Providing training to staff has many costs: the cost of resources involved in preparing and giving the training, the cost to participating organization in travel and lodging, and the cost of staff being away from the workplace. To justify these costs, managers need to feel confident that the training they are providing, or asking their staff to attend, will make a difference in staff performance. They need to know that staff members have not only acquired new knowledge, attitudes, and skills from the training but can, and do, put them into practice back on the job. The proposed course “impact evaluation of training programmes” is designed as a research-based approach to the evaluation of training programs and other interventions which in turn allows for practical assessments of organizational impact and business gains. Participants will acquire the skills for uncovering systemic factors that contribute to a positive impact, as well as the reasons for neutral or negative outcomes from a training intervention.
