In community college/high school 2 + 2 programs, a four-year program of technical training is begun in the last two years of high school and continued through two years of community college. In spite of a growing interest in such programs, current efforts have been limited to course articulation in which prerequisites for two-year college courses are taken in high school, rather than actual program articulation in which a sequence of courses are developed which can be undertaken by students beginning in high school. In 1989, a two-part study of community college/high school articulation was conducted in California. The first phase of the study sought to determine how 2 + 2 programs are defined and what their components are. This phase of the study brought together a panel of 10 vocational educators and administrators from the secondary and post-secondary levels and, using the Delphi consensus technique, examined opinions concerning the purpose, eligible participants, curriculum, credits, and time-frame for a 2 + 2 program. The second phase examined barriers to implementing such programs identified in surveys completed by 63 vocational instructional administrators. These barriers included the following: (1) difficulties in effectively informing parents and students of the existence and benefits of such programs; (2) the lack of funds to provide released time for planning and curriculum development; and (3) current state regulations that limit a community college to using credit by examination as the mechanism for granting college credit for articulated courses. In addition, it was found that perceptions of barriers were greater among the respondents less experienced with such programs. A list of eight recommendations emerging from the study, and the names of Delphi panel members and participating institutions are included. (JMC)
