The final Every Student Succeeds Act (ESSA) accountability regulations were issued November 2016. Draft regulations were released in the Spring 2016, and the Department of Education received comments and feedback from over 21,000 individuals and organizations. The final regulations provide specific details regarding the implementation timeline, identifying and intervening in low performing schools and schools where subgroups of students are low performing, requirements for school report cards, and the specific indicators that must be included in a state's accountability system, including the "fifth indicator" of school quality. The regulations make clear that most decisions are left to the state and local education agencies, but they emphasize the requirement of stakeholder engagement in the development of state and local plans. This article summarizes the final ESSA accountability regulations and focuses on four main issues: (1) the implementation timeline; (2) required data reporting on school report cards; (3) state accountability systems; and (4) school improvement plans.
