When Advanced Learning Programs Expand: Evidence on Access and Achievement
This paper examines how a district-wide expansion of an advanced learning program reshaped access and short-run academic outcomes. The reform replaced an opt-in identification process with universal screening based on district assessments and expanded program capacity, resulting in larger… more →
Empty Desks: Schools and Staffing after the Pandemic
Sustained enrollment losses and other post-pandemic factors have placed budgetary pressures on many school districts and motivated difficult discussions about both closing under enrolled schools and staffing reductions. Using the most currently available national data, this brief provides… more →
Interpreting Null Effects in Education: Insights from a Tutoring Experiment
We learn not only from when interventions work—but also from why they do not. Policymakers embraced high impact tutoring to address pandemic learning loss, but scaling promising practices is difficult, and not all implementations prove effective. Using random assignment, we find null (math and a… more →
Big P and Little P Politics: Contemporary and Enduring Challenges for K-12 School Board Members
School board service has become more complex in the current era of heightened partisan polarization and the nationalization of education. This mixed-methods paper draws on interviews with and a statewide survey of board members in California, and the theory of emotional labor. We explore how… more →
Facilitating Evidence-Based Instructional Coaching With Automated Feedback on Teacher Discourse
Instructional coaching often aims to ground teacher professional learning in classroom evidence, yet it is labor-intensive for coaches to obtain and curate such evidence. This study explores possibilities for applying an automated feedback tool to classroom recordings in order to support… more →
Tutor Traits and Student Achievement: Evidence from a Randomized Experiment
Tutors are increasingly central to school-based instruction, with the potential to personalize learning at scale. Little is known about which tutor characteristics predict effectiveness, limiting providers' and schools' recruiting, hiring, and retention strategies. Using random assignment of… more →
When Youth Enter The Chat: An Epistemic Shift in the Validation of LLM-Based Measures of Student Talk
Large Language Models (LLMs) are being used increasingly to measure aspects of student discourse (e.g. talk moves, collaboration, equity of voice) at scale. Typically, LLM-based measures of student talk use transcriptions of classroom conversations that only include verbal contributions, which… more →
Estimating the Overall Effects of Statewide Early Literacy Policies: Evidence from Michigan
This paper evaluates the impacts of Michigan's statewide early literacy reform using a synthetic difference-in-differences approach. We estimate the policy’s effects on student achievement and grade retention and compare them to statewide literacy reforms in South Carolina and Mississippi. We… more →
Early literacy tutoring and children’s reading trajectories: Evidence from a four-year randomized controlled trial
Most evidence on early literacy tutoring comes from intensive one-year interventions. Much less is known about whether schools can sustain individualized instructional support as students’ reading needs evolve across the early grades. We present findings from a four-year randomized controlled… more →
Unpacking Treatment Effect Heterogeneity in a Large-Scale Dropout-Prevention Experiment
Timely high school completion is a critical step in successful transitions to post-secondary schooling and the labor market. This randomized controlled trial, deployed in two urban, disadvantaged school districts, tests the effectiveness of a mature and comprehensive student-support program on… more →
Tracking to Retain Higher-Income Students: Evidence from the Addition of Advanced Courses
Public schools may introduce academic tracks to attract or retain higher-income students. The role of intra-school policies in shaping higher-income families’ demand for public schools has been underexplored. Using variation in the timing of advanced course introductions in Texas high schools, I… more →
Access is Not Enough: Human Support Improves Engagement with AI Tutoring
AI tutoring platforms offer a promising path to scaling personalized instruction, but only if students use them. We report findings from two randomized controlled trials in which elementary students were assigned to use an AI literacy platform independently or with an in-person tutor focused on… more →
The Effects of High-Impact Tutoring on Student Attendance: Evidence from a State Initiative
Student absenteeism surged during and after the pandemic, harming engagement and achievement. We evaluate the impact of Washington DC’s High-Impact Tutoring (HIT) Initiative—designed to mitigate learning loss through targeted academic supports—on student absenteeism. Using daily attendance data… more →
The Challenge of Capturing Higher-Order Thinking Skills at Scale
Higher-order thinking skills are important for K-12 students’ long-term success. However, the lack of widely administered assessments designed to capture this construct has made it difficult to measure higher-order skills at scale. This paper examines the measurement properties of an approach to… more →
Answering the call: How changes to the salience of job characteristics affect college students’ decisions
College students often make employment decisions with incomplete information, particularly about compensation. As a result, they may rely on misleading heuristics (such as assuming that interesting or prosocial jobs pay badly) and overlook campus positions that would support both their financial… more →
Public Opinion on Electoral Policy: Evidence from U.S. School Board Elections
Changes to electoral systems are relatively rare in established democracies. Conventional explanations for this stability suggest elected officials and citizens who stand to lose influence under new arrangements will oppose change. We explore the nature of public awareness and opinion regarding… more →
Practitioner Voices Summit: How Teachers Evaluate AI Tools through Deliberative Sensemaking
Teachers face growing pressure to integrate AI tools into their classrooms, yet are rarely positioned as agentic decision-makers in this process. Understanding the criteria teachers use to evaluate AI tools, and the conditions that support such reasoning, is essential for responsible AI… more →
The Static Nature of the Childcare Workforce, 1990 to 2025
Despite decades of policy attention aimed at strengthening the early childhood care and education workforce, concerns about low pay, high turnover, and limited economic security persist. This paper revisits whether the composition and economic conditions of the childcare workforce have… more →
A Sandbox for Hard Choices: Using Simulation to Explore School Closure Scenarios and Their Consequences
School closures are often justified through seemingly neutral criteria such as enrollment or performance, but these metrics can unintentionally deepen educational disparities. This study uses a large urban district’s administrative data to simulate 5,040 closure scenarios, systematically varying… more →
The Expansion of Alternative Schools: Impact of Schools Targeting Lower Performing Students
Despite rising high school graduation rates in the US, a substantial portion of students do not obtain a high school degree. Alternative schools have emerged as a potential solution offering opportunities for credit recovery and flexible scheduling. Using variation in the timing and proximity of… more →
