Delaware school district implements new cell phone policy for upcoming school yearNEWARK, Del. (WPVI) -- A new policy will take effect in the upcoming school year for a large school district in Delaware. The Christina School District is prohibiting student cell phone use during instructional time, unless it's clearly authorized by a staff member or permitted under an approved exception. The policy states that acceptable storage includes school-issued storage containers, backpacks, purses or lockers - not pockets or desks. The school district states that this policy aligns with Delaware Senate Bill 106, which requires all schools to establish clear policies on student cell phone use.
