This discussion of the transfer function of California's community colleges focuses on the problems of obtaining reliable information, research findings on factors affecting transfer success, and ways of accurately assessing transfer rates. After affirming the importance of the transfer function of community colleges, the paper examines flaws and inconsistencies in the data on student transfers and estimates that 5% of the students who enter community colleges complete a two-year program, transfer to a four-year institution and earn a baccalaureate degree, with an additional 7% to 8% transferring prior to completing a two-year program. The argument is presented that cooperative arrangements among all segments of postsecondary education in California will be required to obtain reliable information about transfer, and incipient efforts in California and more developed programs in other states are highlighted. Next, allegations that community college enrollment adversely affects students' chances of obtaining baccalaureate degrees are counterposed with evidence of the colleges' success in helping students achieve their goals. Research findings are then presented, focusing on articulation of curricula and transfer information, course numbering systems, the paucity of second-year courses, and activities that enhance transfer. Finally, it is suggested that a common entry form be used by all postsecondary institutions in California and that studies of baccalaureate degree recipients be conducted. (AYC)
