The Upper St. Clair School District reviewed its security procedures and added layers of security following the tragic school shooting in Newtown, Connecticut.
"Every educator in America was uneasy today," Superintendent Patrick O'Toole said Monday. "We all feel somewhat vulnerable."
The staff in each district building met before class on Monday morning to review safety measures and help the teachers prepare for questions students may ask them.
O'Toole sent out two emails to parents after the massacre on Friday. He said he sent out the information that he would want to know as a parent, including information about how to talk to your children about the incident.
"The tips we send out are the same tips I have to employ as a parent," he said. "Maintaining a normal routine, limiting TV and reinforcing school as a safe place."
