In this article, we explain how overly prescriptive, rigid state statutory and regulatory policy frameworks regarding teacher evaluation, tenure and employment decisions outstrip the statistical reliability and validity of proposed measures of teaching effectiveness. We begin with a discussion of the emergence of highly prescriptive state…

Leadership matters. Principals are the primary drivers of school improvement and the best long-term investment to ensure effective teaching and learning at scale. Principals are central to State efforts to implement new college and career-ready standards, execute teacher evaluation and support systems and turn around low-performing schools. These…

This article reports on how states strive to overhaul their teacher tenure policies. Over the past year, a handful of states have begun to overhaul their tenure-granting processes by increasing the number of years it takes teachers to win due process rights, and by trying to improve the evaluations that are supposed to guide determinations of…

With the conclusion of the second round of the federal Race to the Top competition, states across the country--winners and losers alike--are vowing to move forward with ambitious plans to reshape teacher-evaluation systems, fix struggling schools, revamp antiquated data systems, and make other changes aimed at raising student achievement. Yet…

The modernization of teacher evaluation systems, an increasingly common component of school reform efforts, promises to reveal new, systematic information about the performance of individual classroom teachers. Yet while states and districts race to design new systems, most discussion of how the information might be used has focused on traditional…

Research continues to find large differences in student achievement gains across teachers' classrooms. The variability in teacher effectiveness raises the stakes on identifying effective teachers and teaching practices. This paper combines data from classroom observations of teaching practices and measures of teachers' ability to improve student…

Amid the cacophony of special interests fighting to be heard in statehouses and on Capitol Hill, a cadre of current and former chief state school officers is elbowing its way into the nation's education debate at a time when states are taking more control of K-12 education. A little more than a year old, Chiefs for Change is an invitation-only…

This publication describes new ways that States redesigning their educator effectiveness systems are measuring growth in student achievement, including value-added models and student learning objectives. The publication concludes with a brief discussion of communicating the results of student growth measures, such as monitoring correlations…

The content of this guide was derived from ongoing work of a working group on growth models coordinated and facilitated by the SLDS Grant Program's State Support Team. The Statewide Longitudinal Data Systems (SLDS) Grant Program was asked by several states to review current growth models with the goal of determining the impact of different models…

Over the past decade, Ohio has made important education policy advances, with a focus on student learning and achievement, standards, and accountability. Ohio is serious about its commitment to quality schools and honors this commitment by providing Local Education Agencies (LEAs) a research-based, transparent, fair teacher evaluation system…

Peer Assistance and Review (PAR) is a local labor-management initiative designed to improve teacher quality. In PAR, expert "consulting teachers" mentor, support, and evaluate novice and underperforming veteran teachers. Evaluations under PAR can lead to dismissals. The authors examine the costs and benefits of PAR, both financial and…

A teacher's effectiveness--the most important factor for schools in improving student achievement--is not measured, recorded, or used to inform decision making in any meaningful way. The failure of evaluation systems to provide accurate and credible information about individual teachers' instructional performance sustains and reinforces a…

This report examines the pervasive and longstanding failure to recognize and respond to variations in the effectiveness of teachers. At the heart of the matter are teacher evaluation systems, which in theory should serve as the primary mechanism for assessing such variations, but in practice tell everyone little about how one teacher differs from…

Too often, teacher evaluations haven't provided enough information to spur improvement in teaching. The vast majority of teachers in any school, district, or state are rated above--sometimes well above--average. The feedback that teachers do receive is often not specific enough to help them improve. In this article, Morgaen Donaldson explores some…
