This paper describes a cross-agency model of training and technical assistance which prepares preschool teachers, therapists, social workers, drug treatment providers, parents, administrators, service coordinators, and bureaucrats to work with and understand children and families affected by alcohol and other drugs. Presented first is a brief background of the program, the Family Focused Early Intervention System (FFEIS). The program uses consultants to serve both as advisors and liaisons to regional and state authorities. Consultants who specialize in the areas of inclusion, developmentally appropriate practices, assistive technology for babies, toddlers, and preschoolers, and programs for children and families affected by alcohol and drugs. Additionally, data from various hospitals, agencies, and state and local health departments were analyzed with an eye toward social diagnosis, epidemiological diagnosis, educational and organizational diagnosis, and administrative and policy diagnosis. Data analysis revealed that the development of strong linkages between community early intervention providers, alcohol and drug treatment programs, health care providers, and public education activities was necessary to enable a seamless system of referral activity and services. It is also argued that pupil services personnel in schools can enhance these kinds of programs. Schools at both the building level and the district level must be more attuned to the needs of children and families affected by alcohol and other drugs. Contains three references. (RJM)
