The purpose of this study is to explore a practical and theoretical method to develop and utilize a competency-based recruitment system. In the face of the stark reality that only education and certifications are considered important in Korea's labor market, we attempted to devise a measure to enhance the rationality of the labor market. More specifically, we developed and applied practical tools needed for competency-based recruitment system to enhance the efficiency of securing human resources, and to support participants in the labor market in their search for and selection of jobs. We selected three types of jobs, given the importance of the jobs and the number of people employed in each one. These jobs are in business management, production management in the manufacturing industry, and a clerical job in the financial industry. We conducted competency modeling for the three types of jobs by using existing approaches at home and abroad. To take advantage of these efforts, we developed recruitment tools including competency-based application form, competency tests, and competency-based interviews and investigated suitability of each. Finally, this study suggests theoretical and policy implications to enhance the utilization of competency-based selection.
