As a part of a more extensive computerized dynamic assessment (CDA) project delivered through a dedicated website, www.lingeli.com, this study explores EFL learners' perspectives on an online listening comprehension dynamic assessment software focusing on inferential listening skills while trying to minimize the guessing effect. The study participants were 94 Iranian EFL learners selected through convenience sampling to participate in a 1-month dynamic assessment targeting EFL learners listening comprehension using the developed software. The researchers involved half of the study participants in semi-structured interviews held in their native language (Persian) to shed light on the pros and cons of the software. Six major themes emerged from the interviews' content analysis, encapsulating participant'' generally positive perceptions and some negative perspectives about the software. They perceived the CDA software as novel and interesting, stress-relieving, supportive, convenient, and cost-effective in terms of time and money, and removing the time and location limitations. In contrast, a few others assumed it was time-consuming and stressful, with limited learning and ignoring the benefits of social aspects of teaching. The study's findings recommend that learners' perspectives be considered when developing future CDA listening comprehension software to increase the validity of CDA projects by addressing their drawbacks and fully implementing the CDA test's potential to enhance EFL learners' listening comprehension abilities.
