The SLC is valid for 3 years and is easily renewable. To renew, just sign in to your account and go to the international sailing license are on the home signed in page. There you will see anything that is red and you must complete that item. 

As you can imagine, we have the responsibility of keeping everyone as competent and current in their knowledge as possible. This is why we set up such renewal parameters.

We are adding some software to allow you to reset the "most recent score". But for now you will need to keep track of the exam modules yourself to ensure you pass them all. It does not tell you now which ones you re passed now. i.e. make a list of each module and check off when you pass.
