Schools worldwide are banning phones. New research published today reveals what happens when they do—including unexpected consequences.
What’s happening: A new study published today examined what happened after schools implemented cellphone bans, tracking both academic performance and discipline rates over multiple years. The research found that test scores improved, especially in schools where students previously used phones heavily during the day. However, the gains came with tradeoffs that schools weren’t anticipating.
Why this matters to all parents: School phone bans are spreading rapidly across developed countries. The UK implemented restrictions through its Online Safety Act. France banned phones in primary and middle schools in 2018. Sweden, Italy, and the Netherlands have introduced similar policies. Most of these bans were based on anecdotal reports from teachers rather than hard evidence about what actually happens.
The bigger picture: For the first time, parents have concrete data about the real effects of removing phones from schools—both positive and negative. This research helps families understand what to expect as these policies become the norm worldwide.
Here’s what the study found, which effects appeared immediately versus over time, and what parents should consider as schools implement these policies.
What Parents Need to Know
The research tracked schools over multiple years. Rather than taking a snapshot, researchers examined what happened after cellphone bans were implemented, comparing schools where students previously used phones heavily versus schools with low phone activity. This approach helps isolate the effects of the bans themselves.
Academic performance improved in the second year. Average test scores on higher-stakes assessments went up by 1.1 percentiles more in schools where students previously used their phones frequently, compared with low-activity schools. Importantly, the first year showed smaller gains—suggesting it takes time for benefits to appear.
Secondary school students showed greater improvement. The effects were more significant for older students (ages 11-18) than primary school children.
Boys benefited more than girls. Male students showed greater academic gains from the phone bans than female students, though researchers don’t yet understand why.
But discipline problems increased initially. Schools saw more disciplinary actions after implementing bans, particularly in the first year. This suggests enforcement of phone policies creates new behavioral challenges during the transition period.
The story behind the research: One school administrator remembers the moment that led to their phone ban. Two students planned to fight during a break. Staff intervened and prevented the violence—but hundreds of other students still rushed to the location hoping to watch, with phones ready to record. The fight had been advertised through messaging apps and group chats.
This research fills a critical gap. School leaders worldwide have reported dramatic changes in school culture after banning phones—more conversation during lunch, less cyberbullying, better classroom attention. But until now, there’s been little systematic evidence about measurable outcomes.
The policies vary by country: France’s 2018 ban prohibits phone use for students up to age 15. The UK’s approach focuses on restricting access to harmful content rather than banning devices. Some countries allow phones on school grounds but require them to be switched off. Others require phones to be stored in lockers or pouches.
What Other Parents Are Doing
Recognizing the adjustment period: Parents whose children’s schools have implemented bans report that the first few months are challenging. Students express anxiety about not having immediate contact with parents during emergencies, but most adjust within a term.
Preparing children in advance: Some families whose schools announced upcoming bans are practicing phone-free periods at home to help children adjust before the policy takes effect.
Appreciating the focus benefits: Many parents whose children were in high-phone-use environments before bans report noticing improved concentration on homework and better engagement during family time in the evenings.
Questioning the timing of benefits: Parents are learning from this research that improvements may not appear immediately. Some families whose children just started at schools with bans are now understanding why they haven’t yet seen dramatic changes.
Discussing enforcement approaches: Parents are asking schools how they plan to handle violations fairly, particularly after hearing about increased discipline rates during transition periods.
How This Affects Your Family
If your child’s school has a phone ban:
Understand that benefits may not appear immediately. This study found more significant effects in the second year, suggesting schools and students need time to adjust to new norms before academic improvements become evident.
Talk with your child about the transition: Ask how they’re managing without their phone during the day. Are they finding it easier or harder to focus? Do they feel less distracted by what’s happening online?
Monitor for changes over time: If your child’s school banned phones this year, academic benefits may become more apparent next school year rather than immediately.
Consider your child’s previous phone use: Students in schools where phone use was previously high showed the greatest academic improvements. If your child was constantly checking their phone during breaks and lunch, they may benefit more than peers who rarely used phones at school.
If your child is a boy: Research showed boys benefited more from phone bans in terms of academic performance, though discipline rates also increased. Talk with your son about following the rules carefully during the adjustment period.
Questions to ask your school:
- What happens during the first year as students adjust?
- How will you enforce the policy fairly?
- What’s your communication protocol if parents need to reach students?
- Are you tracking whether the ban affects academic performance?
- What support will you provide during the transition period?
For secondary school parents specifically: The study found stronger effects for students ages 11-18. If your teenager is in a school implementing a ban, they’re more likely to see academic benefits than primary-aged children—but also more likely to struggle initially with the adjustment.
The emergency communication question: Parents worldwide worry about emergencies when students can’t access phones. Schools implementing bans need clear protocols for how parents can reach children during school hours, and how schools will contact families if needed.
Conversation starters with your child:
- “How do you feel about not having your phone at school?”
- “Are you able to concentrate better in lessons without phones around?”
- “What do you do during breaks now instead of being on your phone?”
- “Have your friendships changed since the ban started?”
Understanding the discipline increase: Schools may see more rule violations initially as students adjust. This doesn’t necessarily mean the policy is failing—it may indicate a transition period where new norms are being established.
The long-term question: This study provides evidence that phone bans can improve academic outcomes, but schools need to be prepared for challenges during the first year of implementation. Simply removing phones isn’t enough—schools need clear enforcement strategies and support systems.
What this means for schools still deciding: Schools considering phone bans should use this research to plan for both immediate challenges and longer-term benefits. The evidence suggests these policies can work, but require patience and consistent implementation.
If your country is considering national policies: This research may inform policy discussions in countries debating whether to implement nationwide school phone restrictions. The evidence shows measurable academic benefits, but also highlights the importance of supporting schools through the transition period.
