While the potential of Dynamic Assessment (DA) and its variants (Computerized Dynamic Assessment (CDA) and Group Dynamic Assessment (GDA)) for EFL classrooms has been recognized, there is a lack of research on its practical implementation compared to the well-established field of Summative Assessment (SA). Thus, the objective of this qualitative study was to investigate the evolving perspectives of EFL teachers concerning the integration of DA and SA within their classrooms. To achieve this, 50 EFL teachers in Iran were recruited through convenience sampling to complete an online open-ended questionnaire. The primary purpose was to explore their familiarity with, perceptions of practicality for, and preferences regarding DA and SA. Additionally, a sub-group of volunteer participants was requested to provide narratives detailing their real-world classroom experiences using DA and SA. Content and thematic analysis of the responses revealed that the majority of participants were familiar with DA, with the most commonly employed type being GDA. While DA was predominantly viewed as a form of feedback, SA was still seen as a more formal means of classroom assessment. Consequently, it is highly recommended that EFL teachers exploit the advantages of both assessment approaches in order to ensure more equitable decisions concerning students' abilities.
