Summary

John W Thimmig Elementary School is a PK–5 school in Henderson, CO, serving 531 students within School District 27J, and it currently ranks 716th out of 943 Colorado elementary schools with a 1-star rating. The school's performance has been uneven but consistently low, falling from the 45th percentile in 2022–2023 to the 24th percentile in 2025–2026.

The school's biggest academic concern is math. Only 20.8% of students are proficient in math, compared with 26.8% for the district and 37.3% statewide—the lowest math proficiency among all nearby schools. Math has dropped sharply from 36.5% in 2022–2023. Reading, by contrast, is closer to district norms at 33.9% proficiency versus 34.2% for the district. Science is also weak at 18.0% proficiency. Chronic absenteeism affects 31.9% of students, above the state average of 28.4%, and the free/reduced lunch rate has climbed to 55.9%.

Compared with nearby schools, Thimmig sits in a lower-performing cluster alongside Henderson Elementary School, Turnberry Elementary, and Second Creek Elementary School—all of which share similar poverty and attendance challenges. Higher-performing neighbors like Landmark Academy at Reunion, Reunion Elementary School, West Ridge Elementary, and Brantner Elementary School have notably lower absenteeism and poverty. Belle Creek Charter School, with similar poverty levels, outperforms Thimmig in math and science, suggesting targeted instruction and attendance support will be key to reversing the school's trajectory.
