Student-led responses to Operation Metro Surge are increasing. We’ve seen walkouts at all three high schools in District 728. It’s a good time to review students’ rights under the Constitution. Students do not abandon their rights when they enter the school. Schools and school districts must protect those rights. This post looks at the Supreme Court decision that defines those rights. We also provide examples of student actions that would or would not be protected.
December 1965: A Nation Divided
In 1965, the United States was increasingly divided over the war in Vietnam. American combat troops had been sent to Vietnam earlier that year. By year’s end, troop levels had jumped from 23,000 to over 184,000. For the first time, television brought images of combat into American living rooms. The draft affected many young men. The antiwar movement was gaining strength on college campuses and in cities. But war supporters, still the majority, saw the protesters as unpatriotic or even treasonous.
In this tense climate, a group of students and adults in Des Moines, Iowa, decided to express their opposition to the war through a simple act. They would wear black armbands during the holiday season. The armbands would mourn those killed in Vietnam and support Senator Robert F. Kennedy’s proposal for a Christmas truce.
When school principals found out about the planned protest, they acted fast. They banned the wearing of armbands, fearing the disturbances this might cause. On December 16, 1965, John Tinker, fifteen, his thirteen-year-old sister Mary Beth, and Christopher Eckhardt, also fifteen, went to school wearing black armbands. All three were sent home and suspended.
The students didn’t shout. They didn’t march, block hallways, or disrupt classes. There was no violence. In fact, there was no disruption of any kind. But the schools took action anyway, banning the armbands based on fear of what might happen, including arguments among students and tension in classes.. The Tinker family, with help from the Iowa Civil Liberties Union, filed a lawsuit.
Four years later, on February 24, 1969, the Supreme Court issued its decision in Tinker v. Des Moines Independent Community School District. In his majority opinion, Justice Abe Fortas wrote “It can hardly be argued that either students or teachers shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.”
This decision set the standard for student speech rights that remains the law today. It also rejected the kind of action the Des Moines schools had taken—punishing students based on fear rather than actual disruption.
The Tinker Standard
The Tinker decision set a clear standard. Schools may restrict student speech only when:
• The speech would substantially disrupt school operations, OR
• The speech would materially interfere with the rights of others
Here’s what matters most: The Court said that “fear…of disturbance is not enough to overcome the right to freedom of expression.” School officials must point to “facts which might reasonably have led school authorities to forecast substantial disruption.”
In other words, schools need specific evidence that this particular speech would cause substantial disruption. Not minor inconvenience. Not administrative hassle. But genuine interference with the school’s educational mission.
In the Tinker case, the Court found no such evidence. The armbands caused no disruption. A few students made hostile remarks, but there were no threats or acts of violence. Classes went on. Instruction continued. The school’s fear of potential disruption, however genuine, couldn’t justify stopping the students’ peaceful, silent expression.
The Court emphasized what the students had not done: “They caused discussion outside of the classrooms, but no interference with work and no disorder. In the circumstances, our Constitution does not permit officials of the State to deny their form of expression.”
The Court also noted something important. The Des Moines schools allowed other political symbols, such as campaign buttons. The school had no general ban on controversial symbols. It specifically banned this symbol expressing this viewpoint about this war. That revealed the real motive: suppressing a particular message, not preventing disruption.
The Problem of Prior Restraint
The principle at the heart of Tinker goes beyond armbands. The decision stands against what constitutional law calls “prior restraint.” That’s when the government stops speech before any harm occurs, based on speculation about what might happen.
Prior restraints face an extremely high bar in court. Why? Because they let government silence speech based on fear rather than fact, and before the speech even happens.
When schools try to punish students for announcing they’ll participate in a future walkout or protest, they’re doing exactly this. They’re stopping speech based on fear of what might happen later, not on disruption that’s actually occurring.
Here are some examples to show what schools can and can’t do:
Example 1: The Announcement
A student posts on social media: “I’m walking out next Friday at noon to protest [issue]. Join me if you support [cause].”
The speech: Announcing intent, advocating for a cause, encouraging others to participate
Status under Tinker: Protected. The announcement itself doesn’t disrupt anything. No classes are disrupted. No students are prevented from learning. The speech simply discusses future action.
