There is no final consensus regarding which covariates should be used (in addition to prior achievement) when estimating value-added (VA) scores to evaluate a school's effectiveness. Therefore, we examined the sensitivity of evaluations of schools' effectiveness in math and language achievement to covariate selection in the applied VA model. Four…

Although existing research suggests that students benefit on a range of outcomes when they enroll in early algebra classes, policy efforts that accelerate algebra enrollment for large numbers of students often have negative effects. Explanations for this apparent contradiction often emphasize the potential role of teacher and peer effects, which…

Schools of education are often criticized for not effectively preparing teacher candidates and teacher education research has been criticized for lack of rigor in examining the impact on student learning. Teacher preparation accrediting agencies have responded with requirements for programs to demonstrate the effectiveness of their graduates based…

Panel or grouped data are often used to allow for unobserved individual heterogeneity in econometric models via fixed effects. In this paper, we discuss identification of a panel data model in which the unobserved heterogeneity both enters additively and interacts with treatment variables. We present identification and estimation methods for…

This study was designed to assess the impact of providing teachers and principals with performance feedback on instructional practice, principal leadership, and student achievement. The teacher and principal performance feedback that was the focus of the study's intervention incorporated promising features of educator performance measures…

We examine the relationship between absenteeism and achievement since the onset of COVID-19. Applying first-differences models to North Carolina administrative data, we estimate that each absence was associated with a 0.0032 standard deviation (SD) decline in math achievement in 2022-23. As students averaged 3.3 more absences in 2022-23 than…

We estimate the effects of accountability-driven school closure in New York City on students who attended middle schools that were closed at the time of closure and students who would have likely attended a closed middle school had it remained open. We find that students who would have entered the closed school had it not closed attended schools…

The purpose of this study was to understand how a school-based personalized learning approach can help improve literacy achievement among middle grades students in a rural area. This study followed two cohorts of schools serving students in grades 6-8 in northeast Tennessee for one year each (2018-19 and 2021-22), to assess student and school…

It is widely believed that the teacher is one of the most important factors influencing a student's success at school. In many countries, teachers' salaries and promotion prospects are determined by their students' performance. Value-added models (VAMs) are increasingly used to measure teacher effectiveness to reward or penalize teachers. The aim…

Recognizing the limitations of the existing frameworks and models applied to estimate the learning loss caused by COVID-19 across the world by different studies, and the urgent need for estimating such loss at the different education levels, this paper, employs the Education Value Chain Analysis ( EVCA) approach as a new paradigm, attempts to…

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…

Researchers using VAM (Value-Added Models) methods have found that student achievement is substantially impacted by both schools and teachers. However, most of this work has been conducted within the context of the United States. Information is lacking about the educational system in China. This first study examines methodological concerns…

We apply "value-added" models to estimate the effects of teachers on an outcome they cannot plausibly affect: student height. When fitting the relatively simple models that are widely used in educational practice to New York City data, we find the standard deviation of teacher effects on height is nearly as large as that for math and…

Charter schools represent an increasingly important form of school choice in the United States. Charter schools are public schools, with a difference. Compared to traditional public schools, they are exempted from some of the state laws and regulations that govern traditional public schools. In this way, parents come to have a greater number of…
