Recent research on less-/more-skilled L2 listeners indicated that metacognitive intervention is more rewarding for less-skilled L2 listeners than more-skilled counterparts. However, since more-skilled L2 listeners achieved a repertoire of knowledge and skills, it is more difficult for them to achieve more improvement. Therefore, the scales of improvements are different between less- and more-skilled L2 listeners, and mere comparison between pre- and post-tests does not suffice. In this study, however, Fuzzy logic analysis was employed as a remedial approach in order to equalize these scales. Next, the comparison was made between less- and more-skilled L2 listeners to find out which group would logically benefit more from metacognitive intervention. A quantitative approach and quasi-experimental design were used to address the research questions. 65 Iranian students were selected including 31 more-skilled (15 advanced and 16 upper-intermediate) and 34 less-skilled (18 intermediate and 16 lower-intermediate). The instruction was based on metacognitive intervention in eight sessions. The result, which was based on a Fuzzy logic analysis approach, indicated that more-skilled L2 listeners benefited more than less-skilled L2 listeners from metacognitive intervention, and is quite contrary to the previous studies. This study is beneficial to the field of assessment. Assessment based solely on differences in pre-/post-test results may not be adequate in some cases. Researchers and teachers should consider other factors in their judgments. Metacognitive intervention is known as one of the effective approaches to increase listening skills and comprehension.
