The Seattle (Washington) Tech Prep Demonstration Project involves the following consortium partners: North Seattle, Seattle Central, and South Seattle community colleges; 13 secondary schools of the Seattle School District; 8 businesses; an industrial association; and a labor union. The demonstration project was subjected to a comprehensive evaluation using the following methodologies: surveys of 1,897 tech prep students, interviews with key individuals, content and context analyses, focus group with tech prep students from two schools, observation of applied academic and professional technical education classes, and conduct of a local inventory. It was discovered that the tech prep program draws significantly larger percentages of minority students and students with lower grade point averages into community colleges. Because tech prep program graduates enrolled at four-year colleges at the same rate as non-tech prep graduates, the tech prep program was also concluded to be a good option for higher ability students. The evaluation team issued recommendations calling for the following: development of a clear vision of tech prep and its future; more intensive work to increase student, staff, parent, and employer awareness of tech prep; and improvement of methods to identify, monitor, and assess tech prep students' experiences and outcomes.
