School phone bans: do they actually work?

More than half the world's school systems now restrict phones in some way. The evidence is cleaner than the culture war suggests, but it does not say everything the headlines claim.

Test scores rose

The best-known study found scores improved after bans, roughly an extra hour of schooling a week.

Lower achievers gain most

The benefit was largest for struggling students, while high achievers changed little.

Spreading fast

By 2025 well over half of countries had some national school phone restriction, up from a quarter in 2023.

01A fast-spreading policy

School phone bans have gone from rare to mainstream in just a few years. By 2025, well over half of countries had introduced some national restriction on phones in schools, up from roughly a quarter in 2023. Educators point to distraction, disruption, and reduced attention as the drivers, and many governments have chosen to act rather than wait for perfect evidence.

02What the best study found

The most cited evidence comes from a study by Beland and Murphy in England, which looked at schools introducing phone bans. They found that test scores improved after the bans, by an amount roughly equivalent to an extra hour of schooling each week. For a simple, low-cost policy, that is a meaningful result.

It is worth noting this is about exam performance, where the evidence is reasonably clear, rather than broader claims about wellbeing.

03Who benefits most

The most striking finding was about who gained. The improvement was largest for lower-achieving students, while high achievers showed little change. The likely explanation is that students most prone to distraction had the most to gain from a calmer, phone-free environment.

That makes phone bans an unusually equity-friendly policy: they appear to help the students who struggle most, without holding anyone back. What matters for results is usually consistent, whole-school enforcement rather than patchy classroom-by-classroom rules.

04Where the claims overreach

The honest truth: Phone bans are not magic. The solid evidence is about attention and test scores. The popular claim that bans fix teen mental health goes well beyond what the research shows. Bans reduce in-class distraction; they do not address what happens on phones the other sixteen hours of the day. Expect a calmer classroom, not a cure for everything.

Used realistically, a ban is a sensible classroom-management tool, best paired with the wider approaches in the kids and screens pillar.

05Common questions

Do school phone bans improve grades?
The best-known study found test scores rose after bans, equivalent to a small but real boost, with the largest gains for lower-achieving students.
How common are school phone bans?
Very, and growing fast. By 2025 well over half of countries had some national restriction on phones in schools, up from about a quarter in 2023.
Who benefits most from a ban?
Lower-achieving students tend to benefit most, likely because they are most affected by distraction. High achievers show little change in the research.
Do phone bans fix teen mental health?
There is no good evidence for that. Bans can reduce classroom distraction, but claiming they fix mental health goes well beyond what the research shows.
What makes a phone ban effective?
Consistent, whole-school enforcement tends to matter more than the exact rule. Patchy, classroom-by-classroom policies are harder to make work.
