New Orleans schools experienced drastic reforms after Hurricane Katrina in 2005. To examine teachers' perspectives on these reforms, we surveyed 323 teachers who taught in New Orleans public schools before 2005 and in 2013-2014. Teachers directly compared the learning and work environments and student and teacher outcomes of their current schools…

Policymakers are revolutionizing teacher evaluation by attaching greater stakes to student test scores and observation-based teacher effectiveness measures, but relatively little is known about why they often differ so much. Quantitative analysis of thirty schools suggests that teacher value-added measures and informal principal evaluations are…

In the recent drive to revamp teacher evaluation and accountability, measures of a teacher's value added have played the starring role. But the star of the show is not always the best actor, nor can the star succeed without a strong supporting cast. In assessing teacher performance, observations of classroom practice, portfolios of teachers' work,…

In this mixed-methods study, we examine the degree to which district- and building-level administrators accommodate teacher-quality and test-based accountability policies in their hiring practices. We find that administrators negotiated local hiring goals with characteristics emphasized by federal and state teacher-quality policies, such as…

But would these "teacher value-added" measures help to improve student achievement? I consider the statistical validity, purposes, and costs of teacher value-added policies. Many of the key assumptions of teacher value added…

These value-added measures, the author writes, are useful for sorting out-of-school influences from school influences or from teacher performance, giving…

The development of the horse and buggy was a necessary first step toward the development of the automobile; in fact, the first cars were built by putting engines on buggies. So it is with school accountability. The failure of No Child Left Behind (NCLB) to measure school performance is well known among researchers and, to some degree, among…
