In the spring of 1966, a follow-up study of the original form of the ACT Student Profile Section (SPS) was conducted at 35 colleges. As a part of the larger study, this report investigates the question of how accurately the students' pre-college responses predicted their behavior and plans during the first year of college. The follow-up data were paired with original data for 5,617 students on such topics as vocational and educational plans and aspirations, choice of major, reasons for college attendance, expected need (if any) for financial help, estimated part-time work plans, housing needs, ownership or use of a car, expected extracurricular participation. The data suggest three generalizations: (1) the students tend to do what they say they will do, or something closely related to it, during their first year; (2) lack of follow-through may be caused by a change of mind by the student, a change of policy or opportunity presented by the college, or a change in the choice of college or goals; and (3) when appropriately evaluated, SPS data can help colleges plan for, as well as counsel, entering students. Answers, for example, to the pre-college questions on automobiles and housing plans could help the college estimate parking and dormitory requirements. (HH)
