- Prescriptive Authority
- Legal permission granted by a licensing board that allows an NP to prescribe medications, including controlled substances, within defined limits.
- Collaborative Practice Agreement (CPA)
- A written agreement between a nurse practitioner and a supervising or collaborating physician that defines the NP's practice parameters where state law requires physician oversight.
- Full Practice Authority (FPA)

- Credentialing
- The process by which a healthcare facility verifies an NP's licenses, certifications, education, and work history before granting clinical privileges.
- Clinical Privileges
- Specific authorized activities an NP may perform within a particular healthcare facility, granted after credentialing and subject to periodic renewal.
- Population Focus
- The patient population an NP is licensed and trained to serve — such as family/individual across the lifespan, adult-gerontology, pediatrics, or psychiatric-mental health.
- National Certification
