Birmingham Public Schools' bell-to-bell phone ban will take effect Monday, Aug. 31, after the board declined to reconsider the policy at its Tuesday, Aug. 25 meeting despite opposition organized by more than 130 parents in a Facebook group, according to FOX 2 Detroit.

Six parents spoke against the ban and four spoke in favor during public comment at the meeting, held at the Birmingham Education & Administration Center in Beverly Hills, FOX 2 Detroit reported. The board did not reverse or modify the policy it approved 4-1 on July 7.

The ban stands.

The policy prohibits students in all grades, K-12, from using cellphones or any personal device from the first bell to the last bell of the school day. That includes passing periods and lunch. The policy goes beyond Michigan's state law, which bans devices during instructional time only, according to CBS News Detroit.

Parent Luz Lawton, who helped organize the Facebook group, told FOX 2 Detroit before the meeting that the district had initially told high school parents in June that their students could keep phones during passing time and lunch. That changed without warning.

"I don't feel that the work is being done to show how they're going to implement it, what's going to be required if a student has a phone, what are the repercussions," Lawton said. "I don't have any of that information."

Lawton stressed she supports banning phones during class. Her concern centers on lunch and passing time, when students may need to reach parents about schedule changes or rides.

Not all parents opposed the policy. Melissa Holland, who spoke at the Tuesday, Aug. 25 meeting, told FOX 2 Detroit the strict approach eliminates gray areas and encourages students to socialize face-to-face during breaks.

Another parent, Jennifer Brodjeski, raised a different concern. Her daughter, a senior, has used a personal iPad alongside her school-issued laptop since sophomore year and keeps all her notes backed up to the cloud. Brodjeski argued the device should be allowed for her daughter's final year.

The district acknowledged the split in a statement to CBS News Detroit, saying it recognizes differing viewpoints and knows the policy will be an adjustment for families. Superintendent Embekka Roberson told CBS the ban takes effect on the first day of school.

Deputy Superintendent Cory Heitsch introduced the bell-to-bell language at the July 7 board meeting, where the first reading was waived. Board members Lori Ajlouny, Omar Odeh, Luke Joseph and Nicole Spencer voted yes. Jennifer Rass cast the lone no vote. Amy Hochkammer and Colleen Zammit were absent, according to board minutes.

The district has not publicly released details on enforcement, including what happens if a student is caught with a phone or how confiscation will work. That gap remains unresolved with school starting Monday, Aug. 31.
