Thirty states have now enacted laws requiring phone-free school environments after comprehensive data showed banning cellphones improves test scores by 14% and reduces bullying incidents by 30%.
The Evidence
A University of Chicago study tracking 500,000 students found that phone-free schools saw a 14% improvement in standardized test scores, with the largest gains among previously low-performing students.
Implementation
Most schools use Yondr pouches that lock phones during school hours. Students keep their phones but cannot access them until the pouch is unlocked at dismissal.
