A research study explored the barriers to transfer of credit courses from two-year community and technical colleges to four-year colleges and universities, with special attention to the concerns of postsecondary occupational-technical program transfer. Several categories of problems were identified in the national literature on higher education transfer: attitudinal, institutional, geographical, financial, curricular, and structural barriers. Key issues and arguments in each category were explored and discussed. The research concluded that transfer of credits was more successful when community colleges separated two-year transfer programs and vocational-technical programs. A suggestion was also made that comprehensive community colleges with four-year programs might be better able to serve the needs of the diverse types of students who enroll in community colleges. (KC)
