This article examines the application of First Amendment principles to web sites that were created by students. Schools sometimes attempt to regulate the speech of students on such web sites by imposing disciplinary sanctions on the students who create the sites. The ability of schools to take such action depends on the interplay of a variety of factors, including the location at which web site was created (on or off campus), whether the web site was disseminated on campus, the extent to which the site caused disruption at the school, and the nature of the expression on the website. The article discusses the applicable case law and concludes with some practical guidelines that can be applied by school administrators who find that they are considering disciplinary action against students with regard to student created web sites.
