Despite this large and consistent body of work, a report published by the What Works Clearinghouse in November 2013 stated that it could find “no studies of Reading Mastery that fall within the scope of the Beginning Reading review protocol [and] meet What Works Clearinghouse (WWC) evidence standards” (WWC, 2013b, p. 1). This NIFDI technical report documents a surprising number of errors in the WWC analysis.enCreative Commons BY-NC-ND 4.0-USReading Mastery (RM)Direct Instruction (DI)Technical ReportTechnical Report
