In order to do so, the study selected 312 child care-givers in Seoul, Bucheon and Incheon. The results were as below. First, job performance was in order of daily schedule planners & performers, counselors & advisors, planners for educational curriculum, administrative business & administrators and researchers, and responsibility recognition was in order of daily schedule planners & performers, counselors& advisors, planners for educational curriculum, researchers and administrators and researchers. Second, the higher academic background and career, the more job performance they did and its subsequent responsibility recognition increased. Third, the child care-givers of state-supported facilities performed more job duties than those of private facilities and the former had higher responsibility recognition for job duties than the latter. Fourth, the more the number of classes, the more job performance they did, and the responsibility recognition was high in three classes.

Sixth, the fewer the number of young children there were, the more job duties there were for the planner for educational curriculum, counselors & advisors, researchers, administrators & managers; and the more the number of children there were, the more daily work schedule and performers' duties they did, and responsibility recognition was high when the number of children were less.
