In the context of Bayesian factor analysis, it is possible to compute plausible values, which might be used as covariates or predictors or to provide individual scores for the Bayesian latent variables. Previous simulation studies ascertained the validity of mean plausible values by the mean squared difference of the mean plausible values and the…

Surveys of teacher preparation program (TPP) completers have become one widely used measure for program accountability and improvement, yet there is little evidence as to whether perceptions of preparation experiences predict the workforce outcomes of teachers. In the present study, we use statewide completer survey data from North Carolina to…

Because the pandemic exacerbated chronic absenteeism in many parts of the country, the need to understand how schools can improve student attendance has never been greater. Accordingly, this study breaks new ground by examining high schools' contributions to attendance after accounting for individual students' prior absenteeism and other…

School districts across the United States increasingly use value-added models (VAMs) to evaluate teachers. In practice, VAMs typically rely on lagged test scores from the previous academic year, which necessarily conflate summer with school-year learning and potentially bias estimates of teacher effectiveness. We investigate the practical…

Background: Value-added modeling (VAM) has been used to rank teachers and assess teacher and school quality. The apparent relationship between value-added teacher rankings and gains in student performance provide a foundation for the view that the contribution of teachers to student performance is the largest factor influencing student…

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…

Papay (2011) noticed that teacher value-added measures (VAMs) from a statistical model using the most common pre/post testing timeframe--current-year spring relative to previous spring (SS)--are essentially unrelated to those same teachers' VAMs when instead using next-fall relative to current-fall (FF). This is concerning since this choice--made…

Value-added measures of educational progress have been used by education researchers and policy-makers to assess the performance of teachers and schools, contributing to performance-related pay and position in school league tables. They are designed to control for all underlying differences between pupils and should therefore provide unbiased…

This study examines the accuracy of performance ratings from the Framework for Leadership (FFL), Pennsylvania's tool for evaluating the leadership practices of principals and assistant principals. The study analyzed four key properties of the FFL: score variation, internal consistency, year-to-year stability, and concurrent validity. Score…

This "Stated Briefly" report is a companion piece that summarizes the results of another report of the same name. This study examines the accuracy of performance ratings from the Framework for Leadership (FFL), Pennsylvania's tool for evaluating the leadership practices of principals and assistant principals. The study analyzed four key…

Estimates of teacher "value-added" suggest teachers vary substantially in their ability to promote student learning. Prompted by this finding, many states and school districts have adopted value-added measures as indicators of teacher job performance. In this paper, we conduct a new test of the validity of value-added models. Using…

This article develops a validity argument for the use of the Tripod student survey of instructional practices to assess teacher effectiveness in summative teacher evaluations and professional development decisions. This paper expands upon previous research in three ways: (a) it draws from current validity thinking to examine the evidence for…

High-quality measures of instructional practice are essential for research and evaluation of innovative instructional policies and programs, as well as for providing feedback to teachers and administrators. In this study, the authors examined whether using anchoring vignettes in web-based surveys improved the validity of teachers' self-assessments…

The growing availability of data linking students to classroom teachers has made it possible to estimate the contribution teachers make to student achievement. While there is a growing consensus that teacher quality is important and current evaluation systems are inadequate, many have expressed concerns over the use of value-added measures (VAMs)…
