  • 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.
