A three-stage model was designed to improve leadership training and improve instruction for Indiana vocational youth organizations. The model was field tested using a pretest-posttest, control-group design administered to five classrooms representing each of six vocational youth group organizations. Both formative and summative data were collected. On the basis of the summative evaluation results for stages one, two and three of each unit, it was concluded that the leadership units were effective. Students learned basic knowledge concerning leadership skills, they applied this knowledge in small group simulation projects, and they developed attitudes and a personal relevance for leadership as a result of individual projects.
