Welcome to Chinook Middle School

We want to acknowledge and express our outrage around the deep and harmful discrimination, violence, and injustice happening in our country and communities. We want you to know the Chinook Staff stand with our Black community, communities of color, and other marginalized communities demanding to be treated with the full liberty the Constitution declares and the dignity that is innate in all of humanity. You are all important and valued and we truly miss being with you right now.

We want to provide all families, all staff and secondary students opportunities to share feedback, input and ideas on how we can support learning experiences in distance and in-person learning. Please help us better support you by completing the linked survey. The survey will run from March 29 to April 9. Results will help us to plan for this spring and next fall.

Meal Kits

For spring break, April 12 through April 16, meal kits will be offered on Thursday, April 8 from 12:30-1:30 p.m. only. Pick up locations include Chinook and Glacier middle schools and Evergreen and Mount Rainier high schools.

Teacher in class.

More teachers across Highline are using a standards-based approach to grading assignments and giving feedback. We hope to pilot a new standards-based report card soon and want to hear your thoughts. We invite all staff, families and students to attend a virtual focus group to provide feedback on standards-based grading and the new report card.

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