CEITAN is the “home base” for the Early Start Comprehensive System of Personnel Development, a collaborative effort sponsored by the California Department of Developmental Services, planned in collaboration with the California Department of Education, and administered by the WestEd Center for Prevention and Early Intervention. Through multi-modal training and technical assistance, the Early Start Comprehensive System of Personnel Development delivers the knowledge and skills that ensure that early intervention professionals are qualified and that services to infants and toddlers with disabilities and their families are provided statewide in a coordinated and family-centered system.
