There is no additional education or certification required
beyond basic licensure as an RN or LPN; however, different facilities have different standards. Some will hire new grads, some require experience in another nursing setting; some require BSNs, some don't; some use LPNs (in addition to RNs), some don't. A degree in psychology has almost nothing to do with practicing psychiatric nursing
, and would not particularly benefit anyone in nursing. Lots of facilities hire people with BAs in psychology to work as techs
, and be supervised by the nurses. Nursing school
would teach you what you need to know about psychiatric nursing to get started in the field.
Best wishes for your journey!
