This thesis is to identify the way civil examinations influence Gyo-Hwa(敎化) at schools, especially at Sung-Kyun-Kwan(成均館), in the early Yi-Dynasty. For this, it was examined what influences Won-Jum(圓點) regulation, Gang-Gyung(講經) regulation and Byul-Si(別試) could have on the students of Sung-Kyun-Kwan. And the conclusions are as follows:
Firstly, most of students did not abide by Won-Jum regulation, a kind of the obligatory boarding regulation, not only because the conditions of boarding at Sung-Kyun-Kwan were very hard but because there were many other expedients.
Secondly, they also took exception against Gang-Gyung regulation, a sort of oral test about Confucian classics, but they postponed expedientially it or studied the only parts expected to be made for the test.
Thirdly, Byul-Si, extra civil examination, made them take expedients for getting Won-Jums and pursuit the short term policy for succeeding in Byul-Si.
Fourthly, after all, Gyo-Hwa policy using civil examinations for Sung-Kyun-Kwan students failed owing to students\' utilitarian thinking as well as administrators\' poor insincerity.
Lastly, any administrators who wish to succeed in applying new educational policies should consider what students\' utilitarian concerns are.
