What standard did Tinker v. Des Moines establish for limiting student speech?

• A. Substantial disruption standard
• B. Clear and present danger test
• C. Imminent lawless action standard
• D. Public safety exception

Answer: (A)

The key idea is that students don’t lose their constitutional rights at the schoolhouse gate, but schools may regulate student expression if it would substantially disrupt school operations. In Tinker v. Des Moines, the Court held that wearing armbands to protest the Vietnam War was protected speech as long as it caused no substantial disruption. That protection only gives way when the speech would significantly interfere with the school's ability to govern itself or infringe on others’ rights.

This is why the substantial disruption standard is the best answer. The other options refer to different contexts: the clear and present danger test addresses wartime or urgent threats, the imminent lawless action standard targets incitement, and the public safety exception relates to Miranda rights.
