Summary
Lake Roosevelt Junior/Senior High School is a public school in rural Coulee Dam, Washington, serving grades 7–12 and enrolling 308 students. It is part of the Grand Coulee Dam School District, which serves a relatively high-need community; 68.51% of students qualified for free or reduced-price lunch in 2024–25. The school is considerably larger than nearby comparison schools, including Wilbur Secondary School with 109 students, Lake Roosevelt Alternative School with 33, and Nespelem High School with 19.
The main academic concern is consistently low performance on state assessments. In 2025–26, 23.66% of students were proficient in English language arts, 13.08% in math, and 26.32% in science—well below Washington rates of 52.81%, 43.11%, and 50.95%. Math is the clearest priority, with results staying between 8.07% and 13.14% over the last four reported years. ELA also declined from 34.71% in 2022–23 to 23.66% in 2025–26. By comparison, Wilbur reported 50% proficiency in ELA, 43.14% in math, and 37.14% in science. Lake Roosevelt’s statewide ranking was at the 7th percentile in 2025–26, while the district ranked approximately at the 4th percentile.
Graduation is a notable strength: the school reported a 90.0% graduation rate in 2024–25, above Washington’s 82.6%, and rates were also above the state in 2022–23 and 2020–21. Staffing has improved, with the student-teacher ratio falling to 13.5 in 2024–25, although assessment results have not clearly improved alongside increased spending. Subgroup rankings indicate uneven outcomes, particularly for low-income students, female students, and Native American students; small subgroup sizes may cause year-to-year volatility. Overall, families may see a school that appears more successful at helping students graduate than at producing grade-level test proficiency, with sustained math, literacy, engagement, and student-support efforts likely to be important.
