Summary

Whitstran Elementary is a small K–5 school in Prosser, Washington, serving 261 students in the Prosser School District. The school serves a relatively high-need community, with 78.54% of students qualifying for free or reduced-price lunch in 2024–25. Its student-teacher ratio was 17.5, and its 2023–24 spending was $21,535 per student.

Academic results are currently a significant concern. In 2025–26, 21.62% of students were proficient in English language arts, 26.79% in math, and 28.21% in science—below both district and Washington averages in all three subjects. Results also declined from the prior year, especially in science, which fell from 41.03% to 28.21%. Fifth grade is the clearest area of weakness, with 15.38% proficiency in both ELA and math. The school ranked in the 11th statewide percentile, down from the 25th percentile the previous year. By comparison, nearby Prosser Heights Elementary posted proficiency rates of 39.34% in ELA, 44.92% in math, and 45.59% in science, while ranking in the 38th percentile.

Whitstran’s results are not the lowest among nearby schools, exceeding several schools in the surrounding area in selected subjects. However, Thompson Elementary School in Grandview is a particularly notable comparison: despite having a higher free/reduced-price lunch rate of 83.24%, it reached 45.04% proficiency in ELA, 50.62% in math, and 48.78% in science. Whitstran’s strongest reported subgroup was migrant students, whose ranking reached the 93rd percentile. Earlier science and math results were also stronger, suggesting the school has demonstrated capacity for improvement. Parents may want to ask about fifth-grade instruction, attendance, staffing stability, intervention programs, and how the school is building on practices that have worked well for migrant students.
