Sources & Methodology

1. Our Editorial Mission for Sourcing

Every fact on a state page must be traceable back to a primary, authoritative source — almost always the state Board of Nursing’s own publication, the state’s Nurse Practice Act, or NCSBN’s published material. If we can’t show where something came from, we don’t publish it. That principle is the foundation of every other process on this page.

2. Source Hierarchy — Six Tiers

Not all sources are equal. We rank them by authority and start at the top, moving down only when a higher-tier source doesn’t address the question:

3. Tier 1 — State Board of Nursing Websites

The state board’s own website is the authoritative source for everything specific to that state — license verification URLs, fee schedules, CE rules, renewal cycles, and discipline databases. Examples we reference (each verified live):

• California Board of Registered Nursing (BRN, RNs): rn.ca.gov
• California Board of Vocational Nursing & Psychiatric Technicians (BVNPT, LVNs): bvnpt.ca.gov
• Texas Board of Nursing (RN/LVN/APRN): bon.texas.gov
• Florida Board of Nursing: floridasnursing.gov
• New York Office of the Professions — Nursing: op.nysed.gov/professions/nursing
• Illinois Department of Financial & Professional Regulation (IDFPR) — Division of Professional Regulation: idfpr.illinois.gov
• Pennsylvania State Board of Nursing: pa.gov — State Board of Nursing
• Massachusetts Board of Registration in Nursing (BORN): mass.gov — Board of Registration in Nursing
• Ohio Board of Nursing: nursing.ohio.gov
• Michigan Department of Licensing and Regulatory Affairs (LARA) — Board of Nursing: michigan.gov/lara
• Georgia Board of Nursing (Secretary of State Professional Licensing Boards Division): sos.ga.gov/index.php/licensing
• Washington State Department of Health — Nursing Commission: doh.wa.gov
• Arizona State Board of Nursing: azbn.gov

4. Tier 2 — State Nurse Practice Acts and Administrative Codes

For the underlying legal framework — license types, scope of practice, discipline grounds, and appeal rights — we reference each state’s Nurse Practice Act and corresponding administrative code:

• California — Nursing Practice Act, Business & Professions Code §§2700 et seq. (RNs); §§2840 et seq. (LVNs)
• Texas — Nursing Practice Act, Texas Occupations Code Title 3, Subtitle E, Chapter 301 (RN/LVN); Chapter 304 (Nurse Licensure Compact)
• Florida — Nurse Practice Act, Florida Statutes Chapter 464
• New York — Education Law, Title VIII, Article 139 (Nursing)
• Illinois — Nurse Practice Act, 225 ILCS 65
• Pennsylvania — Professional Nursing Law, 63 P.S. §211 et seq.; Practical Nurse Law, 63 P.S. §651 et seq.
• Massachusetts — General Laws Chapter 112, §74–§81C
• Ohio — Ohio Revised Code Chapter 4723 (Nurses)
• Michigan — Public Health Code, Article 15 (Occupations), Part 172 (Nursing)
• Georgia — Official Code of Georgia Annotated (O.C.G.A.) §43-26 (Registered Nurses); §43-26-30 et seq. (LPNs)

State statutes are typically published at each state’s official legislative site (e.g., leginfo.legislature.ca.gov for California, statutes.capitol.texas.gov for Texas, leg.state.fl.us for Florida). We link directly where the state publishes a stable URL.

5. Tier 3 — NCSBN Published Material

The National Council of State Boards of Nursing (NCSBN) at ncsbn.org is the membership organization for state boards. It does not issue licenses, but it administers the NCLEX through Pearson VUE, runs the Nursys national license database, and maintains the Nurse Licensure Compact. We cite its material for cross-state confirmation:

• Nurse Licensure Compact (NLC) member-state list and pending implementations
• Nursys at nursys.com — national license verification database
• NCLEX program documents — Test plans for NCLEX-RN and NCLEX-PN, candidate handbook, retake rules
• NCSBN’s directory of state boards — the cross-check we use to confirm we’re linking to the right official board

6. Tier 4 — Specialty Body Publications

For APRN role definitions, scope-of-practice frameworks, and specialty-certification context, we cite the relevant specialty body’s published material:

7. Tier 5 — NCSL and HRSA

The National Conference of State Legislatures (NCSL) at ncsl.org tracks state legislation across all 50 states; useful for confirming statutory changes that affect nursing scope of practice, CE mandates, or NLC adoption. The Health Resources and Services Administration (HRSA) at hrsa.gov publishes nursing workforce projections and shortage-area designations relevant to context — useful for understanding why a state may have introduced compact-state status, expanded APRN scope, or revised CE topics.

8. Tier 6 — Reputable U.S. Press and Academic Research

For background on a state’s nursing landscape, recent legislative changes, or policy debates, we reference reputable U.S. healthcare press (Modern Healthcare, Kaiser Health News, Health Affairs blog, Stat News), nursing-specific publications (American Journal of Nursing, Nursing2026, Nurse.org coverage), and peer-reviewed research from U.S. nursing and health-policy journals. Press and academic sources are never the sole source for a current portal URL, fee, or CE requirement. Anything time-sensitive comes from Tier 1, 2, or 3.

