Policies that restrict students' cell phone use during the school day have become ubiquitous in U.S. schools. The authors of this report used data from a nationally representative survey of students to examine what types of cell phone policies students are subject to at different grade levels. They also investigated associations between school cell phone policies and students' self-reported cell phone checking during the school day.

Policies that restrict students' cell phone use during the school day have become ubiquitous in U.S. schools. Public opinion polls show that although educators strongly favor such policies, citing a variety of perceived benefits to students' learning, attention, and mental health, youth are much more skeptical. Prior work on this topic has largely ignored the fact that not all schools' cell phone policies are the same. The absence of detailed data on the variance in school cell phone policies has constrained knowledge of whether specific policy features affect students' cell phone use at school.

The authors of this report used data from a nationally representative survey of middle and high school students to examine the extent to which school cell phone policy strictness shapes student cell phone use. They first provide an overview of five common types of school cell phone policies in place in U.S. public schools. They then investigate the associations between school cell phone policy contexts and students' self-reported cell phone checking. They also examine the tactics that students take to evade these policies and to what extent enforcement matters for students' cell phone checking.

Key Takeaways

  • The number of times that students report checking their cell phones during their classes each day is related to differences in the restrictiveness of their schools' cell phone policies.
  • According to student reports, more-restrictive cell phone policies mitigate but do not fully eliminate students' cell phone checking.
  • Even in the most-restrictive policy environments, one-half of students reported checking their cell phones during their classes at least once during the school day and roughly one-sixth reported checking them frequently (more than five times per day).
  • Students in schools with more-restrictive cell phone policies are more likely to say that their teachers are strict or very strict about enforcing cell phone rules. However, even in the most-restrictive policy environments, students report checking their cell phones less when they perceive that there is stricter enforcement.

Recommendations

  • More data are needed to unpack the enforcement of and compliance with school cell phone policies (e.g., how many students are getting caught violating the policy, what are the consequences when they do, are the same students repeat offenders).
  • More investigation is needed to determine the extent to which types of school cell phone policies are associated with a variety of student outcomes beyond cell phone use — such as student achievement, student engagement, peer-to-peer social interactions, and peer-to-teacher relationships.
