Summary

Riverside Elementary in Chattaroy, Washington, is a public school serving about 380 students in prekindergarten through fifth grade as part of Riverside School District. Located in a rural-to-suburban area northeast of Spokane, the school serves a varied community, with 57.63% of students qualifying for free or reduced-price lunch. Its student-teacher ratio is favorable at 14.3, and its 2025–2026 statewide ranking—259th of 1,138 elementary schools, or the 77th percentile—earned it a four-star rating.

The school’s most notable story is its long-term improvement. Riverside moved from the low 20th percentile and a one-star rating in the late 2010s to the 77th percentile today, including a 200-position gain in the latest year. Mathematics is its clearest academic strength: 50.21% of students were proficient in math in 2025–2026, 7.10 percentage points above the state average and 6.21 points above the district average. Science proficiency was 52.78%, slightly above the state, while English Language Arts was 51.25%, close to average but 1.56 points below the state. Riverside’s 70th-percentile effectiveness ranking for students from lower-income households is another positive indicator.

Results vary considerably by grade. Fourth grade was especially strong, with 63.24% proficient in math, while fifth grade was the main improvement area: 46.79% in ELA, 39.81% in math, and 52.78% in science. The nearby same-district Chattaroy Elementary is an important benchmark, outperforming Riverside by 9.17 points in ELA and 17.50 points in math, although its latest ranking data are older. Riverside also trails top-performing Meadow Ridge Elementary, Midway Elementary, and Colbert Elementary, but it ranks ahead of nearby Creekside Elementary School and Brentwood Elementary School. Overall, Riverside is an above-average, rapidly improving school with strong math momentum and clear fifth-grade opportunities.
