Abstract: The widespread use of mobile devices among adolescents has led many schools and governments to consider or implement restrictions on their usage. This study provides a comprehensive analysis of the effects of school cellphone policies on student outcomes, focusing primarily on student well-being and classroom dynamics. Using detailed microdata from the 2022 Programme for International Student Assessment (PISA) across 81 countries, the study finds that stricter cellphone policies are associated with significant reductions in classroom distractions and lower levels of student-reported anxiety related to mobile-device use, even under mild enforcement conditions. Moreover, when bans are effectively enforced, measurable improvements in standardized test scores emerge, providing clarity to previously inconclusive findings in the literature. Subgroup analyses reveal limited heterogeneity, although private school students experience greater anxiety reductions. Policy recommendations emphasize the critical role of enforcement, the importance of targeted approaches tailored to school context and socioeconomic differences, and the necessity of continuous policy evaluation and adaptation.
