Summary

Riverside Middle School in Chattaroy, Washington, is a public school serving 325 students in grades 6–8 in a relatively small, higher-need community about 5.4 miles from Deer Park Middle School. Riverside is part of the well-regarded Riverside School District, which ranks in the 74th percentile statewide. The school itself ranks in the 51st percentile, placing it in the middle range statewide.

Riverside’s 2025–26 proficiency rates were 43.83% in English language arts, 40.07% in math, and 42.86% in science. Its math performance is a relative strength: Riverside outperformed most nearby Spokane School District comparison schools and was nearly even with Northwood Middle School and Mountainside Middle School. Seventh-grade math was especially encouraging, at 44.34%, above both state and district averages. However, English language arts declined from 51.66% to 43.83% in the latest year, making literacy the clearest schoolwide improvement priority. Sixth grade also lagged state averages in both ELA and math.

Compared with nearby schools, Riverside is substantially stronger than Shaw Middle School, Glover Middle School, Salk Middle School, and Garry Middle School in most subjects. It trails higher-performing schools such as Highland Middle School, Lakeside Middle School, and Deer Park, especially in ELA and science. Notable strengths include strong effectiveness rankings for special education students (77th percentile) and low-income students (68th percentile). Science improved to 42.86%, but sustaining that gain, reversing the recent ELA decline, and improving sixth-grade achievement are the school’s main opportunities.
