Evaluations were initially employed to measure the effectiveness of programs because evaluators have a unique ability to influence innovative decision-making. Innovation requires not only the generation of credible evidence, but knowledge brokering for utilization by pertinent stakeholders. Federal evaluations can play an integral role in informing policymaking processes, but not all federal agencies have established evaluation policies, which can result in inconsistent and inefficient data practices. This has called for an Evidence Reform through the Foundations for Evidence-Based Policymaking Act (i.e. the Evidence Act) which is a means to professionalize evaluation in the US federal government. This paper will discuss the tremendous impact the Evidence Act will have on organizational evaluation capacity, culture, and practices.
