Do phone bans work? Here’s what research says about phones, academic performance and GCSE results, including evidence from UK schools.

For parents the question is ‘do phone bans work?’. If a school removes your child’s smartphone for the entire school day will they concentrate better, learn more and ultimately get better GCSE results?

While the research is encouraging, it is a lot more nuanced than a simple yes or no. Evidence from England shows restricting mobile phones can improve academic performance, with the strongest benefits for pupils who are already struggling academically. Research has also found an overall negative relationship between mobile phone use and educational outcomes.

On the other hand a phone ban isn’t magic. GCSE results depend on a huge range of things including the quality of the teaching, the child’s attendance, socioeconomic circumstances, previous achievements, motivation, additional needs and support at home.

Do Mobile Phone Bans Improve Academic Performance?

So what does the research really tell us about phones and academic performance? And what should parents make of the move towards phone-free schools? Here’s what we know.

The short answer: Do phone bans work?

We’ve taken care not to over-claim what the research proves. While there is evidence that a school phone ban can improve academic performance, it is not a guaranteed way to  boost GCSE grades.

One of the most important studies looked at data from English secondary schools. It discovered pupil performance in important exams improved after schools introduced mobile phone bans. But the improvement mostly affected children who had been among the lowest achievers before the ban. The researchers found an up-tick of around 14% of a standard deviation for pupils in the lowest achievement group, while the highest-achieving children weren’t really affected.

Overall the results suggest the benefit of removing phones isn’t so much about helping high-performing children get even better grades. It seems to help some children who find it particularly difficult to focus and pay attention.

What does ‘14% of a standard deviation’ mean?

14% of a standard deviation is a small effect, noticeable statistically but modest compared with the normal differences between a group of people. Basically, the lower-performing pupils did a little bit better but the difference wasn’t huge:

  • 0% = no difference
  • 14% = small difference
  • 50% = big difference
  • 100% = all the difference.

What does the research say about phones and academic performance?

There are two questions to answer here. First, does having or using a mobile phone affect academic performance? Second, does removing access to phones improve academic performance?

A large body of research has investigated the relationship between smartphone use and achievement at school. One 2018 meta-analysis included research between 2008 and 2017. It found an overall small negative relationship between mobile phone use at school and educational outcomes. But this doesn’t mean every child who uses a smartphone will do worse at school.

It looks like problematic mobile phone use is associated with poorer results at school, but it’s important to know the research was observational. It can identify a relationship between phone use and achievement, but it can’t prove phone use at school causes lower achievement. For example, a child who is struggling at school might also be more likely to spend time on their phone. In this case the phone and lower achievement are associated, but the phone isn’t the only cause.

The landmark English study: What happened when schools banned phones?

The study mentioned in discussions about school phone bans most often is Ill Communication: Technology, Distraction & Student Performance, by Louis-Philippe Beland and Richard Murphy. Published in Labour Economics in 2016, it examined secondary schools in four English cities: Birmingham, London, Leicester and Manchester, still the key English study of school phone bans and pupil achievement.

The researchers combined information about school mobile phone policies with data from England’s National Pupil Database. Rather than just comparing pupils who used phones with pupils who didn’t, they looked at what happened to student performance before and after schools introduced bans. This makes the study particularly useful.

The results showed test performance improved after schools banned mobile phones. But the most striking finding was who benefited most. Pupils in the lowest achievement group saw an improvement of 14.23% of a standard deviation, small but noticeable. But the researchers found no significant effect for pupils in the highest achievement group.

One possible explanation is that pupils who already have strong concentration and self-regulation skills might be better at ignoring their phone, even if they have it on them. For a pupil who finds distraction difficult to resist, a smartphone can create a much bigger problem. They don’t need to look at a notification, message or social media post for the interruption to compete with a teacher. The notification sound is enough. So removing the temptation altogether might make a bigger difference to some pupils than others.

Could a phone ban improve GCSE results specifically?

This is where it is really important to be precise. The research says banning phones can improve test performance, including high-stakes exams like GCSEs. But it doesn’t mean a particular child will get a better GCSE grade because their school introduces a phone ban.

