Student safety is taken seriously at USD 428. That’s why when you drive by Great Bend High School you will see recently added large yellow and black signs above all of the entrances.“These signs label the doors for emergency responders and also delivery people coming into the building,” explained Daryl Moore, assistant principal. “The signs are large enough to see from the street and they label each of the outside doors.”Moore said that visitors are still asked to use the front doors on Morton Street that are labeled E1.
