I'm EMT-B certified and my certification was about to expire over the summer so I did a 24 hour EMT refresher course, sent in my payments and got a new certification for two more years (I haven't been practicing at all, but will start this summer). Anyway, the NREMT website shows that my certification will expire in March and seems as though I need to do continued education as well?? I'm confused, I have my certification and everything so why is the website saying this?
