There is a growing consensus that evidence of teachers' contributions to student learning should be a component of teacher evaluation systems, along with evidence about the quality of teachers' practice. Value-added models (VAMs), designed to evaluate student test score gains from one year to the next are often promoted as tools to accomplish this…

As a major policy focus, teacher evaluation is currently the primary tool promoted to improve teaching quality. But evaluation alone is not enough. What will most transform teaching quality--and the profession--is the creation of a larger system that supports teaching and learning through on-the-job evaluation and professional development, and…

There is a widespread consensus among practitioners, researchers, and policy makers that current teacher evaluation systems in most school districts do little to help teachers improve or to support personnel decision making. For this reason, new approaches to teacher evaluation are being developed and tested. There is also a growing consensus that…

Policy shapes practice, and the increasingly important realm of professional development is no exception. In order to identify effective professional development policies and strategies, a Stanford University research team examined the policy frameworks supporting high levels of professional development activity in four states. The…

Recent findings from a Mathematica study comparing the performance of teachers prepared via alternative and traditional routes have been interpreted to suggest that policymakers and practitioners should expand the use of fast-entry alternative routes and seek teachers trained through such programs, as they presumably perform as well in the…

In this multi-method case study, the authors explore the success of school reform in Milwaukee Public Schools (MPS), whose school reform combines a portfolio strategy and a managed instruction approach. Portfolio strategy is a term used to describe an approach that decentralizes resources and decision-making to school sites--increasingly in…

This study examines eight exemplary pre- and in-service principal development programs. The programs were chosen both because they provide evidence of strong outcomes in preparing school leaders and because, in combination, they represent a variety of approaches with respect to their designs, policy contexts, and the nature of partnerships between…
