Summary

Mary E Pennock Elementary School is a PK–5 public elementary school in Brighton, CO, serving 592 students in School District 27J. The school earns a 2-star rating and ranks in the 38th percentile statewide, placing it in the upper-middle tier of neighborhood elementary schools in Brighton. With about 60% of students qualifying for free/reduced lunch, Pennock faces economic challenges, yet it outperforms its district in both English Language Arts and math. The student-teacher ratio improved to 15.7, a positive sign for individual attention.

Pennock's math performance stands out. In 2024-2025, math proficiency exceeded the state average — uncommon for a school with this poverty level — and in 2025-2026 the school still led its district by nearly 7 points. Fourth grade is a bright spot, with ELA proficiency at 52.6%, well above both district and state averages. The school also serves Hispanic students notably well, ranking in the 56th percentile statewide for that group, a strong upward trend over the past few years. Compared to nearby schools, Pennock outperforms Henderson Elementary, Bromley East Charter School, and Southeast Elementary, though it trails Reunion Elementary, Foundations Academy, and Elaine S. Padilla Elementary.

The biggest challenges are early-grade literacy, science, chronic absenteeism, and support for high-ability students. Only 24.2% of third graders are proficient in ELA, and fifth-grade science sits at 22.9%, well below the state's 36.1%. Chronic absenteeism of 29.0% is close to district and state averages but far above higher-performing neighbors like Reunion. Most concerning, the school's Gifted and Talented students have ranked at the 1st percentile statewide for three straight years. Reducing absenteeism and replicating the 4th-grade success schoolwide would give Pennock clear potential to move toward the upper half of Colorado elementary schools.
