Summary:
Riverside Middle School is the only middle school in Riverside School District, serving grades 6–8 and 325 students in the Chattaroy, Washington, area. The school has a 16.7-to-1 student–teacher ratio, and 56.62% of students received free or reduced-price lunch in 2024–2025. Since there is only one middle school in the district, families cannot compare it with another local middle school using this data.
The school’s clearest academic strength is math, especially in 7th grade. In 2025–2026, 44.34% of 7th graders were proficient in math, exceeding both the district result of 42.37% and the state result of 41.31%. Riverside also slightly exceeded the district in 6th-grade math and 6th-grade ELA, and it was slightly above the state in 8th-grade math. At the grade level, several 8th-grade results were close to district performance, including ELA, math, and science. These results suggest that the school has areas of solid performance even though its overall results trail broader averages.
English language arts is the biggest area for improvement. Overall ELA proficiency was 43.83%, compared with 50.93% in the district and 52.81% statewide; 6th-grade ELA was particularly weak at 37.50%, versus 48.27% statewide. Overall math proficiency was 40.07%, below both the district and state, while science improved substantially from 32.00% to 42.86% year over year but remained below comparison results. The school’s ranking stayed near the middle of Washington schools, with its percentile declining from 59th to 51st most recently. For families, the main takeaway is a mixed profile: relative strength in math, encouraging science improvement, and a need for stronger literacy support.
