Both are ANCC psychiatric-mental health credentials, but at very different
levels of practice. The short version: PMHNP-BC is the advanced practice (nurse practitioner)
certification, while PMH-BC certifies registered nurses in psychiatric-mental health nursing.

Which one applies to you?

  • PMHNP-BC if you’ve completed a graduate nurse practitioner program and want to
    diagnose and prescribe as a psychiatric NP.
  • PMH-BC if you’re a registered nurse who wants to certify your expertise in
    psychiatric-mental health nursing without the NP scope.
  • They’re a career sequence for some: an RN may earn PMH-BC, then later complete a
    PMHNP program and pursue PMHNP-BC.

Whichever you’re preparing for, timed, scenario-based practice is the way through.
