About Prosser School District
Families in zip code 99350 (Prosser, Washington) are assigned to Prosser School District for public education through 12. This overview covers the district’s funding levels, scale, rating, and what to expect from the enrollment process if you’re moving to or within this zip code.
Funding and Resources

Near-average districts typically provide core academic programs with adequate staffing, though program breadth may be more limited than in higher-funded systems. Per-pupil spending directly affects teacher compensation, class sizes, elective course offerings, technology access, and the depth of student support services — making it one of the most meaningful structural indicators of district capacity.
District Scale and Program Breadth
At 6 schools serving grades K–12, Prosser School District qualifies as a mid-sized district serving students from K–12. The district enrolls approximately 2,414 students in total. Mid-sized districts strike a balance between community-scale relationships and sufficient program breadth. Most offer core academic tracks, basic extracurricular programs, and adequate student support services.
Understanding the 3/10 Rating
With a rating of 3/10 (below average), Prosser School District ranks among Washington’s below average-rated school systems. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in the U.S. Department of Education’s EDFacts collection. We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Washington is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
Prosser School District carries a below-average rating, with reading and math proficiency rates below typical Washington benchmarks on state assessments. A below-average score reflects test performance relative to other districts — not necessarily teaching quality or school culture, and some of these districts have schools with strong communities and dedicated staff. Families should research specific school quality, visit in person, and ask about available programs. Also ask about open enrollment and magnet options that may offer alternatives to the default attendance-zone assignment.
