Summary:

The St. Vrain Valley School District No. Re1J includes 53 schools serving roughly 31,300 students in Colorado's Boulder and Weld counties, spanning 33 elementary schools, 8 middle schools, 10 high schools, and 2 alternative programs from preschool through 12th grade. The district ranks 23rd of 115 Colorado districts (80th percentile, 4 stars) and consistently exceeds state averages, with a 96.8% graduation rate versus 85.6% statewide, chronic absenteeism of 23.1% versus 28.4%, and CMAS ELA and math proficiency of 51.0% and 46.9% compared to state rates of 44.7% and 37.3%.

The standout schools are among the best in Colorado. Lyons Elementary School ranks 20th of 943 elementary schools (98th percentile) with 85.6% ELA and 74.1% math proficiency, followed closely by Hygiene Elementary School (96th percentile), Niwot Elementary School (96th percentile; just 6.0% chronic absenteeism), Blue Mountain Elementary (94th percentile), and Erie Elementary School (94th percentile). Among middle schools, Altona Middle School leads at the 96th percentile, with Mead Middle School (87th) and Westview Middle School (83rd) also strong. At the high school level, Niwot High School (91st percentile) posts 81% SAT reading/writing and 51% math, while Lyons Middle/Senior High School (88th), Erie High School (83rd), and Silver Creek High School (80th) all have graduation rates above 97%.

There are bright spots and challenges. Mountain View Elementary School is a genuine success story, jumping from the 13th to 49th percentile in two years with ELA proficiency rising from 24.6% to 37.0% and math climbing from 20.2% to 41.3%. However, Skyline High School (20th percentile) and New Meridian High School struggle with chronic absenteeism above 48%, and Northridge Elementary School (6th percentile) posts just 12.5% ELA and 18.3% math proficiency. Across the district, math lags reading at every level, and high school science proficiency is under 50% almost everywhere, suggesting these are the highest-leverage areas for improvement.
