Do phone bans in schools work? What the evidence shows

England's school phone guidance became statutory this year. Most US states now have a law of their own. So do phone bans in schools work? Partly — and the honest answer is better than either side of the argument admits. Bans reliably change the school day. They barely dent the daily total.

Where the rules stand

In England, the Department for Education published guidance on mobile phones in schools in February 2024 as advice. In June 2026 the revised version became statutory: schools should be phone-free by default, exceptions only where there's a reason. It covers England, not Scotland, Wales or Northern Ireland.

The US is a fast-moving patchwork: by June 2026, 38 states and the District of Columbia required districts to ban or restrict phones during the school day, most of them bell to bell. Nor is this only an English-speaking story. UNESCO counted 114 education systems with a national ban by March 2026 — 58% of countries, up from roughly a quarter in mid-2023.

Inside the gates, the evidence splits

The strongest case comes from Norway, where economist Sara Abrahamsson compared middle schools before and after they banned smartphones, using national health and school records. Girls' GPA improved and more of them went on to an academic high school track. GP visits for psychological symptoms among girls fell. Bullying dropped for boys and girls alike, and the gains were biggest for girls from lower-income homes.

England got a flatter picture. The SMART Schools study, published in The Lancet Regional Health – Europe in 2025, surveyed 1,227 pupils across 30 English secondary schools, 20 restrictive and 10 permissive. On wellbeing, anxiety, depression, sleep, behaviour and attainment in English and maths, it found no meaningful difference.

Less contradictory than the headlines suggested. Norway tracked what changed when schools switched, which can show cause; England took a snapshot of schools already differing in a hundred ways. One says a ban can help. The other warns that a policy on paper isn't a change in a child's life.

The number both studies agree on

Restrictive schools did cut phone use during the school day, by around 40 minutes, and social media by around 30. Exactly what a ban is meant to do. Total daily use? Four to six hours — in both kinds of school. The time came off one end of the day and reappeared at the other.

A ban wins back the school day. It doesn't touch the evening. Most of the hours are in the evening.

So do phone bans in schools work? For about six hours

That isn't a sneer. Six hours with the phone out of reach is worth having. But a ban is a fence around one part of the day, and homework, dinner and the hours before bed all sit outside it. That's where the four-to-six-hour total gets built.

Bringing the same idea home

What works at school isn't surveillance or punishment. It's distance: the phone is somewhere else, everyone knows the rule, nobody relitigates it hourly. That part travels.

Monk is a small NFC disc built on the same idea. Leave it on a hallway shelf or the far end of the kitchen. Tap your iPhone on it and the apps you chose go behind a barrier; to open them again you walk back and tap it. Deliberately unglamorous — it puts a body and a staircase between the impulse and the app.

It isn't an unbreakable lock. On iOS no such thing exists, and anyone selling you one is lying. It turns an automatic reach into a decision you make on your feet. It also works for adults, which matters more than most parents want to hear: a rule that applies only to the child reads as punishment; one that applies to everyone reads as how this house works. The first three days are genuinely annoying. After that it becomes furniture.

For the homework version, see a homework routine that survives the phone. If the arguing is the real problem, try phone rules at home without spy apps.

Monk works on iPhone, iOS 16.2 or later. It currently ships within Spain, where it's made.
