A description is presented of a classroom management training program developed for preservice and inservice teachers in Guam. A brief review of research findings on classroom management and effective teacher practices includes a profile of an effective classroom manager. The training program, based upon these findings, is designed to focus workshops on the following topics: (1) getting ready for the beginning of school; (2) planning routines and procedures; (3) managing student behavior; (4) organizing and conducting instruction; and (5) managing special groups. Preservice training is offered immediately prior to student teaching and in association with observation or participation in a public school classroom. Sessions are conducted twice a week for one semester. Inservice training is delivered through a series of interrelated training sessions over a one-year period. Sample workshop agendas for inservice teachers are outlined and events in the preservice training are listed. (JD)
