The legal system has significantly influenced the everyday operation of American public schools in the last 20 years. Because of the increasing probability of teacher involvement in a legal incident, a working knowledge of the law as it relates to physical education is important. Included in this document, which focuses on tort liability for negligence, are discussions of the Oregon Tort Claims Act, the Oregon court approach to negligence theory and defenses under Oregon law, and duties of physical educators. Each section summarizes legal concepts and presents reported appellate decisions that were reviewed as of July 1988. Thirty-six guidelines for reducing risk and providing more positive student experiences are offered. (18 references) (LMI)
