Summary:

In the Arlington, WA area (ZIP 98223), parents will find two public middle schools, Post Middle School and Haller Middle School, both serving grades 6-8 within the Arlington School District.

Comparing the two, Haller Middle School generally achieves higher academic rankings, with stronger performance in English Language Arts and notably better science scores that are close to the state average. Post Middle School operates with a slightly lower student-to-teacher ratio and higher per-student spending, yet its academic outcomes, particularly in 8th-grade English and science, lag behind its counterpart. Both schools have seen their statewide rankings decline over the past few years.

The most significant challenge for both middle schools is mathematics, where proficiency rates are well below both the district and state averages. This is a key area for potential improvement across the Arlington School District. Parents should note that while Haller shows a strong pattern of improvement in English scores from 6th to 8th grade, Post does not follow the same trend, which may reflect different academic support systems. Overall, the district is rated as average within the state, but these two middle schools currently perform below that district-wide standing.
