A study was done of 5 selected domains of self-perception held by 60 urban black male 10th graders in North Carolina. The domains were scholastic competence, athletic competence, physical appearance, behavioral conduct, and job competence. Each domain was transformed into a research questions. Achievers (n=30) and potential achievers (n=30) as measured by the California Achievement Test (CAT) were compared on each question. Achievers had scored above the 50th percentile on the CAT and the potential achievers had scored below the 50th percentile. The research design was causal-comparative, with the independent variable being achievement. The findings reveal statistically significant differences for scholastic competence, job competence, and behavioral competence. The mean scores of the achievers on these three domains were greater than those of the potential achievers. Surprisingly, there were statistically significant differences on athletic competence and physical appearance, with the potential achievers having the greatest mean scores. The potential achievers' perceptions of athletic ability and competence at sports were greater than the achievers'. They perceived themselves to be very good at sports and athletic activities and to be more "good-looking." The potential achievers were certain of a successful career as an athlete or entertainer. Classroom instructional ramifications are provided for educators with national implications for the education of urban African American males who are potential achievers. Included are 5 tables and 20 references. (JB)
