In the past several years utilization of nonprofessionals in various extension programs has increased. In an attempt to determine what the role of the Expanded Food and Nutrition Education Program (EFNEP) nonprofessional is, the paper presents the findings of an analysis of critical incidents acquired from nonprofessional EFNEP extension aides working in selected areas of Kentucky in the course of an evaluation study. The specific purposes of the critical incident analysis were to: (1) identify the on-the-job behaviors and attitudes of EFNEP aides through critical incidents described by aides, (2) determine critical job requirements by tabulating and classifying the identified behaviors and attitudes, and (3) draw implications from these data for the training of EFNEP Extension Aides. Findings led to the following recommendations: (1) training should be conducted on a one-to-one or very small group basis and (2) any training program for nonprofessionals should focus attention on not only involving the trainees, but all levels of staff responsible for the success of the program.
