An evaluation was conducted to describe Tech Prep prototypes as they have been implemented in five sites in Indiana and to determine the effectiveness of the programs. Tech Prep is a curriculum initiative that: is performance based, provides students with skills necessary to gain employment or to pursue further education upon high school graduation, relates to a broad scope of occupations, includes academic skills taught through practical application, and allows for credit in high school and college and cooperative arrangements. Information was collected through site visits; document review; review of course materials; interviews with students, teachers, counselors, and administrators; and classroom observation. Results of the survey provided a description of the Tech Prep program as implemented at the five sites. The study concluded that each pilot program is well managed and staffed by enthusiastic teachers. It also found that all sites have done a good job of planning, developing, and implementing the pilot activities. No one curriculum model emerged as best; each had strengths and weaknesses and focused on specific needs of the communities and students in its area. Tech Prep has not been labeled a science, mathematics, or vocational program in any of the sites--this is viewed as a positive result that will facilitate dissemination. Recommendations were made for improving and expanding the Tech Prep program. (Appendix includes questionnaires.) (KC)
