Over the past decade, many states enacted substantial reforms to teacher-related laws and policies. In Michigan, the state legislature implemented requirements for teacher evaluation based partly on student achievement, reduced tenure protections, and restricted the scope of teacher collective bargaining. Some teacher advocates view such reform as a “war on teachers,” but proponents argue these policies may have enabled personnel decisions that positively impact student performance. Evidence on this debate remains limited. In this study, we use detailed administrative data from all Michigan traditional public schools from 2005–06 to 2014–15. We estimate event study models exploiting the plausibly exogenous timing of collective bargaining agreement expirations. Across a variety of samples and specification checks, we find these reforms had generally null results, with some evidence of heterogeneity by cohort. We investigate several possible mechanisms and conclude that districts with more restrictive teacher contracts prior to reform and districts with more rigorous use of teacher evaluations experienced more positive impacts after reform exposure.

We examine the characteristics of schools preferred by parents in New Orleans, Louisiana, where a “portfolio” of school choices is available. This tests the conditions under which school choice induces healthy competition between public and private schools through the threat of student exit. Using unique data from parent applications to as many as eight different schools (including traditional public, charter, and private schools), we find that many parents include a mix of public and private schools among their preferences, often ranking public schools alongside or even above private schools on a unified application. Parents who list both public and private schools show a preference for the private sector, all else equal, and are willing to accept lower school performance scores for private schools than otherwise equivalent public options. These parents reveal a stronger preference for academic outcomes than other parents and place less value on other school characteristics such as sports, arts, or extended hours. Public schools are more likely to be ranked with private schools and to be ranked higher as their academic performance scores increase.

We analyze patterns of teacher attrition from charter schools and schools in the traditional public sector. Using rich data on students, teachers, and schools in Florida, we estimate teacher effectiveness based on repeated test scores reported at the student level for each teacher over time. Among all teachers, those in charter schools appear more likely to exit the profession than those in the traditional public sector, and in both sectors the least effective teachers are more likely to exit than their more effective counterparts. Few of these relationships appear evident for within- or between-district transfers, and there are no differential relationships between effectiveness and attrition in the charter sector. We interpret these results as indicating that whatever administrative or organizational differences may exist in charter schools, they do not necessarily translate into a discernible difference in the ability to dismiss poorly performing teachers.
