The College and Career Readiness and Success Center and the Midwest Comprehensive Center (both operated by AIR) completed a literature review that examined the relationship between potential postsecondary readiness measures for Iowa to consider for accountability and the student outcomes identified in the state’s definition of postsecondary readiness. They also conducted a scan of the postsecondary readiness measures included in other states’ Every Student Succeeds Act (ESSA) plans. The goal of the project was to use the literature review and the state scan to coach the Iowa Department of Education in developing a postsecondary readiness indicator for its ESSA plan.
