These are the PowerPoint slides from the Communities of Practice: Building the Capacity of New Evaluators presentation at Eval19.Abstract: Much of the current evaluation training and learning literature focuses on formalized education such as coursework, required practicums, and internships. At the same time, research has suggested there is a gap between the outcomes of these formal education experiences and development of evaluation competencies. This leads us to ask, “What other paths exist for emerging evaluators to gain confidence and competency in evaluation practice?” We propose a community of practice as a way to foster knowledge sharing and competency growth while also supporting the development of an evaluator identity. We will discuss how a community of practice for transdisciplinary graduate research assistants can serve as a model for innovative evaluation training. We will offer insights for implementing this model in the context of differing organizational structures and evaluation philosophies.
