A study undertaken in Arizona in 1975 was comprised of two parts, a pilot study and a comprehensive survey of high school students. It had as an overall objective to provide a data resource useful to all citizens and postsecondary institutions, to manpower and employment agencies, and to the state's high schools for program planning and counseling. A large sample of students was used, and a large number of usable responses resulted (over 6,000). The research design used viewed transition from high school to post-high school activities as existing in three distinguishable and mutually exclusive flows: (1) a work group; (2) a vocational-technical education group; and (3) a college group. In the final report considerable attention is given to the details of the study, as well as to its statistical results. An extensive bibliography is included. (MSE)
