Korean high schools are categorized into general, special purpose (gifted), vocational, and autonomous schools. Each high school has its own purpose for education, but until recently, Korean high schools have focused on achievements for university entrance. Studies have thus largely been limited to analyses of academic achievements. There is a lack of studies, however, that compare the parent support, teacher support, career maturity, self-directed learning, and school satisfaction between the different types of high schools. For this study, 1,141 students from high schools in Korea completed surveys (851 students: general school, 851 students: vocational school). Parent support, career maturity, and self-directed learning were the variables that made a significant difference between general and vocational high schools. Parent support and career maturity in a vocational high school was higher than that in a general high school. Self-directed learning in a general high school was higher than that in a vocational high school.
