Summary:
ZIP code 99022 has two high schools serving grades 8–12: Medical Lake High School, a conventional grades 9–12 school with 506 students, and Martin Hall Detention Center, a specialized grades 8–12 program with eight students. The schools serve very different purposes, so the most meaningful information for families is concentrated on Medical Lake High School.
Medical Lake High School stands out for its 96.3% graduation rate, matching the Medical Lake School District and exceeding Washington’s 82.6% rate. Its recent ranking places it above the statewide midpoint, at the 72nd percentile with a four-star rating in 2025–2026. The school also exceeded state results in English Language Arts and science. ELA proficiency was 60.95%, compared with 52.81% statewide, while science proficiency was 61.82%, compared with 50.95% statewide. These results, together with the strong graduation rate, indicate a generally successful school with solid academic outcomes.
The main area of concern is math. Only 38.1% of students reached proficiency in 2025–2026, below both the district’s 46.87% and the state’s 43.11%. ELA also declined from 75.7% the prior year, although the latest result remained above district and state levels. Science improved by nearly 10 percentage points year over year. Martin Hall Detention Center cannot be fairly compared with Medical Lake because of its very small, specialized enrollment and limited reported data; missing metrics should not be interpreted as zero or poor performance. Families seeking a traditional high school experience will find Medical Lake to be the area’s primary option, with especially strong graduation outcomes and a clear need for continued math improvement.
