Where this record comes from
The Department of Early Childhood keeps about three years of complaints on a program’s public page. Anything older is released only on request, as a single file covering the whole state. Shortlist asked for that file under the Colorado Open Records Act and renews it yearly; it is what this page shows for complaints older than the department’s own window.
The file this page is built from arrived on October 10, 2026 and covers complaints the department publishes today, and complaints back to January 2023 obtained by records request. The next request goes in October 2027.
The department publishes a report for each of these visits. Shortlist has not read those reports yet, so this page shows when the state came and not what it found.
Ask for this program’s record now
The department will also review one program’s complete file on request, which is more than either source above contains. Leave your email and Shortlist will ask for Cornerstone Montessori School’s file specifically, instead of waiting for the next one.
Shortlist replaces people’s names in the state’s text with initials. This is done by rule, not by hand, so it can miss a name or shorten a word that isn’t one. The state’s report, linked on each row, has the original.
Openings, child care subsidies, cost, hours and late pickup, ratios and staff, a typical day, and sick and biting policies aren’t on this page.
