ABSTRACT
Frameworks, concepts, and inferential methods are, at least for me, the most interesting parts of the assessment toolbox. However, they all depend on information from the literature, measurements, observations, or expert judgment. Information is data or other facts used to derive evidence. Your primary source of information for an assessment is likely to be the existing literature. The author explains how to use a structured and transparent literature review process that produces systematic reviews, which should ultimately result in a data set that is nearly complete, unbiased, and reproducible.
