As more states move to ban student cellphones in K‑12 classrooms, analysts caution that the policies do not solve the underlying academic challenges facing schools. In 2026, nearly 40 states have proposed restrictions on cellphone use, and about 20 states plus Washington, D.C. have enacted strict bell‑to‑bell bans for the entire school day.
Expert perspective
Jared Cooney Horvath, author of Digital Delusion and a Harvard‑trained neuroscientist, said decades of research link increased screen time with declines in children’s cognitive development and learning outcomes. He acknowledges that screens can sometimes aid basic skills, but overall they reduce focus and retention in core academic settings.
Lance Izumi, senior director of the Center for Education at the Pacific Research Institute, agrees that cellphone use can interfere with learning but argues it is only a secondary factor. “These cellphone bans are not a silver bullet for what is ailing schools in this country,” Izumi told The Center Square. “The learning decline is a lot deeper than just the fact that kids use cell phones.”
Local examples and mixed results
Some districts report modest gains after restricting phones. At Hoover High School in Fresno, California, English proficiency on the Smarter Balanced assessments rose 21% after a series of policy changes, including a phone‑free classroom rule for the 2023‑24 school year. The San Diego Unified School District also approved a phone‑free policy in 2025.
Superintendent Fabiola Bagula praised the policy, saying, “Limiting the use of phones during the school day creates focused learning environments where students can fully engage with their education and build meaningful connections with their peers.”
State action and federal context
Governor Gavin Newsom signed Assembly Bill 3216, the Phone‑Free School Act, which requires every California school district, charter school, and county office of education to develop policies limiting cellphone usage, effective July 1.
Education Secretary Miguel McMahon noted that K‑12 public education accounts for nearly $1 trillion in taxpayer spending and that achievement gaps are widening despite billions spent on programs. He added that the Trump administration supports giving states more control over education spending.
Broader technology concerns
New York City Mayor Zohran Mamdani announced a moratorium on artificial‑intelligence use in classrooms and a screen‑time policy for the 2026‑27 school year, emphasizing that “children need their teachers and human connection in order to learn and grow.”
Izumi warned that even a nationwide ban would not automatically raise reading and math proficiency, stressing that phone restrictions are only one piece of a larger puzzle.
While studies continue to link excessive social‑media use with anxiety, sleep disturbances, and other mental‑health concerns, the evidence on whether phone bans directly improve test scores remains inconclusive.
