Summary

Addenbrooke Classical Academy is a public charter high school located in Lakewood, Colorado, serving grades 9-12 with a student population of 189. The school is part of the Jefferson County School District No. R-1, which is ranked 29 out of 115 districts in Colorado and has a 4-star rating from SchoolDigger.

Addenbrooke Classical Academy has consistently underperformed compared to the district and state in standardized test scores, with only 15.4% of 11th-grade students proficient or better in CMAS/Science, compared to 34.7% for the district and 25% for the state. The school's performance on SAT and PSAT exams is also below the district and state averages. While the school's four-year graduation rate is on par with the district and state, its dropout rate is slightly higher. Additionally, Addenbrooke Classical Academy has experienced high rates of chronic absenteeism, ranging from 24.3% to 27.7% in recent years, significantly higher than the district and state averages.

Compared to nearby schools, such as D'Evelyn Junior/Senior High School, which consistently ranks among the top high schools in Colorado, and Bear Creek High School, Addenbrooke Classical Academy's academic performance is notably lower. The high rates of chronic absenteeism may be a contributing factor to the school's underperformance, and the school's student population composition, with a relatively low percentage of students eligible for free or reduced-price lunch, suggests that the school may not be serving a highly disadvantaged student population.
