ORLANDO, Fla. -

Law enforcement officials on Thursday conducted a "large-scale training exercise" at Edgewater High School in Orlando to show agencies how to work together during potential school incidents, including active shooter calls.

Orlando police said prior to the event that the school safety exercise may produce loud noises, but nearby residents should not be concerned.

"A larger than normal police and fire presence will be in the area of the school," police said.

The training exercise began with a "gunman" who burst through the front entrance of the school and fired simulated gunshots.

Orlando police Sgt. Lovetta Quinn-Henry said officers then moved in to secure the situation.

"At that point, they form the active-shooter teams and they enter the school, looking specifically for the person inside the school," said Quinn-Henry.

Police said the training was necessary to demonstrate how several law enforcement agencies could work together in an active-school shooter situation.

"Practice makes perfect," said Quinn-Henry.  "We want to make sure that we're prepared for any unfortunate situation that might happen on a school campus."

Participating agencies included Orlando Police and Fire departments, the Orange County School Board, the Florida Department of Law Enforcement, the Winter Park Police Department, the Kissimmee Police Department and the Orange County Sheriff's Office.

School teachers and administrators, school resource officers and various community partners attended the event.

Officials with Orange County Public Schools said they want parents to know that schools are prepared for every type of situation.

"The safest place for a child to be, if there was an active shooter, is in a lockdown, lay down mode in his or her classroom," said media relations manager Kathy Marsh.
