Great question! The Seoul Metropolitan Office of Education uses EPIK to help recruit and screen English teachers for their positions. Once EPIK presents eligible candidates to the Seoul Metropolitan Office of Education, SMOE then hires those candidates and places them into schools that are available.
The Seoul Metropolitan Office of Education does from time to time fill positions itself, not using EPIK. These SMOE applicants that do not apply through EPIK are found by SMOE themselves through domestic postings for those already located in South Korea.
Teachers that apply to be placed in SMOE through EPIK may be referred to as EPIK Seoul applicants, however the two entities are seperate. Once the teacher is successfully placed in the SMOE program, they are officially an SMOE teacher and no longer an EPIK Seoul applicant.
