The Pre-Postsecondary Program (PPSP) was conducted during the 1974-75 school year at four Ohio secondary schools in order to offer a career exploration program for students in grades 11 and 12 that would be related to the high school content and provide a foundation for careers in the students' areas of interest. The report presents the evaluation of the PPSP in social science at Live Oaks Joint Vocational School and in health at Scarlet Oaks and Penta Joint vocational schools and Firestone High School. Program teachers and administrators discussed objectives for evaluation of the PPSP and developed criterion-referenced tests to assess students' achievement of the various programs' objectives. These tests were given to control groups and to PPSP students and the resulting scores analyzed and compared. Descriptions of all tests (interest, achievement, and ability) are presented for the different locations, programs, and test forms. It was found that the PPSP appears to have resulted in general achievement comparable to a traditional high school curriculum, in addition to giving some of the students specialized knowledge about their career areas. Most of the document is comprised of appendixes detailing the questionnaires, surveys, tests, and comments of administrators, teachers, parents, and students. (MF)
