Medical Lake High School is the only high school listed in the Medical Lake School District, serving grades 9–12 in the Medical Lake, Washington area. The school enrolls 506 students, has a 17.9-to-1 student–teacher ratio, and spends approximately $17,380 per student. Because it is the district’s only high school, families cannot compare it with another high school within the district, but its results can be compared with district and statewide measures.
The school’s strongest overall result is its 96.3% graduation rate for 2024–2025, matching the district and exceeding Washington’s 82.6% rate by 13.7 percentage points. Academic performance is strongest in science and English language arts. In 2025–2026, 61.82% of students met the science standard, which was more than 10 percentage points above the state rate. English language arts proficiency was 60.95%, exceeding both the district and state all-grades results. The school also has a 4-star ranking and was at the 72nd percentile in the latest ranking information, indicating an above-average overall standing.
Math is the clearest area needing improvement. Only 38.1% of students met the latest math standard, placing the school below both the district and the state; math performance also fell 12.37 percentage points from the previous year. English language arts declined by 14.75 points as well, although its latest result remained above district and state all-grades rates. Science moved in the opposite direction, improving nearly 10 points year over year. For parents, the overall picture is a school with excellent graduation and completion outcomes, solid science and ELA performance, and a need for focused attention on math and the recent decline in ELA results.
