The law changed on 29 June. On that day, 99.8 per cent of primary schools already had a phone policy. What a ban actually buys, what it does not, and the question nobody is inspecting.
On 29 June 2026, Section 36 of the Children's Wellbeing and Schools Act 2026 came into force.
It requires state-funded schools in England to have regard to the Department for Education's guidance on mobile phones, guidance which states that all schools should be mobile phone-free environments by default, and that anything other than that should be by exception only. Exceptions now have to be justified rather than assumed.
From the start of this September, schools are expected to be following it. Ofsted will assess how well they are doing so as part of every inspection.
Note what Ofsted has actually said it will look for. Writing in January, Lee Owston, Ofsted's National Director for Education, set out three things inspectors will do: discuss the policy with leaders, evaluate whether staff and pupils understand the expectations, and determine how consistently the policy is being followed and what impact it is having on pupils' learning, behaviour and wellbeing.
The document is not the test. The implementation is.
That distinction matters more than the legislation does, because in policy terms the legislation changes remarkably little. In April 2025 the Children's Commissioner for England surveyed schools and found that 99.8 per cent of primary schools and 90 per cent of secondary schools already had policies limiting or restricting phone use during the school day.
England has not just banned phones in schools. England has taken a near-universal practice, made it legally enforceable, and asked an inspectorate to check whether it is real.
So the interesting question is no longer whether schools will ban phones. They already had.
The question is what a ban actually delivers, what it does not, and whether the thing it does not deliver is the thing that matters most.
There is a genuine evidence base for restriction, and it deserves to be stated properly rather than waved at.
The most cited British study is Beland and Murphy's work for the LSE's Centre for Economic Performance, covering 91 schools across four English cities. After a ban was introduced, the average pupil gained 6.41 per cent of a standard deviation in test scores at sixteen.
Pupils in the lowest quintile of prior achievement gained 14.23 per cent of a standard deviation. Pupils in the top quintile were neither helped nor harmed.
The authors' reading was that lower-achieving pupils are more easily distracted by the presence of a phone, while high achievers can focus regardless, which makes a ban an unusually cheap way of narrowing a gap.
The strongest international evidence comes from Norway, where Sara Abrahamsson matched survey data on more than 400 middle schools' phone policies to national administrative health and education records.
Following a ban, specialist consultations for psychological symptoms among girls fell by close to 60 per cent, and consultations with a general practitioner by around 29 per cent. Bullying fell for both girls and boys.
Girls' grades improved, and their probability of taking an academic rather than a vocational high school track rose by 8 to 14 percentage points.
The effects were largest for girls from lower socio-economic backgrounds, and they were significant only for girls who had been exposed to the ban for at least two years.
Those are real findings, and anyone arguing against restriction has to answer them.
Now the other side of the ledger.
The first study designed specifically to evaluate England's restrictive school phone policies was SMART Schools, led by Victoria Goodyear at the University of Birmingham and published in The Lancet Regional Health - Europe. It recruited 1,227 pupils aged 12 to 15 across 30 English secondary schools, 20 with restrictive policies and 10 permissive.
Mental wellbeing, measured on the Warwick-Edinburgh scale, averaged 47, with no meaningful difference between the two groups: an adjusted mean difference of minus 0.48, at a p value of 0.62.
Pupils in restrictive schools spent 0.67 fewer hours on their phones and 0.54 fewer hours on social media during the school day. Their overall daily use was not significantly different.
Read those last two sentences together, because they contain the whole problem. The policy worked exactly as designed inside the school gates, and the behaviour it was meant to change reappeared outside them.
A second Birmingham finding, published in February 2026, adds the cost. Schools in England were spending more than 100 hours a week managing mobile phone policies, and that figure held whether the policy was restrictive or permissive.
The same study found no significant difference in pupils' quality of life or mental wellbeing between the two.
The largest study anywhere landed in May 2026, from the National Bureau of Economic Research, covering more than 43,000 American middle and high schools over three years and verifying compliance with GPS data as well as teacher reports.
Lockable pouches substantially reduced phone use. Average effects on test scores were close to zero, with modest gains in high school mathematics and small negative effects in middle schools. There was no detectable effect on attendance, on self-reported classroom attention, or on perceived online bullying.
In the first year, disciplinary incidents rose and pupils' self-reported wellbeing fell. By the third year, the disciplinary spike had faded and wellbeing sat above where it started.
Thomas Dee of Stanford, one of the authors, described the early experience as sobering, and framed the conclusion as one about persistence rather than quick fixes.
A ban is not a policy that works or fails. It is a policy that takes three years to find out.
There is one further finding worth holding onto. Researchers at King's College London reanalysed the OECD's PISA data and found that once gender, social class and school behaviour were controlled for, pupils in schools with phone bans scored lower, not higher.
That does not prove bans harm attainment. It does suggest that schools which ban phones differ from schools which do not in ways most of the headline research has never fully separated out.
Across all of this, one line from Beland and Murphy deserves far more attention than it gets: there are no significant gains in pupil performance if a ban is not widely complied with.
