The report examines the need for an outreach program to alert families of low-income handicapped children (from birth through 18 years old) to assistance available under the Social Security Administration's Supplemental Security Income (SSI) program. In an introductory section, it is explained that unknown numbers of SSI-eligible children are not receiving benefits; and a model program to facilitate early identification, correct diagnosis, enrollment, and service delivery is proposed. Discussed in section 2 are feasibility issues related to alerting SSI-eligible children, using volunteers in a model outreach program, and evaluating the effectiveness of SSI operations. Presented in section 3 is a detailed description of the proposed demonstration project, including such design as initial organization, training staff coordinators and volunteers, preparing publicity materials, and project operations related to outreach, escort service and data collection. Sections 4 and 5 deal with criteria for recommending Atlanta, Georgia as a demonstration site and with staff and budgetary considerations. Included in the appendixes are lists of member agencies of the National Council of Organizations for Children and Youth and of persons interviewed concerning the demonstration project. (LH)
