A nationwide student cell phone crackdown as some New Jersey school districts start to restrict phone use for students.

The U.S. Department of Education is now calling on all states, districts and schools around the country to implement policies to limit cell phone access for students while at school.

The Education Department noted the negative impacts cell phone use and social media access can have on students mental health.

Alongside this announcement, the GOP released a so-called playbook to give schools guidance on creating those policies.

And if they make recommendations for a full day or schedule based restrictions, as well as designing policies alongside students and parents.

The Playbook tells policy makers to carefully consider exceptions to the rule, like school emergencies or health emergencies.

And they note districts should review rules for storing phones, make it clear who is in charge of enforcing cell phone policies and make sure staff get adequate training.

In New Jersey, a number of districts already have cell phone policies in place, including Cherry Hill Public Schools, which launched a partial cell phone ban this year.
