This paper discusses the development of research-based guidelines and strategies for training both inservice and preservice elementary school educators in parent involvement. These guidelines provide information that should effectively develop teachers' knowledge, understanding, and skills regarding communication with parents and strengthening the relationship between homes and schools. Major recommendations from previous research are discussed and a description is given of how the guidelines were developed for teacher-trainers in parent involvement. Guidelines and strategies are presented for training teachers about parent involvement in both childrens' learning and in shared educational decision making. It is suggested that these guidelines may be used as a framework for developing courses or parts of courses, modules, seminars, or workshops on parent involvement. (JD)
