What communication tools does your school use to keep parent's informed? What if school was closed due to weather or a heating/cooling system failure? How would your school let all the parents know so they don't head out to drop their student off? What if there was an emergency at your school? How would parents be notified of a school lockdown or possibly to come and pick up their children? Many parents would be involved. How would your school notify them all at the same time?
