Why do we conduct quarterly fire drills in the schools?

Practice makes perfect.  In all school classrooms, there is an emergency escape plan posted that shows two ways to exit the building from that classroom.  It is required that four times a year teachers and students practice the escape plan, so they know exactly what to do if the fire alarm goes off in a real emergency.  It also gives the teachers a chance to practice emergency procedures that are important in keeping kids safe and accounted for during an emergency.
