CEUsForFree.com lists multiple websites and online organizations which provide free Continuing Education Unit online classes for registered nurses. Nurse.com hosts a lengthy page full of free CEU courses for RNs, and NurseCEU.com contains a catalog of over 1000 free CEU courses which are provided online and at multiple physical locations.
Classes for continuing credits on the sites above are listed by category of nursing specialty primarily. Searching for classes by specialty will not separate the free classes from fee-required classes, however.
An RN looking for free classes exclusively must search in the Free classes group first, and then narrow the search by category within the Free group.
