Summary

Monarch High School is a large public high school in Louisville, Colorado, serving roughly 1,431 students in grades 9–12 as part of the Boulder Valley School District No. Re2, one of Colorado's highest-rated districts (5 stars, 96th percentile). Monarch itself ranks 22nd out of 338 Colorado high schools (93rd percentile, 5 stars) in 2025–2026. It comfortably outperforms nearby traditional public high schools like Centaurus High School, Broomfield High School, Legacy High School, and Standley Lake High School, though it trails Fairview High School and Jefferson Academy Secondary at the very top of the regional rankings.

Monarch's academic profile is strong across the board, with reading and writing as a clear standout. On the 2025–2026 SAT, 87% of 11th graders were proficient in Reading & Writing versus 60% statewide, and 9th grade PSAT reading proficiency was an impressive 90%. Math is solid, running roughly 25–30 percentage points above state averages, but it remains the main gap to the state's elite: 61% of Monarch 11th graders scored proficient on SAT Math versus 71% at Fairview. Science is a genuine highlight: Monarch's 65.9% CMAS proficiency rate was the highest among all nearby schools and more than double the state average. Graduation rates have held steadily in the 95–98% range, with an exceptionally low dropout rate (0.1%–0.6%).

Monarch's most unique strength is its work with students with disabilities: the school ranked 3rd out of 55 Colorado high schools in this area, a national-caliber result that sets it apart from most peers. The main areas to watch are chronic absenteeism, which rose from 15.8% to 18.2% and now sits above the district average of 17.5%, and the student-teacher ratio of 22.2, which is on the higher side yet has not prevented excellent outcomes. There is also some year-over-year variability in results for low-income and multi-racial students, which may reflect small group sizes. Monarch's trajectory — from the 76th percentile in 2015–2016 to a top-25 mainstay today — makes it one of the district's most compelling success stories.

What people are saying

by a parent
Thursday, August 16, 2018

I sent my child to Monarch for a couple of years before moving them out of there. The teachers spend a large portion of their time complaining about the current political state of affairs than they do teaching the students. Showing videos from cable late night shows where the host is dropping F bombs left and right is not something I imagined they would be doing at any school but apparently, it is ok at Monarch. My student would have a difficult time avoiding the issues that plague this school. Drugs, vaping and alcohol have been staples that this school has been known for. The police routinely respond to this school on these issues as well as teachers being involved in inappropriate situations with students. I know the former SRO at this school and the stories from her are appalling. This is a very affluent (or so they think) community where money and social status takes precedent over the students academics. We have friends that currently work for the Boulder Valley School District. They had also moved their kids out of Monarch over a decade ago for the same issues and problems. Those kids have excelled and have gone on to wonderful careers with beautiful families. It is unfortunate, but we are glad to have left that school for a better environment for our child.
