When students went back to school this fall, most of them walked into a building with a phone rule written into state law. A year ago that was true in only a handful of states. Now, according to Education Week’s tracker, 31 states either have cell phone limits in place or are putting them in place for the 2025-26 or 2026-27 school year. Some see these bans as heavy-handed. The reasons behind them are worth understanding, though, because the decision now sits with every principal, teacher and parent who has to make one work. This piece looks at why so many states are saying ‘no’ to phones during the school day, what the research does and does not show, and what makes a school-wide ban hold.

Where the States Stand This Fall

Four states set a single statewide rule that every school follows, and the rest require districts to write their own policy within limits the state sets. A few of the rules that took effect for this school year:

1. New York: Since September 2025, every K-12 public school must restrict smartphones from the first bell to the last, under a plan each district wrote for its own buildings (Governor of New York).
2. Texas: House Bill 1481, signed June 20, 2025, requires every district and open-enrollment charter school to adopt a policy on student use of personal communication devices during the school day.
3. Florida: The state that started the trend in 2023 went further with House Bill 1105, approved May 30, 2025. Elementary and middle school students may not use phones at all during the school day, high school students may not use them during class, and six counties are piloting a full-day ban in high school.
4. Louisiana, South Carolina and Utah: Along with Florida, these are the states with one statewide policy that all schools follow (Education Week).
5. Virginia: Governor Glenn Youngkin’s 2024 executive order directed schools to go cell phone-free, and districts have had a full year of it.

Other states, Delaware and Pennsylvania among them, offer money to districts that adopt a ban rather than requiring one. Whatever the state law says, your own district’s policy is the one that governs your classroom, so read it.

Why More States Are Saying ‘No’ to Cell Phones in the Classroom

Phones are part of daily life, so it is no surprise they came into the classroom with students. Teachers have been saying for years what that costs. In a Pew Research Center survey taken in fall 2023, 72% of high school teachers called students being distracted by phones a major problem in their classroom, compared with 33% of middle school teachers and 6% of elementary school teachers. Here are the reasons states and schools give most often.

1. The Distraction Factor

Notifications, messages and social media pull attention away from the lesson, and the pull does not stop when the phone is face down. In the “Brain Drain” study, researchers at the University of Texas at Austin found that the mere presence of one’s own smartphone reduced available cognitive capacity, even when the phone was turned off. A later review of the studies that followed confirmed the effect while finding it small, strongest for memory. A phone in a locker or a pouch is a phone that is not competing with the lesson.

2. Promoting Face-to-Face Interaction

Without phones, the minutes between tasks, the lunch table and the hallway go back to being places where students talk to each other. Lab partners have to negotiate, groups have to discuss, and the quiet student gets drawn into a conversation rather than a screen. These are skills students build only by practicing them, and a phone-free day gives them hours more practice.

3. Reducing Cyberbullying During the School Day

A phone in the hand during school makes it easy to photograph a classmate, post it and share it before the period ends. Taking phones out of the school day does not end online cruelty, but it removes the school building as the place where the picture is taken and the post goes up, and it takes the instant audience out of the room.

4. Improving Academic Performance

Every minute a student spends checking a phone is a minute of instruction missed. Schools adopt bans expecting focus, and with it learning, to improve. The evidence on test scores is still coming in. A study of 30 schools in England, published in February 2025, found that students in restrictive schools used their phones about 30 minutes less during the school day, but found no difference in grades, sleep or mental wellbeing, partly because students made up the time after school. A ban is a start, not the whole answer.

5. Teaching Responsibility and Self-Control

Learning when a phone belongs in your hand and when it does not is a skill. A clear rule, the same in every classroom, takes the daily negotiation off the teacher and gives students a routine to follow. Many students, once the habit is broken, say they are relieved not to have to keep checking.

6. Reducing Cheating

A phone gives a student the internet, a camera and every classmate’s number in one pocket. Sharing a photo of a test or looking up answers takes seconds. With phones stored away, teachers spend less time watching for devices and more time teaching, and students who do their own work are not at a disadvantage.

7. Improving Teacher-Student Relationships

Every time a teacher has to ask a student to put a phone away, the relationship takes a small hit. A school-wide rule moves enforcement from the individual teacher to the school, so class time can go back to teaching and the teacher is no longer the phone police.

8. Preparing Students for the Workplace

Most workplaces, laboratories and shops limit personal phone use, and in many of them a distracted worker is a safety risk. Practicing focus for a full school day prepares students for jobs where giving the task full attention is not optional.

Making a School-Wide Ban Work

A ban written on paper and a ban that holds are different things. Six in ten high school teachers whose schools had a phone policy told Pew that it was difficult to enforce. Schools that make a ban stick tend to do the same things:

1. Store phones away from the student. A locker, a locked pouch or a numbered caddy at the classroom door works better than “keep it in your bag.”
2. Write down the exceptions. Students with medical needs, disability accommodations or language needs may need a device, and Texas’s law, like most, provides for them.
3. Tell families how to reach their child. Parents worry about emergencies. Give them the front office number and explain how the school will reach them.
4. Enforce the rule the same way in every room. A rule that applies in one classroom and not the next teaches students to wait it out.
5. Plan for the first weeks. Expect pushback while habits change, and decide in advance how violations will be handled.

Conclusion

The move to take phones out of the school day has gone from a few states to most of the country in barely two years. The early evidence says a ban reliably reduces phone use at school, while its effects on grades and wellbeing are still being measured. That is a reason to run a ban well, not a reason to skip one. For educators, the job now is to make the rule clear, consistent and humane, and then to use the attention it gives back. A classroom where every student is present for the lesson is worth the effort.
