The university curriculum has been urged to incorporate 21st-century digital competence and skills, particularly information literacy, in accordance with recommendations made by numerous organizations, including the Scientific and Cultural Organization (UNESCO) and the International Society for Technology in Education (ISTE). Instructors are then considered true facilitators in this sense. Therefore, recent studies investigated the factors that shape teachers' competence in developing learners' information literacy by exploring contextual factors such as the availability of information and communication technologies (ICTs) and internal factors such as their attitudes. This study aims to shift the focus from exploring contextual factors or teachers' attitudes to exploring instructors' individual ICT-related factors. Through a bi-phenomenon analysis, this study leveraged teachers' professional knowledge and ICT-related teaching skills in shaping their competence to develop learners' information literacy. To do so, 346 university English as a Foreign Language (EFL) lecturers in Iran voluntarily participated and answered the study instruments. The result of the partial least square modeling approach (PLS-SEM) revealed that lectures' skills in designing the procedure to develop university language learners' information literacy and integrating psychological factors, such as self-regulation and attitude, as well as the skills to implement the procedure and handle unforeseen challenges effectively cultivate information literacy. The professional knowledge areas of planning, exertion, and ethics were also recognized as preconditioning factors in this manner. In addition to introducing a new conceptual framework to the literature, the findings of this study also make recommendations on how lecturers can upgrade their action-oriented skills and professional knowledge to increase learners' information literacy. Executive managers should also update their recruitment criteria and evaluate lecturers' skills and knowledge during recruitment.
