Summary:
Zip code 80504 is home to 9 elementary schools serving grades PK-5 and PK-8 across Longmont, Firestone, and Frederick, Colorado, all part of the St. Vrain Valley School District No. Re1J, a district ranked 23rd out of 115 in Colorado. With 4,172 students across the nine schools, the area offers a wide range of educational experiences, from small charters to large PK-8 campuses.
Standout schools are clearly identifiable. Fall River Elementary School is the strongest overall, ranking in the 81st percentile with the highest ELA (66.7%), math (57.7%), and among the best science proficiency (46.3%) in the area, while keeping chronic absenteeism low at 13.6%. Firestone Charter Academy is the top charter, ranking in the 62nd percentile, with the lowest chronic absenteeism (10.0%) and poverty rate (22.3%), plus strong ELA scores (59.6%). Alpine Elementary School and Legacy Elementary School are notable improvers, each jumping several hundred places in the state rankings. On the other end, Timberline Pk-8 and Rocky Mountain Elementary School rank in the bottom 11% of the state, with very low proficiency scores and high poverty rates above 80%.
The biggest takeaway is the vast achievement gap within this zip code. For example, ELA proficiency ranges from 66.7% at Fall River to just 16.6% at Timberline—a 50-point difference. Poverty and chronic absenteeism closely track these results, with high-poverty schools also seeing the worst attendance. Chronic absenteeism for the area is actually better than the state average, but it remains high at the lowest-performing schools. Science scores are volatile, as they test only 5th graders and can swing by 20 points from year to year. Interestingly, student-teacher ratio doesn't predict success: Carbon Valley Academy has the lowest ratio (11.7) but low scores. For parents, this area offers excellent choices at Fall River and Firestone, plus several upward-trending schools, but also highlights how much school quality can vary within a few miles.
