Summary:
ZIP code 80631, in the Greeley, Colorado area, contains just one middle school: Heath Middle School, which serves grades 6 through 8 and enrolls 499 students in Greeley School District No. 6. The district itself ranks in the bottom 16% of Colorado districts, and unfortunately Heath sits even lower within that context.
Heath is a high-poverty school, with more than 80% of students qualifying for free or reduced-price lunch, and its academic results lag far behind district and state averages. On the 2025–2026 CMAS tests, only 17.3% of students were proficient in English Language Arts, 12.3% in Math, and just 9.9% in 8th-grade Science—all roughly 25 points below the state. Proficiency is consistently low across every grade level: ELA hovers around 17% in grades 6, 7, and 8, while Math dips to 10.3% in 7th grade before rising slightly to 14.4% in 8th grade. Over the past three school years, Heath has ranked in the bottom 6–7% of Colorado middle schools, showing no meaningful improvement.
Perhaps the most pressing issue is chronic absenteeism. Nearly 44% of Heath students are chronically absent, compared with 34.6% for the district and 28.4% for the state. That means almost half of the student body is missing enough school to seriously impact learning. On a more positive note, the student-teacher ratio of 15.1 is moderate, so severe overcrowding is not part of the problem. For parents, the bottom line is that Heath faces major challenges driven by high poverty and low attendance, and those factors are closely tied to its persistently low test scores and bottom-tier state ranking.
