This practicum paper describes the design and implementation of a mentoring program to improve the academic achievement of black male urban high school students. The program utilizes black adult mentors from both the community and the school's faculty. Mentors function as role models, advisers, and resource persons. The program design includes the following components: (1) a school-based committee responsible for program implementation and for identifying student participants; (2) training for mentors; (3) periodic progress reports prepared by mentors; (4) after-school tutoring; (5) small group counseling; (6) career planning; and (7) program evaluation based on improvement in student test scores. Most of the program was funded from the regular school budget, with supplementary funds provided by the Parent Teachers Association. The program did not meet its overall goals for improving student test scores by one full point, perhaps because the target was unrealistic. However, participants did show improvement in attendance, test results, and postgraduation planning. The following materials are appended: (1) a list of 18 references; (2) 6 tables of statistical data; (3) a student progress report form; and (4) a mentor handbook developed by the school committee.
