HighScope Perry Preschool Study.
Sponsored by the National Institute on Aging (NIA) of the National Institutes of Health (NIH), the HighScope Perry Preschool Study (HPPS) is designed to teach us about the lasting effects of early childhood interventions, such as preschool programs. The original Perry Preschool Program targeted a disadvantaged African American population in the 1960s. Evaluated initially by a clinical trial of preschool age children, participants were then followed periodically through age 40. Results from this longitudinal survey show strong evidence for the benefits of children in the treatment group in the areas of improved school readiness, higher female graduation rates, higher employment rates and earnings, reduced involvement in crime, and high economic return on investment.
