In public schools, which case allows schools to regulate student speech that could disrupt learning?

• A. Hazelwood v. Kuhlmeier
• B. Bethel School District No. 403 v. Fraser
• C. Mapp v. Ohio
• D. Tinker v. Des Moines

Answer: (D)

The main idea here is that student speech in public schools is protected, but schools can regulate expression when it would cause a substantial disruption to the learning environment. This principle comes from Tinker v. Des Moines, where the Court held that students do not shed their First Amendment rights at the schoolhouse gate, and school authorities may regulate speech only if it would substantially disrupt the operation of the school or interfere with the rights of others. The armbands in that case illustrated that even unpopular or controversial viewpoints are protected unless there is a credible risk of significant disruption to the educational process. By contrast, other cases deal with different contexts: Hazelwood v. Kuhlmeier concerns school-sponsored curricular speech, Fraser addresses lewd student speech at school, and Mapp v. Ohio involves the exclusionary rule in criminal procedure. So, the case that directly supports regulating student speech when it could disrupt learning is Tinker v. Des Moines.
