At Highline High School, the Unified Physical Education program creates more than just a space for relay races and basketball games. The class is building a community where students of all abilities come together to move their bodies, form friendships, and break down barriers. This is one of many examples of Highline's inclusive education efforts. Students get the support and resources they need in the same spaces rather than in segregated classrooms or gyms. Now in its third year, this program is transforming the school culture.

Join the Family Action Committee  

We are looking for Highline family members to join the Superintendent's Family Action Committee (FAC) for the 2024-2026 school years. The FAC strengthens the connection between families and Highline Public Schools by providing feedback on policies, informing family engagement, and keeping Highline accountable for its strategic plan goals.

Future Ready Fest

This free, drop-in college and career resource fair is designed to guide high school students, especially seniors, through the next steps of their education and career journeys.

Next week, technicians will visit schools and central office locations to update staff devices and passwords. This is part of our efforts to get back online following the cyber incident last month. The process will take place from Monday, October 14, through Friday, October 18.
