Summary
Yelm High School 12 is a large traditional public high school in the Yelm area of Washington, serving grades 9–12 and 1,693 students through the Yelm School District. The school ranks 142nd of 396 Washington high schools, placing it in the 64th percentile for 2025–26—a notable improvement from the 48th percentile the previous year. Yelm offers a mixed academic picture: English Language Arts is a clear strength, while mathematics remains the biggest concern. Its science performance is slightly above the state average, and its overall standing is stronger than nearby Bethel High School, Tenino High School, and River Ridge High School.
In 2025–26, 63.32% of Yelm students were proficient in ELA, well above the district’s 52.24% and the state’s 52.81%. That result was competitive with Rainier Senior High School and higher than Bethel and Tenino, although it trailed Olympia High School and North Thurston High School. Science proficiency was 53.71%, slightly above the statewide 50.95%. Math, however, was only 31.41%, about 12 percentage points below both the district and state. Although math has improved from 23.47% in 2022–23, it remains a persistent schoolwide challenge.
Parents may also want to watch student completion trends. Yelm’s 2024–25 graduation rate was 82.2%, close to the state’s 82.6% but down from 87.6% the prior year; its 10.3% dropout rate was higher than the state’s 9.8%. Subgroup effectiveness varies: recent results were especially strong for English Language Learners, while effectiveness for students receiving special education services ranked in the 13th percentile. The reported student-teacher ratio of 24.6 is higher than at most nearby comprehensive high schools, including Bethel, North Thurston, Olympia, and Timberline. Overall, Yelm is a mid-performing large school with solid literacy and science foundations, but math achievement, graduation trends, and special education outcomes deserve close attention.
