The purpose of this study was to investigate the basic materials for enhancing the professionalism of 51 infant/toddler teachers through in-depth interview about the actual condition of child care centers. The results were as follows: First, the infant/toddler teachers got less credits of young child care and education subjects than day care teachers did. The current criteria for qualification of infant/toddler teachers was not appropriate for providing the child care services. An efficient and substantial curriculum must be designed to facilitate the day care services for infant/toddler teachers. Second, the infant/toddler teachers recognized that their roles were similar to child care teachers. The curriculum and practice must encourage and nurture the characters, beliefs, and dispositions of infant/toddler teachers. Third, it is necessary to review the various problems to enhance the professionalism of infant/toddler teachers. Several suggestions for enhancing the professionalism are discussed.
