The effects of participation in school-to-career (STC) on subsequent educational and career opportunities were examined in a longitudinal study of 1999 and 2000 graduates of the Lansing Area Manufacturing Partnership (LAMP), which is an STC program sponsored by the United Auto Workers, General Motors Corporation, and Michigan's Ingham County Intermediate School District. Mail surveys and telephone interviews were administered to 208 students (104 in the STC sample and 104 in the non-STC sample). A total of 195 students (101 STC-sample members and 94 non-STC sample members) completed the first-round and follow-up interviews, resulting in a response rate of 93.8%. Participation in the LAMP STC did not appear to limit the respondents' career or educational aspirations. Two-year colleges were the destination of choice for most graduates from both groups, and similar proportions of both groups were enrolled in four-year colleges. The STC participants were nearly four times as likely as the nonparticipants to have career goals relating to the automotive industry, although most graduates from both samples aspired to become professionals. Only 13% of the STC sample members were employed at the sponsoring company after graduation. Regardless of whether the STC graduates pursued further education or entered the world of work, they considered the STC program beneficial in making their postgraduation transitions and decisions.
