AB 1644 directs every California school district, county board of education, and charter school governing body to adopt, by July 1, 2027, a policy that prohibits pupils from using smartphones while on campus or under school supervision, with narrowly drawn exceptions (emergencies, teacher permission, medical necessity, or IEP requirements). The bill requires stakeholder input, five‑year policy updates, and allows the State Department of Education to request and audit adopted policies.
The measure also states legislative intent to enact a statewide bell‑to‑bell restriction and includes a provision that the policy must not authorize monitoring or collection of pupils’ online activities. Because it imposes duties on local educational agencies, the bill triggers the state‑mandated local program regime and ties reimbursement to the Commission on State Mandates’ determination.
At a Glance
What It Does
Requires local education agencies to develop and adopt a policy prohibiting pupils’ smartphone use at school or while under school supervision by July 1, 2027, with mandated stakeholder participation and five‑year updates. The law expressly permits only limited exceptions and bars policies that authorize monitoring or collection of pupils’ online activities.
Who It Affects
Public school districts, county offices of education, and charter schools statewide; teachers and administrators who will implement and enforce the policies; the State Department of Education which may audit compliance; and pupils and families subject to the new prohibition and exceptions.
Why It Matters
This shifts California from permissive, locally varied smartphone rules toward a uniform, statewide ban during school hours, creating new compliance obligations for LEAs and raising operational, equity, and privacy questions for educators and policy teams.

What This Bill Actually Does
AB 1644 replaces the prior requirement that local education agencies merely limit or optionally prohibit smartphone use with an affirmative duty to adopt a prohibition policy by July 1, 2027. The bill pushes districts and charter schools to design policies whose stated goal is a bell‑to‑bell ban—effectively barring pupil smartphone use for the entire school day while on site or under staff supervision.
That requirement must be revisited and updated at least every five years, and districts must involve significant stakeholder participation during development so the rules reflect local needs.
Even though the overarching rule is a ban, the bill carves out four narrow exceptions: (1) emergency situations or threats (unless already covered in a comprehensive school safety plan); (2) express permission from a teacher or administrator, subject to reasonable limits; (3) a licensed physician’s determination that a student needs a smartphone for health or well‑being; and (4) situations where possession or use is required by a pupil’s individualized education program. These exceptions are procedural and require local policy drafters to build processes for medical and IEP accommodations and for teachers to grant limited, case‑by‑case permissions.The statute also places two checks on enforcement practices.
First, it expressly prohibits any policy that would authorize monitoring, collecting, or otherwise accessing information about a pupil’s online activities. Second, it authorizes the State Department of Education to request copies of adopted policies and, where indicated, to monitor or audit LEAs for compliance.
The bill therefore creates a reporting and oversight pathway that could standardize implementation across districts.Finally, AB 1644 includes the procedural language necessary to treat the measure as a state‑mandated local program: if the Commission on State Mandates determines the bill imposes costs, reimbursement will follow the normal statutory procedures. The bill also contains an explicit legislative intent statement signaling future action to impose a full bell‑to‑bell restriction statewide, which frames current duties as preparatory for stricter rules to come.
The Five Things You Need to Know
Deadline: LEAs must adopt a smartphone prohibition policy by July 1, 2027, and update it at least every five years.
Exceptions: The ban does not apply during emergencies, when a teacher/administrator grants permission, when a physician certifies need, or when an IEP requires phone use.
Oversight: The State Department of Education may request policies and conduct monitoring or audits to check compliance.
Privacy guardrail: The statute explicitly forbids policies that authorize monitoring or collecting pupils’ online activity.
Mandate funding: The bill triggers the state‑mandated local program process; reimbursement depends on a Commission on State Mandates finding.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Transition language and temporary operative policy framework
This amendment keeps the existing requirement that districts develop smartphone policies but makes the current, more permissive text inoperative as of July 1, 2027 and schedules repeal on January 1, 2028. The change functions as a transition: it preserves stakeholder engagement and evidence‑based policy language in the near term while clearing the way for the stricter obligation added in the next section.
