The research aimed to know to what extent Indonesian EAP students master high and mid-frequency words (4000-5000). Besides, it aimed to know the vocabulary size of Indonesian EAP students. To fill the gap, the research examined 128 Indonesian EAP students from two private universities in Indonesia. To gather its data, the research employed the Vocabulary Level Test of Webb, Sasao, and Ballance, and the Vocabulary Size Test of Nation and Beglar. The research findings have found that the participants have not yet mastered the high-frequency words and the mid-frequency words from 4000-5000 wordfamilies. The finding also reveals that the mean scores of the students’ vocabulary range between 6000 and 10000. It implies that the previous learning of the participants has not yet facilitated them to learn important vocabulary from 1000 to 5000 word-families. Thus, although they have a big vocabulary size, they might face problems when trying to understand some texts. The research findings are expected to increase English teachers’ awareness in general and EAP teachers’ awareness specifically of the importance of facilitating their students to learn high-frequency words.
