Impact of States' Adoption of Response to Intervention (RTI) on Disability Identification
The rise of specific learning disability (SLD) identification from 1975 to the early 2000s prompted the 2004 reauthorization of the Individuals with Disabilities Education Act to permit states to use a student's response to intervention (RTI) in eligibility determination to improve… more →
Persisting Income-Based Preschool Enrollment Gap in the U.S., 2000 to 2023
This study aims to understand whether access to early childhood education (ECE) has become more equitable over a period of substantial growth in public pre-K investment. This study describes and statistically tests the differential trends across income groups in center-based ECE enrollment among… more →
Post-pandemic achievement recovery based on student characteristics and district-level policies
It is well-established that student achievement has declined dramatically since the onset of the COVID-19 pandemic. However, less is known how these patterns may vary by developmental timing of exposure to the pandemic and how district-level policies may have influenced student recovery.
Shine a Light: The U.S. Federal Government Should Increase Access to Educational Administrative Data
The Institute of Educational Sciences invested substantial resources into the Statewide Longitudinal Data Systems grant program. These grants helped states convert their educational records to longitudinal datasets for research and evaluation. However, external researchers still have unreliable… more →
Does Fadeout Preclude Long-Run Adult Effects? A Systematic Review and Meta-Analysis of Educational Intervention Randomized Controlled Trials
A perplexing pattern has been observed in the intervention literature: although impacts on children’s skills often fade, some interventions still produce long-run impacts on adult outcomes. Existing developmental theory does not provide a straightforward explanation. This “fadeoutemergence… more →
The Access–Enrollment Disconnect in Corequisite Math Reform: Causal Evidence and Stakeholder Perspectives from a Community College
This study examines a statewide developmental education reform in Virginia that allows students who would have been placed in standalone remedial math to enroll directly in college-level math with corequisite support. Although corequisite support has been widely adopted and generally promising,… more →
Using experimental variation to examine the (co-)development of cognitive and social-emotional skills in early childhood
How cognitive and social-emotional skills emerges in childhood is a central question in developmental psychology. Despite a proliferation of theory and empirical work, the field has struggled to establish causal effects. We employed a novel approach to test the stability and codevelopment of… more →
Evaluation Scores and Student Learning under Compulsory Teacher Re-Evaluation
We examine how lower-performing public school teachers respond to more frequent formative evaluations. A 2011 reform in Chile required teachers rated "basic" (the second-lowest category) to be re-evaluated after two years rather than four. Using nationwide administrative data on primary school… more →
Distinguishing Burdens from Benefits in Early Care and Education Policy
Contemporary policy conversations discuss burdens imposed by regulations, describing when they render government functions ineffective and inefficient. But one can mislabel the core purposes and benefits of a policy’s existence as burdens. Applying the administrative burden framework to early… more →
Ethnic Studies Courses Across California High Schools: A Mixed-Method Analysis of Teacher-Intended Curricula
Ethnic Studies courses, which center the counternarratives of racialized communities, are rapidly expanding across California in advance of a high school graduation requirement for the class of 2029-30. However, content and pedagogical guidance for practitioners remains limited. To learn how… more →
A Systematic Review of Research Designs Used to Evaluate State and Locally Funded Pre-K Programs
Expansions of state and locally funded pre-k programs in recent decades have been promoted by advocates citing strong research support. However, questions have been raised about how supportive the research base actually is. We conducted a systematic review of pre-k evaluation studies (from 2000… more →
Head Start Plus: The Case for Piloting a Cadillac Public ECE Program
The long-term impacts of early childhood education (ECE) programs at scale are smaller than those produced by influential demonstration programs half a century ago. Several factors likely contribute, some of which are in the control of policymakers and the designers of ECE programs (e.g.,… more →
23 Years of State Pre-K Expansion: How States Balance Investment, Access, and Quality in the Modern Era
We describe state-funded pre-kindergarten (pre-K) expansion in the modern era from 2002 to 2024, documenting patterns of investment and reach. Although spending and enrollment increased substantially, states pursued widely varying expansion strategies. A 200% increase in pre-K enrollment did not… more →
Discipline Beyond Suspensions: Racial/Ethnic Disparities Across the Spectrum of Disciplinary Actions
Little research examines whether the alternatives to suspension reduce racial/ethnic discipline disparities. Using unusually rich administrative data from a large district in the South, we investigate how schools use a range of disciplinary actions and the racial/ethnic gaps in their use. School… more →
The Maternal Labor Market Effects of State Pre-K Funding
Public pre-kindergarten (pre-K) is primarily designed as an educational policy for young children but has attracted attention as a potential lever to support maternal employment. This study provides national evidence on the maternal labor market effects of state pre-K funding, exploiting… more →
Teacher-student relationships and adult outcomes: Developmental cascades via childhood executive function and behavioral dysregulation
Longitudinal data were examined to test associations between teacher-student relationships and adult outcomes, as well as mechanisms underlying these associations. Results from the NICHD-SECCYD (N=1364; 52% male; 76% White; 13% Black; 6% Hispanic; 5% other; data collection took place in the U.S.… more →
Cultural Relevance at Scale: The Effects of an Ethnic Studies Expansion on Academic Outcomes
Ethnic Studies is a culturally relevant curriculum designed to address the instructional needs of an increasingly diverse student population. However, evidence regarding its effectiveness at scale remains limited. This study evaluates the impact of district-wide implementation using a student… more →
Gifted Identification Across the Distribution of Family Income
Currently, 6.1 percent of K-12 students in the United States receive gifted education. Using education and IRS data that provide information on students and their family income, we show pronounced differences in who schools identify as gifted across the distribution of family income. Under 4… more →
School-Based Disability Identification Varies by Student Family Income
Currently, 18 percent of K-12 students in the United States receive additional supports through the identification of a disability. Socioeconomic status is viewed as central to understanding who gets identified as having a disability, yet limited large-scale evidence examines how disability… more →
Predicting Persistence and Fadeout Across Multi-Site RCTs of an Early Childhood Mathematics Curriculum Intervention
This study examined predictors of persistence and fadeout across multiple cluster RCTs that evaluated a preschool mathematics curriculum. We used meta-analytic methods to explore how impacts on student mathematics achievement faded between post-test (i.e., endline) and one-year follow-up. We… more →
