This study aimed at drawing a scheme for more developmental and rational improvement of the screening examination system to cope with the rapidly changing industrial environment positively, enhance the food service industry qualitatively, and reinforce engaged specialty of those engaged in the industry. To set a rational improvement scheme for a cook screening system, the study conducted a prior study on job analysis of those engaged in cooking, a review on relevant laws, and a theoretical research on those problems in the current cook screening examination system. On this basis, it understood the actual condition of the current cook screening system and implemented a demonstrative analysis through a survey to draw a section on a future improvement scheme. The results were analyzed largely from two viewpoints: the general condition of the cook screening system and the future improvement scheme for the system.
