Summary:
ZIP code 98237 has one listed elementary school, Concrete Elementary, serving kindergarten through fifth grade in the small community of Concrete. The school enrolls 308 students and is part of the Concrete School District. Because it is the only elementary school in the ZIP code, parents cannot compare it with another local elementary school; the most useful comparisons are with district and Washington state results.
In 2025–2026, Concrete Elementary’s proficiency rates were 24.58% in English Language Arts, 18.64% in math, and 25.93% in science. These results were below Washington averages of 52.81%, 43.11%, and 50.95%, respectively. Math was the school’s strongest relative subject because it exceeded the district rate by 3.03 percentage points, although it remained well below the state average. Fourth grade had the highest reported results in both English Language Arts and math, while third grade had the lowest. Fifth-grade math results were suppressed and are not available, so they should not be interpreted as zero or as evidence of particularly weak performance.
Parents should also note the school’s recent downward trend. From the prior year, English Language Arts proficiency fell 14.15 percentage points, science fell 17.31 points, and math fell 3.74 points. The school’s statewide ranking declined from the 23rd percentile in 2023–2024 to the 11th percentile in 2025–2026, while the district ranked at the 14th percentile statewide. About 66.88% of students qualified for free or reduced-price lunch, and the student-teacher ratio was 18.8 to 1. Families considering the school may want to ask about plans to improve reading and science, support third graders, and determine whether the latest declines represent a temporary setback or a continuing pattern.
