Cosmopolis School District

Cosmopolis School District has one small elementary school, Cosmopolis Elementary School, serving approximately 175 students in kindergarten through sixth grade in Cosmopolis, Washington. The school has a 16.5-to-1 student–teacher ratio, and 57.14% of students qualified for free or reduced-price lunch in 2024–2025. Because it is the district’s only school, district and school results are the same, so there are no local school-to-school comparisons.

Overall, Cosmopolis Elementary School performed below Washington averages in 2025–2026. Proficiency was 41.38% in English language arts, 26.44% in math, and 42.86% in science, compared with statewide rates of 52.81%, 43.11%, and 50.95%. Math is the clearest area needing attention, especially in grades 3 through 5: fourth-grade math proficiency was 18.18%, more than 31 percentage points below the state. Science also declined from 51.85% in 2024–2025 to 42.86% in 2025–2026. Families should also note that small-school percentages can change noticeably when only a few students’ results shift.

There are encouraging signs, particularly in the upper grades and in English language arts. Sixth-grade students reached 52% proficiency in ELA, exceeding the statewide rate of 48.27%, while sixth-grade math was 40%, essentially matching the state’s 39.79%. ELA proficiency across the school rose 11.27 percentage points from the prior year, and grade-level ELA results improved steadily from third through sixth grade. The school’s ranking also improved from the 24th percentile and one star in 2024–2025 to the 30th percentile and two stars in 2025–2026, although it remained below the statewide midpoint. For parents, the main questions are how the school is strengthening math foundations in grades 3–5, sustaining ELA progress, and responding to the recent science decline.
