Building the STEM Talent Pipeline: The Impact of Project Lead the Way
Project Lead the Way (PLTW) is an applied STEM Career Technical Education program that has been adopted widely across the country. Using data from Missouri, we investigate the impact of PLTW course expansion on program participation and early post-secondary outcomes overall and by gender. Our… more →
Assessment Design and Course Grades: Evidence from Linked College Syllabi and Grade Records
Grade inflation is of increasing concern on college campuses, yet little is known about the course-level practices associated with higher grades. We examine one such practice: assessment design. Using syllabi from more than 400 undergraduate courses at four public universities, we identify… more →
Nowcasting Teacher Turnover
Policymakers need timely, local information about teacher turnover to make informed decisions, yet turnover data are typically several years out of date and lack the context to assess whether a district's turnover is high or low relative to similar districts. We assemble district-level teacher… more →
Human-, GRM-, and LLM-Generated School-Improvement Leadership Scores from Missouri: Structural Bias and Concurrent and Predictive Validity
Head or assistant principal evaluation systems are widely deployed but rarely examined for validity, and AI scoring tools have entered K–12 workflows ahead of the evidence. We examine human supervisor ratings, Graded Response Model (GRM) rescaling, and large language model (LLM) scoring of 1,385… more →
Staffing, Retention, and Expenditures in the Four-Day School Week
School districts across the United States are increasingly adopting the four-day school week, often in the hope of addressing teacher staffing challenges. We examine the effects of the four-day week on non-teacher staffing and recruitment, and schoolwide expenditures in Missouri, where three in… more →
The Effect of Air Pollution on Student Achievement: A Systematic Review and Meta-Analysis of the Causal Evidence
Air pollution is one of the most pressing global public health challenges of the 21st century. This article presents a systematic review and meta-analysis of the best available evidence of the effect of air pollution on student achievement. A meta-analysis of 28 causal studies around the world… more →
More Often or Longer? The Effects of the Academic Schedule on Postsecondary Academic Outcomes
One of the most common scheduling decisions in higher education is the determination of biweekly or triweekly classes. On the surface, these two formats are equivalent in terms of the number of minutes in a course (75 minutes twice a week or 50 minutes three times a week). However, the two… more →
The Early Intervention and Early Childhood Special Education Workforce: Descriptive Evidence on Demographics and Turnover from Oregon
Early intervention (EI) and early childhood special education (ECSE) services for children with disabilities have expanded substantially across the U.S. over the past few decades, necessitating efforts to recruit and retain a qualified workforce to meet their needs. Despite widespread reports of… more →
The Effects of K-12 Computer Science Education Policies on Postsecondary CS Participation
States have increasingly adopted policies to promote computer science education at the elementary and secondary levels. These policies are intended, in part, to promote the pursuit of computer science at the postsecondary level. We collect novel longitudinal data on adoption and implementation… more →
Exploring Claims of Critical Race Theory, Divisive Topics, and Indoctrination in the Classroom
Critical race theory (CRT) and claims of political indoctrination in K-12 classrooms are at the forefront of the ongoing culture wars surrounding public education. Despite a wave of legislative action targeting CRT-related instruction, little systematic evidence documents the extent to which… more →
Revisiting The Rural Teacher Workforce: Insights from a Novel Rurality Measure
How we define rurality fundamentally shapes our place-based understanding of the teacher workforce. This study uses the Community Assets and Relative Rurality (CARR) Index—a novel, multidimensional measure of rurality—alongside longitudinal administrative data to examine K–12 teachers in Kansas… more →
Searching for the Queen’s Gambit: An Exploratory Analysis of Male-Female Ratings Gaps in U.S. Chess
We examine the origin and evolution of male-female rating gaps for young chess players using two decades of data from the U.S. Chess Federation, the national chess association that tracks competitive tournament play and provides ratings for U.S. chess players. An important feature of our… more →
The Peer Effects of Grade Retention
We study the peer effects of grade retention in the context of Indiana’s statewide third-grade retention policy. When a retention occurs, it changes the peer group for two cohorts: rising fourth graders who lose a peer and rising third graders who gain a peer. We identify peer effects in both… more →
Leveraging Quarterly Workforce Indicators to Analyze Teacher Labor Market Dynamics: Inequitable Trends in Educator Turnover
Educator labor markets vary considerably across the country and can change quickly during recessions. We use data from the Quality Workforce Indicators (QWI) on educators in Elementary and Secondary Schools from 2000-01 to 2022-23. We demonstrate how to transform the quarter-level data in the… more →
The Decline in Teacher Working Conditions During and After the COVID Pandemic
We study changes to teacher working conditions from 2016-17 to 2022-23, covering school years before, during, and after the COVID pandemic. We show working conditions were improving leading into the pandemic but declined when the pandemic arrived. Perhaps more surprisingly, the peak of the… more →
Pinpointing Persistence in Alternative STEM Pipelines: Evidence from a Novel Coding and Apprenticeship Program
The shortage of STEM workers, particularly in computer science, is compounded by the underrepresentation of women and certain minoritized racial/ethnic groups in these fields. Efforts to address worker shortages and broaden participation include improving traditional STEM education pathways and… more →
Project Lead the Way: Impacts of a High School Applied STEM Program on Early Post-Secondary Outcomes
Project Lead the Way (PLTW) is an applied STEM program first introduced nearly three decades ago to enhance the STEM content of Career Technical Education (CTE). Currently, more than 12,000 US high schools offer the program. Using data from three cohorts of public high school freshmen in… more →
Technology Apprenticeships and Labor Market Outcomes: Mixed-Methods Evidence from the LaunchCode Program
We leverage employment and earnings data from a large credit bureau, program data from LaunchCode—a free technology education, and in-depth interviews with applicants and instructors to examine if the LaunchCode program leads to economic benefits, who is most likely to experience these benefits,… more →
Diversity Trends Among Faculty in STEM and non-STEM Fields at Selective Public Universities in the U.S. from 2016 to 2023
During the 2015-16 academic year, racial protests swept across college campuses in the U.S. These protests were followed by large university investments in initiatives to promote diversity, which combined with existing diversity dynamics, have helped to shape recent faculty diversity trends. We… more →
Less is More: The Causal Effect of Four-Day School Weeks on Employee Turnover
The use of four-day school weeks (4dsw) in the United States has expanded rapidly over the past two decades. Previous work examines the impact of 4dsw on student outcomes, but little research to date examines the effect on school employees even though schools in some locales have adopted 4dsw to… more →
