Research Findings: The present study investigated the role of ethnic similarity in the peer preferences and play quality of Latino and Chinese children enrolled in Head Start classrooms and the relationship between peer acceptance and social adjustment in these groups. Participants were 244 children (M = 4.6 years old) from Head Start preschools…

This report examines the academic impact of the COVID-19 pandemic on Black, Indigenous, and people of color (BIPOC) students, with the goal of documenting achievement trends to provide leaders and policymakers with evidence to guide action to address educational inequities for BIPOC students. Using math and reading test data from 2.1 million BIPOC…

Although the number of emergent bilinguals (EBs), also known as English language learners (ELLs) in U.S. K-12 schools is growing at an increasing rate, K-12 mainstream teachers remain predominantly white and monolingual and receive little training for working with such learners. In addition, many states mandate "English-only" policies…

I use standardized test scores from roughly 45 million students to describe the temporal structure of educational opportunity in over 11,000 school districts--almost every district in the US. For each school district, I construct two measures: the average academic performance of students in grade 3 and the within-cohort growth in test scores from…

California's Kindergarten Readiness Act of 2010 revised the cutoff date by which children must turn five for kindergarten entry in that year and established transitional kindergarten (TK), defined as the first year of a two-year kindergarten program for all students affected by the birthdate eligibility change. Since it has been implemented across…

Disparities in science achievement across race and gender have been well documented in secondary and postsecondary school; however, the science achievement gap in the early years of elementary school remains understudied. We present findings from the recently released Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 that…

About one in five Minnesota children under age 8 has a parent who speaks a language other than English at home. These Dual Language Learners (DLLs), who numbered 136,000 in 2011-15, come from a wide array of national, linguistic, and cultural backgrounds--a reflection of Minnesota's sizeable refugee communities from East Africa and Southeast Asia…

Assessing students at kindergarten entry allows teachers to effectively plan instruction that meets individual student needs, and those of the class as a whole. Maryland uses Ready for Kindergarten (R4K): Maryland's Comprehensive Early Childhood Assessment System, a single coordinated system for measuring the knowledge, skills, and behaviors and…

Minnesota has a persistent and substantial student achievement gap based on race and family income. There are also substantial achievement gaps between native English speakers and English learners (Minnesota Compass, n.d.). In 2019, Saint Paul Promise Neighborhood (SPPN) worked with Hmong American Partnership (HAP) and Saint Paul Public Schools…

Private and public investments in early childhood education have expanded significantly in recent years. Despite this heightened investment, we have little empirical evidence on whether children today enter school with different skills than they did in the late nineties. Using two large, nationally representative datasets, this paper documents how…

Maryland is charged with providing an equal education and ensuring that personal or social circumstances--such as immigration status, ethnic background, socioeconomic status, English proficiency, or disability--are not barriers to academic success. Equity is achieved when all students have the resources they need, such as exceptional teachers or…

In 2016-2017 the Department of Early Learning (DEL) is undertaking a new Racial Equity Initiative to strengthen the department's organizational capacity to advance racial equity. The outline for this initiative describes the need for "data and metrics to track results and measure the impact of DEL's actions at the child/family/community level…

As the foreign-born population in the United States grows, the achievement of immigrant children is a pressing concern. We examined family educational involvement in early elementary school as a potential source of support for the academic success of children in immigrant families. Using a nationally representative sample, we examined rates of…

Children's literature serves as mirrors and windows for the students we teach today. Through literature, children should be able to see their own reflections as well as the world around them. Yet despite their long history in the United States, Asian Americans have not always been represented in children's literature. This study analyzed the…

By the start of kindergarten, there are already large gaps in achievement between black and Hispanic children and their white peers, between children from lower socioeconomic backgrounds and their higher socioeconomic counterparts, and between dual language learners (DLLs) and their native English-speaking peers. This dissertation examines the…
