Calling all Part C and 619 Family Leaders! It takes teamwork to build effective state and local systems for young children with disabilities. You are an essential member of those teams, working in partnership with the other players. In this session, we will explore what effective teams look like and how they function. Family leaders will share with each other their roles within states and practical ways to support systems development. Together, we will review the IDIO Virtual Convening concurrent sessions and consider how families can most meaningfully share their voices in these sessions.
