As long as you attended a board approved school of at least 120 hours, you may apply for a CNA license from the Arizona State Baord of Nursing.
You can make application on line or contact them to discuss your transfer in person.
You may have to challenge the state licensing exam. A determination is made with your application.
Only original documentation is accepted. Make sure when you send any documents, to retain notarized copies for your records, incase the orginals get lost.
