Objectives This study developed a subject certification system for the purpose of improving and managing the quality of teaching activities and subjects in university classes.
 Methods For this purpose, literature and case studies were conducted in the analysis (A) and design (D) stages according to the ADDIE model procedure. By combining this, the components, evaluation criteria, and procedures of the subject certification system were prepared, and a draft of the subject certification system was derived. In the development (D) stage, the final subject certification system reflecting expert review and improvement was confirmed. A pilot application was conducted in the implementation (I) phase. And in the evaluation (E) stage, satisfaction ratings were conducted on participating students and faculty.
 Results An expert review of the draft subject certification system was conducted and a final draft reflecting improvements was developed. In the final draft, the types of subject certification systems (competency-based, PBL-type), components (3 areas), evaluation contents (evaluation areas, criteria, items), judgment criteria, and operation procedures (step 9) were confirmed. The completed subject certification system was pilot-applied for two semesters and satisfaction ratings were conducted on participating faculty and students. Student satisfaction was higher for students in certified subjects (M=4.62) than for students in non-certified subjects (M=4.38). faculty satisfaction was higher for PBL-type subjects (M=4.57) than competency-based subjects (M=4.39).
 Conclusions This study is significant in that it developed its own subject certification system that takes into account the university's curriculum and operation conditions. It is expected that it will be useful basic research data for universities that want to introduce a subject certification system to manage the quality of university education and standardize classes in the future.
