The relationships among students' reports of learning outcomes based on leadership experiences in various types of student organizations and various roles within organizations were investigated. Relationships between demographic variables (i.e., ethnicity, gender, age, and type of housing) and type of organization, role within an organization, and learning outcomes, were also examined. A new instrument, the Student Leadership Learning Outcomes Assessment (SLLOA), was created to measure student generated learning outcomes; it has good internal consistency and validity. The SLLOA was completed by 328 student leaders at a private southeastern university. SLLOA scores indicated student leaders in cultural and service groups reported learning more than student leaders in sports/athletic groups. Vice Presidents and Presidents reported learning more from the leadership experience than Treasurers. Female student leaders reported learning more than male. Relationships were found between ethnicity of student leaders and type of organization and between type of housing (i.e., on campus, off campus without parents/parental figures, off campus with parents/parental figures) and type of organization. There was no relationship between type of organization and leaders' gender and age, or between the role held and leaders' gender, ethnicity, and type of housing. The results revealed no relationship between ethnicity and SLLOA scores.
