Coast Guard COOL (Credentialing Opportunities On-Line) is a great source of information about the civilian credentials related to your Coast Guard job and other associated information. There is so much information, in fact, that it can seem overwhelming at first.If you are using COOL for the first time, we recommend taking a moment to look through the COOL Overview section. Specifically, the Site Features and Organization page lays out for you how COOL is organized and where you can find specific information.
Also worth noting are the chevrons along the top of each page:
These represent the steps of obtaining a credential. Click on each chevron for a details about how to complete each step. An important concept to understand is that COOL is not a credentialing organization—COOL provides information about credentials, and includes links to credentialing organizations. When you choose a credential, you will follow the links to the credentialing organization website and obtain the credential from them.
