Riverside School District

Riverside School District includes five schools serving students from pre-kindergarten through grade 12: two elementary schools, one middle school, one high school, and one alternative school, with 1,570 students overall. The district ranks 62nd of 238 Washington districts, placing it in the 74th percentile with a four-star rating. Overall results are strongest in elementary math and high school English, although performance varies notably from school to school.

Chattaroy Elementary is the district’s clearest academic standout, with 60.42% of students proficient in English and 67.71% in math during 2025–2026. It had the highest math results in the district and improved significantly in English from the prior year, despite having the highest reported free- and reduced-price lunch participation. Riverside High School also stands out, leading all schools in English proficiency at 67.39% and reporting a 95.1% graduation rate. Its main area for improvement is math, where proficiency was 34.09%. Riverside Elementary offers balanced performance across English, math, and science and has the district’s lowest student-teacher ratio.

Riverside Middle School is the main improvement priority among the traditional schools, with results below district averages in English, math, and science and a recent ranking decline. Science improved substantially, but English and math fell year over year. Independent Scholar reports lower all-grade math and science proficiency, but its small K–12 alternative-school setting and several state-suppressed results make direct comparisons difficult; suppressed figures should be treated as unavailable, not zero. Parents comparing schools should look beyond rankings: the district offers strong elementary math, high school literacy, and graduation outcomes, while middle-school support, high-school math, and fifth-grade performance deserve particular attention.
