Updated standards are now available by clicking on the link below. All intervention reports, quick reviews, and practice guides released after January 1, 2009 include a footnote to help the user better understand which standards were applied to the research reviewed. For those intervention reports, quick reviews, and practice guides that do not have a footnote, Version 1.0 Standards were applied. If you have any questions about WWC evidence standards or the roll-out of Version 2.0 Standards, please contact us.
