These documents (IGE booklet and accompanying mailing piece) provide information about the multiunit elementary school (MUS-E). The MUS-E is the organizational administrative component of a system of individually guided education (IGE) designed for the elementary school. The MUS-E and IGE are designed to formulate and carry out instructional programs for individual children in which planned variations are made in what each child learns, how rapidly he learns, and how he goes about learning.
