text: is it hard to become a cna.can they work anywhere else other then a nursing home? if yes where?   no, it's not that hard, about a 6 week class. in some states, you can "challenge" the test without taking the class. get a book and prepare though -- some of the questions on the test are very wierd.  besides nursing homes and rehab centers, hospital employ a lot of cnas. if you work for an agency, you may be able to get a private client.
