About Our School

  • Welcome to Centennial Middle School, home of the Patriots! We are located just north of the City of Snohomish and we are a part of the Snohomish School District. Our school is a safe, student-centered community built on integrity and respect and is a place where the pursuit of academic excellence is the standard. Our administrators, teachers, and staff work hard to see to our students gain the skills and learn the concepts they need to succeed in life. Our school has about 750 7th and 8th graders who come to us from our feeder elementaries - Cascade View Elementary, Dutch Hill Elementary, Emerson Elementary, Machias Elementary and Riverview Elementary. After 8th grade, our students attend Snohomish High School.

    We thank you for visiting our website and hope that you enjoy visiting our campus from a distance!

    At Centennial Middle School we provide opportunities for students to gain new knowledge, by traditional instruction (lecture and texts), inquiry (discovery and experience), and by building and creating (construction). The latter two are the most powerful, by far. We promote and use instruction that supports experiential and constructivist learning and we believe in high standards with frequent, meaningful assessments that inform instruction and learning. The result, facilitated by quality instruction, is authentic, meaningful learning and an education that helps students develop habits of lifelong learning.

    The Centennial staff promotes a school culture that:

    • Has a positive climate where kids are connected
    • Includes community building with academics and couples academics with other tasks, skills and discussions
    • Has high standards
    • Is cooperative and collegial
    • Practices reflection
    • Uses numerous resources
    • Adopts a spirit of inquiry
    • Has an atmosphere and climate that promotes a free flow of ideas and
    • Provides a curriculum rich in social and cultural contexts

    Superior instruction and a school culture which promotes meaningful relationship increases academic achievement, supports social growth, improves attendance, lowers drop-out rates and discipline issues, increases student and family  involvement, and ultimately results in greater teacher, student, parent, and community satisfaction. We thank you for sending your student to Centennial and welcome you as a member of our mutual school community.

    According to the OSPI Report Card, there were 751 students enrolled at Centennial Middle School during the 2021-2022 school year.
