Student Growth Percentiles (SGPs) increasingly are being used in the United States for inferences about student achievement growth and educator effectiveness. Emerging research has indicated that SGPs estimated from observed test scores have large measurement errors. As such, little is known about "true" SGPs, which are defined in terms…

Educator performance evaluation systems are a potential tool for improving student achievement by increasing the effectiveness of the educator workforce. For example, recent research suggests that giving more frequent, specific feedback on classroom practice may lead to improvements in teacher performance and student achievement. This report is…

Many public school districts struggle with the federal and state charge to increase student achievement while continuing to build the instructional capacity of classroom teachers. While this charge may not seem to be unreasonable, the widening achievement gap between various student subgroups as evidenced in standardized testing results presents…

Teacher observations have become a national education phenomenon, mandated by federal policies and promoted by philanthropists. They are crucial components of teacher evaluation systems that often have high stakes for teachers and school systems, but have sparked little innovation. Recent calls to make teacher evaluations better, faster, and…

Teacher value-added models (VAMs) must isolate teachers' contributions to student achievement to be valid. Well-known VAMs use different specifications, however, leaving policymakers with little clear guidance for constructing a valid model. We examine the sensitivity of teacher value-added estimates under different models based on whether they…

The purpose of this study was to investigate the relationship between the TVAAS growth score given by the Tennessee Department of Education and the overall Tennessee Educator Assessment Model (TEAM) observation rating for teachers in grades 3 through 8. The participating county public school system for this study is located in Northeast Tennessee.…

Despite policy efforts to encourage multiple measures of performance in newly developing teacher evaluation systems, practical constraints often result in evaluations based predominantly on formal classroom observations. Yet there is limited knowledge of how these observational measures relate to student achievement. This article leverages the…

This paper investigates the validity of a national, standards-based teacher evaluation programme by examining the relationship between teachers' evaluation results and their students' learning progress. We used census achievement data that assessed the same cohort of students at the end of 8th and 10th grade. We applied multilevel modelling and…

Drawing on national and state assessment datasets in reading and math, this study tested "external" versus "internal" standards-based education models. The goal was to understand whether and how student performance standards work in multilayered school systems under No Child Left Behind Act of 2001 (NCLB). Under the…

No matter how well an educator evaluation system is designed, it can only be as effective as those who are actually implementing it in the trenches (Stronge, 1993). Unfortunately, many educational reforms at the school level have entirely failed or have failed to be implemented as designed. While much of the current educator evaluation research is…

In accordance with the federal No Child Left Behind (NCLB) law of 2001, 100% of students were expected to become proficient on state assessments of reading and mathematics by the end of 2013-2014 academic year. Schools that consistently failed to meet the NCLB's Adequate Yearly Progress requirements were subject to penalties. In 2011, the U.S.…

Observational methods are increasingly being used in classrooms to evaluate the quality of teaching. Operational procedures for observing teachers are somewhat arbitrary in existing measures and vary across different instruments. To study the effect of different observation procedures on score reliability and validity, we conducted an experimental…

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…

Teacher evaluation is currently a major policy issue at all levels of the K-12 system driven in large part by current US Department of Education requirements. The main objective of this study is to explore the patterns of relationship between observational scores and value-added measures of teacher performance in math classrooms and the variation…
