The study pursued to determine the perception of the business students on the effectiveness of the On-the-Job Training Program of the Kalinga State University in four areas, namely support of the college, pre-placement activities, support of the host agency, and effectiveness of the on-the-job training in terms of academic, personal and enterprise skills. The study used descriptive methods using a survey questionnaire as the primary tool for gathering the responses of two hundred thirty-nine respondents. The study revealed that the students perceived the OJT program of the University as average. Also, the common problems encountered by trainees were a mismatch of tasks with the course program, lack of supervision by the adviser and supervisor, limited time for OJT, and lack of proper orientation about the work. Thus, the University needs to strengthen its support to student trainees; improve pre-placement activities, and enhance host agencies' support to develop trainees' academic, personal, and entrepreneurial skills. The University needs to establish guidelines in choosing host agencies to ensure the relevance and quality of training provided to trainees are aligned to their chosen fields. The findings of this study can be used to improve OJT programs for undergraduate students to ensure students' competitiveness.
