This guide is intended for anyone who wants to organize, lead and/or evaluate trainings (from one to several days) for a group of adults. It can be applied to trainings, important meetings, or workshops. The purpose of this guide is to provide practical support to people who organize and facilitate trainings. It stresses the idea that good training is always the result of careful preparation. This guide is based on the practical experiences of several trainers. Rather than a theoretical guide, the guide is a “collection of ideas” inspired of common experiences and includes key points to remember as well as many tips provided by experienced facilitators on how to respond effectively and in original ways to the needs of participants. This guide was developed for the West African multicultural context … but is usable for all regions of the world. It is only available in French.
