AB - I have served OPI as a tester for the past 7 years and always had the following two questions every time when I conducted it: that is, (1) Is there a strong relationship between the level of the JLPT vocabulary used by examinees and the level of OPI?; and (2) Can the gap of examinees’ vocabulary levels be a main factor for the separation between Advanced Level and Intermediate Level in OPI? This paper observed utterances of 10 OPI examinees, and investigated the level of vocabulary in terms of JLPT (i.e. N1, N2/N3, N4, and N5 level) as well as frequencies of vocabulary for each level. As a result, (1) OPI Advanced learners appeared to use N1-level words more than 2% overall. Therefore their data had around 1700-1800 words overall. There was a gap between N2/N3-level vocabulary and N4-level vocabulary. Further, for both OPI Advanced and Intermediate levels, N5-level vocabulary occupied around 70% overall. Statistics analysis (Estimation of population variance) showed its general feature of occupancy in N5-level vocabulary. Lastly, the underlying principal was confirmed as such that OPI ratings relied on the appropriate usage of words, and not on the presence of words themselves.
