One hundred twenty-five Chicago (Illinois) area elementary and secondary school teachers were surveyed through responses to a 44-item questionnaire to determine the extent of their knowledge of school law. Many of the questions were based on Illinois school law, and the findings are qualified by local school district practice and the simplification of complex legal issues in the questionnaire. The findings were examined on the basis of those teachers who had taken a school law course (55 percent of the sample) and those who had not. The majority of teachers gave correct responses to most of the survey items, and teachers who had taken a school law course had a higher percentage of correct answers than those who had not. Among the topics addressed in the questionnaire were: (1) teacher liability in student injury; (2) teacher contracts and tenure; (3) legal implications of grades; (4) church-state relations; (5) teacher-school board relations; (6) teacher rights; and (7) student rights.
