 In 2005 the Bill & Melinda Gates Foundation awarded a grant to the district, a significant portion of which went towards Tyee.Beginning in the 2005–06 school year, Tyee ceased to operate as a single comprehensive high school and was split into the three small schools, as noted above.However, it was still recognized by the state as a single school, and thus its graduates received Tyee High School diplomas, and WASL scores were reported only for Tyee as a whole.
