Elementary Schools in Prosser School District

Summary:

The Prosser School District operates three elementary schools (Prosser Heights Elementary, Keene-Riverview Elementary, and Whitstran Elementary) serving grades PK-5 in a community with significant economic need, where 71% to 79% of students qualify for free or reduced-price lunch.

Among the schools, Prosser Heights Elementary stands out as the highest-performing, with the strongest test scores in English and math and a clear record of improvement over the past three years. Keene-Riverview Elementary serves only grades PK-2, offering the smallest class sizes, while Whitstran Elementary has the highest per-student spending but the lowest test scores among the schools with tested grades.

As a whole, the district's academic performance trails the state average by a notable margin, though there are pockets of relative strength, such as in 3rd-grade math and science proficiency. The consistent improvement at Prosser Heights Elementary and the focused early childhood model at Keene-Riverview Elementary represent strategic strengths within the district's ongoing efforts to support student achievement.
