Research data collected by training observation, interviews and document analysis in the case study research of the civil service professional development training practice in Athens, GA demonstrate the preference of the practice-oriented, interactive small group training, which seem to maintain their popularity despite the growing online training market. If the local government registers for a webinar, they combine it with a group session usually facilitated by the head of the department. Interviewee K. D. pointed out that the starting point for the trainer should be the fact that adults learn best when they are part of the training, when they are able to contribute, they bring their own experiences to the learning. It is the asset and the added value the trainer has to rely on.
