Three tech prep teachers and one counselor at a Vermont high school examined tech prep's effectiveness in influencing students' career decisions and their intentions to receive postsecondary education. Three methods were used to collect data at the end of the third 9-week quarter of the school year: analyzing students' course selections, grades, and responses to a 10-item survey. The teacher researchers found that 14 of the 22 students enrolled in the school's Tech Prep Potential class signed up to take additional college prep courses, and 6 opted to attend a career center. Compared with other students at the high school, the Tech Prep Potential students' grade point average for science, mathematics, and English during their sophomore years averaged 0.62 points lower. This difference was attributed to the fact that meeting the standards needed to participate in the Tech Prep Potential program requires students to schedule more challenging courses than they might choose otherwise. According to the student survey, the Tech Prep Potential was most beneficial in exposing students to new careers. It was also considered valuable in explaining the importance of postsecondary education. (A four-item annotated bibliography is included. Appended is the tech prep student survey.) (MN)
