The effect of mentoring on employee performance in universities is not thoroughly understood, even though it has been universally acknowledged as an effective tool for employee growth. This study examines the effect of workplace mentoring on employees' performance in private universities in Abuja, Nigeria. This is to evaluate the effect of Pedagogy and Psychological support on employee performance. The study adopted a survey research design, targeting a population of 2,118 employees from various private universities in Abuja. A sample size of 370 participants was determined using the Fisher formula. Data were collected through a questionnaire and analyzed using statistical regression techniques. These results indicate that psychological support has a statistically significant positive relationship with employees' performance, while Pedagogy does not demonstrate a significant relationship. The findings of this also highlight the importance of effective psychological support programmes and services in private universities in Abuja. It is recommended that these institutions prioritize developing and implementing such programmes to enhance employee performance. By providing adequate psychological support, employees can gain valuable guidance, support, and resources to navigate their career paths, leading to improved job satisfaction and overall performance.
