Enrollment in 2024-25 School Year: 880 students welcomed in Thunder Valley PK-8
Among the student body, 51.3% were girls and 48.7% were boys.
Data also showed that most of the students were Hispanic or Latino (542), representing 61.6% of the Thunder Valley PK-8 total enrollment. White students comprised the second-largest ethnic group, with 280 students (31.8%).
The grade level with the highest enrollment was fourth grade, with 106 students enrolled that year, accounting for 12% of the total student body.
The school is located in St. Vrain Valley School District No. Re1J, and has a central office in Frederick.
In total, there were 881,065 students enrolled in Colorado during the 2024-25 school year.
Colorado’s K–12 enrollment has gradually declined each year since the pandemic, with about 3–4% fewer students in 2024 than the state’s peak enrollment in 2019.
The declines are concentrated in the early grades and certain rural areas, while some metro districts are holding steady or growing. Lower birth rates and pandemic disruptions are driving the trend. Colorado’s public schools are now serving the smallest number of students in a decade, a shift that has implications for funding and planning even as per-pupil resources increase to compensate.
Colorado’s teacher workforce faces persistent shortages and pay challenges. In the 2023–24 school year, nearly 7,000 teaching positions were vacant statewide at some point. Districts managed to fill only about 75% of those openings with fully qualified hires, leaving many to be filled by short-term substitutes, retirees, or emergency credentials for the rest, while 9% remained unfilled for the entire school year.
