Summary

Longmont High School is a comprehensive public high school in Longmont, Colorado, serving 1,268 students in grades 9–12 as part of the St. Vrain Valley School District. The school currently holds a 3-star rating and ranks 135th out of 338 Colorado high schools (60th percentile), a steady improvement from the 51st percentile in 2022–2023. It serves a considerably more economically diverse student body than nearby higher-ranked schools — nearly 48% of students qualify for free or reduced-price lunch, compared with roughly a quarter at Mead High School and Silver Creek High School.

Where Longmont High School truly stands out is in graduation and science. The school posts a 97.5% graduation rate — well above the state average of 85.6% — and a dropout rate of just 0.8%, half the state average. Its 11th-grade science proficiency rate is 42.7%, far exceeding the district (30.9%) and state (24.8%) averages and besting nearby Silver Creek High School (40.0%), Niwot High School (39.4%), and Erie High School (32.4%). SAT math (40%) also tops the district (38%) and state (32%), though PSAT 9 and 10 scores trail district averages, suggesting younger students may need additional support in math and literacy.

The school's most pressing challenge is chronic absenteeism, which stands at 42.1% — nearly double the district average of 23.1% and well above most area schools like Mead High School (21.3%) and Silver Creek High School (28.3%). This is a surprising contrast with the school's high graduation rate, suggesting many students are completing school despite missing substantial instructional time. Longmont High School is clearly improving and outperforms schools with similar poverty levels, such as Skyline High School, in nearly every subject. However, reading and writing scores remain below the district (62% vs. 66% on SAT Reading/Writing), and there is room to grow in supporting economically disadvantaged students, whose outcomes currently trail those of their peers.
