Career Development and Qualifications

Qualification Certificates Are Not 'Stock Certificates' But 'Access Permits'

On-site qualification certificates are not proof that you "do well." They prove you have the right to be assigned to a position. By law, only qualified individuals can perform certain tasks, and many prime contractors require subcontractors to have a certain number of qualified personnel.

Most manufacturing in the Busan–Ulsan–Gyeongnam region follows a prime contractor–first-tier–second-tier subcontractor structure, so this is not just an individual issue. When renewing internal subcontracting contracts, the condition of "how many qualified personnel are present" can determine whether a line survives or not. For new hires, this is often the fastest way to make an impact.

> National technical qualifications have no nationality restrictions. Colleagues working on an E-9 visa can also take the exam. While there is a barrier of a Korean language exam, it does not block the qualification itself.

1. There Are 5 Levels, But It's Not a Straight Line

According to the National Technical Qualification Act, the levels are as follows:

Although people often say "Functionary → Industrial Technician → Technician → Engineer," Master Functionary is a branch off this line. If you want to reach the highest level while continuing hands-on work, become a Master Functionary; if you want to move toward blueprints and documents, go for Technician or Engineer. In the field, Master Functionaries are not treated any worse than Technicians.

2. Eligibility — You Cannot Skip Levels

This is the key point. You cannot take the Technician exam just anyone. You need experience or a lower-level qualification to be eligible.

Only experience in "identical or similar job fields" is recognized. You cannot take the Industrial Technician exam in the machinery field with 3 years of experience in a warehouse. Experience verification is done through employment certificates and 4 major insurance enrollment records.

The Master Functionary course is not about education requirements but a door that opens only if you have prior qualifications. Only those who first obtain Industrial Technician or Functionary qualifications can take the Master Functionary course and gain eligibility.

> Eligibility criteria vary by subject and are subject to revision. Before applying, check the eligibility requirements for the subject directly on Q-Net (Q-Net). If you apply without meeting the qualifications, your pass may be revoked later.

3. Getting a Functionary Certificate First Saves Time

[High school graduate employee · Changwon machining subcontractor · Hired in March 2026]

2026.03 Hired, started work 2026.10 Passed Computer-Aided Lathe Functionary exam ← No exam restrictions, possible in the first year 2027.10 1 year after obtaining Functionary certificate → Eligibility for Industrial Technician exam secured 2028.03 Passed Computer-Aided Machining Industrial Technician exam 2029.03 1 year after obtaining Industrial Technician certificate → Eligibility for Technician exam secured

If the same person tries to take the Technician exam without any qualifications 2026.03 + 4 years = 2030.03 eligibility starts

→ Just obtaining one Functionary certificate in the first year moves the Technician exam date forward by 1 year

The first year after hiring is the most important. At this time, there are no exam restrictions, so you can take the Functionary exam even without doing anything. After about 3 years, when you think "maybe I should get a certificate now," the waiting period starts again from that point.

4. Qualifications That Actually Have Value in Manufacturing

Quality management and industrial safety do not have a Functionary level. Since you must start at the Industrial Technician level, if you want to go this route, you must create eligibility through experience or education. Plant maintenance is similar, with only a Technician level.

In addition, there are qualifications that are immediately useful on-site.

• Forklift Driver Functionary — Used everywhere in logistics and shipping. Forklift driving requires a construction machinery operation license, but for forklifts over 3 tons, this qualification is effectively the only way (for under 3 tons, a license can be issued after completing training at a designated institution)
• Hazardous Material Functionary — If the storage amount of solvents, cutting oil, or paint exceeds the designated quantity, it becomes a mandatory appointment target
• HVAC and Refrigeration Machine Functionary, Energy Management Functionary — Responsible for utility equipment

5. Qualifications Become Legal Appointment Requirements

The reason why Technicians and Industrial Technicians are particularly valuable is because the law requires them.

> Appointment criteria vary by industry, company size, and equipment capacity and are frequently revised. To check what appointment obligations your company has, directly check the relevant law on the National Legal Information Center.

6. How Are the Exams Conducted?

• Many subjects use CBT (Computer-Based Testing), and you can see your pass status right after the exam ends.
• Written exam results are valid for 2 years from the date of announcement. Even if you fail the practical exam, you don't have to retake the written exam within 2 years. Many people waste this 2-year period.
• Regular exams are usually held 3–4 times a year, with different schedules per subject. Based on the implementation plan released at the beginning of the year, plan your schedule for the year in advance.

7. Common Mistakes New Hires Make

Checklist for Choosing Your First Qualification Certificate

• Chose a subject directly related to your process (e.g., lathe operator → Computer-Aided Lathe Functionary)
• Checked eligibility and this year's implementation schedule on Q-Net
• Wrote down the written exam registration date and practical exam registration date on a calendar
• If the practical exam is practical-based, asked the team leader if you can practice using the company's equipment
• Checked if the company has a support system for exam fees and training costs
• Checked the wage bonus or promotion reflection for obtaining the qualification in the personnel regulations
