SOUTH COVENTRY—Following the tragedy in Newtown, Conn., schools across the nation are more focused than ever before on keeping students safe.

Last week, more than 200 Chester County school administrators and law enforcement officials gathered in the Owen J. Roberts High School auditorium for a county-wide safe schools summit.

The purpose of the summit was to promote safe school environments, share best practices and foster collaboration between school and community law enforcement agencies, according to a press release provided by the Chester County Intermediate Unit, which facilitated the event.
