The PT is an American national longitudinal study of about 377,000 individuals born in 1942–1946 and from 1200 schools across the United States of America. Participants were first assessed in 1960 while in secondary school (Grades 9–12). The study included a 5 percent random sample of all high school in United States of America—including public, private, and parochial schools—from every state except Alaska. Students from all economic, cultural, and social backgrounds participated in the base year data collection. PT researchers followed the students across early adulthood, surveying participants at 1, 5, and 11 years following their anticipated high school graduation.
