  • Tim Schlosser Dear Students,

    Welcome to Tyee High School!  We are an intellectually vibrant learning community where students, staff, and the community learn in partnership. We create this learning environment in the context of Highline Public Schools, which promises that every student will be known by name, strength, and need, and that every student will graduate ready for college, career, and citizenship.

    Our diversity is our strength, and our school is defined by strong, caring relationships, joyful and authentic learning experiences, and a shared desire to make a positive impact in the world.  We use real-world learning experiences, challenging curriculum, and powerful teaching to give students the skills, habits, and knowledge they need to succeed in higher education, overcome systemic injustice, and thrive in the world.  We work to ensure that all students graduate on time with wide access to post-high school choices.

    Thank you for being part of our community!  At Tyee High School, your voice counts, and we look forward to getting to know each and every one of you.

  • 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.

  • Share Feedback on Later Start Times

    We are making plans to change to a later start time for high schools. This is in response to feedback from students, families and staff, as well as research that shows teenagers do better in school when they can sleep later.
