Cell phone policies in K-12 are no longer a debate about convenience. A 2025 CDC finding flagged that 17% of high school students reported experiencing cyberbullying via school phones, and that kind of distraction comes on top of the learning disruptions teachers already report. In Cell Phones In Schools, the statistics place academic focus, test outcomes, and even wellbeing in the same scoreboard so you can see what changes when phones are allowed, restricted, or banned.
