In recent days, Competency mapping has gained great esteem as a way of identifying the skills and capabilities needed to excel in the domain of Human Resource Management. In the present context, the feasibility of establishing the competence level of HR students (postgraduates) has been studied, and whether such competency is being developed or not, during their program of study in line with core HR competency dimensions such as recruitment & selection, training & development, performance management, compensation management and employee relations. The present descriptive research was conducted among 90 post graduate HR students studying in and around Tamil Nadu, in which data were collected by applying structured questionnaire, using purposive sampling approach. Percentage analysis and statistical testing were done on the collected data of the research. The study results indicated that 56.6% of the respondents were female, and a large number of students had secured moderate to high competency scores in recruitment & selection, training & development aspects. The study also indicated that above 54% of the students had prior exposure to HR related software which obviously contributed towards their composite competency levels in the field of HR. The statistical tests with respect to various exposure to practical aspects including internship, and HR related workshops, displayed positive impact on the development of competency levels in students. The study leaves scope for improving industry exposure of students, and inclination towards competency-based education to increase competence levels of post-graduate HR students.
