Welcome to TACSEI
The Technical Assistance Center on Social Emotional Intervention for Young Children, also known as TACSEI, is a five-year grant made possible by the U.S. Department of Education, Office of Special Education Programs. TACSEI takes the research that shows which practices improve the social-emotional outcomes for young children with, or at risk for, delays or disabilities and creates FREE products and resources to help decision makers, caregivers, and service providers apply these best practices in the work they do every day. Most of these free products are available right here on our website for you to view, download and use.
The conceptual model TACSEI uses to deliver this important information is the widely endorsed Pyramid Model framework that was created to promote social-emotional competence and address challenging behavior. For more information about the Pyramid Model as well as many other valuable resources, please visit our partner website, the Center on the Social and Emotional Foundations for Early Learning (CSEFEL).
