The purpose of this study was to gather information about the different types of home visiting services provided to families of at-risk children, with a special emphasis on the home visiting option within the Head Start program. A 13-page questionnaire was sent to 4,162 organizations nationwide that operated home visiting programs. Responses were received from 1,904 of these organizations. The questionnaire surveyed 12 areas: (1) program affiliation; (2) population served; (3) child and parent characteristics; (4) purposes of the program; (5) coordination of services; (6) funding; (7) specific services provided; (8) delivery models for home visits; (9) curriculum for home visiting services; (10) home visitor employment and training; (11) supervision of home visitors; and (12) evaluation strategies. Survey results indicated that 304 programs identified themselves as being associated with Head Start. Compared to other home visiting programs affiliated with health, educational, and social services, Head Start home visiting options possessed a more focused intervention strategy and were more focused on the population they served, the services they saw as important, and the providers of those services. Head Start home visiting options exhibited problems in the areas of efficacy, training, and coordination. Contains 16 references. (MDM)
