Sunset Middle School

Sunset Middle School is a mid-sized public middle school in Longmont, Colorado, serving 316 students in grades 6–8 as part of the St. Vrain Valley School District, rated 4 stars and ranked 23rd among Colorado districts. Despite the district's reputation, Sunset is a 2-star school ranking 276th out of 469 Colorado middle schools (41st percentile). It serves a high-poverty population—58.5% of students qualified for free or reduced-price lunch—while maintaining a notably low student-teacher ratio of 12.5, among the lowest in the area.

Academically, Sunset scores well below district and state averages across all subjects. In the 2025–2026 CMAS assessments, 33.2% of students were proficient in English Language Arts (vs. 51.0% district, 44.7% state), 28.5% in Math (vs. 46.9% district, 37.3% state), and 27.6% in 8th-grade Science. Math has improved for three consecutive years—from 19.4% to 28.5%—but a 7th-grade dip to 23.5% proficiency shows the gains are uneven. ELA dropped to 33.2% after a much stronger 43.9% the prior year.

The most defining feature of Sunset is its equity gap: low-income students rank at the 16th percentile statewide, a result nearly unchanged for three years, while more advantaged students at the school perform well above the state median. Among Longmont's high-poverty middle schools, Sunset performs slightly above Trail Ridge Middle School (39th percentile) and far above Longs Peak Middle School (10th percentile). Yet the contrast with Altona Middle School, just 2.2 miles away, is stark—Altona ranks in the 96th percentile with 5 stars. Both schools share the same district but serve very different student populations. With small class sizes already in place, the path forward likely involves addressing chronic absenteeism—currently 27%—and ensuring effective instruction reaches all students, especially those from low-income backgrounds.
