“Perry Preschool Project: A longitudinal study that examined the lives of 123 African American children born in poverty and at high risk of school failure. From 1962 to 1967, at ages 3 and 4, the subjects were randomly divided into a program group that received a high-quality preschool program and a comparison group that received no preschool program. Those who participated in the high-quality preschool program were later found to have higher earnings, to be more likely to be employed, to be less likely to have committed crimes, and to be more likely to have graduated from high school than were adults from the comparison group who had received no preschool education.”
