The purpose of this study was to find out the correlation between the level of academic background and the rules of Hangul orthography by examining the compliance of Korean spelling. To examine this, six universities were divided into three divisions by level into A, B, and C, and the status of marking by university was compared with the free bulletin board of Everytime, a college student community. As a result of the survey, A-grade K universities best observed the Hangul Hangul orthography followed by C-grade A universities. The university that did not keep the Hangul orthography well was a C-grade D university. By educational level, the grade with the lowest mislabeling rate is grade A. It can be seen that the status of compliance with the lexical norms is related to each level of education. However, it cannot be generalized because there are not many vocabulary in common from six universities, but there is some correlation between knowledge and actual notation.
