I took the CNA course in Colorado with Nursing and Therapy Services of CO. I worked for one year as a CNA but then we moved to VA(we're a military family). I have not worked for 2 1/2 years as a CNA. We are now living in NC and I was wondering if anyone knows whether I need to take another course (again) or if I can just take the State exam and Skills test to become certified again? My certification lapsed in January 2012. Thanks for any help you can give! Beth
