This study investigates foreign language teachers' beliefs about information and communication technology (ICT) and factors contributing to their belief formation through in-depth interviews with eight teachers and the principal of a public primary school. The participants held overall slightly positive attitudes towards the effectiveness of ICT in English education but believed it played only a subsidiary role in their pedagogical practices and professional development. Elementary English teachers' ICT-related beliefs were shaped by individual-, institutional-, and policy-level factors. The study extends belief-related components of the technology acceptance model (TAM) by clarifying the external variables into three-level factors. The results suggest the need for in-service teacher education programmes and joint efforts from individual teachers, school management, and government authorities catering to teachers' ICT beliefs.
