The implementation and student outcomes of Tech Prep were examined in a study of eight consortia that represented a range of Tech Prep models and approaches in urban, suburban, and rural locations across the United States. Data were collected from the following sources: field visits; follow-up survey of Tech Prep participants and nonparticipants; nearly 2,000 student transcripts; more than 300 interviews with teachers, counselors, parents, and employers at 60 high schools and 10 community and four-year colleges; interviews with 150 secondary and postsecondary students; and follow-up study of 4,700 students from the 8 consortia. The following were among the study's main conclusions: (1) Tech Prep and School-To-Work (STW) have formed productive bonds in some local tech prep consortia; (2) enrollment increases of Tech Prep students as a portion of the total high school enrollment of 60-250% were found in all consortia; and (3) more than 70% of tech prep participants responding to the follow-up survey had enrolled in some form of postsecondary education (including a substantial number who had enrolled in four-year institutions).
