My girlfriend is already a caregiver who has worked at a facility for over 2 years, is it possible for her to take the CNA test instead of enrolling in a class or must she enroll beforehand? She meets the requirements of a CNA already, and does the job as if she really is, all she wants is to be certified. She will be moving to New Jersey from Oregon. Please, could you help me by providing all the information necessary to help her gain her CNA certification?
