ALLEGATION(S): - Staff do not keep the facility clean - Staff allow children to eat from the floor INVESTIGATION FINDINGS: Licensing Program Analyst (LPA) Marie Rodriguez conducted an unannounced inspection to open a complaint. LPA met with Teacher S.B. and explained purpose of inspection. Executive Director J.M. and Director S.N. arrived a short time later. Present at the school were the directors, 3 teachers, and 8 infants. During the course of the investigation, LPA conducted a physical plant tour of the facility and conducted interviews. LPA observed the school and the infant classroom to be clean and in good repair. Infant classroom is in a separate building from the school's preschool program. Per infant staff, children stay in the infant classroom during the school day and never go into the school's multi-purpose room. Per the Executive Director and Director, the school is cleaned throughout the day by staff and a cleaning crew deep cleans the school on Friday evenings. Based on the information gathered, there is insufficient evidence to prove the staff do not keep the facility cleaned and allow the children to eat from the floor.
