In September 1992, a peer mentoring program was initiated at Santa Rosa Junior College (SRJC), in California, to address the disproportionately low enrollment and retention rates of minority and disabled students. This handbook is designed for colleges considering establishing similar mentoring programs and provides background information on SRJC's program and sample program materials. Following a brief preface, the objectives and outcomes for the first year of the program are described, identifying the main objectives as program development, trainee recruitment, mentor selection, the establishment of outreach programs, high school student recruitment, and increasing the visibility and recognition of underrepresented students at the college. This section also indicates that 40 underrepresented students were enrolled in the program, 30 completed the program, and 20 of these completers were selected to be peer mentors. Information is then provided on project management, the recruitment of peer mentors, the organization of the project advisory committee, the training of mentors through a campus guidance course, extracurricular concurrent activities for mentor trainees (i.e., cultural events, retreats, recognition ceremonies, etc.), the recruitment of student proteges, and the use of student peer mentors as a campus resource. Finally, initial efforts at evaluating the program are described and recommendations for colleges planning to develop a similar program are provided. Extensive appendixes provide sample brochures, forms, and articles related to each of the program's six objectives. (MAB)
