A Correlated Random Effects Model for Nonignorable Missing Data in Value-added Assessment of Teacher Effects
Abstract. Value-added models have been widely used to assess the contributions of individual teachers and schools to students’ academic growth based on longitudinal student achievement outcomes. There is concern, however, that ignoring the presence of missing values, which are common in longitudinal studies, can bias teachers’ value-added scores. In this article, a flexible correlated random ef...
متن کاملModels for Value-Added Modeling of Teacher Effects.
The use of complex value-added models that attempt to isolate the contributions of teachers or schools to student development is increasing. Several variations on these models are being applied in the research literature, and policy makers have expressed interest in using these models for evaluating teachers and schools. In this article, we present a general multivariate, longitudinal mixed-mod...

This study examines the theoretical and practical implications of ranking teachers with a one-dimensional metric when teacher effectiveness varies across subjects or student types. We document the empirical failure of standard value-added assumptions of teacher input homogeneity, but demonstrate that previously suggested teacher firing policies still improve student welfare, although they resul...

متن کاملTeacher Effects as a Measure of Teacher Effectiveness: Construct Validity Considerations in TVAAS (Tennessee Value Added Assessment System)
This paper examines the validity of measures of teacher effectiveness from the Tennessee Value Added Assessment System (TVAAS). Specifically, we consider the following claims regarding teacher effects: that they adequately capture teachers' unique contributions to student learning; that they reflect adequate standards of excellence for comparing teachers; that they provide useful diagnostic inf...
