The purpose of this paper is to highlight the benefits of the experiential learning in non-formal adult vocational training environments by applying the Project Method. The method of teaching itself derives from the Greek antiquity and is based on the experiential works of Dewey, Lewin, Piaget and Kilpatrick. As an experiential learning technique it consists of four different phases described below: speculation, planning the didactical activities, conducting the didactical activities and evaluation. During the implementation of the experiential learning it appears that adult trainees activate competencies of emotional intelligence and learning skills. Thus, the function of thought is that of an effective tool for problem solving and action. The assessment process was undertaken with the multimethodical approach to determine whether it can be applied to an entire group of adults, training in marketing communications as well as a variety of similar fields. This application proposes fertile speculation about alternative, practical instruction in the future institutes of broader vocational training as well as their effective connection with the economical and societal environment.
