The aim of this study was to investigate school dieticians’ awareness of the necessity for nutritional education and job satisfaction via qualitative research. For this purpose, in-depth interviews were carried out with 10 school dieticians. Results revealed that all participants said that schools urgently need nutritional education, and dietary attitude and unbalanced eating habits were the most urgent matters to be addressed. They made various suggestions related to revitalization of nutritional education: turning dieticians into nutritional educators, improving awareness of teachers and parents, receiving training on appropriate teaching methods, and so on. In response to their tasks, they considered bargaining with vendors and examination foods as the most burdensome tasks. In response to questions about how participants were treated in their workplaces, all participants reported low job satisfaction due to excessive work, lack of promotion opportunities, and low salary. To improve this, participants recommended creating a task manual, strengthening their role as managers, increasing their salary, and so on. Therefore, institutional support is necessary for dieticians to efficiently handle their excessive workload. In addition, an educational environment where dieticians can effectively carry out nutritional education needs to be created.
