Better than 17% of Colorado elementary schools

Summary

Twombly Elementary School, part of Weld Re-8 Schools, serves roughly 473 students in grades K–5 in Fort Lupton, Colorado, where about 65% of students qualify for free/reduced lunch. The school has historically ranked in the lower fifth of Colorado elementary schools, most recently placing at the 17th percentile with a 1-star rating. However, the overall rating masks some notable strengths.

Math is a clear bright spot. All-grades math proficiency sits at 27.0%, above the district average of 21.6% and higher than several nearby schools, including Leo William Butler Elementary School (22.7%), Thunder Valley Pk-8 (22.4%), and South Elementary School (15.0%). In 3rd grade, 38.1% of students are proficient in math, nearly matching the state average of 41.5%. Attendance is another positive: the 23.8% chronic absenteeism rate is well below the district's 33.1% and the state's 28.4%, and it improved meaningfully from the previous year. The school also earns relatively strong marks for its low-income students, who perform near the statewide median (46th percentile) — far better than the school's overall ranking would suggest.

The biggest challenges are in English Language Arts and science. Only 17.8% of students are proficient in ELA, compared with 44.7% statewide, and 4th grade ELA proficiency sits at just 11.1%. Science has also trended downward, falling to 13.8% proficiency. Notably, math performance drops off sharply after 3rd grade — from 38.1% proficiency to 14.3% in 4th grade — suggesting a transition challenge that could be addressed. Compared with Leo William Butler Elementary School, a nearby school in the same district with nearly identical demographics, Twombly outperforms in math but trails in ELA, science, and attendance. Overall, Twombly's path forward likely involves building on its early-grade math success and extending that momentum to ELA, science, and upper elementary grades.
