Cost and program length vary depending on the school you choose. If you are interested in a particular CNA course in Arizona you need to contact the school or facility that is actually providing the training to find out but typical nursing assistant classes are approximately six weeks long. The cost can be up to $1000 but you can get reimbursed for that as well as the exam cost if you get a job in a long-term care nursing facility.
Some nursing homes do make offers of employment to their nurse aide graduates. Private schools and community colleges offer guidance and references for their students, but you must apply for jobs yourself. Once you complete the program you need to pass the CNA exam in order to obtain state certification. A certified nursing assistant job consists mainly of helping clients with activities of daily living in nursing homes, home health, and other facilities.
