For decades, camps have served as outdoor learning laboratories for leadership development. Camps provide adolescents the opportunity to practice leadership skills through activities perceived as worthwhile and in environments that differ profoundly from everyday experience. A survey examined the self-perceived development of leadership skills at camp among campers and staff. The 21-item modified Leadership Skills Inventory was completed and returned after the 1999 camp season by 137 campers, 22 counselors-in-training, and 72 camp staff at Camp Ondessonk, a wilderness-based youth camp in southern Illinois. Leadership development is not an explicitly stated goal of the camp for campers or staff. Nevertheless, after the camp experience, all three groups of subjects had increased self-perceptions of their leadership skills, both overall and for each of five subscales related to communication, decision making, working with groups, understanding self, and positional leadership. Male and female respondents differed on several subscales. (Contains 19 references and 4 statistical data tables.) (SV)