That is the entire policy in a sentence, and it is why Ofsted's framing is the right one.
A ban that is written down and half-enforced produces the enforcement cost without the benefit, which is more than 100 hours a week of adult attention spent on confiscation, appeals and low-level conflict, in exchange for very little.
A ban that is genuinely universal, consistently applied and sustained for years produces the Norwegian result.
The gap between those two outcomes is not policy. It is implementation, and implementation is a behavioural problem, not a legislative one.
Even at its best, the ban addresses a fraction of the exposure.
Ofcom's Children and Parents report, published in May 2026 on the basis of more than 3,400 interviews with children aged 8 to 17 and more than 5,000 with parents and carers, gives the shape of it.
Around a third, 33 per cent, of children who use social media or messaging apps say they feel pressure to be popular all or most of the time, and roughly 70 per cent feel it at least sometimes.
Nearly a quarter, 23 per cent, had experienced nasty or hurtful behaviour in the previous year. Of those, 47 per cent said it happened through social media and 43 per cent said it happened face to face.
Some 37 per cent of children think they spend too much time on screens.
And phone ownership jumps from 56 per cent at age 10 to 83 per cent at age 11, which is to say it arrives at precisely the moment children start secondary school.
Put those figures next to the school day. A ban removes the phone for roughly six hours. It does not touch the evening, the weekend, the school holidays or the bedroom.
And on Ofcom's own numbers, a substantial share of the unkind behaviour children experience is not happening on a screen at all.
Here is the question the legislation invites, and it deserves an honest answer rather than a comfortable one.
The evidence for education is not overwhelming either.
A 2025 meta-analysis of school-based digital literacy interventions pooled ten randomised or quasi-experimental studies covering 6,250 children aged 8 to 18 and found a standardised mean difference of 0.16, rising to 0.34 among primary-age pupils and in smaller trials, and 0.19 where the intervention was explicitly theory-driven.
A meta-analysis of media literacy interventions across 23 studies and 71 effect sizes found a moderate effect on harmful behaviours, minus 0.32 immediately afterwards and minus 0.23 at follow-up, with no significant decay between the two.
School-based resilience interventions, pooled across 38 randomised controlled trials and 15,730 participants, produced a standardised mean difference of 0.17.
Those are modest numbers. They are also, notably, in roughly the same range as the effect of the ban, and they have one property the ban does not.
They survive the walk home.
So the honest answer is not that education is better than a ban. It is that the two are answers to different questions.
A ban is an environmental control: it removes a stimulus from a setting. Education is a behavioural intervention: it changes what a young person does when the stimulus is present and no adult is watching, which describes most of their waking life.
If the answer is education, it has to mean something more specific than a wall display and an assembly.
First, it has to be taught rather than mentioned. Digital literacy in most English schools currently sits thinly spread across personal and social education, computing and citizenship, with the predictable result that topics are covered inconsistently or missed entirely.
A subject that lives in the gaps between subjects belongs to nobody.
Second, it has to be sequenced to development rather than delivered in a single dose. The Ofcom ownership curve tells you exactly where the pressure point is: the year a child turns eleven and moves to secondary school. That is when the device arrives, when the peer group reorganises, and when adult supervision drops away.
The teaching should be heaviest before that transition, not after it.
Third, it has to teach design, not just danger. The Children's Commissioner for England has reported that young people do not want to be cut off; what they want is protection from addictive design and infinite scrolling.
A child who understands why a feed is engineered to be difficult to leave has been given something no confiscated handset can provide, and stops concluding that the problem is their own lack of willpower.
Fourth, it has to teach help-seeking as explicitly as it teaches risk. Almost half of the unkind behaviour Ofcom recorded happened through social media, and the single most protective factor in that situation is a young person who tells someone.
That is a taught behaviour, and it is teachable.
Fifth, it has to be measured. If Ofsted is going to inspect the consistency of a phone policy, the same standard ought to apply to what schools teach about phones.
Otherwise we will inspect the easy thing, because it is the visible thing.
And sixth, it has to be resourced out of the money the ban is already spending. More than 100 hours a week of staff time is currently going into managing devices.
A fraction of that, redirected into structured teaching delivered by people who know the subject, would fund the alternative without a new budget line.
The ban is not the mistake.
Given the Norwegian evidence on bullying and on girls from low-income homes, and given that consistently applied restriction appears to help the pupils who are furthest behind, an unenforced free-for-all was never defensible.
The mistake would be believing the work is now done.
England has legislated for the six hours it controls, and said very little about the eighteen it does not. Ofsted will now inspect whether the phones are away. Nobody is inspecting whether children have been taught anything about what happens when they come back out.
This is the same distinction I drew in Age Appropriate vs Resilience Appropriate, between removing a risk from a room and preparing a young person for a world in which the risk is permanent.
A ban tells a young person what they cannot do inside a building. Education gives them the judgement to decide for themselves everywhere else, which is where they spend most of their lives, and all of the rest of them.
This is the argument at the centre of my first book, Rebuilding the Village, out in early 2027: that the structures which used to teach children judgement have thinned, and that no amount of legislation replaces them.
