WWC Summary of Evidence for this Intervention
Play-Based Interventions
Play-based interventions are practices designed to improve socio-emotional, physical, language, and cognitive development through guided interactive play. During play sessions, an interventionist uses strategies including modeling, verbal redirection, reinforcement, and indirect instruction to sustain and encourage child play activities. Through the use of appropriate play materials and the direction of the interventionist, the goal is for young children with disabilities to be better able to explore, experiment, interact, and express themselves.
April 2012
As of April 2012, no studies of Play-Based Interventions were found that fell within the
scope of the Early Childhood Education for Children with Disabilities review protocol and met WWC evidence standards.
Therefore, the WWC is unable to draw any research based conclusions
about the effectiveness or ineffectiveness of Play-Based Interventions to improve outcomes in this area.

An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
The indicator represents the highest level of similarity found between your students and each of the high-quality studies of the intervention. Three filled in ovals indicates that at least one study that met standards was conducted on students very similar to yours. Clicking on the indicator for a study will provide information on the similarity for each of the characteristics you selected.
