Safety is our number one priority. Two elementary schools in the Bellevue School District recently reported cyber kidnapping incidents. Cyber kidnapping is a new scam where families are tricked into paying money by making them think a loved one is in danger. Although no cases have been reported in Highline, we are sharing information to help our families stay vigilant and safe.

Our Business Services staff will brief the school board on our financial picture for the 2024-25 school year at a work session on Wednesday, March 6, from 4:30 to 5:45 p.m. The work session is open to the public. The community is invited to attend or watch online.

We use technology to make learning better. We think about how and why we use screens in school, focusing on active screen time, where students use their brain and body vs. just passive screen time. Tools like Chromebooks and iPads help everyone learn in their own way. 

Our Vision

Together we create and sustain a culture of achievement where all students excel!
