The
What Works Clearinghouse (WWC) collects, screens, and identifies studies of
effectiveness of educational interventions (programs, products, practices, and
policies). The WWC regularly updates the WWC Technical Standards and their
application to take account of new considerations brought forth by experts and
users. Such changes may result in re-appraisals of studies and/or interventions
previously reviewed and rated. The current WWC Standards offer guidance for
those planning or carrying out studies, not only in the design considerations
but the analysis and reporting stages as well. The WWC Standards, however, may
not pertain to every situation, context, or purpose of a study and will
evolve.
