Although research indicates that individual students benefit when they enroll in early algebra classes, evaluations of broad-based algebra acceleration often report negative effects. Using a regression discontinuity design, we replicate the positive effects of eighth-grade algebra placement on student achievement found in prior studies. We then…

Under the Every Student Succeeds Act, college and career readiness became the central focus of education policy in the United States. Career academies (CAs) are a popular way to support students in their postsecondary transitions, but little causal evidence exists about whether this model of schooling is effective in promoting learning and…

The success of students with disabilities (SWDs) depends on access to high-quality general education teachers. Yet, teacher value-added measures (VAMs) generally fail to distinguish between effectiveness in educating students with or without disabilities. Using data from the Los Angeles Unified School District, we create two VAMs: one focusing on…

Many educational policies hinge on the valid measurement of student economic disadvantage at the school level. Measures based on free and reduced-price lunch enrollment are used widely. However, recent research raises questions about their reliability, particularly following the introduction of universal free lunch in certain schools and…

We develop a conceptual framework for understanding and predicting teacher shortages at the state, region, district, and school levels. We then empirically examine how teacher shortages vary geographically and by subject using data on unfilled teaching positions in Tennessee traditional public schools during Fall 2019. We find that teacher…

In this article, we explore whether the evaluation instruments used in the teacher selection process in Peru are good predictors of teacher effectiveness. To this end, we estimate teacher value-added (TVA) measures for public primary school teachers and test their relationship with Peru's results of two rounds of the teacher evaluation (i.e., a…

The recent Every Student Succeeds Act (ESSA) requires states to identify and turn around their lowest performing schools, but it breaks somewhat from prior policies by granting states significant autonomy over how they identify and turn around these schools. This mixed-methods study, which draws on administrative, qualitative, and survey data,…

Valid and reliable measurements of teaching quality facilitate school-level decision-making and policies pertaining to teachers. Using nearly 1,000 word-to-word transcriptions of fourth- and fifth-grade English language arts classes, we apply novel text-as-data methods to develop automated measures of teaching to complement classroom observations…

This study examines the relationship between two dominant measures of teacher quality, teacher qualification and teacher effectiveness (measured by value-added modeling), in terms of their influence on students' short-term academic growth and long-term educational success (measured by bachelor's degree attainment). As students are exposed to…

Nationally, 18% of principals turn over each year, yet research has not yet credibly established the effects of this turnover on student and teacher outcomes. Using statewide data from Missouri and Tennessee, we employ a difference-in-differences model with a matched comparison group to estimate arguably causal effects. We find that principal…

A key question facing teacher evaluation systems is how to combine multiple measures of complex constructs into composite indicators of performance. We use data from the Measures of Effective Teaching (MET) study to investigate the measurement properties of composite indicators obtained under various conjunctive, disjunctive (or complementary),…

We investigated teacher effects (magnitude, predictors, and cumulativeness) on primary students' achievement trajectories in Chile, using multilevel cross-classified (accelerated) growth models (four overlapping cohorts, spanning Grades 3 to 8; n = 19,704 students, and 851 language and 812 mathematics teachers, in 156 schools). It was found that…

Many schools and districts have considerable discretion when hiring teachers, yet little is known about how that discretion should be used. Using data from a new teacher screening system in the Los Angeles Unified School District (LAUSD), we find that performance during screening, and especially performance on specific screening assessments, is…

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…

Teachers' on-the-job interactions with colleagues impact their effectiveness, yet little research has explored whether and how teacher performance predicts these interactions. Drawing on 5 years of social network data from one school district, we explore the relationship between teacher performance and teachers' instructional advice and…
