Origins
The grade emerged from a 1990s overhaul of the National Technical Qualification system, which merged the old Craftsman Class 1 and Engineer Class 2. As junior-college graduates multiplied, Korea needed a credential matched to their training. The new grade certified "field technologists" who combine practical skill with theory.
Eligibility and exams
Candidates qualify with a related two- or three-year degree, a Craftsman license plus one year of related work, two years of related work, or approved vocational training. The written test usually covers four or five subjects. Candidates need at least 40 in each and an average of 60. The practical test requires 60 points. High-demand fields include electrical work, hazardous materials, and industrial safety.
Compared with Engineer
The Engineer grade targets design, analysis, and engineering management. Industrial Engineer focuses on technical work in the field. Many electrical, fire, and hazardous-materials regulations accept it for mandatory safety-manager posts, which gives it real hiring value. One year of work after earning it unlocks the Engineer exam, which makes it a stepping stone for people without a four-year degree.
