The present study explores whether cloze test scores under two different scoring methods and English test scores on TOEIC can predict written productive vocabulary of Korean EFL learners. One hundred and fourteen students’ written productive vocabulary in summary writing was analyzed using VocabProfile, which provides four frequency-based vocabulary level lists: the most frequent 1,000 words (K1: function words and content words), second most frequent 1,000 words (K2), academic word lists (AWL), and off the list words (OLW). The study found that the exact-word method led to significant differences in K1, function words, K2, AWL, and OLW, and the acceptable-word method resulted in significant differences in K1, function words, K2, and OLW, indicating only one difference in AWL. On the other hand, the English proficiency test yielded significant differences in K1 and function words alone. These study results suggest that the cloze test under the two different scoring methods did not make a remarkable difference in the predictability of Korean EFL learners’ written productive vocabulary. In addition, both cloze test scores and general English test scores showed they could serve as predictors of Korean EFL learners’ written productive vocabulary, but cloze test scores led to more significant differences in vocabulary use in writing.
