Summary
Challenge School is a mid-sized PK-8 school in Denver, CO, serving 560 students in the Cherry Creek School District No. 5, and it ranks among the very best schools in Colorado — 6th out of 943 schools in 2025-2026, placing it in the 99th percentile with a 5-star rating. This is no flash in the pan: Challenge has ranked in the top 11 schools statewide every year for a decade, earning 5 stars for ten consecutive reporting years. Test scores are extraordinary — 91.4% proficient in ELA and 92.2% in math, roughly double the district average and over 40 percentage points above the state average. Science proficiency is similarly strong, hitting 86.6% in 8th grade.
The contrast with nearby schools is staggering. Within a two-mile radius, most schools — including Denver Green School Southeast, Lowry Elementary School, Place Bridge Academy, and Virginia Court Elementary School — rank in the bottom 10-30% of Colorado, with ELA proficiency in the low teens. Challenge's nearest neighbors, such as Highline Community Elementary School, Village East Community Elementary School, and Ponderosa Elementary School, sit in the 3rd through 8th percentile statewide. Even the strongest nearby performer, Rocky Mountain Prep Creekside (66th percentile), posts math proficiency around half of Challenge's rate.
Part of the story is demographic: Challenge serves a much more affluent population (17.3% free/reduced lunch) than any nearby school, where poverty rates range from 65% to over 90%. Chronic absenteeism tells a similar tale — just 6.8% at Challenge versus 31-48% nearby. That said, Challenge's student-teacher ratio of 16.1 is on par with the area, suggesting its success comes from a combination of family background, school culture, and instructional practices. The school's one relative weakness is its Gifted and Talented subgroup, which ranked in just the 28th percentile statewide in 2025-2026 — worth asking about if your child is a high-achieving student. Overall, Challenge School is a consistently elite academic environment and, for most families, an exceptional choice.
