Gretchen Whitmer Signs Bipartisan Smartphone Ban Into Law As Implementation Challenges Mount Across Michigan Schools

Michigan Governor Gretchen Whitmer signed a comprehensive smartphone ban into law on February 10, 2026, requiring every public and charter K-12 school district in the state to prohibit students from using cell phones during instructional time beginning with the 2026-27 school year.

The bipartisan legislation, introduced as Senate Bill 495 and House Bill 4141, marks one of the most significant education policy changes in recent years. While the law establishes a statewide expectation, individual districts will determine how they implement phone restrictions, creating a patchwork of enforcement approaches across Michigan.

What the Law Requires

The legislation requires Michigan school districts to adopt policies prohibiting the use of cell phones and other wireless communication devices during instructional time, with specific exceptions for emergencies, medical needs, and approved academic use. The law applies only to public and charter schools, leaving private institutions with their own policies.

The legislation was championed by Sen. Dayna Polehanki, D-Livonia, and state Rep. Mark Tisdel, R-Rochester Hills, who worked together to build support across party lines for what both described as a necessary intervention in the ongoing mental health crisis affecting young people.

"We're in the middle of a mental health crisis that is hurting kids," Tisdel said. "Getting cellphones out of the classroom will help protect young, developing brains, and I'm glad we were able to work together to get this done."

The Scale of the Challenge

A new analysis from University of Michigan faculty, published through The Conversation, reveals that the state faces a complex implementation challenge. Researchers collected data on existing cellphone policies in the 2025-26 school year for all 779 publicly funded traditional and charter school districts in Michigan.

At the start of the 2025-26 school year, 94.7 percent of districts already had existing phone mandates in place. Another 2.5 percent of districts required individual schools to set their own policies, and fewer than 3 percent had no stated policy at all.

However, the research team found enormous variation in what rules actually required. Some districts maintained blanket bans during instructional time. Others carved out exceptions for medical or educational purposes, and still others applied different restrictions by grade level.

The new law sets out to standardize these approaches but allows districts flexibility in determining the best way to enforce restrictions.

Enforcement Approaches Vary Widely

The research team classified existing policies based on when and how they were enforced. About half of the district policies provided different rules by grade level. When it came to timing, 50 percent of districts specified bell-to-bell restrictions, meaning students were not permitted to use phones at any point during the school day, including during lunch or passing periods.

The remaining 50 percent mandated schedule-based restrictions, which typically meant phones were prohibited during instructional time but could be used at other times.

When it comes to enforcement methods, the most common approach, adopted by 62 percent of districts, requires students to keep their phones out of sight, such as in their backpacks or pockets. Seventeen percent of districts require students to keep their phones in their lockers throughout the school day.

Roughly 8 percent of districts use a no phones rule that bans phones inside school buildings, while another 8 percent collect phones in each classroom using structured, numbered pocket charts or a designated bin.

Charter and Urban Schools More Restrictive

The research found that policy features were associated with the type and location of districts. Charter and urban districts were substantially more likely than suburban or rural schools to adopt bell-to-bell policies that prohibit phones during the school day.

Roughly 20 percent of charter districts prohibited students from bringing phones to school, while just 2 percent of traditional districts adopted this approach. Traditional districts relied more on lockers at 22 percent and classroom collection at 11 percent.

Twenty-five percent of rural districts, compared to 5 percent of city districts, used the lockers approach for phone enforcement.

Implementation Will Play Out Differently

The Grosse Pointe Public School System already has a policy that closely aligns with the new law, according to Deputy Superintendent Dr. Roy Bishop.

"We believe that our current policy meets the standard of the law, as the law requires schools to create policies restricting, but not completely banning devices during class, allowing exceptions for emergencies, medical needs and specific educational uses," Bishop said.

At Grosse Pointe South High School, phones are currently prohibited with exceptions for passing time, lunch periods, and education purposes under teacher direction.

Elizabeth Bornoty, who has taught at Grosse Pointe South since 1993, has witnessed the rise of cell phones and the consequent need for policy intervention.

"More and more and more, students go grab for it, they hear it vibrate, they want to go look and it's in their pocket," Bornoty said. "They're constantly looking and they're missing what's happening and that long term could have a negative impact."

What Comes Next

The law goes into effect in August 2026 with the start of the 2026-27 school year. Before that, districts will need to update their policies to comply with the new state mandate while defining what instructional time means in their specific context.

The legislation requires districts to provide clear training protocols for staff, define exceptions for health and safety situations, and establish data collection systems capable of tracking whether restrictions produce the outcomes lawmakers intended.

The empirical record on what phone restrictions actually do to academic performance and student wellbeing remains mixed, and Michigan's scale, with nearly 800 districts navigating the same legal requirement from different starting points, will generate evidence that researchers and policymakers in other states will be watching closely.

Whitmer expressed confidence in the legislation's impact, stating in a press release that when students put their phones down, their grades go up. The governor said the policy is intended to help students stay focused and develop healthier relationships with technology.

"These bills will help keep kids focused in the classroom and break their growing dependency on screens and social media. We could all benefit from looking up at the world instead of down at our phones," Whitmer said.

The law also includes specific exemptions for medical or emergency use and does not apply to Michigan's private schools, which maintain their own policies.

As Michigan prepares for implementation, school districts across the state will determine how they enforce phone restrictions, creating a complex landscape of approaches that will ultimately define student phone use in Michigan classrooms.
