It is assumed that web-based dynamic assessment will continue to thrive and have a profound role in pedagogy. In this regard, explanatory sequential mixed-methods design was selected to consider the effect of web-based dynamic assessment on learners' autonomy. To this end, a sample of 60 male EFL learners at high school were chosen at non-random and categorized into two groups of web-based dynamic assessment and the control group based on the convenience sampling method. the learners’ autonomy questionnaire was used as a data gathering tool for pretest and posttest in autonomy. The high school students exposed to web-based DA via a designed web based on the level and requirements of the students in grammar, however, the learners in the control group learned the grammar by the traditional or conventional method of instruction. Based on the results of Mann-Whitney U test, the learners’ autonomy means scores in web-based DA increased in comparison to those of the control group. The platform and methods employed in this study produce results that are encouraging for the field of language instruction and could produce motivational outcomes in the future. The pedagogical implications of the study
