The five thoughtful papers included in this issue of "Educational Researcher" ("ER") raise new questions about the use of value-added methods (VAMs) to estimate teachers' contributions to students' learning as part of personnel evaluation. The papers address both technical and implementation concerns, considering potential…

This brief summarizes a 2019 study of educator supply, demand, and quality in North Carolina conducted by the Learning Policy Institute in collaboration with the Education Policy Initiative at Carolina and WestEd. That study supported the state's ongoing efforts to meet the standard set in the North Carolina Supreme Court's decision in…

For years now, educators have looked to international tests as a yardstick to measure how well students from the United States are learning compared with their peers. The answer has been: not so well. The United States has been falling further behind other nations and has struggled with a large achievement gap. Federal policy under No Child Left…

Using five AERA presidential addresses over the past half century as landmarks, this essay traces the evolution of research on teaching and teacher education as well as some critical impacts the research has had on policy and practice related to teacher education and teacher evaluation in the United States. The discussion shows how these addresses…

One of the failings of teacher evaluation systems in the United States has been their reliance on the school principal alone as the person expected to observe teachers, mentor those who struggle, document concerns and processes, and make the final call on whether to recommend dismissal. Given the enormous scope of their duties, it's simply…

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…

Efforts to improve teacher education have recently focused in on the importance of well-supervised clinical practice as a critical element of effective preparation. This article outlines the challenges to creating productive clinical experiences for prospective teachers, and identifies strategies that have been found successful in confronting…

Teacher evaluation systems are being overhauled by states and districts across the United States. And, while intentions are admirable, the result for many new systems is that good--often excellent--teachers are lost in the process. In the end, students are the losers. In her new book, Linda Darling-Hammond makes a compelling case for a…

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…

As teachers who care deeply about the quality of their own teaching and the development of teaching as a profession, the authors write this article from their conviction that performance assessments in teaching are a critical strategy for developing teachers' expertise and for improving the quality of teacher preparation. They note that the…

The Performance Assessment for California Teachers (PACT) is an authentic tool for evaluating prospective teachers by examining their abilities to plan, teach, assess, and reflect on instruction in actual classroom practice. The PACT seeks both to measure and develop teacher effectiveness, and this study of its predictive and consequential…

As teaching has become a major focus, teacher evaluation is currently the primary tool being promoted to improve it. Thus, most states are dramatically overhauling their evaluation systems for teachers and administrators. What we really need is the conception of teacher evaluation as part of a teaching and learning system that supports continuous…

Virtually everyone agrees that teacher evaluation in the United States needs an overhaul. Existing systems rarely help teachers improve or clearly distinguish those who are succeeding from those who are struggling. The tools that are used do not always represent the important features of good teaching. Criteria and methods for evaluating teachers…

The objectives of the meeting were to: (1) Identify and discuss recent advances in the use of value-added models (VAMs) and student growth…
