Hello vkcjsdlekt! Congratulations on passing!!! :) Maintenance is something that must be done, and I believe that if you do not meet certain standards, you may be disqualified. From what I remember, it started this year, and I believe that there is a separate page for maintaining qualifications so that you can manage your qualifications. The cost of maintenance training is quite expensive... but if you need to maintain your qualifications, participating in maintenance training is the easiest(?) way to do so. There are other methods, but since the recognition requirements and scope are relatively narrow, it is actually difficult to do without maintenance training ;)

vkcjsdlekt. That's right. When I was working, I tried to fill my resume with my work experience, as well as related education and seminars, but it was practically impossible, so I had to take continuing education. At that time, there were only offline courses, so I remember going all the way to Seoul to take them 😢_😢
