There are no CNA or LPN certification programs offered purely online, as of 2015. Institutions offering these programs online liaise with local facilities from which students can gain clinical experience. Online CNA classes offer foundational knowledge in nursing but do not award academic credit.
Popular online CNA programs include Medical Terminology, Health Issues in Public Health, Principles of Human Nutrition, and Patient Safety and Medical Errors. Refresher courses are available online for LPNs who had left the nursing profession. Practicing nurses wishing to advance can also take LPN to Bachelor of Science in Nursing degrees online. LPN to Registered Nurse classes are also available online.
