The purpose of this study is to discover what characteristics affect differences in the employment rate among specialized vocational high schools, while controlling the variables of individuals and families, noting that there is a significant difference in the employment rate among specialized vocational high schools. To this end, KEEP Data provided by KRIVET from 2004, 2005, 2007, and 2008 was used for this study. The key findings are as follows: First, the greater the active involvement on behalf of parents in the management of schooling, the lower the schools' employment rates. Second, if the students were satisfied with their major, this reduces the employment rate. Third, a healthy relationship among the members of the schools increases the employment rate. Fourth, implementing various programs for career education increases the employment rate. This result is significant because it demonstrates that the efforts of the specialized vocational schools can positively affect the employment rate. Also, this suggests that the issue of high school students' employment requires both social and government influences.
