This study aimed at investigating the mathematics study skills that discriminating between high- and low- achievers in mathematics. The scale of Mathematics Study Skills was developed and used in this study, compromised of (25) items. Validity and reliability of this scale were established. The subjects of this study were (811) eighth, ninth, and tenth- grade students, selected from basic government school in Nablus, in the scholastic year 2012-2013. The study revealed the mathematics study skills that basic school students use, and determined those skills that discriminating between high- and low- achievers in mathematics. The results, also, showed statistically significant differences between the mean scores of students attributed to the variable of their grade, but showed no statistically significant differences attributed to the variable of their sex, or the interaction between their grade and sex.  A number of recommendations were made in the light of these findings.
