This report describes the steps that were taken in developing and evaluating a conceptual and experiential approach to leadership training at the Reserve Officer Training Corps (ROTC) level. "U.S. Army ROTC Leadership Development: A Performance-Based Program" consists of two documents: a student manual and an instructor manual. The student manual includes the following: (1) the platoon leadership experience; (2) the theoretical basis for effective platoon leadership; and (3) instruction and exercises in the skills that are necessary for effective platoon leadership. The instructor manual provides lesson plans and guidance for using the program. The program received field evaluations during 1981, 1982, and 1983. The report presents the reactions to the program and a discussion of changes that were made. In addition, a description of the teaching materials currently being used for leadership training by ROTC detachments is presented. (Extensive appendixes to the report contain materials about leadership qualities and the questionnaires used in the research.) (Author/KC)
