This monograph analyzes and summarizes judicial decisions relevant to the control of student conduct by school officials. It is an expansion and revision of a monograph published by the same author in 1970. Extensive revision of the earlier work was necessary because the number of appellate court decisions involving student conduct has grown rapidly in recent years as a result of increased reliance on the courts as the means to resolve conflicts between students and school authorities. The author first describes the general legal framework that applies to student discipline and then examines court decisions relevant to various specific areas of student conduct, including dress and appearance, insignias and emblems, publications, secret societies, and marriage and parenthood.
