Quality assurance of TVET in Korea has been mainly led by the government since 1960s and now this system is sustained by two quality assurance systems: National Technical Qualification System (NTQS), and Private Qualification System (PQS). Since 1973, NTQS has been administered by the MoEL, which is working as a quality controller of TVET in Korea. However, NTQS has unveiled a fundamental limitation in balancing between education and training, and qualification system, even though it has achieved remarkable outcomes in terms of total number of successful candidates. The root cause of the issue was the gap between National Technical Qualification (NTQ) and TVET, and industrial needs, which has caused ineffectiveness of the system.
