Summary:
ZIP code 99402 has one listed elementary school, Asotin Elementary, serving students from Pre-K through fifth grade in the Asotin-Anatone School District. The school enrolls 311 students and has a student-teacher ratio of 16.8 to 1. Since there is only one elementary school in the ZIP code, families cannot compare several local schools directly; instead, the most useful picture comes from reviewing Asotin Elementary’s results against district and Washington state performance.
Asotin Elementary is performing strongly statewide. In 2025–2026, 61.38% of students were proficient in English language arts, compared with 52.81% statewide. Math was the school’s strongest subject, with 68.28% proficiency—more than 25 percentage points above the state rate of 43.11%. Science proficiency was 65.96%, about 15 points above the state. The school’s district ranks 27th out of 238 districts statewide, placing it in the 89th percentile, and has a four-star rating. The school itself ranked in the 79th percentile most recently, improving substantially from the prior year’s 61st percentile.
Grade-level results show particularly strong third-grade ELA performance, with 70% proficiency, and fourth-grade math performance, with 72.92% proficiency. Fifth-grade math remained above the state average at 55.32%, but the drop from fourth grade may be worth monitoring. Upper-grade ELA results also exceeded state averages, although by smaller margins: 56.25% in fourth grade and 57.45% in fifth grade. Results improved year over year in every tested subject, led by a nearly 21-point increase in science. The school’s 40.19% free-or-reduced-price lunch rate and $22,238 per-student spending figure provide additional context, though they do not by themselves explain academic outcomes. Overall, the data indicate a strong school, especially in math and science, with upper-grade literacy and fifth-grade math as areas to watch.
