Summary

Thunder Valley Pk-8 is a public elementary school located in Frederick, Colorado, serving grades PK-8 with 857 students. The school is part of the St. Vrain Valley School District, which is ranked 27th out of 115 districts in Colorado and has a 4-star rating.

Despite being part of a generally high-performing district, Thunder Valley Pk-8 consistently ranks in the bottom 20% of Colorado elementary schools, with a 1-star rating from SchoolDigger. The school's proficiency rates in CMAS (Colorado Measures of Academic Success) tests are significantly lower than the district and state averages across all grades and subjects. For example, in 2024-2025, the school's proficiency rates were 18.4% in science (5th grade), 22% in ELA (all grades), and 15.4% in math (all grades), compared to the district averages of 44.3%, 50.9%, and 45.4%, respectively.

The school's challenges may be partly attributed to its higher percentage of students from low socioeconomic backgrounds, with 57.06% of students qualifying for free or reduced-price lunch in 2023-2024. Additionally, Thunder Valley Pk-8 has significantly higher chronic absenteeism rates, reaching 27.7% in 2023-2024, and higher dropout rates than the district and state averages. In comparison, nearby schools such as Soaring Heights Pk-8, Firestone Charter Academy, and Grand View Elementary generally perform better academically and have lower percentages of students from low socioeconomic backgrounds and lower chronic absenteeism rates.

Great teachers our child went for kindergarten and first grade. He enjoyed them and we appreciate the teachers willingness to help us know what was going on. the only problem we had was when there was some political and social views talked about in class that caused for some interesting conversation at home. I believe opinion should not be discussed as fact to a room of 7 year old kids. Close Quote
