The purpose of this study was to examine eighth grade students' algebra achievement scores across various states, over years, and by students' demographics (including ethnicity/race, language spoken at home, SES factors, and academic resources). The questions guiding the study were, (a) What are the differences in eighth grade students' algebra achievement scores across sixteen states between the years 2005 to 2015? (b) Are there significant differences in eighth grade students' algebra achievement scores by student demographics? There were significant differences found in the students' algebra achievement scores based on different students' demographics. Further, the students' mean algebra scale scores continue to rise over the years. [For the complete proceedings, see ED583608.]
