Teachers reported clear behavioral benefits, though pupil well-being showed little meaningful change.
Implementation challenges eased as the pilot progressed. The introduction of lockable smartphone pouches in secondary schools in Northern Ireland has reduced smartphone use in schools, according to research by King's College London. The study, carried out during the 2025–26 academic year, looked at how the pouches were rolled out and their perceived effects on classroom behavior, academic engagement, participation in school life and well-being.
The pilot study was intended to inform future policy on smartphone restrictions in Northern Ireland and the wider U.K. It used magnetically sealed lockable pouches in which pupils placed their phones at the start of the day and that were unlocked at the end of the day. All secondary schools in Northern Ireland were invited to put themselves forward to be part of the scheme.
Professor Ben Carter, professor of medical statistics at King's College London, said, "Smartphone use in classrooms has become one of the most visible behavioral and safeguarding issues facing U.K. post-primary schools. While 90% now operate some form of restriction, evidence on whether clearer restriction strategies, like a lock-and-store pouch (or brick-phone-only policy), actually change behavior, attainment or well-being has been limited and contested. This evaluation was commissioned to begin filling that gap." "Given the evidence of the wide-ranging benefits to schools, the Department should consider strengthening its current guidance restricting the use of smartphones in schools.
However, it may not be appropriate to mandate a single smartphone approach across all schools. Schools should be allowed to choose from an approved range of strategies that best fit their setting." The evaluation used a mixed-methods design across nine Northern Ireland secondary schools, though only eight engaged fully. Researchers tracked behaviors and attitudes before the pouches were introduced and at follow-up points through the year, using online questionnaires on homework, classroom disruption, PE and extracurricular participation, peer interaction, smartphone use, and measures of anxiety, depression, and smartphone and social media addiction.
Schools also supplied half-termly records of exclusions, detentions, CAMHS referrals, counselor visits and parent visits going back to September 2023. Alongside this, termly focus groups with pupils and staff, plus interviews with school leads, gave a qualitative picture of how the pouches worked in practice, combined with the survey data for a fuller view. The study found that the introduction of the smartphone-free pilot was associated with a reduction in smartphone use.
