Summary
Tyee High School is a public grades 9–12 school in SeaTac serving 644 students in the Highline School District, an urban area near several other public high schools and specialty programs. The school serves a community with substantial economic need: 75.78% of students qualified for free or reduced-price lunch in 2024–25. Tyee’s student-teacher ratio was 18.5:1, and its current statewide ranking was 356th of 396 schools, in the 10th percentile.
Tyee’s most important challenges involve graduation and staying in school. Its 2024–25 graduation rate was 71.7%, below the district’s 81.8% and Washington’s 82.6%, while its dropout rate was 14.4%, higher than the district’s 10.3% and the state’s 9.8%. These results trail nearby Mount Rainier High School, which reported an 87.5% graduation rate and 6.9% dropout rate, and Foster Senior High School, which reported 89.4% graduation and 5.7% dropout. Academic proficiency is also below state levels in English language arts, math, and science. Science is the weakest current subject at 19.05%, compared with 50.95% statewide.
There are signs of progress, particularly in math, where proficiency rose from 5.38% in 2022–23 to 23.28% in 2025–26. Tyee now exceeds nearby Highline High School, Big Picture School, and Foster in current math results, although it trails Highline in English language arts and science. Smaller programs such as CHOICE Academy are not direct comparisons because they have different sizes, missions, and student populations. Overall, Tyee appears to be improving from a very low baseline, but consistent gains in attendance, credit completion, graduation, English language arts, and science remain priorities.