Mandatory prohibition policy and oversight
This is the core operative provision. It requires every district, county board, and charter governing body to adopt a policy that prohibits pupils’ smartphone use while on campus or under staff supervision, states the goal of creating a bell‑to‑bell ban, requires stakeholder participation, allows enforcement mechanisms to restrict access, and lists the same four exceptions (emergency, teacher/admin permission, medical necessity, IEP). It adds that policies must be produced to the Department upon request and that the Department may monitor or audit compliance—creating a pathway for statewide enforcement and standardization.
Department access and audit authority
Subsection (c) specifically authorizes the State Department of Education to request copies of locally adopted policies and to perform monitoring or auditing to ensure compliance. Practically, that creates a compliance reporting obligation and exposes LEAs to administrative review; districts should expect to be able to produce policy documents and supporting materials if the department seeks them.
Privacy prohibition
Both the amended and new sections contain a clause that disallows policies authorizing monitoring, collecting, or otherwise accessing any information related to a pupil’s online activities. This limits enforcement tools that rely on digital surveillance and requires LEAs to design non‑intrusive compliance mechanisms.
Reimbursement mechanics for mandated costs
The bill instructs that, if the Commission on State Mandates finds the act creates state‑mandated costs for local agencies, reimbursement will proceed under the established statutory process. That places the fiscal question into the standard claims process rather than providing an upfront appropriation, leaving reimbursement timing and sufficiency uncertain until the Commission rules.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Classroom teachers and administrators — they gain a statutory tool to reduce in‑class distractions and a common policy structure to support consistent enforcement across schools.
- Students focused on learning — reduced phone access during instructional time aims to improve attention, academic engagement, and potentially mental well‑being for pupils vulnerable to distraction.
- Parents seeking predictability — families preferring phone‑free schooldays get a uniform legal baseline and clearer expectations across districts.
- Mental health and child development advocates — the bill aligns with policy positions that reduced on‑screen exposure during class supports learning and wellness.
Who Bears the Cost
- School districts and charter school governing bodies — they must draft stakeholder‑informed policies, implement enforcement systems, and respond to Department audits, incurring staff time and potentially new operational expenses.
- Teachers and school staff — enforcement and permission decisions increase administrative workload and may shift classroom management responsibilities onto already stretched educators.
- State Department of Education — the Department gains a monitoring role that will require staff time and resources to process policy requests and conduct audits.
- Students requiring accommodations and their families — while exceptions exist, navigating medical or IEP processes to secure legitimate phone access may require documentation and administrative steps that can be burdensome.
Key Issues
The Core Tension
The central dilemma is between creating a uniform, distraction‑reducing school environment through a strict bell‑to‑bell smartphone ban and preserving equitable, flexible access to devices that some students need for health, learning accommodations, or family communication—while also avoiding an unfunded compliance burden on local education agencies.
The bill's effectiveness depends heavily on how districts translate a high‑level prohibition into operational rules. Policymakers must choose between low‑tech enforcement (teacher collection of devices, storage systems) and more complex technical solutions (device lockers, network controls), each with cost, labor, and equity implications.
The statute bars monitoring of pupils’ online activity, which narrows enforcement options and steers districts toward physical or procedural controls; those controls can be logistically difficult in large or underfunded schools.
Equity problems are real and unresolved. Some pupils rely on smartphones for translation, internet access outside of home, or family communications; although the bill provides carve‑outs for medical and IEP needs, it leaves discretionary teacher permission as the primary mechanism for ad‑hoc accommodation—potentially creating inconsistent access and stigma.
The reimbursement path through the Commission on State Mandates means districts may bear up‑front costs while waiting for a claims determination; absent proactive funding, resource‑constrained LEAs will face the choice of diverting funds or rolling out minimal compliance plans that undermine the law’s learning objectives.
