Explores the following five dimensions of self-perception held by black urban male 10th-grade students in North Carolina: (1) scholastic competence; (2) athletic competence; (3) physical appearance; (4) behavioral conduct; and (5) job competence. Investigates differences in these aspects of self-concept for 30 students scoring above and 30 scoring below the fiftieth percentile on the California Achievement Test (CAT). Subjects were administered the Self-Perception Profile for Adolescents. Higher achievers possess a perception of greater academic competence, and they perceive themselves as more competent at athletics and better looking than do the lower achieving group. Achievers also perceive themselves as more capable at a part-time job, and they feel better about the way they behave. Students who did well on the CAT place a high value on academic achievement and perceive that they have the potential to do well. Included are five tables of study findings and a 14-item list of references. (SLD)