What schools can do: Prepare for potential absences. Communicate with parents. Apply standard absence policies if students do walk out.
Example 2: The Walkout Itself
Students leave class and walk out of the building during school hours.
The conduct: Missing class, being absent without permission
Status under Tinker: Can be disciplined under neutral absence and truancy policies that apply regardless of the reason for absence
What schools can do: Mark students absent. Apply existing consequences for unexcused absences. Require makeup work.
Example 3: Coordinated Expression
Students organize to all wear the same color clothing to school in support of a cause.
The speech: Silent, symbolic expression through coordinated dress
Status under Tinker: Protected unless specific evidence shows this expression would substantially disrupt. Guessing isn’t enough.
What schools cannot do: Punish students simply for coordinating their expression or making their views known
The key difference: Schools can address actual disruption when it occurs through their normal policies. They cannot punish speech about potential future conduct based on fear of what might happen.
This is exactly what the Des Moines school officials tried to do in 1965—ban expression ahead of time based on fear of disruption. The Supreme Court rejected that approach then, and the principle remains unchanged today.
The “Reasonably Likely” Loophole That Isn’t
In some cases, schools may try to use Tinker’s language by saying they’re prohibiting speech that is “reasonably likely to disrupt” school operations. This sounds like it follows Tinker, but it often doesn’t.
The problem: Announcing you’ll participate in a future protest isn’t automatically “reasonably likely” to substantially disrupt anything. Consider:
• A walkout planned for after school disrupts no instruction
• A walkout planned for lunch has minimal impact on educational activities
• A walkout planned weeks in advance gives the school time to prepare, possibly reducing disruption
• A student simply saying they personally plan to participate creates no disruption at all
Tinker requires specific evidence that this particular speech would cause substantial disruption of the school’s educational mission. Not just minor inconvenience. Not just administrative hassle. A blanket assumption that all announced protests will “substantially disrupt” doesn’t meet this standard.
Courts look beyond what a policy says to examine how it actually works. Just using the right words doesn’t make a policy constitutional if it still functions as prior restraint on protected speech.
What Tinker Permits and Prohibits
Understanding Tinker requires being clear about what schools can and cannot do:
What Schools CAN Restrict Under Tinker:
Speech that is itself disruptive: A student standing up in class and shouting protest slogans interrupts instruction. The speech itself causes immediate, substantial disruption.
Conduct that disrupts regardless of message: Blocking hallways, preventing other students from attending class, or interfering with school operations can be disciplined under neutral rules about time, place, and manner.
Speech with specific, evidence-based forecast of substantial disruption: If a student makes credible threats of violence or says they’ll incite immediate lawless action, schools can step in. But this requires concrete facts showing substantial disruption is likely, not just guesses or general worries.
What Schools CANNOT Restrict Under Tinker:
Political speech that causes mere discomfort: Other students or staff disagreeing with a message, finding it offensive, or being upset by it doesn’t count as substantial disruption. Democracy requires tolerance for disagreement.
Speech based on guesses about future disruption: Simply fearing that speech might lead to problems later isn’t enough. Tinker explicitly rejected this when school officials banned armbands based on fear of what might happen.
Organizing or advocating for future protest: Announcing plans to protest, encouraging others to join, or coordinating collective action is core political speech, the most protected type under the First Amendment.
Symbolic expression of controversial views: As Tinker itself shows, silent, peaceful expression of political views cannot be banned just because the views are controversial or because some people disagree.
The Bottom Line
Student speech rights aren’t unlimited, but they’re substantial and based on core constitutional principles. Schools can maintain order and address actual disruption. What they cannot do, no matter how they write their policies, is punish students for talking about, planning, or advocating for future protests before any disruption occurs.
Schools worried about disruption should focus on managing the actual conduct if and when it happens. They should not try to stop the constitutionally protected speech that comes before it.
The black armbands worn by three Des Moines students in December 1965 were simple symbols of conscience during a time of national division. The Supreme Court’s protection of those students’ right to wear them set a principle greater than any protest or cause. In America’s public schools, students keep their constitutional rights. Those rights cannot be taken away based on fear of what students might say or do. That principle remains as important today as it was nearly 60 years ago.
