Why do secondary schools follow the practice of having student assemblies? What are these assemblies expected to accomplish? Who should be involved in planning them? What types of programs best suit educational, cultural, and informational purposes? How can systematic evaluation or appraisal of student assemblies be achieved? These and similar questions may be easier to ask than to answer. That is why the National Association of Student Councils presents this booklet as the fourth in the New Directions for Student Councils series--to provide guidelines for planning, scheduling, and producing a balanced long-range student assembly schedule.
