According to the report of The Steering Committee for the Test Of Proficiency-Huayu (SC-TOP), most of CSL (Chinese as a Second Language) learners in Taiwan taking The Test of Chinese as a Foreign Language (TOCFL) use Practical Audio-Visual Chinese series as the primary learning material. Thus, the content and vocabulary in the series have a clear impact on CSL learners’ learning and on their test performance. However, very few studies focused on comparing the vocabulary used in Practical Audio-Visual Chinese (PAVC wordlist) with “Chinese 8,000 Vocabulary” (TOCFL wordlist). In this study, we compared the vocabulary in the PAVC series of textbooks and TOCFL wordlist and found: (1) 3,693 words are shared by both PAVC and TOCFL wordlists, while 2,085 words in PAVC are not covered in TOCFL list. And TOCFL has 3,776 words that are not found in PAVC. (2) The criteria for selecting words in PAVC wordlist are different from those in TOCFL wordlist. (3) The PAVC contains more vocabulary items related to Taiwan features than TOCFL wordlist does. (4) The TOCFL wordlist contains a larger number of -er words than the PAVC does. Based on the results of comparison, we suggested that 314 high-frequency words in the PAVC could be included in TOCFL wordlist, and 289 words from the TOCFL wordlist could be incorporated into the PAVC. The findings of this study can serve as a useful reference for Chinese learners, teachers, textbook compilers, and language test agencies.
