Value-added metrics or models (VAMs) are an important component of the teacher evaluation process that evaluators use to determine the value teachers add to their students' academic achievement. VAMs are used to arrive at a score that is derived from the number of the teachers' students who pass and/or fail a standardized assessment. While prior…

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…

Existing research on "school effectiveness" indicates that differences at the school level contribute significantly towards variation in student outcomes; however, less is known about the effectiveness of schooling in low- and middle-income countries (LMICs). This paper addresses this gap using quantitative analysis of data from two…

This study advances our understanding of the relationships among the different elements of a teacher evaluation model and its usefulness in predicting student learning. Important questions arise about teacher evaluation systems, including (a) the magnitude of correlations among the sources of evidence used for identifying teacher effectiveness and…
