This paper addresses the concerns of physical educators who must implement coeducational programs in secondary school physical education. Title IX regulations which relate directly to physical education are presented as well as the Oregon Administrative Rules. The paper covers eight concepts of federal and state regulations that have direct impact on physical education. These concepts are: (1) locker room supervision; (2) facilities and equipment; (3) scheduling; (4) assessing skills; (5) contact sports; (6) grouping by ability; (7) leadership and staffing; and (8) disproportion in classes. For each concept, an interpretation of the law and the law's effect is presented, and recommendations are suggested for implementation. (JD)
