    Vision / Mission
    Home of the Thunderbirds!

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


    Chinook students leave middle school with an awareness of themselves and the essential skills and knowledge necessary for success in high school. They are community-minded citizens who are excited about their future and confident about their options for college and career. They are empowered to access opportunities and overcome those they may be denied.


    The mission of Chinook Middle School is to create and sustain a culture of achievement where all students excel.


    • Personalization: We know our students well as learners and as individuals. All students are known by name, strength and need, and we use this information to differentiate instruction for each student’s success. Their growth and achievement is further supported by our house model and strong advisory program.
    • High Expectations and Urgency: We believe that all students can achieve at high levels and can engage in positive learning behaviors at all times. We clearly communicate a warm-demander’s stance - “I care for you and therefore, expect the very best from you.”
    • Excellent Instruction: We expect our students to think critically, and we design engaging learning experiences that guarantee students use their minds well. Our classrooms are characterized by students actively engaging in authentic content and teachers effectively facilitating and responding to student learning.
    • Tone of Decency and Trust: We value our relationships and treat each other with fairness, kindness, and generosity. We are proud of our diversity and see it as our strength. Students and staff have a sense of belonging and safety and feel confident to use their unique voices and take intellectual risks.

    Dear Chinook Families,

    I truly believe I have one of the greatest jobs in the world and am so proud to be able to serve as the principal at Chinook Middle School.

    Our team of teachers and support staff are some of the most outstanding individuals I have ever worked with and I commend each and every one of them for their service and commitment to our students’ education.

    At Chinook we are committed to building and sustaining a culture of achievement where all students excel. We do this through our core beliefs of Personalization, High Expectations and Urgency, Excellent Instruction and building a Tone of Decency and Trust.

    Chinook will start the year with a unique three-day schedule that is focused on strong transitions through community building, communicating guidelines and expectations for the year, and building a strong start for Advisory.

    We have developed an Annual Action Plan that represents the high expectations we share and the unwavering belief we have in our students. Our 2017 goals are aligned to our District Strategic Plan:
    • 95% of our 9th grade students will be at grade level standard in algebra. This means we will increase access with more course offerings for 8th grade algebra and 7th grade pre-algebra classes next year.
    • 95% of our students will graduate prepared to choose their future. This means we will provide excellent instruction using standards based instruction and grading practices in all classrooms. Increased reading expectations in the areas of volume and stamina for all students is critical to this goal and an area of focus in the 2017 – 2018 school year.
    • Every student is expected to read every night for thirty or more minutes. We know that reading is essential to the success in school in all content areas.
    • Reduce suspension rates to zero by 2018 (except when critical for student and staff safety). This means our guidelines and expectations will be clearly communicated to students and families. Staff will provide consistency with common messages across classrooms. And we will use restorative practices when addressing and solving problems at school.

    We continue to work to improve our literacy and math progress, which includes a blended learning approach with technology programs to enhance our students’ access to math and literacy content.

    On September 5th we will host an Open House between 12:00 p.m. and 4:00 p.m. This day provides time for students and their families to visit our campus, meet teachers, counselors, principals, and support staff. You will be able to purchase your ASB cards, PE clothes, and check out your Chromebook for the school year.

    Chinook Middle School continues to build a safe community of learners through the establishment of clear guidelines and expectations and Positive Behavior Intervention Supports (PBIS). Our Guidelines are driven by Chinook Values to SOAR. Thunderbirds Soar to Success through Safety, Organization, Achieving and Respect. In addition we offer increased personalization through a teaming, or house model, in which four core teachers will work closely together to serve 100 to 130 students with Advisory at the heart of our school model.

    Students will participate in an advisory three times a week. Each Advisory is small with one advisor assigned to 18 or 20 students max. Our Advisory and Houses will use a relentless approach to ensure every student is on track and progressing in school. We encourage all parents and families to get to know your child’s Advisor. This will be your first point of contact to acknowledge successes, ask questions, and share concerns. Advisors are expected to maintain regular contact and be available to parents and families.

    Community Partnerships are important to our work. We look forward to continuing our partnership with Mac and Zoe Strong TEAM WORKS foundation. TEAM-WORKS mission is to provide holistic, compassionate and culturally responsive mentoring to empower disadvantaged youth and their families to develop strong minds, strong bodies, and strong character. TEAM WORKS will continue to run through our Health classes this year.

    Finally, we want our students and families to learn about our rich after-school programs. All students are welcome to join sports. We offer a large choice over four seasons. Clubs and extended learning opportunities are also available and include: Science Olympiad, Robotics, Techbridge, and Garden Club. After-school tutoring will also be available. If this is something you want to make sure your student can access, please don’t hesitate to contact us.

    We are definitely looking forward to an exciting year at Chinook Middle School, Home of the Thunderbirds!

    Please see our Performance Report for more information about Chinook Middle School (coming soon).

  • Why Run a Levy? Hear From a Student

    There is a gap between what the state funds and the education Highline provides to students. Levy funds make up the difference. Mount Rainier High School student Cassidy Huff explains why we have the bond measure on the ballot and what it will fund.
