Evidence-based reviews are a type of systematic literature review used to identify evidence-based practices. When conducting an evidence-based review, researchers apply predetermined standards to identify evidence-based practices--practices that have been shown to reliably improve an outcome for a population of learners, according to evidence from a body of rigorous, experimental studies. In this article, we describe evidence-based reviews, provide an overview of one set of evidence standards used in special education, and describe important caveats and considerations related to evidence-based reviews. We conclude with two examples of evidence-based reviews in the field of learning disabilities. Our take-home message is that evidence-based reviews are a trustworthy approach for identifying generally effective instructional practices--but no practices, not even evidence-based practices, are effective for all learners.
