The purpose of this guidebook is to encourage activities advisors and directors to teach their student advisees, in the regular classroom setting, how to become effective leaders, and to provide school administrators and curriculum directors with a sound rationale for leadership classes. The booklet describes the need for leadership instruction for students, pointing out that leadership, like other skills, must be developed through training. Suggested course objectives, content, and methods of instruction for secondary school leadership classes are outlined. The appendix contains descriptions of leadership programs and courses at four secondary schools. (Author/DS)
