Teacher leaders often teach full- or part-time while assuming leadership responsibilities. Also, they have often learned new roles just by doing the tasks demanded by those roles. A more systematic approach to helping teachers develop the requisite skills for assuming leadership roles (e.g. department chairs, team and grade leaders, and curriculum committee chairs) is discussed. Emerging opportunities for leadership include three programs: beginning teacher assistance programs, school-centered decision making (site-based management), and professional development schools. Six leadership roles have been identified, which might serve as organizers for the descriptive reports on the formal programs to develop leadership skills: (1) continuing to teach and improve one's own teaching; (2) organizing and leading peer reviews of school practice; (3) providing curriculum development knowledge; (4) participating in school-level decision making; (5) leading in-service education and assisting other teachers; and (6) participating in the performance evaluation of teachers. The digest recommends a more concerted effort to develop programs to replace learning on the job as well as to evaluate teacher leader programs. (SM)
