Kumon Math. What Works Clearinghouse Intervention Report
What Works Clearinghouse
"Kumon Math," published by Kumon North America, Inc., is a supplemental mathematics curriculum for students in preschool through secondary school. The curriculum is not structured by age or grade level, but by a student's own pace, and is composed of hundreds of short assignments that progress through increasingly difficult mathematics skills. Students complete one assignment every weekday and attend a Kumon center for two sessions per week. Every assignment is timed and graded. Students master skills through repetition and cannot progress to a new skill before completing an assignment within a set amount of time and with close to 100% accuracy. New skills and exercises build on previously mastered concepts. The What Works Clearinghouse (WWC) identified five studies of Kumon Math that were published or released between 1985 and 2008. Two studies are within the scope of the review protocol and have an eligible design, but do not meet WWC evidence standards because there was only one unit of analysis in one or both conditions. Three studies are out of the scope of the review protocol. The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of "Kumon Math."
