The purpose of the study was to examine job satisfaction, work performance, work satisfaction, perceived needs and self-evaluation of knowledge and skills of nutrition teachers. Survey questionnaire was administered to 106 nutrition teachers in schools of Gyeonggi area. Subjects were categorized into high- or low-job satisfaction group, and study variables were examined by job satisfaction group. Overall job satisfaction was high, with a mean score of 14.9 out of 20. High-job satisfaction group had more favorable perception regarding human relations and workplace atmosphere compared to the counterparts (p < 0.001). Work performance, examined by 12 items, was not significantly different between the two groups. However, satisfaction regarding specific work of nutrition teachers was significantly different by job satisfaction (p < 0.001). High-job satisfaction group responded that they had more knowledge and skills in areas such as food purchase management, food sanitation and safety management, equipment and facility management, nutrition education, nutrition counseling (p < 0.01), and general management & marketing (p < 0.05). High-job satisfaction group also indicated that nutrition teachers need to have more knowledge and skills than the counterparts, regarding food purchase management (p < 0.001), nutrition education (p < 0.01), nutrition counseling, general management and marketing, and teaching practices (p < 0.05). In addition, study results showed significant positive correlations among study variables. This study suggested that job satisfaction of nutrition teachers might be increased by having favorable human relations and workplace atmosphere, increasing satisfaction with specific work of nutrition teachers, and by increasing the knowledge and skills required for the work of nutrition teachers.
