The aims of this study were to identify pre-service early childhood teachers' perception, interest,
attitude, and knowledge of teaching English in early childhood, and impacts of these factors on their
teaching efficacy. The subjects of this study were 56 freshmen majoring in early childhood education
of a college in S city, Gyeonggi-do. They were required to answer questionnaires about their
perception of teaching English in early childhood and their teaching efficacy. The collected data was
analyzed using SPSS 20.0. The results of the study are as follows. First, majority of pre-service
teachers think that teaching English in early childhood is needed. Second. pre-service teachers are
willing to taking part in teaching English to young children, but they think that their participation
would be limited due to both their insufficient English and lack of teaching methods. Lastly,
pre-service teachers' interest․attitude and knowledge of teaching English have significant impacts on
their teaching efficacy. Implications of these findings for supporting pre-service teachers to improve
not only their teacher professionalism but also the quality of early childhood education and English
