Summary

Post Middle School is a public school in Arlington, Washington, serving grades 6–8 and 645 students as part of the Arlington School District. It is a mid-performing school in the state, ranking 251st of 514 Washington middle schools, at the 51st percentile, with a three-star rating. The school’s latest results show meaningful improvement, although performance remains uneven across subjects and grades.

Post’s strongest academic area is English Language Arts, where 50.4% of students were proficient in 2025–2026, close to the statewide rate of 52.81%. Math was weaker at 32.01%, compared with 43.11% statewide, while science reached 44.67%. Results improved in every subject from the prior year, with science making the largest gain of 11.17 percentage points. Grade-level results point to a particular concern in eighth-grade math: just 23.12% of students were proficient, compared with 34.08% in sixth grade and 38.54% in seventh grade. By contrast, eighth-grade ELA was a bright spot at 54%, above the state’s eighth-grade rate.

Post is located only 0.56 miles from Haller Middle School, its closest same-district comparison, and currently performs better there in ELA, math, and science. However, Port Susan Middle School and North Lake Middle School have substantially higher proficiency, especially in math. Stanwood Middle School is a useful similar-size comparison: the schools were nearly tied in ELA, but Stanwood was stronger in math and science. Overall, Post appears to be gaining momentum, with math—especially eighth grade—and support for students in special education remaining the clearest priorities.
