Changes in Kindergarten Redshirting During the COVID-19 Pandemic
This study examined the impact of COVID-19 on academic "redshirting" in kindergarten, the practice of holding a child back for a year and enrolling them in kindergarten at age 6, using student-level data on all Delaware kindergarten students from fall 2014 through fall 2022. The rate of… more →
The Effects of Public Pre-K for 3-year-olds on Early Elementary School Outcomes: Evidence from the DC Centralized Lottery
This study examines the effects of universal public pre-kindergarten for 3-year-olds (Pre-K3) on later public education outcomes, including enrollment, school mobility, special education status, and in-grade retention from kindergarten through second grade. While universal pre-kindergarten… more →
The Causal Effect of Parenting Style on Early Child Development
This paper presents causal evidence on the impact of parenting practices on early child development. We exploit exogenous changes in nurturing care induced by a parent training intervention to estimate the impact of nurturing parenting practices on child outcomes. We find a large and significant… more →
Is Authorized Capacity a Good Measure of Child Care Providers’ Current Capacity? New evidence from Virginia
Demand for child care in the United States outpaces supply. Understanding access issues is critical for addressing them and supporting children, families, and the economy. However, the most widely available proxy for child care supply—authorized capacity—likely overestimates care availability.… more →
The Challenges of Scaling up Effective Child-Rearing Practices Using Technology in Developing Settings: Experimental Evidence From India
Home-visitation programs have improved child development in low- and middle-income countries, but they are costly to scale due to their reliance on trained workers. We evaluated an inexpensive and low-tech alternative with 2,433 caregivers of children aged 6 to 30 months served by 250 public… more →
Exploring Multidimensional Approaches to Learning During Early Childhood in Ghana
Children's approaches to learning (AtL) are widely recognized as a critical predictor of educational outcomes, especially in early childhood. Nevertheless, there remains a dearth of understanding regarding the dimensionality of AtL, the reciprocal dynamics between AtL and learning outcomes, and… more →
Transitional Kindergarten: The New Kid on the Early Learning Block
In recent years, several states have expanded a new publicly funded learning option: Transitional Kindergarten (TK). TK programs bridge prekindergarten and kindergarten in their eligibility, requirements, and design. We use Michigan’s TK program as a case study on the fit of this new entrant in… more →
The Effect of Early Childhood Programs on Third-Grade Test Scores: Evidence from Transitional Kindergarten in Michigan
Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan’s TK program on 3rd grade test scores. Using an augmented regression… more →
The Ups and Downs of Classroom Quality Over the Preschool Year and Relations to Children’s School Readiness
Despite considerable evidence on the links between average classroom quality and children’s learning, the importance of variation in quality is not well understood. We examined whether three measures of variation in observed classroom quality over the school year – overall variation in quality,… more →
A Scalable Approach to High-Impact Tutoring for Young Readers: Results of a Randomized Controlled Trial
This paper presents the results from a randomized controlled trial of Chapter One, an early elementary reading tutoring program that embeds part-time tutors into the classroom to provide short bursts of 1:1 instruction. Eligible kindergarten students were randomly assigned to receive… more →
Are Preschool Programs Becoming Less Effective?
High-quality preschool programs are heralded as an effective policy tool to promote the development and life-long wellbeing of children from low-income families. Yet evaluations of recent preschool programs produce puzzling findings, including negative impacts, and divergent, weaker results than… more →
Assessing the Benefits of Education in Early Childhood: Evidence from a Pre-K Lottery in Georgia
Numerous studies have demonstrated a strong link between participation in pre-K programs and both short-term student achievement and positive later-life outcomes. Existing evidence primarily stems from experimental studies of small-scale, high-quality programs conducted in the 1960s and… more →
Rural Early Childhood Programs & School Readiness: An Evaluation of the Early Steps to School Success Program
Prior research has clearly established the substantial expected payoffs to investments in early childhood education. However, the ability to deliver early childhood programs differs across communities with access to high quality programing especially hard to establish in rural communities. We… more →
Instructional Alignment is Associated with Sustained Benefits of PreK
This study uses implementation fidelity data from PreK to 1st grade in the Boston Public Schools (BPS) to measure instructional alignment and examine whether stronger alignment is associated with sustained benefits of BPS PreK on children’s language, literacy, and math skills through first grade… more →
Comparing the School Readiness Skills of Public Pre-Kindergarten and Head Start Participants: A Systematic Review and Meta-Analysis
A systematic review of the literature (1965–2022) and meta-analysis were undertaken to compare the school readiness skills of children participating in public pre-kindergarten (pre-K) or Head Start. Seven quasi-experimental studies met the inclusion criteria for the meta-analysis and 38 effect… more →
Going the Distance: Exploring Variation in Access to High-Quality PreK by Geographic Proximity, Race/Ethnicity, Family Income, and Home Language
This study leverages six years of public prekindergarten (PreK) and kindergarten data (N = 22,469) from the Boston Public Schools (BPS) to examine enrollment in BPS PreK from 2012–2017 for students from different racial/ethnic, socioeconomic, and linguistic groups. The largest differences in… more →
Lottery-Based Evaluations of Early Education Programs: Opportunities and Challenges for Building the Next Generation of Evidence
Lottery-based identification strategies offer potential for generating the next generation of evidence on U.S.
Stay-at-Home Peer Mothers and Gender Norms: Short-run Effects on Educational Outcomes
Increased exposure to gender-role information affects a girl's educational performance. Utilizing the classroom randomization in Chinese middle schools, we find that the increased presence of stay-at-home peer mothers significantly reduces a girl's performance in mathematics. This exposure also… more →
Mixed-Delivery Public Prekindergarten: Differences in Demographics, Quality, and Children’s Gains in Community-Based versus Public School Programs across Five Large-Scale Systems
Nearly all states with public prekindergarten programs use mixed-delivery systems, with classrooms in both public schools and community-based settings. However, experts have long raised concerns about systematic inequities by setting within these public systems. We used data from… more →
Putting the K in Rank: How Kindergarten Classrooms Impact Short and Long-Run Outcomes
A student's class rank has important short and long-term effects on important educational outcomes. Despite our growing understanding of these rank effects, we still do not know how early in a child's academic career they begin. To address this, I use data from the Tennessee STAR project, which… more →
