Tinker v. Des Moines is a landmark 1969 Supreme Court case about student free speech in public schools. It began when students wore black armbands to protest the Vietnam War and were suspended by their school district.
The case matters because it confirmed that young people have constitutional rights, including First Amendment rights, while they are at school. It also helped define the balance between student expression and a school’s responsibility to maintain order.
The Supreme Court ruled that schools cannot punish student speech simply because it is unpopular, controversial, or political. Instead, school officials must show that the expression would cause a material and substantial disruption to school activities or interfere with the rights of others. This standard is still used when courts evaluate many student speech disputes.
Tinker also shows that constitutional rights often have limits based on context, safety, and the rights of the school community.

Vocabulary

Common Mistakes to Avoid
- Saying students have no free speech rights at school is wrong because Tinker says students keep First Amendment protections in public schools.
- Assuming all student speech is protected is wrong because schools can limit speech that causes substantial disruption or violates the rights of others.
- Calling the armbands regular clothing is incomplete because the Court treated them as symbolic speech carrying a political message.
- Thinking a school can ban speech only because administrators dislike the message is wrong because disagreement or discomfort alone is not enough under Tinker.
Practice Questions
- 1 In Tinker, the Supreme Court vote was 7 to 2. What fraction of the justices sided with the students, and what percent is that to the nearest tenth?
- 2 A school has 1,200 students. If 5 percent of students wear armbands in a peaceful protest and no classes are interrupted, how many students wear armbands?
- 3 A student wears a shirt with a political message, and the school wants to ban it because some people may disagree with it. Using the Tinker standard, explain what the school would need to show before it could punish the student.
