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.

Seeking Student Voice

We want to hear and learn from students. Does your student have something to share about their experience as a student in Highline? We are seeking students to share their experiences at the 2021 Highline Equity Symposium on Tuesday, August 24. 

Happy School Nurse Day

This week we’re celebrating our school nurses! This year especially we want to shout from the rooftop: THANK YOU! School nurses serve our students in managing complex conditions, identifying mental health issues, leveling the field with regard to health disparities, and now, testing, tracking cases and vaccinating staff.

Next fall, we plan to reopen schools for in-person instruction five full days a week for students in Pre-K through grade 12, as long as public health authorities continue to support in-person learning. 

As recommended by the CDC and Washington State Department of Health, we will require three-foot distancing, face masks and other safety measures. Families will be able to choose a remote option.
