Summary:

Prosser School District serves about 2,534 students across six schools in grades prekindergarten through 12: three elementary schools, one middle school, and two high schools. The district includes Keene-Riverview Elementary for grades PK–2, Prosser Heights Elementary and Whitstran Elementary for grades K–5, Housel Middle School for grades 6–8, and Prosser High School and Prosser Opportunity Academy for grades 9–12.

Prosser High School stands out for its overall results. Its ranking rose to the 52nd percentile in 2025–2026, compared with 38th percentile for Prosser Heights Elementary, 27th for Housel Middle School, and 11th for Whitstran Elementary. The high school had the district’s strongest English results, with 61.14% proficient, and reported a 94.3% graduation rate and 2.6% dropout rate. Prosser Heights Elementary was the strongest elementary school academically, leading in math and science and exceeding the state math proficiency rate. Housel Middle School showed encouraging year-over-year gains, especially in English and science.

Whitstran Elementary is the clearest area of concern, with declining rankings and the lowest reported proficiency in English, math, and science. Its fifth-grade results were particularly weak, suggesting that families and district leaders may want to examine academic supports in the upper elementary grades. Math is also an important improvement area at both Housel Middle School and Prosser High School. Keene-Riverview Elementary has the lowest student-teacher ratio, at 13.1, but no school-level assessment results were supplied. Current test results for Prosser Opportunity Academy were suppressed, so they should not be interpreted as zero or low performance. Overall, the district combines strong high-school completion results with uneven academic performance across elementary and middle schools.
