Mentoring is a continuing process wherein individuals within an organization provide support and guidance to others (mentees or proteges) to help them become effective contributors to organizational goals. Although mentoring can enhance both teacher and administrator effectiveness, this paper focuses on developing mentoring programs for aspiring, beginning, and practicing administrators. To help school districts overcome program development difficulties, a planning model for use in individual school districts or consortia of school systems is presented. The mentor planning model consists of four steps: (1) initial program planning and development (including forming a mentor planning team and deciding who will be mentored); (2) program implementation (involving issues such as identifying and training mentors, matching mentors with proteges, and developing specific mentoring skills); (3) program assessment and revision; and (4) future directions (developing additional professional development activities for administrators). The rationale for starting a mentoring program and possible benefits for mentors, proteges, and districts are discussed. (MLH)
