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…

When the COVID-19 pandemic hit the U.S. last spring, schools nationwide shut their doors and states cancelled annual standardized tests. Now federal and state policymakers are debating whether to cancel testing again in 2021. One factor they should consider is whether a two-year gap in testing will make it impossible to measure student-level…

This dissertation is comprised of three essays, each examining a different topic in labor economics. In Chapter 1, I examine the productivity and selection effects of K-12 teacher tenure by leveraging variation from New Jersey's TEACHNJ Act. This law extended the pre-tenure period from three to four years and allowed districts to dismiss…

Value-added assessment is designed to measure teacher contributions to student achievement in order to promote effective teaching (Battelle for Kids, 2011b; Darling-Hammond et al., 2012; Lee, 2011). When value-added assessment is used, research indicates that in some cases effective teaching is promoted, but in other cases it is not…

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…

We used longitudinal data on high school students in Washington State to assess the relationships between English Language Arts (ELA) teacher qualifications and the high school and postsecondary outcomes of their students, and whether these relationships differed for students with and without disabilities. We found that students assigned to…

Since the emergence of middle schools as distinct educational settings in the 1960s, proponents of the model have advocated for structures and approaches that best meet the particular developmental needs of young adolescents. Middle school researchers have developed frameworks of best practices for schools that have been widely, if not uniformly,…

We examine access to effective teachers for low-income students in 26 geographically dispersed school districts over a 5-year period. We measure teacher effectiveness using a value-added model that accounts for measurement error in prior test scores and peer effects. Differences between the average value added of teachers of high- and low-income…

Using two states' grades 3 through 8 state assessment databases, this study documents the extent to which students were assigned testing accommodations for ELA or mathematics in only one of two consecutive years. The percentage of students with disabilities who were assigned accommodations in the current year only or in the prior year only in a…

We use longitudinal data on high school students in Washington State to assess the relationships between English Language Arts (ELA) teacher value added and other qualifications and the high school and postsecondary outcomes of their students. We also investigate whether these relationships differ for students with and without disabilities. We…

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…

Papay (2011) noticed that teacher value-added measures (VAMs) from a statistical model using the most common pre/post testing timeframe--current-year spring relative to previous spring (SS)--are essentially unrelated to those same teachers' VAMs when instead using next-fall relative to current-fall (FF). This is concerning since this choice--made…

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…

Measures of school-level growth in student outcomes are common tools used to assess the impacts of schools. The vast majority of these measures are based on standardized tests, even though emerging evidence demonstrates the importance of social-emotional skills (SEL). This paper uses the first large-scale panel surveys of students on SEL to…

This report provides an overview of the process used to derive a school's growth level and summarizes 2015 math and reading/ELA growth levels for all AISD elementary, middle and high schools. Additionally, longitudinal data are provided for each school level.
