More Florida school districts are limiting cellphones on campus

The big story: The effort to continues to restrict student cellphone use in schools as a way to refocus attention on learning and reduce mental health problems.

The Pinellas and Pasco county school boards are the latest to tighten up their usage policies, each adopting new rules on Tuesday.

At the crux of each plan is an expectation that students will have their phones off or silenced and out of sight during class periods, unless they have teacher permission.
