This report examines student activity scheduling procedures in the nation's high schools and investigates the prevalence of student activity directors assigned to these schools. In addition, it provides 11 sample job descriptions for student activity directors as submitted by responding school systems. The data reported in the document are based primarily on surveys by the National Association of Secondary School Principals and the Educational Research Service, Inc. The ERS survey of 576 school systems indicates that nerarly half of the school districts schedule all student activities after school. Roughly 37 percent of the respondents indicated that all activities are scheduled throughout the day in some or all of their high schools. Twenty-three percent of the schools indicated they had full-time activity directors in the high schools. Medium and large school systems reported the highest percentage of directors. A short list of references is included in the report. (Author/DN)
