There are hundreds of FEMA endorsed classes as part of the National Incident Command System, or ICS. Most begin with ICS 100, 200, 700 and 800 which are the basic courses explaining the system and its methodology for operations. You do not receive a card, however you do receive a mountable certificate, and a smaller version (like 5x7) which can be folded and put in your wallet. These courses are generally availabe through your local Emergency Management agency or your municipalities emergency operations center. But they can also be taken online for free.
You will not get a "FEMA ID card" for taking FEMA courses. You will get a certificate. There is a Certified Emergency Manager program that is offered at the State level, if you state has one. Each individual if they have the program requires you to take a certian amount of FEMA online independent study classes as well as their own state classes. I have taken almost all of the fema independent study classes as well as I am a state certified emergency manager. And FEMA or my state gives you a ID card. The classes offered online by fema are free and are good classes. I would recommend to anyone who would like to learn more about Emergency Preparedness, or First Responders.
