Where Mental Health Nurses Work

You'll find mental health nurses in hospitals and health systems, clinics, inpatient treatment centers, private psychiatric and psychological practices, and government settings like correctional facilities and military bases. Some work in disaster relief or other humanitarian care.

Inpatient mental health settings: administer treatments and medications, lead or assist group sessions, and conduct tests and assessments under medical supervision.

Hospitals: run mental health assessments, administer treatments and medications, update records, and educate patients and families on conditions and treatments.

Substance use treatment settings: conduct assessments under supervision, lead or assist group sessions, monitor patient conditions, educate patients and families, and run followup interviews.

How to Become a Mental Health Nurse

Start by earning a registered nurse (RN) license. You'll need an associate degree in nursing (ADN) or a bachelor of science in nursing (BSN) to qualify for the National Council Licensure Examination (NCLEX-RN).

An ADN takes two years; a BSN takes four and covers more ground in greater depth. If you plan to earn a master's and become a nurse practitioner, the BSN is the better investment, though RN-to-MSN bridge programs exist if you start with an ADN. After graduating, pass the NCLEX-RN and apply for a state license.

Like other new nurses, entry-level mental health nurses get extensive on-the-job training. Once you have experience, many pursue certification such as the American Nurses Credentialing Center (ANCC) Psychiatric-Mental Health Nursing Certification (PMH-BC).

Certification isn't a legal requirement the way RN licensure is, but it demonstrates your knowledge and experience, and many employers require or strongly prefer it for higher-level roles.

If you want more autonomy and earning potential, look at becoming a psychiatric nurse practitioner. PMHNPs can diagnose and prescribe treatment, which means more independence and usually higher pay.
