exchange, schools and districts must meet academic performance targets. The performance contracts are intended to incentivize innovations that increase student achievement. Between 2008/09 and 2016/17, 178 of Georgia's 180 districts entered into a performance contract. The Georgia Department of Education (GaDOE) wants to learn about districts' experiences with the flexibility policy, including how districts are using waivers to implement innovations, the relationship between waivers and student achievement, and whether that relationship varies by district characteristics. The study examined how student achievement changed after districts adopted a performance contract, compared with changes in the same years for districts that did not adopt one. The study used GaDOE administrative data from 2008/09 through 2017/18, publicly available data from the U.S. Department of Education, and data that GaDOE collected from surveys and interviews of district leaders. Methods used include descriptive statistics, longitudinal regression analysis, and qualitative analysis of interview data. [For the full report, see ED609818; for the appendixes, see ED609822.]
