This article reports on an exploratory study of English as a foreign language (EFL) teachers' attitudes, beliefs, and professional knowledge about teaching EFL (TEFL) in a preschool setting in China. The investigation is structured on a two-dimensional grid based on Calderhead's (1996) categorisation of teachers' attitudes and beliefs and Richards's (1996) two-dimensional division of EFL teachers' professional knowledge. It aims to explore relationships between teachers' attitudes and beliefs and their professional knowledge as well as their connections to views on a TEFL professional development program. The study shows that EFL teachers demonstrate an eminent form-focused inclination in their beliefs and professional knowledge, which is translated into a strong desire for new teaching methods to be introduced in a professional development program. The article concludes with a brief account of the study's implications for the design of a TEFL professional development program.