9. URL Verification — How We Stop Broken Links

1. Manual click-through. Every external link is clicked by an editor before publication. We confirm the page loads, the destination matches the topic, and the URL is the canonical one.
2. Official-domain confirmation. State board sites are confirmed against NCSBN’s board directory and the state’s own government portal to ensure we’re linking to the official board, not a third-party data aggregator with a similar name.
3. Content match. The destination page must actually be the page we describe. A “license verification” link that lands on a generic board homepage doesn’t pass — we link to the actual lookup tool.
4. HTTPS preference. Where the source publishes both, we link to HTTPS.
5. Live verification test. For Tier 1 portals, we run a sample license verification (using a board-published test license or a known public licensee) to confirm the workflow loads and returns the expected fields.
6. Quarterly re-verification. Every external link on every page is re-checked at least quarterly.
7. No Google Search fallbacks. If we can’t verify a state’s specific portal URL, we don’t link to a Google Search results page as a substitute. We mark the section as “URL not yet verified” or omit it.

10. Fact-Checking Workflow

1. Drafter pulls facts from the state board’s website, the state Nurse Practice Act, and NCSBN’s compact-state list. Each fact gets a source note.
2. Editor reads the source pages in full, including any “this year’s CE topics” notices, NLC implementation announcements, or scope-of-practice updates.
3. Editor cross-checks the board structure — single board vs split board (California BRN/BVNPT, etc.), agency umbrella (Office of the Professions, IDFPR, LARA, Secretary of State).
4. Sample license verification on the Tier 1 portal to confirm the workflow.
5. CE rules cross-checked against the state administrative code and any board-published guidance documents.
6. NLC status verified against NCSBN’s current member-state list — this changes periodically as states join.
7. APRN scope cross-referenced against AANP’s annual state practice environment publication.
8. Second editor reviews the page end-to-end before it goes live.
9. “Last reviewed” date is set to the publication date.

11. The Two-Source Cross-Reference Rule

Time-sensitive facts must be confirmed by two independent sources before they go on a page. Acceptable combinations:

• The state board’s own page and the state Nurse Practice Act (where the act sets the rule)
• The state board’s own page and NCSBN (for compact-state status, NCLEX administration, Nursys)
• The state board’s own page and AANP (for APRN scope-of-practice classification)
• The state Nurse Practice Act and NCSL legislative tracking (for recent statutory changes)

If two sources disagree, we go with the more authoritative one for the type of fact: the state board for portal mechanics and board-set procedures; the state statute for license types and scope-of-practice; NCSBN for compact membership and NCLEX administration.

12. Update Cycles — Aligned to the U.S. Nursing-Regulation Calendar

13. Citation Standards

• External links open in a new tab with rel="noopener" for security
• Affiliate links use rel="nofollow noopener sponsored" per FTC endorsement guidance
• Primary citations link directly to the state board page, statute section, or NCSBN page in question
• Statutory references use the standard state citation format (e.g., Bus. & Prof. Code §2700, Tex. Occ. Code §301.252, F.S. §464.012, 225 ILCS 65/55) and link to a stable text source where available
• Last-reviewed dates appear on every state page so readers can judge freshness

14. What We Don’t Use

• CE-mill marketing pages. Many continuing education resellers publish blog posts about state CE rules. They’re often months out of date and aren’t the issuing authority. The state board’s CE page is the source.
• NCLEX-prep marketing pages. NCLEX-prep companies have a commercial interest in describing the exam in particular ways. We use NCSBN’s published test plans and the state board’s eligibility rules — not vendor copy.
• Anonymous nursing blogs. Even when factually accurate, anonymous content can’t be verified or held to account.
• Wikipedia as a sole source. Useful for orientation, never as the sole basis for a fact on a state page.
• Generic AI-generated content from other sites. We don’t republish or paraphrase content we can’t trace to a primary source.
• Commercial nurse-staffing aggregators. They aggregate state-board data for hiring purposes; the state board itself is the authoritative source.
• Out-of-jurisdiction guidance applied across states. Texas Occ. Code §301 doesn’t apply in California; California’s BVNPT split doesn’t apply in Texas. We treat each state’s framework separately.
• Wayback Machine snapshots in place of current pages. Useful historical reference; never a substitute for the board’s current portal.
• Social media posts from individuals or unofficial accounts, regardless of follower count.

15. Reader Contributions and Corrections

Readers are an important part of our verification system. Nurse-attorneys, credentialing professionals, academic faculty, and practicing nurses who use these portals daily often spot inconsistencies before our quarterly review catches them. If you spot a discrepancy — a portal redirected to a new URL, a CE rule that’s been amended, a fee that’s been raised, an NLC status that’s changed — please email info@boardofnursings.org with subject line “Correction” and the URL of the page in question. The full corrections workflow is on the Editorial Policy page.

16. Audit Trail and Openness

Where a journalist, researcher, or credentialing professional needs to verify how we sourced a particular page, we make our editorial notes available on request. Email us with the URL of the page and the specific factual claim you want to trace, and we’ll respond within seven business days with the underlying source links and editorial notes. Transparency is a feature, not a cost.
