School value-added models are widely applied to study, monitor, and hold schools to account for school differences in student learning. The traditional model is a mixed-effects linear regression of student current achievement on student prior achievement, background characteristics, and a school random intercept effect. The latter is referred to…

California is one of just two states (with Kansas) that does not use a student-level growth model to measure school performance. This brief lays out a number of common beliefs about growth models and provides evidence that these beliefs are inaccurate or unsupported. In so doing, the brief makes a positive case that the state should adopt such a…

Nations, states, and districts must choose among an array of different approaches to measuring school effectiveness in implementing their accountability policies, and the choice can be difficult because different approaches yield different results. This study compares two approaches to computing school effectiveness: a "beating the odds"…

Education systems focus on issues related to school effects and differences. School effects are used as a basis for accountability in various countries including China. This study investigated the stability and cross-disciplinary consistency of value-added estimates based on student scores in selected schools in a city in central China. The…

Background/Context: Closing achievement gaps is a major concern in U.S. education. These gaps can develop in a wide range of ways over the course of a student's schooling. Yet, research on school effectiveness and accountability policies for schools often focuses on rank orderings of schools based on value-added models, which could mask those…

State and federal accountability policies are predicated on the ability to estimate valid and reliable measures of school impacts on student learning. The typical spring-to-spring testing window potentially conflates the amount of learning that occurs during the school year with learning that occurs during the summer. We use a unique dataset to…

Value-added estimates of teacher or school quality are increasingly used for both high- and low-stakes accountability purposes, making understanding of their limitations critical. A review of the recent value-added literature suggests three concerns with the state of the research. First, the issues receiving the most research attention have not…

In recent decades, school performance ranking (or 'league table') have become a common feature of many education systems in the world. The ranking is usually published by government and news agencies in an attempt to measure and compare the relative performance of individual schools against a number of criteria, including academic performance.…

This technical report is one of a series of four technical reports that describe the results of a study comparing eight alternative models for estimating school academic achievement using data from the Arizona, North Carolina, Oregon, and Pennsylvania accountability systems. The purpose of these reports was to evaluate a broad range of models…

School value-added studies have largely demonstrated the effects of socioeconomic and demographic characteristics of the schools and the pupils on performance in standardised tests. Traditionally, these studies have assessed the variation coming only from the schools and the pupils. However, recent studies have shown that the analysis of academic…

One outcome of the implementation of No Child Left Behind Act of 2001 and its call for better accountability in public schools across the nation has been the use of student assessment data in measuring schools' effectiveness. In general, inferences about schools' effectiveness depend on the type of statistical model used to link student assessment…

This study examines the effects of the summer period on value-added assessment (VAA) of teacher and school performance at the early grades. The results indicate that 40-62% of the variance in VAA estimates originates from the summer, depending on the outcome. Furthermore, when summer is omitted from the VAA model, 51-61% of the teachers and 58-61%…
