Membership is based on scholarship, leadership, and service.
Members must be at least in their junior year or in the equivalent status. All members must be elected from students with a GPA representing the upper thirty-five percent of the junior class or a minimum of a straight B average, whichever is higher on any given campus. A chapter may raise its scholastic requirement with the consent of the National Office annually. Resolutions and the National Project passed at National Conference serve as a guide for chapter action.
