This study investigates the impact of human resource training and development on the duties and functions of employees at the Human Resource Development Office (HRDO) of Mindanao State University – Main Campus, Marawi City. Utilizing a descriptive research design, data were collected through surveys from 33 regular employees. The findings reveal that both formal and informal training programs—such as workshops on data privacy, performance management systems, and orientation seminars—are implemented within the unit, with a high level of employee participation. Employees perceive these trainings as very important to moderately important for effectively performing their specific duties and responsibilities. However, the study identifies serious challenges hindering optimal training effectiveness, including lack of employee engagement, ineffective training methods, and nepotism. The results underscore that while training is crucial for enhancing employee productivity and competency, addressing systemic problems is essential for maximizing its benefits. Recommendations include stricter attendance policies, improved training implementation, team-building activities, and merit-based selection processes to foster a more effective and equitable training culture.
