Families have received a letter stating major changes for students of all ages.
The district states that they are in compliance with the state's Phone-Free Schools Act.
Central Unified claims that its primary goal is to foster safe, healthy, and highly focused learning.
Questions remain about academic benefits, but US educators have reported calmer classrooms and strong student engagement.
Central Unified says its elementary school classrooms will have secure lockboxes for storing phones.
The middle and high school campuses will use Yondr pouches that students keep throughout the day, and they will be unlocked when students are dismissed.
Those pouches have already been used in Madera and Fresno Unified schools.
The new phone policy will go into effect on Wednesday, August 12.
