Saxon Math has mixed effects on mathematics achievement for middle school students

Saxon Math is a core curriculum for students in grades K–12 that uses an incremental approach for instruction and assessment. New concepts are introduced gradually and build upon previously introduced content, giving students daily time to practice.

After reviewing 21 studies on the effectiveness of Saxon Math on the mathematics achievement of middle school students, the What Works Clearinghouse (WWC) found that five of the studies meet WWC evidence standards. These five studies included 6,601 students in grades 6–8 from 52 schools in four states. One study is a randomized controlled trial that meets standards without reservations and the remaining four studies are randomized controlled trials or quasi-experimental designs that meet standards with reservations.

Based on the evidence presented in these studies, the WWC found that Saxon Math has mixed effects on mathematics achievement for middle school students. To read the full report and learn more about these studies, go to http://ies.ed.gov/ncee/wwc/interventionreport.aspx?sid=448.
