The purpose of this study was to examine Korean vocational high school students’ perceptions of English classes and textbooks and propose plans to cultivate an educational environment to promote the sustainability of English education in vocational high schools. To this end, this study conducted a survey with 245 students at a vocational high school in Chonnam province. The findings reveal that the students perceived the difficulty level of English lessons rather distinctly and displayed differing needs for studying English. This suggests that English classes should target different proficiency levels and future career options, such as going to college or getting a job. Most of the students thought that English lessons and textbooks in the vocational school were irrelevant to the work they would pursue after graduation. As they were also aware of the importance of English for employment or advancement to higher educational institutions, they requested more specialized curriculum and materials for vocational English. Suggestions are made based on the findings.
