The U.S. federal government requires a minimum of 75 hours of state-approved training for nursing assistants who work in nursing care facilities, according to the BLS. They also must pass a written competency evaluation, after which, successful candidates are awarded certification and become CNAs.
Nursing assistant programs can be completed in just a few weeks and generally include lab and clinical instruction. While enrolled in these programs, students will learn basic nursing and personal skills, clients' rights, and effective communication techniques. Use high school classes to prepare for the program.
