To become a licensed nurse practitioner, you need a graduate nursing degree from an accredited program, a passing score on a national certification exam in your population focus, and an advanced practice registered nurse (APRN) license from your state board of nursing. Beyond that, nurse practitioner licensing requirements usually include a separate prescriptive authority credential, a Drug Enforcement Administration (DEA) registration if you plan to prescribe controlled substances, and a National Provider Identifier before you can bill for care. The sequence is the same in every state; the paperwork and timelines differ.
Graduate Degree From an Accredited Program
No state will license you as an NP without a graduate nursing degree. You have two options: a Master of Science in Nursing, which runs about two years, or a Doctor of Nursing Practice, which takes closer to four. Either one qualifies you to sit for certification and apply for licensure, though DNP holders tend to have broader career options later.1American Nurses Association. What Is a Nurse Practitioner and How Do You Become One?
The program has to be accredited by the Commission on Collegiate Nursing Education (CCNE) or the Accreditation Commission for Education in Nursing (ACEN). State boards check this during the application review, and a degree from an unaccredited program will stop your file before anyone looks at the rest of it. The curriculum must cover advanced pharmacology, physical assessment, and pathophysiology, and your program must include at least 500 supervised direct patient care clinical hours in your specialty.2American Academy of Nurse Practitioners Certification Board. Statement on NP Students and Direct Care Clinical Hours
Choose a Population Focus Before You Enroll
Every NP program locks you into one population focus, and that choice determines which certification exam you can take, which state endorsements you qualify for, and which patients you can legally treat. The APRN Consensus Model recognizes six:3National Council of State Boards of Nursing. APRN Consensus Model
- Family/individual across the lifespan, the broadest scope
- Adult-gerontology, split into primary care or acute care tracks
- Pediatrics, also available in primary or acute care tracks
- Psychiatric/mental health across the lifespan
- Women’s health and gender-related care
- Neonatal, especially for critical care settings
Switching focus later means more graduate coursework and a new certification exam. Pick carefully.
Pass a National Certification Exam
After graduation, you have to pass a national certification exam before any state will process your license. Two bodies administer them: the American Nurses Credentialing Center (ANCC) and the American Academy of Nurse Practitioners Certification Board (AANPCB). Both are recognized by every state board of nursing, Medicare, Medicaid, and private insurers, so the choice comes down to format preference and price rather than professional standing.4American Academy of Nurse Practitioners Certification Board.

ANCC exam fees run $295 for American Nurses Association members and $395 for non-members, with a $140 non-refundable administrative fee baked into the price.5American Nurses Association. ANCC Family Nurse Practitioner Certification AANPCB charges $240 for members and $315 for non-members when applying online; paper applications add $50.6American Academy of Nurse Practitioners Certification Board. Fees Both tests cover diagnostic reasoning, treatment planning, and pharmacology within your population focus. Most candidates get results within a few weeks, and the certifying body sends verification directly to your state board.
Apply to Your State Board of Nursing
Your APRN license comes from the board of nursing in the state where you plan to practice. Gather the documents before you open the application; boards reject incomplete files rather than following up, and resubmitting adds weeks.
- A current, unrestricted RN license. The APRN credential sits on top of your RN license, so if the RN lapses, so does the APRN.
- Official graduate transcripts, sent directly from your program to the board.
- Certification verification, sent directly from ANCC or AANPCB to the board.
- Government-issued photo ID and your Social Security number.
- Criminal background check, typically through LiveScan or local law enforcement fingerprinting. The background check itself runs $50 to $90.
- Disclosures of any criminal history, malpractice claims, or discipline from other jurisdictions. Boards treat non-disclosure far more seriously than the underlying issue.
Most boards use online portals; a few still accept paper. Initial APRN application fees generally range from $85 to $500 depending on the state. Processing takes roughly four to eight weeks for a clean file. If you need to start work sooner, some states issue temporary practice permits to APRNs already licensed elsewhere, usually tied to a specific employer and limited to a set time period.
Prescriptive Authority Is a Separate Credential
Holding an APRN license does not automatically let you write prescriptions. Many states require a separate prescriptive authority application to the board of nursing. Some grant it with the license. Others require additional pharmacology coursework, a set number of supervised prescribing hours, or a formal collaborative agreement with a physician. Check your state board’s rules specifically for prescriptive authority rather than assuming the main license covers it.
DEA Registration for Controlled Substances
To prescribe anything on Schedules II through V, you need a DEA registration. New applicants file DEA Form 224 through the Diversion Control Division’s online portal.7Drug Enforcement Administration. Registration The practitioner fee is $888 and the registration lasts three years.8Federal Register. Registration and Reregistration Fees for Controlled Substance and List I Chemical Registrants
Before the DEA will process the application, you must complete at least eight hours of training on treating patients with opioid and other substance use disorders. The requirement comes from the Mainstreaming Addiction Treatment (MATE) Act and applies to new applicants and renewals. For NPs, the training has to come from an approved provider and cover the clinical use of FDA-approved medications for substance use disorders.9Drug Enforcement Administration. Opioid Use Disorder – MATE Act If your graduate program covered this within the past five years, that may already satisfy the requirement; confirm with your program.
National Provider Identifier
Anyone who bills Medicare, Medicaid, or submits HIPAA-covered transactions needs a National Provider Identifier, a unique 10-digit number that follows you throughout your career no matter where you work.10Centers for Medicare and Medicaid Services. National Provider Identifier Standard The application is free and runs through the National Plan and Provider Enumeration System (NPPES). You’ll pick at least one taxonomy code that matches your specialty and list your practice location.11NPPES. Apply for an NPI Apply as soon as your state license comes through, because you can’t bill without one and most employers will ask for it before your start date.
What Your License Actually Lets You Do Depends on the State
The license is the same credential everywhere, but the practice authority behind it is not. States fall into three groups:
- Full practice authority: you can evaluate patients, diagnose, order and interpret tests, and prescribe (including controlled substances) under the sole authority of the board of nursing, with no physician oversight.
- Reduced practice: state law requires a career-long collaborative agreement with a physician or other provider for at least one element of your scope.
- Restricted practice: state law requires career-long physician supervision, delegation, or team management.
Several full-practice states also impose a transition-to-practice period, where you work under a collaborative arrangement for a set number of hours before gaining independent authority. The hour requirements range widely, from around 1,000 in some states to over 4,000 in others. If you’re choosing where to practice, factor this in before you apply.
Practice is state-specific in another way too: if you see patients in more than one state, including by telehealth, you generally need a license in each state where your patients are located. An APRN Compact has been drafted to allow a single multistate license, similar to the existing Nurse Licensure Compact for RNs, but it is not yet active; it requires seven states to enact it and only four have done so.12APRN Compact.

Keeping the License Active
Your APRN license doesn’t stay valid on its own. Most states renew every two to three years, and renewal takes more than a fee. You’ll need to complete a set number of continuing education hours each cycle, with a portion (often 15 to 30 credits) specifically in advanced pharmacology if you hold prescriptive authority. Many boards also want proof of active practice, with some requiring at least 1,000 clinical hours over a five-year window.
Your RN license has to stay current the entire time. If it expires or gets suspended, the APRN becomes invalid along with it, regardless of where you are in the APRN renewal cycle.
Boards audit a percentage of renewals at random to verify CE compliance. If you’re pulled, you’ll need certificates showing the provider name, topic, contact hours, and date for each activity. Keep those records organized as you earn the hours, not after a notice arrives.
