Summary:
Highline School District has five middle schools serving grades 6–8, with about 3,280 students total, and the schools show wide differences in academic performance, enrollment, staffing, and student needs.
Sylvester Middle School is the clear academic leader. It has the highest proficiency rates in English language arts, math, and science, at 42.73%, 33.77%, and 49.10%, respectively. Its science score is nearly equal to the state result, and its statewide ranking improved to 282nd of 514 schools, placing it in the 45th percentile. Sylvester also shows the most consistent results across grades. The other schools have more specific strengths: Chinook Middle School performs relatively well in science and has stronger eighth-grade ELA and math results, while Pacific Middle School also has comparatively strong eighth-grade results. Cascade Middle School has the lowest student-teacher ratio at 16.8 to 1 and performs better in sixth- and seventh-grade ELA and math than in eighth grade.
Glacier Middle School faces the greatest academic challenges, with the lowest all-grade proficiency rates: 16.00% in ELA, 9.49% in math, and 16.14% in science. Math is the broadest concern across the group, since it is every school’s weakest subject and remains below the state rate even at Sylvester. Four schools have free- or reduced-price lunch rates above 70%, while Sylvester’s rate is 49.48%, so families should consider each school’s student needs and context when comparing results. All five schools improved their numerical statewide ranking from the previous year, although Sylvester remains far ahead of the others.
