A chapter on the service needs of migrant children focuses on the areas of greatest need in education, social services, and health care. Service delivery issues include gaps in service delivery, possible models for coordination of services, barriers to successful service coordination, and factors facilitating coordination. Features of an ideal program of service coordination are listed.
