The college careers of students who had participated in the Advanced Placement Program (AP) in secondary school were studied, based on extensive information on 4,814 students who participated in the Personal Qualities Project, a longitudinal study in nine colleges and universities. The project included information on 1,115 AP and 3,699 non-AP students. The two groups were contrasted on a number of measures: background characteristics, special achievements in secondary school, goals and interests, experience in college, and different measures of success. Various subgroups of AP students were also compared. Areas of study included: how AP and non-AP students compare at the time of college entry; whether AP and non-AP students take a similar academic program on a similar schedule; how AP students perform academically through 4 years; whether there are differences between AP and non-AP students generally comparable for major groups of students; whether advanced placement in particular subjects reduces the likelihood of students taking college coursework in those areas; and whether the AP grade is a useful predictor of college performance. The Personal Qualities in Admissions Research Questionnaire is appended. (SW)
