Summary

Lasley Elementary School in Lakewood, CO, serves about 576 students in grades K-6 and is part of the Jefferson County School District No. R-1—a district that performs well overall in Colorado, yet Lasley itself is one of the lowest-performing elementary schools in the state, ranking in the 7th percentile with a 0-star rating. Roughly 76–81% of students qualify for free or reduced-price lunch, and the school serves a concentrated pocket of disadvantage despite sitting inside a high-performing district.

The most urgent issue at Lasley is chronic absenteeism: 49.5% of students were chronically absent in 2024–2025, nearly double the district rate and the highest among all nearby schools. Academic results are critically low—just 19.6% of students are proficient in English Language Arts and 9.2% in math, scores that trail district averages by 34–35 points. By comparison, Green Gables Elementary School, only 1.7 miles away, has just 15% chronic absenteeism and proficiency rates two to four times higher. Even within its own district cluster, Lasley outperforms only Deane Elementary School, while Patterson International School posts math proficiency nearly three times higher and Rose Stein International Elementary posts math proficiency roughly 50% higher.

Lasley’s decline accelerated after the pandemic and has not reversed. The school fell from the 41st percentile in 2018–2019 to the bottom 5% in 2024–2025 and 2025–2026. Every student subgroup—female, male, Hispanic, and low-income—scores in the bottom 1st–6th percentile statewide, indicating system-wide struggles rather than a single issue. Nearby schools with similar poverty levels, such as Doull Elementary School, have shown recovery is possible with 47.4% ELA proficiency despite high poverty rates. At 15.1:1, Lasley’s student-teacher ratio is similar to neighbors, so the problems appear tied more to attendance and instructional support than to class size alone.
