How the First Amendment Protects Student Speech

If you’re a public school student, you don’t check your constitutional rights at the schoolhouse doors. But whether schools can punish you for speaking out depends on when, where, and how you decide to express yourself.
Do I have First Amendment rights in school?
Yes. You do not lose your right to free speech just by walking into school. You have the right to speak out, hand out flyers and petitions, and wear expressive clothing in school — as long as you don’t disrupt the functioning of the school or violate the school’s content-neutral policies.
What counts as “disruptive” will vary by context, but a school disagreeing with your position or thinking your speech is controversial or in “bad taste” is not enough to qualify. Courts have upheld students’ rights to wear things like an anti-war armband, an armband opposing the right to get an abortion, and a shirt supporting the LGBT community. And “content-neutral policies” means rules that have nothing to do with the message you’re expressing, like dress codes. So, for example, a school can prohibit you from wearing hats — because that rule is not based on what the hats say — but it can’t prohibit you from wearing only pink pussycat hats or pro-NRA hats.
Can students be punished for refusing to stand for the pledge? 
Arkansas students may choose to exercise their First Amendment rights by opting not to stand for the Pledge of Allegiance or the National Anthem at their schools. Schools may not punish students for refusing to stand for the Pledge or to salute the flag. Any such punishments violate the fundamental rights of your students as shown in clear U.S. Supreme Court decisions.

Arkansas state law also recognizes that the Constitution prohibits compelling a student to demonstrate his or her patriotism or loyalty. While state law requires recitation of the Pledge of Allegiance each day at school, it also protects a student’s right not to stand and recite the Pledge of Allegiance as required by the U.S. and Arkansas Constitutions. 
Can my school discipline me for participating in a walkout?
It depends on the time, place and manner of your activity. If the demonstration or walkout takes place during non-instructional time when other non-classroom activity takes place or is allowed, and you aren’t disrupting classroom time, you should not be disciplined.  If you miss class or part of class, you may be disciplined for missing class. But what they can’t do is discipline you more harshly because of the political nature of or the message behind your action.
The exact punishment you could face will vary by your school district, and school. Find out more by reading the policies of your school and school district. If you are planning to miss class, look at the policy for excused absences and whether you can satisfy that policy and also look at the policy for unexcused absences. If you are facing a suspension of 10 days or more, you have a right to a formal process and can be represented by a lawyer. Also, you should be given the same right to make up work just as any other student who missed classes.
Find out the rules so you can tell if they are being applied differently when it comes to your walkout.
What about for protesting away from school?
Outside of school, you enjoy essentially the same rights to protest and speak out as anyone else. This means you’re likely to be most protected if you organize, protest, and advocate for your views off campus and outside of school hours.
What are my rights on social media?
You have the right to speak your mind on social media. Your school cannot legally punish you for content you post off campus and outside of school hours that does not relate to school. Some schools have attempted to extend their power to punish students even for off-campus, online posts. While courts have differed on the constitutionality of those punishments, the ACLU has challenged such overreach.
