Decades of research on early care and education have shown that four-year-old children who enroll in prekindergarten (pre-K) programs start kindergarten scoring higher on assessments of academic skills than those who do not. A handful of long-term follow-up studies of pre-K have also found that these programs can have lasting beneficial impacts on…

There is clear evidence that the COVID-19 pandemic had significant negative effects on the learning and development of school-age children in the United States, with disproportionate impacts on children from racially, ethnically, and socioeconomically marginalized groups. There is less consistent evidence on the extent to which the pandemic…

Research shows that high-quality pre-K can have lasting impacts on children's learning and development, with the largest effects clustered among children of color, multilin­gual learners, and children experiencing poverty. Yet policymakers, administrators, and teachers often wrestle with the complexities of providing these programs on a large…

As the availability of high-quality, center-based prekindergarten (pre-K) has increased, so too has the attention given to children's learning experiences in the summer between pre-K and kindergarten. Investment in summer learning programs may help sustain the effects of pre-K and also boost the outcomes of children who don't enroll in a formal…

In this paper we use data from students who participated in the oversubscribed Boston Public Schools (BPS) prekindergarten program as a window into variation in the program's medium-term effects. We first examine whether, for the sample of students who applied to oversubscribed BPS prekindergarten programs, there is variation in the effects of the…

Growing investments in preschool at the federal and state levels--particularly in evidence-based approaches to language acquisition and reading--are predicated in part on the hope that high-quality preschools might help close the gap between the school achievement of low-income children and their more affluent peers. Indeed, the problem is…

Low-income preschool children face risks to their social-emotional development that can affect them later on. Although there are promising approaches to promoting preschoolers' social-emotional skills, the evidence base is limited, particularly on their effectiveness when implemented at scale. The Head Start CARES demonstration evaluated the…
