"It's not just a direct threat like, 'I'm going to hurt you', there are different types of threats and how you have to assess each one differently," says Sharon Schools Superintendent Michael Calla.

Dozens of school officials and mental health experts gathered in Sharon on Tuesday to learn how to do just that.

They've formed a new school safety coalition through the Buhl Healthcare Foundation.

"It's no longer one person looking for that sign. It's no longer just a counselor. It's us as a giant school family," says Corey Yoakam, the foundation's director of school safety and violence prevention.

Under Pennsylvania law, each school in each district will have to have a threat assessment team in place.

Calla says that team includes resource officers, students, and parents along with police.

"They can't give us specific information but they can let us know you want to look into a certain neighborhood or a certain building," he said.

There's also a new 'safe to say something' program in Pennsylvania so kids can report potential threats they see on social media or in school.

The resource officers we talked to monitor students' social media continuously - something Ohio Governor Mike DeWine is calling for in his plan to prevent mass shootings like the one in Dayton.

"There's no expectation of privacy on a social media site," says Hermitage School Resource Officer Anthony Moses. "We have to take advantage of that. That's a great source for us for information and maybe getting into some kid's head."
