Summary

Lumberg Elementary School is a PK–6 school in Edgewater, Colorado, serving 526 students as part of Jefferson County School District R-1 — a district that ranks in the 79th percentile statewide, yet Lumberg itself sits at the very bottom of Colorado’s elementary school rankings, placing 942nd out of 943 schools for 2025–2026.

Academically, Lumberg’s proficiency rates are strikingly low. In English Language Arts, just 8% of students are proficient, compared with 53.7% across the district; in math, only 6.3% are proficient versus 44.6% districtwide. Nearby schools in the same district perform far better — Edgewater Elementary posts 26.7% ELA proficiency, Slater Elementary reaches 34.6%, and Jefferson County Open Elementary hits 44.9%. Even schools with similar poverty levels in other districts outperform Lumberg dramatically: Colfax Elementary, with 89.3% free/reduced lunch, achieves 33.3% ELA proficiency, while Rocky Mountain Prep Berkeley reaches 34.7% ELA and 30.8% math. Just two miles away, Edison Elementary posts 76.1% ELA and 72.4% math proficiency, showing how dramatically school-level outcomes can vary within a small area.

Chronic absenteeism is a defining challenge: 52.8% of Lumberg students were chronically absent in 2024–2025, roughly double the district and state rates, and up from 46.5% the prior year. The school also has a very high poverty concentration (85.4% free/reduced lunch) and a student-teacher ratio of 16.1 — higher than neighboring Eiber Elementary (13.1) and Stevens Elementary (13.0). This is not a one-year slump: Lumberg has ranked below the 15th percentile every year since at least 2014–2015, with math proficiency below 6.5% for three straight years. While poverty and attendance are real hurdles, the success of similar-poverty schools nearby suggests that focused efforts on attendance, instructional support, and school climate could meaningfully improve outcomes at Lumberg.
