Description¶
The guide presents an organizing framework of four evidence types that educators encounter when evaluating product effectiveness claims. The types are explicitly ranked: "The types of evidence in this guide are ordered from weakest to strongest, and each evidence description is accompanied by examples of information sources containing that type of evidence." The hierarchy serves as the guide's structure for helping educators judge how strongly each evidence type can back an effectiveness claim.
