This research study aims to determine the vocabulary input of foreign students in the basic level BIPA (Indonesian for Foreign Speakers) class. Many experts state that the frequent repetition of a word will make it easier for foreign students to memorize and rephrase it, both orally and in writing. This study uses a qualitative descriptive with a corpus study. AntConc software is very helpful in the process of collecting research data. There are three things that can be obtained from this research. First, the types of words in the BIPA Book 1 are 1,559 words with 9,456 tokens and 1,264 words in the BIPA 2 Book with 7,073 tokens. Second, the percentage of word types is divided into low frequency words with 70.88% in BIPA Book 1 and 69.78% in BIPA Book 2. Medium frequency words with 12.77% in BIPA Book 1 and 13.93% in BIPA 2 Book High frequency words with 16.36% in BIPA Book 1 and 16.30% in BIPA Book 2. Third, the types of words that enter into low frequency words have a high percentage. This makes it difficult for students to remember a word for a long time due to the lack of repetition of words.
