Summary

Carbon Valley Academy is a public charter elementary and middle school serving 250 students in grades PK-8 in Frederick, Colorado, which is part of the St. Vrain Valley School District. While the district is ranked 27th out of 115 districts in the state and has a 4-star rating, Carbon Valley Academy has consistently underperformed compared to the district and state averages on standardized tests.

In the 2024-2025 school year, only 21% of all grades at Carbon Valley Academy were proficient or better in English Language Arts, compared to 50.9% for the district and 44.8% for the state. The school's performance has been particularly low in Math, with only 25% of all grades proficient or better, compared to 45.4% for the district and 35.9% for the state. Additionally, the school's 5th grade Science proficiency rate of 26.3% was significantly below the district's 44.3% and the state's 39%.

Carbon Valley Academy's academic struggles are reflected in its statewide ranking, which has declined over the years and currently places it in the bottom half of Colorado elementary schools, with a 1-star rating from SchoolDigger. While the nearby Highlands Elementary, Soaring Heights PK-8, and Prairie Ridge Elementary schools generally outperform Carbon Valley Academy, the school also faces challenges with high dropout rates and chronic absenteeism, suggesting the need for targeted interventions to improve the educational outcomes for its students.
