Announcing an exciting new opportunity to build on and expand TACSEI work!

We are pleased to announce that some of the TACSEI staff will be working with the new OSEP funded Early Childhood Technical Assistance Center (ECTA Center) to assist states in their efforts to improve systems and services related to children with disabilities. This work will keep the Pyramid and TACSEI initiatives available as we continue to help states build their capacity to implement and scale-up evidence based practices including those to support childrenā??s social emotional competence. See Co-Director Lynne Kahn's announcement on the home page of the ECTA Centerā??s new website.

The Technical Assistance Center on Social Emotional Intervention for Young Children (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 immediately view, download and use.

TACSEI is a five-year grant made possible by the U.S. Department of Education, Office of Special Education Programs.
