Designed for use by trainers in preparing unskilled workers with minimum education (at least fourth grade reading ability) for entry as nonprofessionals in human services, this manual is organized around the core of understanding of individual and group behavior and needs and of methods of interviewing or obtaining and recording information needed by all social service aides; it is intended as a basis for small group discussions occurring simultaneously with the specialty skill and on-the-job training components of the New Careers program. (An accompanying manual for trainees is also available.) The generic issues presented concern individual growth and development (practical skills including remediation and interviewing skills) and the individual and his relationship to work, people (human growth and development, human behavior and needs, communication skills, and group process), and the community (community structure, poverty, the Negro, law and society, and consumer education). The topics are accompanied by objectives, content outlines, and bibliographies. Also included are a glossary, explanation of the New Careers approach with suggestions for using the manual and for operating a program, training tips, and sections on field trips and development of attitudes and responsibilities. Appended are a basic bibliography and list of materials for trainers and an explication of the fundamentals of the New Careers model. (SG)
