"Student safety is our highest priority. To that end, the Middle School and High School are currently on partial lockdown during which students are able to move within the building, but not leave the building. Students who normally attend KCTC or dual enrollment classes will remain at the high school. The three elementary buildings will conduct indoor recess."

EGR says open campus lunch has been canceled. A police presence remains at the Middle and High School.
