Summary

Carbonado Historical School 19 is a small public school in the Carbonado, Washington, area, serving 176 students in grades K–8 through the highly ranked Carbonado School District. The district ranks 36th of 238 statewide, while the school ranks 284th of 1,138 Washington schools for 2025–2026, placing it in the 75th percentile with a four-star rating. Its K–8 structure gives families the option of staying in a small-school setting through middle school, unlike most nearby comparison schools, which serve only elementary grades.

Academic results are comfortably above Washington averages: 66.12% of students are proficient in English language arts, 60.33% in math, and 55.26% in science. Math is the school’s clearest statewide strength, exceeding the state rate by more than 17 percentage points, while ELA is more than 13 points higher. Carbonado generally outperforms nearby schools such as Wilkeson Elementary School, Sunrise Elementary, Foothills Elementary, and Orting Elementary School. However, it trails especially strong performers Mountain Meadow Elementary and Tehaleh Heights Elementary School. Comparisons should be viewed as directional because Carbonado’s results include middle-school students.

The school’s 13.8 student-teacher ratio is the lowest among the nearby schools with available data, which may support more individualized attention. Per-student spending is relatively high at $18,856, a pattern often associated with a small enrollment. Results vary by year: ELA has remained fairly steady, math has slipped from the mid-60% range, and science fell from 70.00% in 2024–2025 to 55.26% in 2025–2026. Seventh-grade math was particularly strong at 78.57%, while eighth-grade ELA and science were weaker. Figures for grades 3, 4, and 6 were suppressed and unknown, not zero. Carbonado’s 34.66% free/reduced-price lunch rate is moderate and rising, yet the school continues to perform above most local competitors and the state overall.
