This research investigates the impact of shadowing mentors on the work readiness of fresh graduates employed in private companies. Recognizing the challenges graduates face in adapting to professional environments such as limited practical experience, underdeveloped soft skills, and unfamiliarity with workplace norms this study explores how structured mentor shadowing can bridge the gap between academic learning and job performance. Utilizing a quantitative approach with a descriptive-correlational design, data were collected through questionnaires distributed to 120 recent graduates who participated in mentor shadowing programs during their initial employment period. The findings reveal a strong positive correlation between the extent of shadowing experiences and levels of work readiness, particularly in areas such as adaptability, professionalism, communication, and task efficiency. Regression analysis further confirms that shadowing significantly contributes to improved workplace integration and productivity. These results align with both Experiential Learning Theory and Social Learning Theory, emphasizing the role of observation and real-world exposure in developing professional competencies. The study concludes that mentor shadowing is a valuable tool for enhancing graduate employability and easing the transition into the workforce. It highlights important implications for private companies, educational institutions, and policymakers in designing strategies that support graduate development and improve organizational outcomes through structured mentorship programs.
