Summary:
ZIP code 98584 has three high schools serving grades 9–12 in the Shelton area: Shelton High School, Cedar High School, and Shelton Open Doors. All are part of the Shelton School District and together enroll 1,577 students. The area is dominated by Shelton High, which serves about 92% of the students and offers the broadest range of academic and outcome information. Cedar is a much smaller school, while Shelton Open Doors is a very small alternative program with limited comparable data.
Shelton High School has the strongest graduation data, with an 83.8% rate in 2024–2025, slightly above the state rate and well above the district rate. Its ELA and science results are also stronger than the district’s, with ELA essentially matching the state. However, math is a major weakness: only 15.48% of students were proficient, compared with 43.11% statewide. The school’s ranking has improved over three years, though it remains below the statewide midpoint. Its dropout rate of 11.6% is another issue for families to consider.
Cedar High School has the highest current ELA proficiency, at 59.09%, and a lower student-teacher ratio of 13.8 compared with Shelton High’s 18.8. Its math performance is slightly better than Shelton High’s but still far below the state level, and its overall ranking declined in 2025–2026. Because Cedar enrolls only 100 students, its results can change noticeably from year to year; its current science result is suppressed rather than a zero. Shelton Open Doors serves just 22 students and has no comparable academic or graduation results listed. Overall, math improvement and student persistence are the most important shared concerns, while school size and program type should guide comparisons.
