This study investigates how informed New York State middle school teachers (N=190) in public schools are about school law and case law which impacts on them in their professional roles. The study focuses on four areas: teacher rights and responsibilities, student rights, instruction, and health and safety. In addition to assessing subjects' overall understanding of school law, the study seeks to determine specific areas in which teachers may be deficient and to explore possible relationships between level of understanding and gender, type of school (i.e., urban, rural, suburban), and years of teaching experience. The average score of the 190 middle school teachers was 59 percent correct on the 35-item questionnaire. The sample was most deficient in the area of instruction (47 percent) and most knowledgeable in the area of student rights (73 percent), followed by health and safety (60 percent), and teachers' rights and responsibilities (57 percent). The "Questionnaire on School Law," which was used in the study, is found in the appendix. (IAH)
