This paper evaluates the long-run effects of Head Start using large-scale, restricted 2000-2018 Census-ACS data linked to the SSA's Numident file, which contains exact date and county of birth. Using the county rollout of Head Start between 1965 and 1980 and age-eligibility cutoffs for school...

This paper evaluates the long-run effects of Head Start using large-scale, restricted 2000-2018 Census-ACS data linked to the SSA’s Numident file, which contains exact date and county of birth. Using the county rollout of Head Start between 1965 and 1980 and age-eligibility cutoffs for school...

This report presents evidence of the short- and medium-term impacts of the programme on educational outcomes. Using a robust evaluation methodology and administrative education data covering 15 cohorts of children, we measure the impact of having had access to a Sure Start centre between ages 0...

We offer a new analysis of a large-scale trial of an early-childhood education program that targeted premature, low-birthweight children. This targeting heavily oversampled twins, whose outcomes differed significantly from singletons'. Singletons' gains in short-term cognition and age-18...

How much of the income-based gaps in cognitive ability and academic achievement could be closed by a two-year, center-based early childhood education intervention? Data from the Infant Health and Development Program (IHDP), which randomly assigned treatment to low birth weight children from both...
