Prepared for use by County Extension Home Economics Agents in training program aides, this document is a compilation of actual experiences reported by program aides working in a food and nutrition education program. These cases can be called "critical incidents" since they represent areas of success or failure in the minds of the aides. The cases are categorized under the following major task areas: (1) Enrolling new families; (2) Winning confidence and trust; (3) Creating and maintaining interest; (4) Organizing groups; (5) Conducting meetings; (6) Dealing with children and/or husbands; and (7) Involving other agencies and groups. There are suggestions for using the case studies. (Several pages of this document have been retyped.) (EB)
