Summary:
ZIP code 98356 contains one public high school, Morton Junior-Senior High, which serves grades 7–12, enrolls 205 students in Morton, WA, and is part of Morton School District.
The school’s clearest strengths are science, graduation, and 8th grade ELA. In 2025–2026, all-grade science proficiency is 56.67%, above the district’s 50.00% and the state’s 50.95%; 11th grade science is 61.29% versus 48.78% statewide, and 8th grade science is 51.72% versus 48.78%. The graduation rate is 89.0%, above Washington’s 82.6%. 8th grade ELA is 64.29%, compared with 50.90% statewide. The school’s state ranking improved from 2 stars in 2023–2024 to 3 stars in 2025–2026, at the 54th percentile.
Math is the main academic concern. All-grade math is 31.82%, below the state’s 43.11% and down from 41.11% the prior year; 10th grade math is 25.00% versus 35.42%, and 7th grade math is 32.14% versus 41.31%. Only 8th grade math is near state level, at 39.29% versus 38.80%. ELA is mixed: all-grade ELA is slightly above state, but 10th grade ELA is 51.52% versus 64.41% and 7th grade ELA is 48.15% versus 53.23%. Context matters: 205 students, 55.12% free/reduced lunch, $19,570 per-student spending, and a 17.6:1 student-teacher ratio. The latest school-level dropout figure is missing; the only school figure shown is 16.2% from 2021–2022, while the 2024–25 state rate is 9.8%.
