Yonhong, X., Hartman, S. Uribe, G., & Mencke, R. (2001). The Effects of Peer Tutoring on Undergraduate Students' Final Examination Scores in Mathematics. Journal of College Reading and Learning, 32(1), 22-31.

This article demonstrates that tutorial assistance, independent of variables of gender, Scholastic Aptitude Test (SAT) score, math placement level, and high school grade point average (GPA), had a significant effect on students' final examination scores in a mathematics course. It finds that math performance of the selected sample had a positive relationship to students' SAT score, high school GPA, and math placement level.
