Summary

Three Rivers Elementary is a large public school in Pasco, Washington, serving about 657 students in prekindergarten through fifth grade as part of the Pasco School District. For 2025–2026, it ranked at the 35th percentile statewide, a substantial improvement from the 13th percentile the previous year. Its latest ranking is the school’s strongest in the available six-year history, although it remains below the statewide midpoint.

The school’s 2025–2026 test results were above the Pasco School District average in all three subjects: 39.69% proficiency in English language arts, 38.87% in math, and 51.00% in science. Science is the clearest strength: the result was nearly equal to Washington’s 50.95% and was second-highest among nearby Pasco schools, behind only Ruth Livingston Elementary. Three Rivers also outperformed Mark Twain Elementary, Columbia River Elementary, and Sunset View Elementary School in selected subjects. Math proficiency rose from 28.01% to 38.87% in one year, while science increased from 29.09% to 51.00%.

Parents may want to watch fourth-grade results closely: fourth-grade ELA proficiency was 31.19%, and math proficiency was 27.52%, the lowest tested-grade results in both subjects. ELA overall also remains the largest statewide gap, at 13.12 percentage points below Washington’s rate. At the same time, results improved across every tested subject, and effectiveness rankings for English-language learners and students from low-income backgrounds rose sharply. The school serves a relatively high-need community, with 64.84% of students qualifying for free or reduced-price lunch in 2024–2025. Overall, Three Rivers shows encouraging momentum, with science as a standout strength and sustained improvement—especially in fourth-grade instruction and ELA—being the key next challenge.
