Summary:
Zip code 80108, covering the Castle Pines and Castle Rock area, contains five elementary schools serving approximately 4,806 students, all part of Douglas County School District No. Re 1, a 5-star district ranked 6th out of 115 in Colorado. All five schools rank above the state average, with three landing in the top 10% statewide, making this one of the strongest educational areas in Colorado.
Timber Trail Elementary School is the clear standout, ranking #33 in the state (97th percentile) with a 5-star rating, the highest ELA proficiency at 78.4%, highest math proficiency at 74.9%, and the lowest chronic absenteeism at 5.8%. Buffalo Ridge Elementary School is close behind at #45 (95th percentile) with a 5-star rating and has been steadily improving, rising from #95 to #45 over the past two years — impressive given it has the highest free/reduced lunch rate in the group. American Academy is a massive PK-8 school with 2,803 students, more than five times the size of its peers, yet still ranks #85 (91st percentile) with strong middle-school ELA and science results.
Sage Canyon Elementary ranks #173 (82nd percentile) with a 4-star rating, posting solid but less elite scores, with a notable 5th-grade dip in math and science. DC Montessori Charter School is the lowest-ranked at #381 (60th percentile) with a 3-star rating, and math proficiency of 40.2% is a concern — barely above the state average — although its 8th-grade science scores were excellent. Chronic absenteeism tracks closely with performance: the top schools are around 6% while the lower-ranked schools are near 16%. With no standalone middle or high schools in the zip code, families relying on neighborhood schools will need to consider the two PK-8 options or look beyond 80108 for upper grades.
