Pennsylvania Governor Tom Wolf signed legislation that will allow security personnel to carry firearms on campus.

The bill, sponsored by Sen. Mike Regan, R-Cumberland County, clarifies a law that passed last year to allow sheriffs and deputy sheriffs to serve as school resource officers. It also clarifies that security guards have the authority to carry firearms.

The bill also expands training requirements for armed school officers. It requires that individuals serving as school security guards complete the Basic School Resource Officer Course of Instruction offered by NASRO or an equivalent approved by PCCD. Those currently serving as security guards have six months to complete the training.

It also expands the definition of a school officer to include a county sheriff or deputy sheriff. Wolf’s office says schools were already employing both.
