This paper and a set of correlated video tapes were prepared to be used especially by school personnel interested in the Multiunit school which provides a facilitative environment for three functions: (1) modifying current practices and developing an effective system of individually guided education within each building; (2) participating in research, development, and dissemination activities that are essential to the continuous refinement and extension of the system of individually guided education; (3) conducting relevant preservice and inservice education of teachers and other educational personnel. A rationale is presented for recommended changes in the elementary school by giving estimates of the current status of the typical age-graded self-contained elementary school and by hypothesizing the nature of elementary schools in the next decades. The Multiunit organization, the differentiated staff roles essential to the smooth functioning of the Multiunit school, and some implications for a system of individually guided education, for the education of teachers, and for research and development are described.