A school with a phone-free policy might experience improved behaviour, attendance, teaching consistency, pastoral support and academic intervention for other reasons, making it difficult to pin down exactly how much of a change in GCSE performance can be attributed directly to the phone policy. The English evidence is significant here because the researchers tried to account for differences between pupils and schools, looking into changes associated with the timing of the phone policy’s introduction. At the end of the day the results were still positive after a set of robust checks. For parents the sensible conclusion is: A phone ban can create better learning. There is evidence that this can translate into improved academic performance. But it is just one part of the education environment, not an exam results guarantee.

Do phone bans improve behaviour as well as grades?

Basically, academic performance is only one measure of a successful school. Phones can also play a part in disrupting all sorts of behaviour. They can distract attention, interrupt classes, limit face-to-face socialising, damage pupil-teacher relationships, enable online bullying and create safeguarding issues. Removing the potential for all this can make school life happier for children.

What does the research not tell us?

This is maybe the most important part of the discussion. The evidence does not show that:

  • Every pupil will get better GCSE grades after a phone ban
  • Phones are the only cause of poor academic performance
  • Banning phones solves every behaviour problem
  • Smartphones have no educational value
  • Every school should use exactly the same enforcement system.

It also doesn’t mean the technology itself is bad for education. Digital technology can be an extremely valuable education tool when it is used deliberately and controlled properly. The issue is the difference betweenusing thetechnology for learning and letting it compete for a child’s attention.

How will the school measure success?

This is an interesting question for parents. It should be possible for the school to look for changes in a few key areas: 

  • Levels of classroom disruption
  • Number of behaviour incidents
  • Pupil attendance
  • Pupil engagement
  • Teacher workload
  • Safeguarding concerns
  • Pupil wellbeing
  • Academic outcomes.

Monitoring these outcomes will help a school understand whether the policy is achieving its goal. Because schools are supposed to monitor the policy and review it regularly, they will be able to provide the answers parents need.

So, do phone bans work?

The research gives parents a reasonably strong reason to believe restricting access to mobile phones  supports better academic performance. Removing this powerful source of distraction can create better conditions for learning and, for some pupils, this translates into measurable wins. For parents, the question is whether their children need a constant source of digital stimulation while they are supposed to be learning. The evidence suggests removing phone distraction can help many pupils. Generally, if a phone-free school day gives a child more opportunity to concentrate, participate, talk to their friends face-to-face and engage with their lessons, any improvement in their GCSEs is icing on the cake.

The bottom line for parents

There is no single policy to transform GCSE results overnight. But the research increasingly supports the simple idea that children learn best when they can give their attention to learning. A phone ban is not really about taking something away from children. Done well, it’s about giving them something valuable back: their attention.

FAQs

Here are some quick answers to some of the most frequently asked questions about the benefits of mobile phone usage control in schools.

Evidence shows school phone bans can improve pupils’ academic performance, including performance in high-stakes exams like GCSEs. One major English study found an average improvement of around 0.07 standard deviations after schools introduced phone bans. But this doesn’t mean every pupil will achieve higher GCSE grades.

Research suggests lower-achieving pupils might benefit most. In the Beland and Murphy study, pupils in the lowest achievement group saw a small but noticeable improvement of 14.23% of a standard deviation, while the highest-achieving pupils showed no significant effect.

As a general rule research shows a small negative relationship between mobile phone use and educational outcomes. But a lot of the research points to an association, not proof that phone use is directly responsible for lower grades.

In many cases, yes. A phone-free school doesn’t always mean pupils leave their phones at home. Schools can let children bring phones for journeys to and from school but they’re securely stored and inaccessible throughout the school day. The exact arrangement depends on the school’s policy.

The Department for Education’s revised mobile phone guidance became law in late June 2026 and schools began following it from 1st September 2026. It expects schools to prohibit mobile phone use throughout the school day, including lessons, breaktimes, lunchtimes and the times between lessons, with appropriate exceptions and adaptations.
