This study aims to describe Indonesian EFL teachers' perceived perspective and self-efficacy in EFL teaching using ICALL, reveal the prominent factor influencing each variable, and examine the effect of the perceived perspective on their self-efficacy. This study used a cross-sectional survey design with a quantitative approach. There were 284 Indonesian EFL teachers taught in secondary schools chosen using a voluntary sampling technique as the respondents. Data were obtained by employing a Perceptify-ICALL questionnaire with forty items using a six-point Likert's scaling method ([alpha] = 0.839). Data were analyzed using descriptive statistics, hierarchical multiple regression, and MANOVA. Results showed that teachers' perceived perspective was in a very high category, but not for their self-efficacy. The prominent factor influencing their perspective was the support and facilities provided by the school and government in succeeding EFL teaching using ICALL. Whereas the most influencing factor of their self-efficacy was their skills in operating computers and AI. Another finding was the fact that the teachers' perceived perspective significantly affected teachers' mastery experience. This study suggests that Indonesian EFL teachers' perceived perspective in EFL teaching using ICALL is well constructed, but their efficacy is on the contrary due to lower skills in operating computers and AI-powered devices or programs. Future professional development programs in improving the teachers' computer and AI-operation skills are suggested to be undertaken as well as bringing the ICALL-based approach to EFL learning.
