During the coronavirus pandemic, online education continued to expand across varied educational factors. Therefore, the teachers had to develop and change some of the strategies used in their classes previously. Online classroom management is a synchronous-based online learning environment in education that is worthwhile to modify. For this purpose, the current study sought to understand the perceptions of classroom management and teaching self-efficacy by Iranian EFL teachers during the Covid-19 pandemic. Concerning sampling, 100 male and female English teachers constituted the study sample. Data were collected via Online Teaching Self–Efficacy Inventory questionnaire through different online platforms. The findings reflected that EFL teachers could select appropriate classroom management during online and face-to-face classes. In addition, the teachers had a positive attitude toward managing the classroom during the Covid-19 pandemic. The implications of this study may open up new perspectives into successful pedagogy for, teachers and students in outbreak days.
