Standards of Evidence

An increasing focus and emphasis on evidence-based information and practices is occurring in almost all sectors today. Service providers, policymakers, and people with disabilities and their families are asking more and more the question "what works".  What do we actually know across a range of related research studies? Standards of evidence are usually applied to assess the quality and rigor of individual research studies to determine the findings that should be included (or excluded) from an evidence pool of related findings.  Through systematic review processes, it is possible to show, across a series of high quality research studies, what the results in the evidence pool indicate about "what works."
