Summary

Addenbrooke Classical Academy is a small public high school in Lakewood, Colorado, serving 191 students in grades 9–12 within the Jefferson County School District R-1, a district ranked in the top quarter of Colorado. The school currently sits at 166th out of 338 high schools statewide (51st percentile, 3 stars) — a solid mid-tier ranking that has improved from earlier this decade. Its neighborhood is competitive and economically diverse, with D'Evelyn Junior/Senior High School — the #1 ranked high school in the state — just two miles away, along with Bear Creek High School and several Denver-area schools.

Addenbrooke's greatest strengths are student engagement and literacy. The school boasts a low student-teacher ratio of 12.2:1, chronic absenteeism of 25.4% (better than most nearby schools), a dropout rate near zero, and graduation rates consistently above 90% — well above the state average. Reading and writing scores match or exceed state proficiency levels, with 77% of 9th graders proficient in PSAT9 Reading/Writing. However, math and science are clear weaknesses: only 11% of 11th graders were proficient in SAT Math and 17.1% in Science, far below district and state averages. By comparison, D'Evelyn's 11th graders scored 96% in SAT Math.

One of the school's most notable dynamics is a gender gap in outcomes. In 2025-2026, male students ranked at the 73rd percentile statewide for boys, while female students ranked at only the 43rd percentile for girls — a gap that was even wider the previous year (80th vs. 26th percentile). Given the small enrollment, families should watch whether this reflects a specific cohort or a systematic issue. Overall, Addenbrooke is a small, well-attended school with strong graduation outcomes and solid literacy, but significant STEM challenges. It outperforms most Denver-area neighbors, is comparable to Bear Creek High School, but remains far behind the exceptional results at D'Evelyn.
