Some educational organizations still use traditional talent development methods that do not correspond to the preferences of millennial employees. Identifying the influence of mentoring on job performance among individual employees of the millennial generation may be especially useful as this generational cohort is the largest in the workforce. Using two validated questionnaires administered together, this quantitative, non-experimental study sought to determine if, and to what extent, mentoring and gender influence job performance among millennial employees in higher education institutes in the United States from the mentee's viewpoint. The study used the social cognitive career and generational theories as frameworks. Participants were employees who worked in higher education and who used social media. The study employed an effect size of 0.15 and a confidence level of 95%. The data indicated that mentoring is a statistically significant predictor of total job performance (p = 0.40), mentoring and gender statistically significantly predict task job performance scores (p = 0.49), mentoring and gender are not statistically significant predictors of contextual job performance scores among millennials (p = 0.285), and mentoring and generational cohort are not statistically significant predictors of total job performance scores among employees in higher education in the United States (p = 0.287). Future research could explore these relationships from the viewpoint of either the mentee's mentor or manager or consider other variables, such as race. This study contributes to positive social change by highlighting the value of mentoring to positively increase performance among individuals, educational organizations, and, ultimately, educational societies.
