Summary

Prosser High School is a public school serving grades 9–12 in Prosser, Washington, with 877 students and a comprehensive high-school program in a smaller Tri-Cities-area community. It is part of the Prosser School District and currently ranks 189th out of 396 Washington high schools, around the 52nd percentile. This is a substantial improvement from the school’s ranking in the lower third of the state during the previous several years.

Academically, Prosser stands out among nearby comprehensive high schools. In 2025–26, 61.14% of students were proficient in English language arts, above the Washington rate of 52.81%. Math proficiency was 32.48% and science proficiency was 41.32%—both below state averages but considerably higher than at Sunnyside High School, Kiona-Benton City High School, Mabton Junior Senior High, and Grandview High School. Math has improved from 15.18% proficient in 2023–24, but it remains the clearest academic priority. Science is also below the state benchmark, though it is a strong local comparison point.

Completion outcomes are a major strength. Prosser’s 2024–25 graduation rate was 94.3%, compared with 82.6% statewide and 80.2% at Sunnyside, 77.4% at Kiona-Benton, and 84.3% at Grandview. Its dropout rate was just 2.6%, well below Washington’s 9.8%. The school reported 19.6 students per teacher and $18,068 in per-student spending, figures that are competitive locally. Prosser serves a relatively high-need community, and its recent gains across achievement, graduation, dropout reduction, and student-group effectiveness suggest broad momentum. Families should view continued progress in math and science as the key factor that could sustain the school’s upward trajectory.
