Summary

Mammoth Heights Elementary is a PK–6 public school in Parker, CO, serving 598 students as part of Douglas County School District No. Re 1, which ranks 6th out of 115 districts statewide. The school itself ranks 206th out of 943 Colorado elementary schools, placing it in the 78th percentile with a 4-star rating. That makes Mammoth Heights a solidly above-average school with a genuine turnaround story: a decade ago it sat in the bottom half of state rankings, and it has now spent three consecutive years in the top quarter.

Academically, Mammoth Heights posts proficiency rates close to the district average in both ELA (62.1%) and math (55.6%), and well above the state averages of 44.7% and 37.3%. However, the school is surrounded by some of Colorado's highest-performing elementary schools. Within a few miles, Parker Core Knowledge, Gold Rush Elementary, Challenge to Excellence, Prairie Crossing, and North Star Academy all rank in the top 50 statewide, with ELA proficiency as high as 89.8%. Mammoth's most significant academic weakness is 5th-grade science, where just 40.3% of students are proficient compared to the district's 55.0%. Grade-level math also reveals a puzzling pattern: 6th-grade math exceeds the district by nearly 13 points, while 4th- and 5th-grade math run about 11 points below district averages.

Mammoth Heights also stands out demographically. Its free/reduced lunch population has risen from 17.7% to 27.8% over three years, yet the school has continued to improve. Subgroup results are a notable strength: Hispanic students and students from low-socioeconomic backgrounds perform well above their statewide peers. The chronic absenteeism rate of 18.0% has improved from 20.9% but remains above the district average and well above the single-digit rates at nearby top schools. Overall, Mammoth Heights is an improving school serving a more economically diverse population than its elite neighbors. If it can shore up science and middle-grade math while continuing to reduce absenteeism, the school has strong momentum to climb even higher in the years ahead.
