Summary:
Prosser, Washington, has seven schools serving about 2,646 students in grades pre-K through 12, including three elementary schools, one middle school, two high-school programs, and one alternative school; most are part of the Prosser School District, while Red Comet at Toppenish School District is connected to the Toppenish School District. The schools vary considerably in results, so the districtwide ranking does not tell the whole story.
Prosser High School is the strongest overall performer. Its ranking improved from the 27th percentile to the 52nd percentile over three years, and it reports a 94.3% graduation rate and a 2.6% dropout rate. It has especially strong English language arts results, with 61.14% of students proficient, although math remains weaker at 32.48%. Among elementary schools, Prosser Heights Elementary stands out, leading the area in math and science and improving its ranking in each of the past three years. Its math proficiency, 44.92%, is slightly above the state rate. Keene-Riverview Elementary has the lowest reported student-teacher ratio at 13.1, but no achievement results were provided for comparison.
Whitstran Elementary needs the most attention among the traditional Prosser schools. Its ranking fell to the 11th percentile, and proficiency declined in ELA, math, and science, leaving it below district and state levels in every subject. Housel Middle School is improving, but remains below district and state averages, particularly in math. The alternative programs require cautious interpretation because of small enrollments and suppressed data. Red Comet reports a 55.8% graduation rate and a 23.2% dropout rate, while current results for Prosser Opportunity Academy are largely unavailable. Overall, families will find the strongest measured outcomes at Prosser High and Prosser Heights, with secondary math and Whitstran’s schoolwide performance the clearest areas for improvement.
