Flowchart for Choosing a Category
Answer the following questions to find the category that fits you best.
Question 1: What is your current job?
Working on roads, bridges, tunnels, or river construction → Please choose Civil Engineering
Working on building or repairing structures → Please choose Building Construction
Working on electrical, water, air conditioning, or gas systems → Please choose Lifelines/Equipment
Question 2: What if I do multiple types of work?
If you work in multiple fields, choose the field where you have the most experience. It is easier to understand the exam content in a field you are already familiar with.
Question 3: What if my company specifies a category?
If your employer specifies a category, please choose that one. This is because the change in status of residence must match the duties at your workplace.

Common Pitfalls
Choosing based on pass rates alone
It is dangerous to choose Building Construction just because it has a high pass rate. Choosing a category that does not match your experience can actually make it harder to pass.
Mismatch between category and status of residence
When changing your status of residence after passing, your job duties at your employer must match the category you passed. Be sure to check with your company in advance.
Taking the exam with insufficient preparation
Once you decide which category to take, study intensively for at least 3 months before taking the exam.
Frequently Asked Questions

Yes, you can change your category when retaking the exam. However, since the scope of questions changes significantly, you will need to prepare thoroughly again.
