This paper presentation analyses evaluation approaches and methods that are typically used to assess the impact of development training at several levels: impact on individuals’ evaluation knowledge, professional practice, and institutional change. The authors discuss different types of evaluation approaches that use direct measures. The authors point out strengths and limitations of each approach and suggest ways to mediate these limitations. Examples are drawn from evaluations of the International Program for Development Evaluation Training (IPDET.org), a development training institute (DTI) organized by the World Bank and the University of Carleton in Ottawa. In this context, this paper sheds light on an approach that would best inform upper-level efficacy questions some time after trainees have returned to their workplace environment, set within developing countries and organizations around the globe. #TeachingofEvaluation #EvaluationManagersandSupervisors #Evaluation2009 #capacity #2009Conference #EvaluationUse #Research,Technology,andDevelopmentEval #evaluation #Cluster,Multi-SiteandMulti-LevelEval #building #OrganizationalLearningandEvalCapacityBuilding
