On August 5, 2026, Licensing Program Analysts (LPAs) Van and Cruz conducted an unannounced complaint investigation regarding the allegation that staff left a child outside of the child care center unsupervised. LPAs met with the director, Claudine Castillo, and explained the purpose of the visit. At the time of the inspection, five teachers and the director were supervising 23 children (13 preschoolers, 5 infants, and 6 toddlers). The center was operating within its licensed capacity and required teacher to infant ratio.

As part of the investigation, LPAs conducted interviews and reviewed relevant records and the facility’s unusual incident report. The center self reported the incident and provided police case number 260-427-109. Interviews with parties available confirmed that a child had been left outside the facility without supervision.

Based on the information gathered, the preponderance of evidence standard has been met; therefore, the above allegation is found to be SUBSTANTIATED. A $500 civil penalty was assessed today.

See LIC 9099D for a Type A deficiency cited today.
