The purpose of this study is to investigate teacher perceptions of Value-Added Models specifically as they relate to students with disabilities. Value-Added Models are designed to reward teachers for student growth while taking into account factors such as socioeconomic status and disabilities (Weigert, 2012). The study also examines the alignment…

Every-grade, every-year testing plays a prominent part in U.S. education policy and research, but the rise of standardized testing has been met with frustration and opposition. In response, policymakers have proposed legislation designed to curb the amount of standardized testing. There is little empirical evidence, however, about the potential…

Recent corporate education reform policies have replaced relatively informal systems of principal observations that had been familiar to many teachers for much of their professional careers with high-stakes teacher evaluation (HSTE) systems that now determine who is allowed to remain in the profession and who gets terminated. Many education…

Testing organizations are faced with increasing demand to provide subscores in addition to the total test score. However, psychometricians argue that most subscores do not have added value to be worth reporting. To have added value, subscores need to meet a number of criteria: they should be reliable, distinctive, and distinct from each other and…

In the UK, USA and elsewhere, school accountability systems increasingly compare schools using value-added measures of school performance derived from pupil scores in high-stakes standardised tests. Rather than naïvely comparing school average scores, which largely reflect school intake differences in prior attainment, these measures attempt to…

Previous research has examined how subjective task-value and expectancy of success influence the appraisal of value-promoting messages used by teachers prior to high-stakes examinations. The aim of this study was to examine whether message-frame (gain or loss-framed messages) also influences the appraisal of value-promoting messages. Two hundred…

As a post-structural critique of US teacher evaluation policy, this paper aims to disrupt accepted conceptualizations of teachers by (1) identifying discursive constructions of teachers in political talk, action, and legislation; (2) unpacking the ways that these constructions operate to legitimize punitive accountability policies and practices;…

Teacher effectiveness varies substantially, yet principals' evaluations of teachers often fail to differentiate performance among teachers. We offer new evidence on principals' subjective evaluations of their teachers' effectiveness using two sources of data from a large, urban district: principals' high-stakes personnel evaluations of teachers,…

Teacher preparation programmes (TPPs) find many ways to shape the development of their teacher candidates while bridging the research to practice gap in university and school partnerships. Recently, accountability models built on high-stakes standardised student assessments (Value-Added Models [VAM]) have been mandated as a way to evaluate the…

We apply "value-added" models to estimate the effects of teachers on an outcome they cannot plausibly affect: student height. When fitting the relatively simple models that are widely used in educational practice to New York City data, we find the standard deviation of teacher effects on height is nearly as large as that for math and…

In this study, we investigated the factor structure underlying the TAP System for Teacher and Student Advancement used across the nation for increased teacher-level accountability purposes. We found evidence of poor fit based on the factor structure posited and found large correlations among dimensions, suggesting one-to-two factors with one…

Value-added models try to separate the contribution of individual teachers or schools to students' learning growth measured by standardized test scores. There is a policy trend to use value-added modeling to evaluate teachers because of its face validity and superficial objectiveness. This article investigates the potential long term consequences…

The use of student achievement data to evaluate an individual teacher's effectiveness has become a new focus in educational policy. This article focuses on the underresearched teacher perception of this new policy measure. Drawing on ethnographic research procedures, this article explores how first-grade teachers in one state navigated a new…

Educators struggle with "value-added" teacher evaluation models based on high-stakes student assessments. Despite validity and reliability threats, these models evaluate university-based teacher preparation programs (TPPs), and play a role in state and professional accreditation. This study reports a more rational value-added evaluation…

Although in plain sight daily, a highly successful war against the public schools has been hidden in the shadows of public consciousness. Only very recently have several people written articles about this war, with the only book calling it a war being written in 2002. Neither the public nor educators have become aware of the far-reaching extent…
