One study of milieu teaching that falls within the scope of the Early Childhood Education Interventions for Children with Disabilities review protocol meets What Works Clearinghouse (WWC) evidence standards, and no studies meet WWC evidence standards with reservations. The one study included 40 preschool children with developmental delays (eligible for this topic area) attending two schools in Davidson County, Tennessee.
Based on this one study, the WWC considers the extent of evidence for milieu teaching on preschool children with disabilities to be small for communication/language competencies. Six other domains are not reported in this intervention report. (See the Effectiveness Summary for further description of all domains.)
