Jinjamhyanggyo Confucian School was established to enshrine and orient the ancestral tablet of excellent classical scholars in 1405 (the 5th year of King Taejong's reign) and to educate people. More detailed information is not available in the record. The remaining building is called Daeseongjeon, and the ancestral tablets are 5 Seong, Songju 6 hyeon, and Korean 18 hyeon.

Daeseongjeon (Cheongju Daeseong High School (Former Main Building of Cheongju Commercial High School) is designated as a Registered Cultural Heritage.
