This six-part evaluative report describes and assesses three projects, funded by the Office of the Chancellor of the California Community Colleges, designed to facilitate the transition of low-income, minority, and handicapped students from two- to four-year colleges. Part One provides information on the legislative mandate and goals for the projects, evaluation procedures and limits, and the report. Part Two places the projects in the context of the transfer problems of underrepresented students and provides an overview of the characteristics of the three transition projects and the student participants. Parts Three through Five provide a detailed description of the three projects: (1) the Sacramento Student Transition Project, which recruited community college students throughout California to participate in work-experience internships in various state offices and to be enrolled at California State University, Sacramento; (2) the Merced-Modesto-San Joaquin Delta Student Transition Project, which provided transition services for students at three community colleges and concurrent enrollment at California State College, Stanislaus; and (3) the San Diego Student Transition Project, which offered individual transition counseling and orientation seminars at four-year colleges. Each description includes information on achievement of goals, project administration, intersegmental cooperation, and institutional commitment. Finally, Part Six offers summary observations and conclusions. Responses to the evaluation are appended. (AYC)
