This paper discusses the adoption of mandatory and voluntary uniform policies in school systems across the United States. Mandatory policies have been adopted by 6 of the nations largest districts--Birmingham, Chicago, Dayton, Long Beach, San Antonio, and Oakland. Approximately 35 other districts have voluntary policies, and countless others are considering implementation of some type of uniform policy. The trend toward uniforms actually began in the late 1980s, primarily in inner-city location. The paper discusses the factors that have encouraged the adoption of a school uniform policy as well as what opponents of such a policy have to say. Legal challenges to uniform policy have arisen as school districts have adopted mandatory uniform codes. (Contains 25 references.) (DFR)
