Schools that banned phones noticed higher test scores and surprising improvements in focus

A study from the National Bureau of Economic Research reveals how phone bans help students focus, finding that schools that restrict cellphone use often see early challenges but long-term academic rewards, GMA reports.

The research suggests that removing phones from classrooms can initially lead to short-term discipline issues; however, once students adapt, their focus on academic tasks improves, and their grades rise.

This growing body of evidence supports what many educators have long suspected—that a cell phone ban in schools may be difficult at first, but it ultimately helps students thrive.

A difficult start for a promising change

The study examined a large urban district in Florida that had recently implemented a phone ban.

Under the new rule, students were required to keep their devices out of sight throughout the day. While the intention was to help restore student focus, the early months were far from smooth.

Researchers noted that the first year saw a steep rise in disciplinary issues.

Students struggled with the sudden digital detox, and teachers faced new challenges managing classrooms without constant interruptions from phones.

According to the study, the initial reaction was dramatic:

“Suspension rate more than doubled in the month after disciplinary enforcement started compared to the month before and was 25 percent higher compared to the same month in the school year right before the ban,” they wrote. “These heightened suspension rates persisted throughout the rest of the school year and returned to pre-ban levels in the second year.”

This early spike reflected the growing pains of any significant rule change. But by the second year, something remarkable happened.

Second year proves how phone bans help students focus

Once students adjusted to their new routine, the atmosphere in classrooms began to change. Teachers reported fewer disruptions, and learning activities became more engaging.

The data confirmed what many had observed—how phone bans help students focus becomes clearer over time.

By the second year of the cell phone ban in schools, suspension rates returned to normal, while student test scores improved.

Researchers recorded test scores that were roughly two to three percentiles higher than the year before the ban.

They also linked these academic improvements to the calmer environment that followed.

When students no longer had constant access to their phones, they paid more attention in class. They remained engaged for longer periods of time.

This renewed focus on students naturally led to improved grades and increased participation.

Fewer absences, better grades

Another key outcome of the phone ban was a noticeable drop in unexcused absences. Students were not only more physically present but also mentally engaged.

Without screens pulling their attention away, many became more involved in lessons and group work.

Researchers noted that the greatest improvements were observed among middle and high school students, who tend to rely on phones the most during the school day.

In contrast, elementary schools—where younger students have less access to devices—saw smaller shifts in their use of devices.

This pattern underscored how removing distractions has the most significant effect where the problem is greatest.

The digital detox that older students experienced helped them regain control of their time, resulting in improved grades and more consistent attendance.

The debate over phone bans in schools is growing nationwide

The debate over how phone bans help students focus has grown louder as more educators and parents speak out about classroom distractions and screen addiction.

The Florida district’s experience is now influencing schools across the U.S.

Currently, about 20 states have enacted some form of cell phone ban in schools, while 17 others, including Maryland, leave the decision to local school boards.

Even New York City has expanded its policy to include smartwatches, recognizing the continued evolution of technology.

Although the researchers noted that their findings show correlation rather than direct cause, the results provide a roadmap for other districts.

By understanding that discipline issues may spike in the first year, schools can better prepare for a smoother transition and minimize disruption.

How phone bans help students focus, learn better, and reconnect

Ultimately, this study presents a hopeful outlook on the modern classroom.

The findings make it clear that how phone bans help students focus goes far beyond theory—it’s a practical solution that improves concentration, academic performance, and classroom well-being.

The early months may test patience, but over time, the results speak for themselves.

Once students adapt to life without constant notifications, their attention strengthens, and their performance rises.

For many schools, adopting a phone ban is a tough decision.

However, as this research demonstrates, the short-term challenge ultimately leads to long-term success. This meaningful digital detox enables students to reconnect with learning, their teachers, and one another.
