This four-page fact sheet provides an overview of the Pyramid Model for Supporting Social Emotional Competence in Infants and Young Children. Specifically, this fact sheet describes the three tiers of intervention practice: universal promotion for all children; secondary preventions to address the intervention needs for children at risk of social emotional delays, and tertiary interventions needed for children with persistent challenges. Additionally, six key assumptions that were made during the design process about how the Pyramid Model would be implemented are outlined.
