Summary

Mossyrock Junior/Senior High School is a small public school serving 281 students in grades 7–12 in the rural Mossyrock area of southwest Washington, within the Mossyrock School District. The school offers a relatively favorable 14.8 student–teacher ratio and spent $18,961 per student in 2023–24. Its student population has a higher level of economic need than most nearby traditional high schools, with 61.92% of students qualifying for free or reduced-price lunch in 2024–25.

Academically, English language arts is the school’s strongest area. In 2025–26, 51.94% of students were proficient in ELA, close to Washington’s 52.81% and well above the district’s 43.41%. That result was better than Toutle Lake High School, though below Toledo High School, Winlock Senior High, Onalaska High School, and Morton Junior-Senior High. Math is the clearest concern: proficiency was 21.71%, below both the district’s 26.45% and the state’s 43.11%. Science was more encouraging at 40.48%, above the district and higher than Toledo and Toutle Lake, although still below the state.

Graduation is a notable strength. The school’s latest reported school-level graduation rate was 91.0% in 2023–24, substantially above Washington’s 82.7%; the district also reported 91.0% in 2024–25. The school’s statewide ranking remains in the lower-middle range, at the 32nd percentile with two stars in 2025–26, largely reflecting persistent math weakness. Still, its small size, staffing levels, improving science performance, and near-state ELA results provide a solid foundation. Families may also note that nearby Mossyrock Academy is a separate, much smaller school in the same district, serving only 16 students, with many results suppressed rather than reported as zero.
