With the new government in operation, the government is actively pursuing the government's policy of making non-regular workers permanently employed in the public sector. The policies implemented to stabilize the status of workers are expected to cause a huge change in the working environment across society. Also, after full-time work, discussion of the personnel system will inevitably follow. Agencies that only work in a specific field in the public sector may need one consistent system in personnel management, but may have a variety of professions, and have a high rate of non-regular employment, and have experienced cultural difficulties with the arts. In particular, the Korean general art school under the Ministry of Culture, Sports and Tourism, which has both public sector and culture and art institutions, can be seen as a subject of much discussion when designing personnel systems. It appears that the introduction of a job-level system is seen as an alternative to the current personnel management system. The job class is a concept that contrasts with the previous mean-centered personnel system, in which each position's job values were evaluated and compensated through job analysis. We will review the concepts, classifications, and design methods of this work, and more detailed information on how they can be designed when they are actually applied to the Korean National University of Arts. I hope that what is proposed in this study could result in a meaningful statement for the public, cultural and artistic institutions, and for educational institutions.
