Best Public Schools in Zip Code 98284

Zip code 98284 has seven public schools serving elementary, middle, and high school students in the Sedro-Woolley School District, an area where schools serve 3,727 students and generally face substantial economic need.

School performance varies considerably. Sedro Woolley Senior High School is the strongest traditional high school, with a 94.2% graduation rate and the highest ELA proficiency among these schools, although its math proficiency is relatively low at 23.78%. State Street High School is the greatest concern, with a 50% graduation rate, a 15.6% dropout rate, a fourth-percentile ranking, and 20% science proficiency; its math result is suppressed and should not be interpreted as zero. Among elementary schools, Mary Purcell Elementary School has the strongest improvement story, rising from the 17th to the 36th percentile and leading the area in science proficiency at 52.17%. Central Elementary School has the highest overall math proficiency at 37.54%, while Samish Elementary School has the best student-teacher ratio and strong grade-level results despite a sharp recent decline.

Evergreen Elementary School shows broad year-over-year improvement and particularly strong science results, though its overall ranking remains modest. Cascade Middle School performs below district and state averages in ELA, math, and science, with especially weak eighth-grade results. Across the district, proficiency trails statewide averages, particularly in math. Parents comparing schools should look beyond overall rankings because grade-level results vary widely: some schools have strong fourth- or fifth-grade outcomes but much weaker performance in other grades. The most important priorities appear to be targeted support at State Street, high-school math improvement, closer attention to Cascade’s eighth grade, and investigation of Samish’s recent decline.
