In this report, the authors examined the elimination of teacher tenure in Florida to better understand how job protections for teachers affect students. The authors focus on identifying the effect of removing tenure as part of Florida's 2011 Student Success Act on student outcomes, and in particular the effect if this legislation on student achievement. They take a quasi-experimental research approach by comparing the effect of teachers' relative exposure to tenure reform on changes in individual students' test scores after versus before the policy. The authors find limited and circumstantial evidence that Florida's tenure reform "slightly" increased student test achievement in math and reading, and that the gains were more prominent for the lowest-performing students. Specifically, the authors look across schools where faculties were most versus least vulnerable to Student Success Act provisions -- measured in two different ways -- and find that students in the most vulnerable schools show gains that compared favorably to students in the least vulnerable schools, but by a very small degree.
