How we research and review
Our editorial process is designed to produce useful licensing summaries that remain traceable to the authority responsible for the rule.
Last updated: August 24, 2026
Editorial purpose
Trade License Atlas reduces the time required to locate occupational-license information. Our guides explain the route in plain English while preserving the distinctions that matter: individual versus business licenses, statewide versus local authority, experience eligibility versus license issuance, and reciprocity versus a new application.
Source hierarchy
We prioritize sources in the following order:
- Official licensing-board and government-agency pages.
- Current statutes, administrative rules and government publications.
- Official applications, candidate bulletins, fee schedules and renewal instructions.
- Government-designated testing providers when they administer an official examination.
- Other sources only for context, never to override a responsible authority.
Commercial schools, insurers, software companies, lead-generation websites and general directories may help identify a research question, but they are not treated as final evidence for a licensing requirement.
Our publication workflow
- Define the scope. We identify the exact occupation, jurisdiction, license level and regulated activity.
- Locate the authority. We confirm which agency or board administers the credential and whether local rules also apply.
- Cross-check the route. We compare application, experience, training, examination, fee, insurance or bond, renewal and reciprocity materials.
- Write for decisions. We organize the answer around the choices a real applicant must make, not around keyword repetition.
- Link the evidence. Guides include direct official links and a visible source-review date.
- Review before publication. We check numerical claims, license names, caveats, internal consistency, links and formatting.
Dates, updates and changing rules
The “Official-source review” date shows when the cited source set was most recently checked for that guide. It is not a guarantee that an authority has made no later change. Agencies can update fees, forms, rules and testing arrangements without advance notice.
Material changes are incorporated as soon as they are identified and verified. A correction may update the text, table, metadata, visual summary and review date. Purely stylistic edits do not necessarily change the source-review date.
Corrections policy
We welcome specific corrections supported by current official evidence. Reports receive priority when they identify the page, disputed statement, responsible authority and direct source URL.
We investigate the primary material before changing a guide. If the evidence is ambiguous, we may add a caveat or contact the authority rather than present an assumption as fact. Significant corrections are made directly in the affected guide so future visitors see the current answer.
Local rules and professional judgment
A statewide credential does not always resolve permits, inspections, zoning, business registration, employment law or city and county requirements. We flag local variation when the official material indicates it, but no national guide can enumerate every project-specific decision.
Readers must confirm final eligibility and scope with the responsible authority. Our content is educational information, not legal advice or an official eligibility determination.
Technology and human accountability
We may use software and artificial-intelligence tools to help organize research, compare documents, detect inconsistencies, draft structured summaries or test page quality. These tools are not accepted as authoritative sources. Editorial responsibility remains with Trade License Atlas, and factual claims are checked against the cited official material before publication.
Editorial independence
Advertising, referral relationships and product partnerships are kept separate from licensing conclusions. Advertisers cannot purchase a change to an official requirement, remove a relevant warning or receive undisclosed favorable treatment. Sponsored or affiliate material will be identified where applicable.
Authorship and expertise
The Trade License Atlas Editorial Team byline identifies work produced under this policy. It does not imply that the writer is a government employee, attorney or credential holder in every occupation. When specialist review is obtained, the nature of that review should be stated rather than implied.
