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…

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…

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…

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…

In this study, researchers compared the concordance of teacher-level effectiveness ratings derived via six common generalized value-added model (VAM) approaches including a (1) student growth percentile (SGP) model, (2) value-added linear regression model (VALRM), (3) value-added hierarchical linear model (VAHLM), (4) simple difference (gain)…

Value-added (VA) modeling can be used to quantify teacher and school effectiveness by estimating the effect of pedagogical actions on students' achievement. It is gaining increasing importance in educational evaluation, teacher accountability, and high-stakes decisions. We analyzed 370 empirical studies on VA modeling, focusing on modeling and…

This study introduces the signal weighted teacher value-added model (SW VAM), a value-added model that weights student-level observations based on each student's capacity to signal their assigned teacher's quality. Specifically, the model leverages the repeated appearance of a given student to estimate student reliability and sensitivity…

This study investigated teacher evaluation practices used in Indiana as the state was implementing a mandated teacher evaluation system (Public Law 90) and early reporting of subsequent teacher effectiveness results by the Indiana Department of Education. The study surveyed public school administrators: (a) superintendents, (b) special education…

Districts nationwide have increased the frequency of teacher evaluations. Yet, we know little about the role of evaluator feedback for teacher improvement. Using unique classroom observation-level data, we use evaluator ratings and teacher self-assessments of teacher performance to rigorously examine (positive and negative) feedback valence from…

The majority of states include value-added models (VAMs) or some other measure of student academic growth as a component of their teacher evaluation systems. However, there is considerable disagreement among researchers about whether states and school districts should use student growth measures to make high-stakes personnel decisions. Many…

Research shows that assuming a test scale is equal-interval can be problematic, especially when the assessment is being used to achieve a policy aim like evaluating growth over time. However, little research considers whether teacher value added is sensitive to the underlying test scale, and in particular whether treating an ordinal scale as…

States are incorporating evaluation ratings into new, multioutcome teacher preparation program (TPP) evaluation systems, yet little is known about the relationships between TPPs and the evaluation ratings of program graduates. To address this gap, we use teachers' ratings on the North Carolina Educator Evaluation System to determine whether TPPs…

Responding to an Illinois law that took effect in 2010, the Performance Evaluation Reform Act (PERA), Chicago Public Schools (CPS) created and implemented the REACH (Recognizing Educators Advancing Chicago's Students) educator evaluation and support system. REACH was piloted in 2012-13. It is still being implemented as of the 2019-20 school year…

This action research study examined the relationship between teacher performance and student achievement in reading language arts and mathematics. The study sought to determine if teacher evaluation methods used to determine teacher performance, had a relationship in improving student achievement. The researcher investigated the topic using…

This research examines empirically the relationship between two measures of teacher quality: one based on professional standards and a second one using teacher value-added estimates. It also studies the extent to which teacher observable characteristics, such as teacher training variables, are associated to better performance on either of these…
