Summary
Shelton High School is a public grades 9–12 school serving 1,455 students in the Shelton community and is the largest traditional high school in the Shelton School District. About 58.42% of students qualified for free or reduced-price lunch in 2024–2025, and the student-teacher ratio was 18.8:1. The school ranked 285th of 396 Washington high schools, placing it in the 28th percentile and earning one star—an improvement from the 20th percentile in 2023–2024, though still below the state midpoint.
Academic results vary sharply by subject. English Language Arts is Shelton’s strongest area: 52.98% of students were proficient in 2025–2026, nearly matching the Washington rate of 52.81% and exceeding the district rate of 39.76%. Mathematics is the clearest challenge, with only 15.48% proficient compared with 43.11% statewide; math proficiency has remained between about 12% and 17% for four consecutive years. Science proficiency was 38.73%, below the state’s 50.95% but above the district’s 35.25%. The graduation rate was 83.8% in 2024–2025, slightly above the state rate of 82.6%, but it has declined recently while the dropout rate rose to 11.6%, higher than the statewide 9.8%.
For a similarly large comparison, North Thurston High School serves a similar number of students but has considerably stronger results, including a 67th-percentile ranking, 73.80% ELA proficiency, an 88.2% graduation rate, and a 7.7% dropout rate. North Mason Senior High School is a closer overall comparison, with a 34th-percentile ranking, somewhat higher ELA and math results, and a lower dropout rate. As a higher-performing large-school benchmark, Capital High School posted an 85th-percentile ranking and substantially higher proficiency in all three subjects. Overall, Shelton’s improving ELA performance and relatively solid graduation rate are encouraging, but mathematics, science, and student persistence remain important priorities.
