Emergency Notifications

As a school district, we strive to provide the most complete and in-time information possible during emergency and inclement weather situations. Below is a complete list of methods we use for communicating messages to staff and families.

Inclement Weather: Messages posted to District website, Facebook page, local news stations, and text alerts to staff and families. Be sure to read our Inclement Weather Message, which outlines our cancellation and delay process.

Illness-related Closures: In this new era of COVID, there may be instances were a school or schools may need to close. This information will be communicated through robo-call, text alert, and email through ParentSquare, the District website, and our District's Facebook page. 

Emergency Situations (Secure and Teach, Lock Down, Shelter in Place, Evacuation and Reunification): Messages posted to District website, Facebook and Twitter, text alert sent to staff and families. In the event that more information needs to be sent, a robo-call will be used with a recorded message which can be accessed through ParentSquare.
