The lead trainers for the MENA Regional Campaign Schools, Shannon O’Connell and Abdul Salam Medeni, have come together to co-author this manual – a step-by-step guide to designing, preparing, conducting and evaluating a successful training program. A Trainer’s Guide: How to Design and Deliver Training with Impact focuses solely on the basic principles that a trainer should follow in order to gain the best possible outcomes from a training he or she delivers. In addition to providing instruction and guidance, O’Connell and Medeni share their stories and lessons learned based on their experiences. These examples will aid readers in conceptualizing how and why these core training tactics are effective.
