FOX19/AP - Lakota Local Schools will train for an active shooter with a simulation that includes hundreds of volunteers.
Lakota Schools and West Chester police and fire personnel plan the exercise 1 p.m. Wednesday at Hopewell Elementary School. Some details are being withheld to help have realistic reactions.
Organizers say the volunteers will help stage "a sense of chaos."
The school's students are out for summer. Residents are urged not to be alarmed by emergency vehicles arriving at the school for the exercise.
Lakota Schools Superintendent Karen Mantia says the collaborative exercise is meant to ensure all the key players are ready for "a worst-case scenario."
A student at nearby Madison Schools opened fire with a handgun in a school cafeteria Feb. 29, injuring four students, none fatally.
