ADM Figures

The OSAA classifies public high schools based upon the Average Daily Membership (ADM) shown on the Annual Report submitted by the Department of Education to the Superintendent of Public Instruction at the close of the previous school year. Private high schools shall be classified based upon the ADM computed by the OSAA. The OSAA shall compute private school A.D.M. by determining the average of the actual enrollment reported to the OSAA by private schools for four dates (September 30, December 31, March 31, last day of school) during the previous school year. Grades 9, 10, 11 and 12 shall be used as a base to determine the classification figure. The coeducational school shall be used as a base. For a non-coeducational school, the A.D.M. shall be doubled to determine the classification figure.
