Twenty-one California career-vocational educational articulation projects, commonly referred to as 2 + 2 partnerships, were jointly funded across the 1986-89 funding period and third-party evaluations were conducted in 1988-89. The longitudinal study examined the long-term effects of the original partnerships. Evaluators formed an advisory committee, reviewed project documentation, collected baseline data from 2,955 secondary students, and conducted site visits. During 1990-91, 15 partnerships continued or expanded project activities beyond the close of special federal funding. Most of the students were male. Nearly one-third of the students were Hispanic. The mean grade point average was 2.90. More than three-quarters of the students plan to earn a high school diploma and most intend to enroll in a community college. Several recommendations are offered based on the first year of the longitudinal study: (1) consider expansion of statewide support; (2) disseminate information regarding articulated credit; (3) consider the standardization of articulation forms; (4) emphasize the importance of counseling; (5) clarify the distinctions between 2 + 2 and tech prep; (6) develop a statewide management information system; and (7) expand the focus of the longitudinal study. (Seven figures, nine tables, and three appendices are included. The appendices contain a list of advisory committee members, student data forms, and program data forms/site visit interview schedules.) (NLA)
