Summary:
Morton, Washington, has two public schools serving grades PK–12: Morton Elementary School serves PK–4, while Morton Junior-Senior High serves grades 7–12; together, the small rural district serves about 399 students.
The schools offer different strengths. Morton Elementary School has shown the strongest recent improvement, rising from the 33rd to the 63rd statewide percentile between 2023–2024 and 2025–2026 and moving from a two-star to a three-star rating. Its latest English language arts proficiency was 58.49% and mathematics proficiency was 49.06%, both above the district and state aggregate rates. The school also had a lower student-teacher ratio than the high school, 13.7 compared with 17.6, and slightly higher per-student spending. Third-grade ELA was especially strong at 65.38%. Although overall elementary math performance improved significantly, third- and fourth-grade math results were each slightly below their corresponding state rates, so continued attention to math would be helpful.
Morton Junior-Senior High also holds a three-star rating and has important strengths, including an 89% graduation rate—6.4 percentage points above Washington’s rate—and science proficiency of 56.67%, above the state’s 50.95%. Eleventh-grade science was particularly strong at 61.29%, and eighth-grade ELA reached 64.29%. The main concern is mathematics: overall proficiency fell to 31.82% in 2025–2026, including just 25% in 10th grade, a decline of more than nine points from the prior year. The Morton School District ranks in the 69th statewide percentile, suggesting a generally solid system, while secondary math remains the clearest priority for improvement.
