Mission CISD requests help addressing the spread of security related rumors

Due to the continuation of social media chatter regarding rumors of threats, Mission CISD had a more visible security presence at Mission High School today. Law enforcement quickly determined no threat was intended. Mission CISD will always err on the side of caution when it comes to the safety of everyone at our schools.

Mission CISD officials are continuing to work closely with law enforcement to address any rumors that appear to be spread through social media channels. We stress there are no credible threats to any Mission CISD campus at this time.

We also ask for the help of all parents. Take this opportunity to speak with your children to reinforce the importance of reporting any information that could impact student safety. Spreading rumors through social media only complicates things and can result in someone being accused of making a false alarm, or worse. Concerns and threats should be reported immediately. Reports can be made to campus administration or through our Stay Alert Hotline, 1-206-406-6485, online through, or email at 

This past week and a half has presented the district and our law enforcement partners with a number of response related challenges. Discussions and planning processes addressing concerns are underway and changes are already taking place. Mission CISD officials will continue this learning and improvement process with each national, state, and regional incident. Main points will always include campus access, surveillance, responses, and staff training. Officials took the opportunity provided by yesterday’s staff development day to provide additional response trainings for all our officers and security guards. Details of less visible security measures will never be discussed publicly as that would actually put our students and staff at risk.

We appreciate your help as we work together to keep our school a safe place for learning.
