Summary:
Grand Coulee Dam School District has two high-school-grade schools in the Grand Coulee Dam area: Lake Roosevelt Junior/Senior High School, serving grades 7–12, and Lake Roosevelt Alternative School, serving grades 9–12, with 341 students combined. The junior/senior high school serves most students, with 308 enrolled, while the alternative school serves 33 students with a different program and higher level of reported economic need.
Lake Roosevelt Junior/Senior High School has a strong recent graduation rate of 90% for 2024–2025, above Washington’s 82.6% rate and close to the district’s 92%. However, academic assessment results are much weaker: 23.66% of students met standards in English language arts, 13.08% in math, and 26.32% in science in 2025–2026, compared with substantially higher statewide results. Math is the clearest academic concern, while science showed the only meaningful year-over-year improvement. The school’s 13.5:1 student–teacher ratio is considerably lower than the alternative school’s ratio.
Lake Roosevelt Alternative School has a much smaller enrollment and serves a higher-need population, with 90.91% of students qualifying for free or reduced-price lunch, compared with 68.51% at the junior/senior high school. Its latest supplied school-level graduation rate was 63% in 2022–2023, and its dropout rate was 26.3% in 2021–2022; these figures are from different years and should not be treated as current, directly comparable rates. Assessment results are limited, with some science data suppressed because of the small number of students. Families comparing the schools should consider the alternative school’s specialized mission, student needs, and smaller size rather than relying on rankings alone.
