This document describes the involvement of the Individually Guided Education/Secondary Project (IGE/S) with a Wisconsin middle school from March 1975 to June 1976. The guiding purpose was to conceptualize and implement a change process that would aid schools to become IGE places of learning. A sequence of change operations was followed and the activities that were carried out are presented. The five phases in this sequence were an awareness phase, a commitment phase, a changeover phase, a refinement and implementation phase, and a renewal phase. The focus for all activities in each of the phases was a target program of individualization that was cooperatively developed and subsequently implemented. This target program, its implementation, and the results obtained are presented. (Author)
