HighScope Perry Preschool

By age 40, adults who participated as 3- and 4-year-olds in quality preschool were more likely to have graduated from highschool, held a job, made higher earnings, and committed fewer crimes than those who didn’t attend, according to this seminal study. In 1962, researchers began following 123 high-risk 3- and 4-year-olds and their families in Ypsilanti, Michigan. nearly 60 of those children were randomly assigned to a high-quality early learning program; the rest received no preschool.
