Teacher perceptions of authority structures in three types of schools were studied. Teachers at Multiunit schools, Individually Prescribed Instruction (IPI) schools, and control schools were questioned as to who made certain decisions and what was the nature of the relationships of the people involved in a particular decision. This report discusses the results found at the various types of schools. In the control schools, the teachers have more autonomy, but have access to consultants for special problems. In the Multiunit schools, the teachers exercise less individual autonomy, but participate in making decisions at the unit level. In the Individually Prescribed Instruction schools, the teachers relinquish some of their authority in order to spend more time with individual students. (JY)
