In order to comply with the regulations put forth by the Elementary and Secondary Education Act (ESEA), as amended by the Every Student Succeeds Act (ESSA), states are required to submit evidence associated with their statewide accountability systems to the United States Department of Education (ED) for peer review. Thirty-eight states submitted evidence for their assessment systems to the peer review process in 2016. As of March 2017, ED has issued thirty-six decision letters in response. Of those responses, two states, Wisconsin and Wyoming, received feedback regarding use of the ACT as their high school reading/language arts and mathematics assessments for accountability purposes. The information included in this brief outlines the findings of ED's feedback to Wisconsin and Wyoming contained in the decision letters sent to each state regarding their use of the ACT. Three appendices are included.
