Summary

Whitstran Elementary is a public K-5 school serving 261 students in Prosser, Washington, operating within the Prosser School District, which ranks in the lower quarter of the state.

Academically, the school's overall test scores are below state averages, but it shows relative strengths in math and science compared to its own district. A standout success is its exceptional effectiveness in educating migrant students, ranking in the 80th percentile statewide for that group. However, the school's performance has been inconsistent over time, and it is outperformed within its district by Prosser Heights Elementary, which has higher proficiency rates in English and math despite lower per-student spending.

Compared to other regional schools in high-need areas, Whitstran's performance is middling; it scores higher than some schools in the Sunnyside and Kiona-Benton City districts but is outperformed by others like Thompson Elementary in Grandview. A key point for parents is that Whitstran has the highest per-student spending in its district, yet this has not translated to superior academic outcomes compared to its local peers, indicating that factors beyond funding significantly influence student success.
