Nurse Practitioner Specialties: What Are the Differences?
Nurse practitioner specialties determine which patient population you can treat once you're a practicing NP. There are several to choose from, and choosing the right one before you start a program matters — it can shape your future job opportunities.
Why Are NP Specialties Important?
Nurse practitioners are registered nurses who complete additional schooling to become an advanced practice registered nurse (APRN). APRN is the umbrella term that also includes:
To become an NP, you attend an advanced nursing program granting either an MSN or DNP. These programs are specific to patient populations — and that's what we mean by a specialty. Picking the right one matters: for example, if you complete an acute care program, you cannot sit for a family NP certification.
Family Nurse Practitioner (FNP)
FNP is the most common NP specialty, accounting for about half of all NPs — and for good reason: it's the most versatile certification. FNP programs focus on family medicine, spanning ages 0–100+, with a primary care emphasis. Specialty clinicals can be completed in the ER, hospitals, and various outpatient settings depending on the program.
While most FNPs work in outpatient primary care, many work outside it:
The downside: while your program gives you the base knowledge for these settings, most hands-on clinical experience is in primary care. That can leave you somewhat unprepared for areas like the ER, creating a learning curve. It makes it especially important to find a job with a thorough orientation and strong ongoing support from collaborating physicians and nursing staff.
Quick Note
I'm personally an FNP, and I've worked as an inpatient hospitalist as well as within the ER.
Adult-Gerontology Primary Care NP (AGPCNP)
The AGPCNP is similar to FNP but limited to patients over age 13. AGPCNPs often work in:
Adult-Gerontology Acute Care NP (AGACNP)
The AGACNP (or ACNP) is specialized to treat adults and geriatric patients in acute and critical care — primarily within the hospital, both ICU and general floor. They're also limited to patients 13 years or older. AGACNPs can work in:
ACNPs can also work the ER, but limited to patients 13+, which can limit job availability — though their acute-care training benefits them with emergent patients. Some programs offer dual FNP-ACNP certification, the most flexible option of all, but it requires additional schooling, clinical hours, and testing for both.
Emergency Nurse Practitioner (ENP)
The ENP is a newer certification with a handful of programs across the US. ENPs are certified to see patients of all ages in emergency and ambulatory settings (urgent cares, retail clinics, etc.). Training is specific to the ER and ER procedures — great preparation, but you'll be significantly limited on where else you can work.
An FNP with a minimum of 2,000 hours of qualifying experience can apply by portfolio and then sit for the ENP exam (see requirements). Otherwise, they attend an ENP program or complete an emergency-medicine fellowship. For a full breakdown, see the how to become an ENP guide.
Women's Health Nurse Practitioner (WHNP)
The WHNP focuses on women's primary care needs, including:
Depending on the program, this may be offered alongside a family or adult-gero certification. It gives great training specific to women's health, but limits you to that population unless you pursue a dual or post-masters certificate. Notably, this exam is offered not by the AANP or ANCC, but by the NCC (National Certification Corporation).
Psychiatric Mental Health NP (PMHNP)
The PMHNP is gaining popularity fast. It certifies NPs to treat psychiatric and mental health disorders across the lifespan, including conditions such as:
This specialty is specific — you won't work outside psychiatric mental health — but you can work inpatient psych, outpatient psych, or telehealth, which is increasingly popular.
Pediatric Nurse Practitioner (PNP)
The PNP certifies an NP to see patients from birth to 21 years old. Training and education are specific to the pediatric population, and you won't be able to leave that population without additional education.
Neonatal Nurse Practitioner (NNP)
The NNP works with neonates, infants, and toddlers up to age 2 — including those born prematurely.
Which NP Specialty Should You Choose?
Sometimes the choice is straightforward, and other times it's harder. Here's some general guidance:
Best if you're unsure where you'll work, want to work in multiple settings, or want primary care. Just expect a learning curve in non-primary-care settings.
Great if you want to work only with adults in primary care or outpatient specialty offices.
Great if you love the hospital, long-term care, or specialty offices with rounding privileges.
ENP for ER/urgent care; WHNP for women's health; PMHNP for psych; PNP for kids; NNP for neonates. These give focused, well-prepared training.
Keep in mind that many of these specialties (except neonatal) will also hire FNPs or AG-NPs depending on the state and facility — though jobs requiring you to see kids won't hire an AGNP. While FNPs used to be hired for some psych work, the PMHNP is becoming the standard (basic anxiety and depression are still within a primary care NP's scope). All specialties have similar lengths, costs, and clinical requirements; they differ mainly in the material taught and clinical experiences offered.
I’m glad that you mention that there are nurses that specialize in geriatric care. I’d imagine that it would be the same for doctors. Since my grandpa is turning 73, maybe we can find a geriatric doctor that can give him the care he needs.
Understanding the difference between a nurse practitioner and a regular nurse can help new students decide which path to go down. Thanks for sharing!
Agreed, thanks for your input! 🙂
It sure was interesting when you said that you will be given training and education that caters to the pediatric population when you decide to be a pediatric nurse practitioner. This is something that I will share with my 24-year-old niece who told me the other night about her plan to enroll herself in a nurse practitioner program next month. She has been noticeably too affectionate to kids, so I will ask her to consider your tips.
Knowing the distinction between a registered nurse and a nurse practitioner can help students choose the right profession. I am grateful for your contribution.
