There’s a meaningful difference between three things a school can do about phones: nothing, a written policy, or a physical solution that actually secures the device. The behavior data increasingly shows those three produce very different results.

The gap between “we have a policy” and “the phones are genuinely put away” is where the real improvement lives. Let me walk through what schools are actually measuring, outcome by outcome.

1. Fewer fights — and far less filming of them

The link between phones and school violence isn’t only about distraction; it’s about the audience effect. The ability to film a fight and broadcast it live has, in the words of one 2026 policy review, “gamified school violence, encouraging physical altercations for clout.”⁹ Take away the camera and you take away a real part of the incentive to fight.

The principals who manage this every day see it directly. In a 2025 RAND Corporation survey of roughly 8,000 K-12 principals, about two-thirds reported fewer incidents of students using phones for inappropriate behavior — explicitly including recording fights and filming classmates — after restrictions took hold.² When Los Angeles Unified moved to phone-free campuses, the board member who authored the resolution summarized what schools reported: “fights were down, drug sales were down and kids were reporting a better school day.”⁵

The mechanism matters here, and it’s why securing the phone outperforms a policy. A phone in a pocket under a “no phones” rule can still come out in two seconds to film a hallway scuffle. A phone that’s physically secured cannot. The deterrent only works if the camera is genuinely unavailable.

2. Fewer discipline referrals

This is where the numbers are most striking, and where the contrast between “policy” and “secured” is clearest. North Adams Public Schools in Massachusetts expected modest gains. As assistant superintendent Timothy Callahan put it: “A 10 percent reduction would’ve been a win. We saw a 75 percent drop in referrals in the last quarter of the 2024 school year” compared with the same quarter the prior year — a drop he said was “almost completely attributable to the cellphone ban and the use of pouches.”¹

Note that detail: the ban and the pouches. Not the ban alone. The same pattern shows up across districts that physically secured phones — Medina, New York reported a clear drop in referrals after a bell-to-bell policy,⁷ and Gravette, Arkansas reported substantially fewer phone-related referrals after moving to a zero-tolerance, centrally enforced model. Crucially, the Gravette superintendent noted that enforcement moving from individual teachers to a consistent system was what made the difference⁸ — exactly the gap a physical tool closes.

The largest study to date backs the direction. A 2026 National Bureau of Economic Research analysis of about 4,600 schools — led by scholars at Stanford, Duke, Michigan, and Penn — found that in schools securing phones bell-to-bell, the share of students using phones in class for personal reasons fell from 61 percent to 13 percent, with device activity dropping roughly 30 percent by the third year.³ Fewer phones out means fewer of the conflicts, recordings, and confrontations that generate referrals in the first place.

3. Fewer tardies and less class-skipping

This outcome gets less attention but matters enormously for instructional time. The same North Adams leader who reported the 75 percent referral drop also noted that issues like “students skipping class or detention, or being out of class without permission, have also reduced massively” after the phone ban and pouches went in.¹

There’s a logic to it. The phone is the magnet that pulls a student into a bathroom for twenty minutes, that makes the walk between classes stretch into a hallway hangout, that turns a bathroom pass into a scrolling break. Remove the device from play and the incentive to be anywhere but class drops with it. The most rigorous evidence reinforces this from a different angle: an NBER study of a large Florida district found that securing phones reduced unexcused absences, and that improved attendance accounted for roughly half of the eventual academic gains.⁴ Attendance and presence improve quickly — they’re often the first thing schools notice.

4. Fewer students wandering during class

Ask a principal what the phone changed about the building itself, and you’ll often hear about attention and presence. Dr. Sandy Hattar, principal at Yonkers Middle High School, described students who “always wanted to know what was going on in the bathrooms, in the next room or across the hall instead of being centered in the classroom”⁶ — the restless, half-present churn that a phone feeds. When the phone is secured, that pull disappears.

The before-and-after picture educators describe is consistent: hallways that go quiet during class because students are actually in their seats, and louder at passing time and lunch because students are talking to each other instead of scrolling. In the national data, the share of students reporting personal phone use in class collapsing from 61 percent to 13 percent is this change, measured — students physically and mentally back in the room.³

Policy vs. no policy vs. secured

The throughline in the strongest results — North Adams, Gravette, LAUSD — is the same: the improvement is attributed not to the rule alone but to the rule plus a physical mechanism that secures the phone. A policy sets the expectation. Securing the phone is what makes the expectation real for every student in every room, which is what turns modest, uneven gains into the building-wide drops the data shows.

What the research doesn’t promise

The evidence isn’t uniformly rosy, and you should hear that from us before you build a board presentation on it. The same large 2026 NBER analysis found behavior and academic gains are slow and uneven in the first year.³ The Florida study found suspensions actually rose about 25 percent in the first month of its ban, disproportionately among Black students, before settling back to baseline by year three.⁴

Securing phones is not a magic switch. It’s a structural change that pays off most when implemented consistently and given time, with a rollout that anticipates the early adjustment period. Dramatic single-district results like North Adams’ 75 percent drop are real, but they represent strong implementations — not guaranteed averages. Plan for a bumpy first six weeks and a much calmer second year.

Where Safe Pouch fits

Everything above points to one conclusion: the schools getting results aren’t the ones with the best-worded policy — they’re the ones that physically secured the phone in a way that takes enforcement off individual teachers. That’s precisely what Safe Pouch is built to do.

Safe Pouch secures the phone with a mechanical lock released by a magnet of the correct strength and pattern, so the device is genuinely unavailable during class — not merely “supposed to be away.” Because students keep their own pouch and any teacher can release it at the door in seconds with a Teacher Magnet Unlocker, there’s no centralized unlocking station and no dismissal bottleneck. Enforcement becomes uniform across every classroom rather than depending on which teacher is in the room — closing exactly the consistency gap the RAND data identifies as the reason policy-only approaches erode.²

Lock color sets the release tier, so your campus decides who can open what: the Black Home Lock is parent-released, the Grey School Lock is teacher-released, and the White Admin Lock is administrator-only. And every pouch includes a dedicated cut point anyone can use with no Magnet Unlocker, repaired free under warranty — so staff are never waiting on a device to reach a student in an emergency.
