In this paper, three types of Japanese online tests, and self-assessment questionnaires comprised of 13 descriptor categories, including one category on Japanese orthoepic competence, were issued to ...15 Japanese language learners attending language schools in Japan. As a result, we confirmed a more than moderate positive correlation between the orthoepic competence descriptors and test scores, both concerning the individual scores on the three tests and the aggregate total of those scores. Based on these test results, learners were categorized into different skill levels, such as novice, intermediate, and advanced. Learners who scored at the intermediate level with their grammar test or scored over 170 total points across all tests tended to evaluate themselves at a B-level or higher competency level.
