Measuring teacher effectiveness has been debated and studied for numerous years. While some progress has been made, consensus has yet to be reached regarding what it means to be an effective teacher and how to measure effectiveness. This study uses administrative data from North Carolina to assess the relationship between school principal…

In this study, we estimated the relationship between two popular measures of teacher effectiveness--teachers' value-added model (VAM) estimates, represented in this study via median growth percentiles (MGPs), and teachers' observational scores, derived from the TAP System for Teacher and Student Advancement. We examined the relationship between…

This CALDER research brief builds on pioneering research by the Measures of Effective Teaching Project (Kane et al., 2013) and Jackson (2018) to look at two measures of teacher quality-value-added measures (VAMs) for both test outcomes and non-test outcomes--and what they can tell education leaders about the teacher workforce. Both measures use a…

Teachers in 13 states are evaluated using value-added models (VAMs), a measure of student growth on standardized tests. The problem is that value-added models evaluate intermediate-level teachers' ability to have students perform on a standardized assessment despite other factors affecting students' academic performance, such as socioeconomic…

The number of years to estimate value-added measures (VAM) has received insufficient attention. Researchers often use as many years as available, to increase precision and decrease transitory sorting bias. However, this decision has little theoretical or empirical backing. We develop a theoretical framework and evaluate data from thousands of…

Local education agencies (LEAs) continue to use value-added models (VAMs) for teacher evaluation policies and purposes, often with consequences attached. Although the Every Student Succeeds Act (ESSA) provides more flexibility to LEAs, few have discontinued VAM use, suggesting they interpret VAMs as a valid measure of teacher effectiveness. In…

This paper aims to identify and compare key factors influencing US States' or an OECD country's decision to employ student test scores or test score value-added (VAM) in evaluating teacher effectiveness. Analysis using multiple linear probability model and logistic regression frameworks indicates that the use of VAM/student test scores was…

In this article, we explore whether the evaluation instruments used in the teacher selection process in Peru are good predictors of teacher effectiveness. To this end, we estimate teacher value-added (TVA) measures for public primary school teachers and test their relationship with Peru's results of two rounds of the teacher evaluation (i.e., a…

Advocates for the use of a multi-measure system of performance evaluation argue that multiple measures may better capture meaningful differences in employee effectiveness and help align effort with organizational objectives. This may be particularly important in organizations such as schools that produce multiple outcomes. In this paper I use a…

The success of many students with disabilities (SWDs) depends on access to high-quality general education teachers. Yet, most measures of teacher value-added measures (VAM) fail to distinguish between a teacher's effectiveness in educating students with and without disabilities. We create two VAM measures: one focusing on teachers' effectiveness…

The effect of remote learning on student performance has been a frequent topic of research and discussion in the aftermath of the COVID-19 pandemic, yet little is known about the impact of remote instruction on the performance of teachers. This study documents how relative effectiveness of teachers changed when moving from in-person to remote…

The success of students with disabilities (SWDs) depends on access to high-quality general education teachers. Yet, teacher value-added measures (VAMs) generally fail to distinguish between effectiveness in educating students with or without disabilities. Using data from the Los Angeles Unified School District, we create two VAMs: one focusing on…

This paper examines how different measures of teacher quality are related to students' long-run educational trajectories. We estimate teachers' "test-based" and "nontest" value-added (the latter based on contributions to student absences, suspensions, grade progression, and grades) and assess how these predict various student…

This paper proposes a new methodology for estimating teacher value-added. Rather than imposing a normality assumption on unobserved teacher quality (as in the standard empirical Bayes approach), our nonparametric estimator permits the underlying distribution to be estimated directly and in a computationally feasible way. The resulting estimates…

States are responsible for setting and evaluating the standards that teacher preparation programs (TPPs) must meet for accreditation. Despite the considerable investment that states make in this process, no prior research has linked the ratings of TPPs generated by program reviews to inservice teacher performance. In this paper, we describe…
