The purposes of this research are (1) to examine the appropriateness of using Mochizuki's (1998) Vocabulary Size Test as an indicator of estimates of general English proficiency, and (2) to investigate which vocabulary size test (VST) is better for that indicator, the written VST or the listening VST. 401 senior high school students, who were divided into four groups, from two schools participated in this experiment. The subjects took either Mochizuki's written or listening VSTs and general English proficiency tests (Kawai-juku mogi-shiken or TOEIC IP). Middle to high correlation coefficients between VSTs and general English proficiency tests were found. The correlation coefficients between the written VST and general English proficiency tests are higher than those between the listening VST and general English proficiency tests. The item analyses were also conducted for VSTs using FACETS. High IRT reliability coefficients were confirmed for both VSTs, and no major differences in the means of standard errors and item discrimination powers could be found between the written VST and the listening VST. The results show (1) Mochizuki's VST is suitable as a quick and rough indicator of general English proficiency and that (2) the written VST may be more efficient than the listening VST.
