Summary:
ZIP code 98323 has one listed school, Carbonado Historical School 19, a small K–8 campus serving 176 students in the Carbonado community. The school is part of the highly ranked Carbonado School District, which ranks 36th of 238 Washington districts, placing it in the 85th percentile. Because there is only one school in the ZIP code, parents cannot compare schools locally and should focus on the school’s academic results, grade-level patterns, and small-school environment.
Carbonado Historical School 19 has maintained a four-star rating and ranked between the 75th and 81st percentile statewide over the past three listed years. In 2025–26, students performed above Washington averages in every reported subject: 66.12% were proficient in English Language Arts compared with 52.81% statewide, 60.33% in math compared with 43.11%, and 55.26% in science compared with 50.95%. Math is the clearest strength, especially in seventh grade, where 78.57% of students were proficient compared with 41.31% statewide. The school also reports a relatively favorable 13.8-to-1 student-teacher ratio, 34.66% participation in free or reduced-price lunch, and $18,856 in per-student spending.
Parents should pay particular attention to differences among grade levels. Fifth- and seventh-grade results were strong in several subjects, while eighth-grade English Language Arts was considerably weaker than the state average—28.57% proficient compared with 50.90%—and eighth-grade science was slightly below average. Schoolwide science proficiency also fell from 70.00% in 2024–25 to 55.26% in 2025–26, making that trend worth asking about. At the same time, small enrollment means that a few students can significantly affect percentages, and several grade-level results are suppressed. Overall, the school offers consistently above-state performance in a small K–8 setting, with math as its standout strength and middle-school literacy and science as the main areas for follow-up.
