The School Community Involvement System (SCIS) is presented as a model community program that encourages educators, parents and community members to work together to meet the needs of children and society. This model is intended as a comprehensive systematic program for community involvement and communication in the school experience, as well as a guide for principals and faculties in developing or upgrading community involvement programs. The rationale for parent and community involvement in the schools is discussed, various levels of involvement are described, and parental rights to information and influence are explained. The goal of SCIS is described as the development of a true community school with three major components: (1) a community advisory council; (2) an involvement program (school-based); and (3) an involvement support system (community-based). Personnel needed and services provided by each component are detailed along with four alternative procedures for implementation of a SCIS program. (NRB)
