Morgan, Hodge, Trepinski, and Anderson (2014) have written an article that continues to confirm what we have known for some time-teacher effects on student achievement have limited stability. In this commentary, we address the other potential contributions this work can make to inform practice, policy, and research. While illustrating Morgan et…

This study examines one part of a validity argument for portfolio assessments of teaching practice used as an indicator of teaching quality to inform a licensure decision. We investigate the relationship among portfolio assessment scores, a test of teacher knowledge (ETS's Praxis I and II), and changes in student achievement (on…

There is increasing policy interest in the use of standards-based multiple measure teacher evaluation systems that include both observational and value-added measures of teacher effectiveness. The growing literature that assesses the relationships between these measures does so mainly in academic settings using a validity lens. While valuable in…

This study examined the SAS Education Value-Added Assessment System (EVAAS®) in practice, as perceived and experienced by teachers in the Southwest School District (SSD). To evaluate teacher effectiveness, SSD is using SAS EVAAS® for high-stakes consequences more than any other district or state in the country. A mixed-method design including a…

The context for education policy making has changed dramatically in recent years. Policymaking at the state-level has become characterized by near-unprecedented enactment of neo-liberal education policies, increased influence of so-called Education Reform Advocacy Organizations (ERAOs) and increased challenges to unions' political influence.…

The No Child Left Behind (NCLB) Act of 2001 required all schools, including those located in historically disadvantaged areas, to employ highly qualified teachers. Schools in areas with higher levels of poverty and students of color have historically employed a higher percentage of less qualified teachers (Clotfelter, Ladd, & Vidgor, 2005,…

The last five to ten years has seen a renewed interest in the stability of teacher behavior and effectiveness. Data on teacher performance and teacher effectiveness are being used increasingly as the basis for decisions about continued employment, tenure and promotion, and financial bonuses. The purpose of this study is to explore the stability of…

This study focuses on pre-service teachers' perspectives regarding how the process of completing the Performance Assessment for California Teachers (PACT) affected them academically, professionally, and personally. Two cohorts participated in this year-two study. Pre-service teachers' perspectives were acquired using a survey instrument…

Developing teaching practices that meet the needs of Second Language Learners (SLL) calls for models of apprenticeship in which teacher candidates acquire competency on how to create learning spaces where students discover, experience and construct knowledge rather than solely practicing skills. The aforesaid argument has an implication when…

In this manuscript, the guest editors of the EPAA Special Issue on "Value-Added Model (VAM) Research for Educational Policy" (1) introduce the background and policy context surrounding the increased use of VAMs for teacher evaluation and accountability purposes across the United States; (2) summarize the five research papers and one…

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…

Accountability in education has prompted policy makers and practitioners to focus on data use for instructional and organizational decision-making. The popular media have seized on Value Added (VA) measures as a key type of data use for reforming U.S. schools. Among education researchers, however, there are both critics and proponents. We examined…

If teacher value-added estimates (VAEs) are to be used as indicators of individual teacher performance in teacher evaluation and accountability systems, it is important to understand how much VAEs are affected by the data and model specifications used to estimate them. In this study we explored the effects of three conditions on the stability of…

The authors of the study "The Long-Term Impact of Teachers" claim that their study shows that increases in teacher value-added lead to significant and lasting increases in test scores and significant increases in income that will last throughout adulthood. Instead, I show that these claims are false because they are contradicted by the…

A growing number of states and local schools across the country have adopted educator evaluation and accountability programs based on the use of student test scores and value-added models (VAM). A wide array of potential legal issues could arise from the implementation of these programs. This article uses legal analysis and social science evidence…
