101216.3 Teacher-Child Ratio (b) The licensee may use teacher aides in a teacher-child ratio of one teacher and one aide for every 15 children in attendance. This requirement is not met as evidenced by: Based on observation, interview, and record review, the facility did not comply with the section cited above during the staff breaks as there are two fully qualified teachers and one aide with no ECE units present supervising 25 children. During today's visit, LPA also observed 2 qualified teachers with 25 children in the outdoor area, while the aide is inside the facility prepping and cleaning. This poses a potential health, safety or personal rights risk to persons in care.
