In 2000–2001, the ARC Center, located at the Consortium for Mathematics and Its Applications (COMAP) [], carried out a study of reform mathematics programs in elementary schools in Illinois, Massachusetts, and Washington. The study examined the performance of students using three elementary mathematics curricula—Everyday Mathematics; Math Trailblazers; and Investigations in Number, Data, and Space—on state-mandated standardized tests administered in spring 2000. The study included over 100,000 students, 51,340 students who had studied one of the three reform curricula for at least two years and 49,535 students from non-using comparison schools matched by reading level, socioeconomic status, and other variables. Small differences on the SES variables remaining between the reform schools and the matched comparison schools were further controlled by adjustments based on regression analyses. Usage of the reform curricula was verified by a telephone survey of schools and districts.
