This guide assembles examples of staff development used by one large school district, Los Angeles Unified School District, to prepare teachers for the new role of mentor. In an effort to help mentors get off to a good start, the district's Professional Development Center assembled a 30-hour program of discussion panels, skill training, and problem solving groups. Four sections of the guide represent the original 30-hour core training: (1) Orientation to the Mentor Role; (2) Assisting New Teachers; (3) Classroom Organization and Management for New Teachers; and (4) Classroom Consultation, Observation and Coaching. Two additional sections reflect revisons and additions now underway: The Mentor as Staff Developer and Cooperation between the Administrator and the Mentor. Each section begins with an overview of the topic and a brief preview of the concepts or skills developed in the individual segments. Each section ends with a short inventory of other resources and references. Numerous handouts and transparencies are also included. (SI)
