research was conducted with the aim of investigating the lived experience of professors of formative evaluation during virtual education. This research was done using qualitative approach and phenomenological design. In order to collect data, semi-structured qualitative interview was used. The number of people participating in the research was 10 professors of Bu Ali Sina University, which was achieved by using targeted sampling, after conducting 10 interviews, and audio and visual recording and their content were implemented in textual form. Interview data were analyzed in three stages of open, central and selective coding to classify concepts and categories. In-depth analysis of professors' views led to the identification of factors in three areas. The findings of the research showed that the quality of students' learning was based on the implementation of formative evaluation in the form of meaningful and qualitative learning. Also, two major challenges include weakness in evaluation culture and human resources and weakness in infrastructure and facilities, and strengthening the pedagogical knowledge of professors is the most important strategy to improve the quality of formative evaluation. As a result, paying attention to these factors can lead to the high-quality implementation of formative evaluation in the course of virtual education.
