Michigan School Cellphone Policy Study

September 2025 - Current

Summary

Youth Policy Lab has partnered with colleagues at the University of Michigan School of Public Health and the Institute for Firearm Injury Prevention to examine the impact of school cellphone policies in Michigan. This study aims to identify variability in district cellphone policies; understand the barriers to and facilitators of implementation; and estimate their impact on indicators of community violence, including fights in school, school discipline, and police incidents; as well as a range of mental health, wellbeing, and academic outcomes.

While school cellphone restrictions may improve youth outcomes, variation in policy and implementation may make them less effective and equitable. The key questions facing educators and policymakers is not if schools should restrict phone use, but rather what types of restrictions will be most effective for different types of student and school populations, how best to implement these policies, and what unintended impacts may occur.

  • Mounting research indicates associations between smartphone and social media use and disengagement from school, poor mental health, and safety. In response, school districts across the state and country have implemented various policies that regulate student cellphone use. However, little is known about whether such policies improve student outcomes, let alone how the effects vary across student and school contexts, or how challenges associated with policy implementation affect efficacy.

    Michigan is part of a broader movement of states regulating school phone use. A new state law was enacted in February 2026, requiring publicly funded districts to prohibit smartphone use during instructional time starting in the 2026-7 school year. While the law set a statewide baseline, it allowed districts to have a say in how phones are restricted (i.e., kept in lockers, pouches, out of sight, etc), as well as the option to adopt additional measures. The patchwork of district and school policies presents a compelling context to study the impacts of this diverse set of policies, implementation, and district and student populations.

    This project includes:

    • Conducting a digital landscape analysis to identify the status and characteristics of district cellphone policies across the state
    • Facilitating Interviews with district and school administrators and focus groups with parents and students
    • Administering statewide surveys of teachers and administrators
    • Analyzing administrative data to explore a variety of violence, academic, mental health, and well-being outcomes

    This study seeks to achieve the following research aims:

    • Describe variation in district-level cellphone policies as well as facilitators and barriers to implementation of policies that districts use to regulate student cellphone use.
    • Examine which student- and district-level factors predict whether districts adopt cellphone policies as well as the implementation fidelity of the policies.
    • Estimate the impact of school cellphone policies on school and community violence, including variation in effects by race, ethnicity and socioeconomic status
    • Test whether student mental health and academic outcomes mediate the effect of cellphone policies on school and community violence.
    • Test whether implementation fidelity moderates the effect of cellphone policies on school and community violence.

    This projects aims to:

    • Identify the types of restrictions that are most effective for different types of students and school populations as well as the best means to implement these policies.
    • Deliver data-driven insights and recommendations to decision makers in Michigan and elsewhere for cell phone restriction policies that will positively impact students, schools, and communities.

    Our statewide advisory board includes representatives from state departments, professional education and parent associations, advocacy groups, and local school districts. The board provides critical insights and guidance, facilitates connections, and supports dissemination efforts.
