Summary:
ZIP code 98926, which includes the Ellensburg area and nearby Kittitas County communities, has three high-school-level programs serving grades 8–12: Ellensburg High School, Ellensburg Open Doors, and Parke Creek Treatment Center, with 1,006 students combined.
Ellensburg High School is the area’s main comprehensive high school, serving grades 9–12 with 957 students. It has the strongest documented academic profile, including a 90.6% graduation rate in 2024–25, above both the Ellensburg School District and Washington state. Its 6.1% dropout rate was also below district and state levels. In 2025–26, the school exceeded state proficiency rates in English Language Arts and science, with especially strong results in 11th-grade science. The school’s overall ranking placed it at the 79th percentile statewide. Mathematics is the clearest area for improvement: all-grades math proficiency was 41.98%, slightly below district and state results, although 10th-grade math was above the state rate.
Ellensburg Open Doors is a much smaller grades 11–12 alternative or re-engagement program with 38 students. Its 78.95% free/reduced-price lunch rate indicates a different level of student need, and the available data does not include comparable graduation or test results. Parke Creek Treatment Center serves only 11 students in grades 8–12 through a specialized program connected to the Kittitas School District. It reports an 11:1 student-teacher ratio and $21,438 in per-student spending, reflecting its small, specialized setting. These two programs are best evaluated by their missions and available support rather than ranked directly against the comprehensive high school.
