This study aims to identify the concept of mediate variables, plus the mediational model as one of the statistical models used in psychological and educational studies, and to identify statistical procedures to verify it, using various statistical programs such as the statistical package for social sciences (SPSS), and (R) package (mediation), by studying the effect of ambition as a mediating variable on the relationship of academic self-efficacy with achievement among students of Irbid University College. Two scales were applied on an available sample of 347 male and female students at the bachelor level: ambition scale, which consists of 28 items, and academic self-efficacy scale, which consists of 33 items, after confirming their validity and reliability. The results showed a partial effect of the ambition variable on the relationship between academic self-efficacy and achievement among students of Irbid University College. (Published abstract)
