Abstract
We undertook a paper-based questionnaire and a PAC analysis to investigate how Japanese native speakers assess learners of Japanese who participated in a visitor session. As it is said that Japanese native speakers tend to be tolerant of learners' Japanese, this research also shows that their assessments of learners' grammatical and phonetic accuracy are tolerant. However, it suggests that they pay attention to learners' reactions to assess how well learners understand what has been told to them etc. The PAC analysis of two native speakers clarifies their perspectives on the visitor session and the learners, and how they assess the learners' Japanese.
