School Phone Bans Work Better Than Headlines Suggest

Students are putting down their phones at school, and they're doing better than you might think.

A new study from Stanford, Duke, Penn, and Michigan tracked over 40,000 schools using Yondr pouches, those magnetic cases that lock phones away during class. The headline news focused on flat test scores, but the full picture tells a more hopeful story.

The first big win is simple: kids are actually off their phones. Despite viral videos showing students hacking the pouches, GPS data and teacher surveys confirmed phone use dropped substantially during school hours. That alone matters.

Yes, there were growing pains. Suspensions jumped 16 percent right after schools locked up phones, but returned to normal within a year. Students lost their digital escape hatch and had to learn how to sit with boredom or frustration.

Student wellbeing dipped at first too. Imagine being 15 and losing your notification buzz for the first time ever during school. But here's the encouraging part: students adapted quickly and their wellbeing bounced back, even improving beyond where it started.

Test scores stayed mostly flat, with small gains in high school math. That disappointed some advocates, but the earliest schools in this study only started banning phones in 2022. Healing from years of distraction takes time.

The Bright Side

Teachers are seeing changes that don't show up on tests yet. Students are talking face to face for entire class periods, many for the first time. They're learning to handle discomfort without scrolling. They're present.

One teacher described the adjustment as "growing pains" worth enduring. She's watching teenagers discover they can survive without constant digital connection, a skill that will serve them far beyond any single test score.

The study's lead researchers, including prominent experts Tom Dee and Angela Duckworth, used data from schools, GPS tracking, and surveys of students, parents, and teachers. They compared schools that adopted pouches between 2023 and 2025 with schools that waited longer or never used them.

What matters most is that schools aren't giving up. The bans are holding, students are adapting, and teachers finally have support after years of fighting the cellphone battle alone with shoe organizers and broken policies.

Breaking even on attendance and academics while dramatically reducing phone use isn't failure. It's the foundation for something better.
