Due to the importance of English in global society, English education at the college level in Korea has continually developed. The beauty faculty has also considered that English education is essential for success in their field. However, different approaches to the study English are needed for cosmetology students at college as they relatively little time to study English and, for the most part, it is not the main interest of their studies. Therefore, recently an ESP (English for Specific Purpose) approach, which focuses on the learner`s need, purposes and interest, has been put into practice at colleges. The purpose of this study is to investigate the ESP class implemented at colleges and discover the main motivations for studying in this way. For this study, eighty-eight cosmetology students participated and were surveyed in June 2012. Participants were asked to answer questions regarding their English learning motivation. This study overviews the definition of the ESP approach and analyses the effects of English learning motivation on ESP study. It also distinguishes the use of different English learning motivations by English ability. The results indicate that instrumental motivation had the greatest influence on ESP study, followed by extrinsic motivation, intrinsic motivation, and integrative motivation. This means that most cosmetology student study English to get paid better and to get a good job. The study has also found that highly- motivated students are prone to have better English abilities.
