Summary

Thunderridge High School is a large, comprehensive public high school in Highlands Ranch, Colorado, serving approximately 1,820 students in grades 9–12 as part of the Douglas County School District No. Re 1, a top-ranked 5-star district. For the 2025–2026 school year, Thunderridge High School ranked 45th out of 338 Colorado high schools (87th percentile, 4 stars), continuing a consistent pattern of top-quartile performance over the past several years. The school's most impressive numbers are its graduation and attendance outcomes: a 97.2% graduation rate versus 93.6% for the district and 85.6% statewide, a dropout rate of just 0.1%, and a chronic absenteeism rate of 13.0%—well below the district's 16.6% and less than half the state's 28.4%.

Academically, Thunderridge is strongest in reading and writing. SAT Reading/Writing proficiency stands at 82%, compared to 76% for the district and 60% statewide, and PSAT scores follow a similar pattern. Math is the school's relative weakness, with SAT math proficiency at 58% (still well above the state's 32%) and ninth-grade PSAT math proficiency at 57%, a notable drop from 68% the prior year. Science proficiency has been volatile, swinging from 34.4% in 2023–2024 to 56.1% in 2024–2025, then settling at 45.1% in 2025–2026. The school also performs strongly for historically underserved student groups: Hispanic students rank in the 84th percentile statewide, low-income students in the 87th percentile, and Gifted/Talented students in the 90th percentile.

Among nearby comprehensive high schools, Thunderridge compares favorably. It trails Rock Canyon High School (ranked 13th) and Mountain Vista High School (ranked 36th) in overall state ranking, but matches Rock Canyon on SAT math and posts much lower chronic absenteeism than Mountain Vista (13.0% vs. 20.1%). It clearly outpaces Highlands Ranch High School on nearly every metric, including graduation rate (97.2% vs. 94.8%) and chronic absenteeism (13.0% vs. 22.8%). Against Arapahoe High School and Heritage High School in the Littleton area, Thunderridge posts a higher graduation rate than both and far lower chronic absenteeism. Overall, Thunderridge is a top-tier comprehensive high school whose greatest strengths are near-universal graduation, strong literacy results, and broad-based success across student subgroups. Its areas to watch are ninth-grade math proficiency, science score volatility, and declining relative performance for multi-racial and disabled students.
