Summary

Flagstaff Charter Academy is a PK-8 charter school in Longmont, CO, serving about 725 students and operating as part of the St. Vrain Valley School District. The school currently holds a 3-star rating, ranking 330th of 943 Colorado schools (65th percentile), and while it comfortably beats district and state averages in both ELA and math, it is not among the top-performing local options. For instance, Niwot Elementary School posts much higher proficiency rates (76.7% ELA, 70.9% math), as do Blue Mountain Elementary and Central Elementary School.

Flagstaff’s clearest strength is its 8th-grade performance. In 8th grade, ELA proficiency reaches 77.3% versus the district’s 47.1%, math 64.7% versus 48.5%, and science 62.1% versus 40.8% — an exceptional gap of 21.3 points. However, the school shows a pronounced dip in 6th grade, particularly in math, where only 30.6% of students are proficient compared to the district’s 39.3%. Science also tells a split story: strong and consistent at 8th grade, but inconsistent at 5th grade (ranging from 38-50% over recent years). This suggests the PK-8 model works well by the end, but the transition into middle school is a fragile point.

Flagstaff benefits from a relatively low poverty rate (19.45% free/reduced lunch) and better attendance than the district, with a chronic absenteeism rate of 17.9% versus the district’s 23.1%. Its student-teacher ratio of 13.1 is also favorable. Yet the school’s state ranking has declined over the past decade, from the 84th percentile in 2015-16 to the 65th percentile now. For parents, Flagstaff offers a stable, above-average educational experience with a unique single-building PK-8 pathway, but families seeking the highest test scores in the area may find stronger options at Niwot Elementary School or Central Elementary School.

The school absolutely doesn’t care about kids who have some difficulties. My son started preschool and was one of the youngest in his class and didn’t go to day care before. They didn’t do a single thing to help him. We got complaints like he is not able to put his bag properly. They even let me and my wife sit in the class for the whole duration of class so that we can work on these things. We took him out and sent him to public school and he is doing much better. The school only cares about their rating. I wouldn’t send my kids to this school and would advice other parents to think twice Close Quote

Math and reading are remedial. Your child will end fourth free doing a"book in a bag" report instead of the five paragraph book reports completed in the local public school 4th grade. The way the math classes are structured will leave children feeling they are unworthy of higher level math. Ask questions, do your research. Ask questions esp. About changes in math and reading curriculum over the past 5 years and why the school no longer receives the John Irwin award. Close Quote

Teachers and Administration are extremely condescending and rude! Time to say bye-bye to Flagstaff!! They don't let children be children....they want to control them and medicate them. They are constantly sending home "Codes of Contact" for ridiculous things.....sooooo much paper wasted there on a daily basis! Teachers and Administration cannot handle anything other than sitting on their butts. They want to complain to the parents and expect the parents to handle what they should be handling in the classroom. Adios Flagstaff! Close Quote

Virtually nonexistent anti-bullying policy, and special ed. department.
Many of the administrators, teachers & "specialists" were very condescending and disrespectful to our daughter.
I wish we would've recognized what was going on there sooner, but we put our child through four awful years at this place before finally acknowledging it was a colossal failure for our family. Close Quote
