California's Phone-Free Schools Act

Supporting Focused Learning, Student Well-Being, and Healthy Connections

Infographic detailing a new cell phone policy for elementary, middle, and high schools, with the tagline 'Learn, Focus, Succeed'.

California’s Phone-Free Schools Act (Assembly Bill 3216) requires school districts to adopt policies limiting or prohibiting student use of smartphones and other mobile communication devices during the school day.

Following input from CVUSD students, families, staff, and community members, the Board of Education adopted an updated Mobile Communication Devices policy for implementation beginning with the 2026–27 school year.

The policy is designed to reduce classroom distractions, support student well-being, encourage positive peer interactions, and create learning environments where all students can remain focused and engaged.

About the Law

Passed in 2024, California’s Phone-Free Schools Act requires school districts to adopt policies limiting or prohibiting student smartphone use during the school day. School districts were required to adopt their policies by July 1, 2026, and review them at least once every five years.

CVUSD’s policy and administrative regulation establish device expectations by grade level, permitted exceptions, emergency procedures, and a progressive framework for addressing violations.

Policy at a Glance

Preschool Through Grade 5

Devices must be turned off or silenced, out of sight, and stored in a backpack or other designated location throughout the school day, including class time, passing periods, breaks, and lunch.

Smartwatches must be powered off or placed in airplane mode and stored. A smartwatch may be worn only when it is fully powered off or in airplane mode and unable to receive calls, messages, or notifications.

Grades 6–8

Devices must be turned off or silenced, out of sight, and stored in a backpack or other designated location throughout the school day, including class time, passing periods, breaks, and lunch.

Devices may be used before school in designated areas, after dismissal, and during certain activities outside the instructional day unless otherwise restricted by school staff.

Grades 9–12

During instructional time, devices must be turned off or silenced and stored out of sight. This expectation applies in classrooms, libraries, labs, other instructional settings, and during restroom breaks taken during class.

Finishing assigned work does not give a student permission to use a device. Devices may be used during passing periods, lunch, and breaks unless otherwise restricted for a specific activity or event.

Exceptions

Device use may be permitted:

  • During an emergency or perceived threat of danger
  • For documented health needs
  • When required by an IEP or Section 504 Plan
  • When explicitly directed by a teacher for an instructional purpose
  • When authorized by a teacher or administrator, subject to reasonable limitations

Privacy Expectations

Devices may not be used in restrooms, locker rooms, or other locations where privacy is expected. Students may not photograph or record another person without that person’s clear and express permission.

During an Emergency

Students must follow staff directions and silence their devices unless otherwise instructed. During lockdowns or shelter-in-place situations, students may not record, livestream, or post information about emergency-response activities.

Families should rely on official District communications during an emergency and should not call school offices unless directed to do so.
