Step-by-step guide to locate your state registry, check status, and renew on time.

A nurse aide registry is a state-run database that lists every certified nursing assistant's current standing, and federal law requires long-term care employers to check it before a hire is finalized. That single fact explains why so many CNAs feel a jolt of panic the night before a job interview, unsure whether last year's address change or a missed renewal notice quietly flipped their status to inactive.
The fix costs nothing. Every state maintains a lookup tool, and cnaclasses.org compiles direct links to each one alongside plain-English renewal timelines by state.
Still, a five-minute check now beats a stalled job offer later.
Some CNAs think of their certification card as proof enough of their credentials, while others understand that the real verification lives in a centralized database. The CNA registry is that database, and knowing how it works protects both your career and your ability to land jobs quickly.
The CNA registry is an official record system that each state maintains to track every nurse aide who has completed the CNA training curriculum and passed competency evaluations. When you earn your certification, your name, certificate number, certification date, and status get entered into this database. The registry serves as the single source of truth for anyone who needs to confirm that you are legally authorized to work as a CNA.
Most state registries allow searches by name, certificate number, or both. This makes it straightforward for employers, licensing boards, and even CNAs themselves to verify active status within minutes.
Healthcare facilities do not simply take your word that you hold valid credentials. Before extending a job offer, they run your name through the state registry to confirm your certification is current and that no negative findings appear on your record. State health departments also use the registry during inspections to ensure facilities employ only properly credentialed staff.
This verification step protects patients and holds the entire long-term care industry to consistent standards.
The Omnibus Budget Reconciliation Act of 1987 (OBRA) established the federal mandate requiring every state to maintain a Nurse Aide Registry. Under this law, anyone working as a nurse aide in a Medicare or Medicaid certified nursing facility must appear on their state's registry with active status. OBRA also requires that registries document any substantiated findings of abuse, neglect, or misappropriation of property, which follow a CNA across state lines even without a CNA licensure compact.
Understanding this framework helps you see the registry not as bureaucratic paperwork, but as the foundation of your professional standing.
Every state maintains its own nurse aide registry, and because CNA state requirements vary, each portal has slightly different search requirements , so knowing what information you need before you start will save you time and frustration.
All CNA registry lookups should be performed through official state-operated websites or state-approved vendor platforms. These are typically hosted on .gov domains or on sites run by contracted testing organizations such as Prometric or Credentia. A few confirmed examples of official portals include:
For states not listed here, cnaclasses.org maintains a directory of links organized alphabetically from Alabama to Wyoming. Always confirm you are on an official or state-approved site before entering personal information.
Most registries let you search by name, certification number, or both. Beyond that, requirements vary:
A small number of states require you to create a login or use a contracted vendor portal rather than offering open public search. New York, for instance, routes online lookups through Prometric, and some Southern states use Alliant Health Solutions as their verification platform.
If your state's portal asks for a certification number, omit any trailing letters (such as "E" or "R") that may appear on older documents. When a basic search returns no results, try alternate name spellings or contact the registry office directly by phone or email. Minnesota's registry staff, for example, can assist when online searches come up empty. Keeping your certificate number, legal name, and last four SSN digits handy before you begin will make the process quick and painless.
Because each state's required search fields vary slightly, use the directory table to check your state's portal and exact fields before you begin. The four-step process below applies to most official nurse aide registries.

According to the Bureau of Labor Statistics, more than 1.35 million nursing assistants were employed across the United States as of May 2023, and virtually every long-term care employer verifies a candidate's status on the state nurse aide registry before extending a job offer. Your registry record is your professional identity.
CNA registries do not use one national status vocabulary. However, most states separate records into three families: current, stalled, and disciplinary.3
A status that sounds mild in one state may be serious in another. Inactive usually points to a paperwork or work-hour gap, not a discipline case. Expired generally means the certification period ended or the state's lookback window closed without renewal. But the exact trigger differs by state.
Texas uses "Active" and "Expired" as primary labels, with expiration tied to 24 months without paid services2. Missouri lists "Active CNA Status," "Inactive," and "Expired CNA Status"1. Pennsylvania lists "Active," "Inactive (Lapsed)," and "Findings"3. California has used active, denied, suspended, and revoked statuses since March 1, 20233. There is no fixed national dictionary.
If your record says something other than active, do not panic. Open your state's official nurse aide registry page and read its definitions. In some states, inactive can be fixed by submitting proof of recent nursing-related work. In others, expired status may require retraining or a CNA skills exam. The exact wording on your state registry page is the authority.
An inactive status usually means your renewal is late or your state has not received proof of the required continuing education or work hours. You may still have a short window to fix the problem, but you are generally not authorized to work as a CNA until the registry shows an active status again. An expired status is more serious: in many states, nurse aides who do not renew or document qualifying work are removed from the registry after 24 months. Once that happens, you cannot legally return to work until you complete the state's reactivation steps.
Begin by checking the exact notation on your state's registry lookup record. The record may show you as active, inactive, expired, lapsed, or not listed. Each label drives a different next step, so do not assume that inactive and expired mean the same thing. If your contact information has changed, update it with the registry right away; renewal and reactivation notices usually go to the address or email on file, and missing those notices is what pushes many aides into expired status.
Reactivation rules differ by state. California offers a limited reactivation path: a lapsed certificate can be renewed within 2 years, but you must retrain and pass the Competency Evaluation Examination. Oregon credits recent direct-care experience, you can qualify by documenting 400 hours of work within the last 2 years, or you may need to complete the state's competency exam within 1 year. Connecticut requires retesting when certification has been inactive for 24 months or more, using a written exam. South Dakota also requires retesting with the knowledge exam when you cannot document recent work hours or continuing education.
If your state requires retraining or retesting, compare approved CNA programs before you re-enroll, and pay attention to cna exam pass rates by school. In some states, a refresher course may be enough; in others, you must complete a full program. Always ask the registry for a written description of your required path before you pay for training, because reactivation requirements can change and may depend on how long you have been inactive.
Renewal requirements for CNAs vary dramatically from state to state, making it essential to verify your specific obligations well before your nursing assistant certification expires.
Most states operate on a two-year renewal cycle, though some require annual renewals while others extend to three years. Your state registry will list your exact expiration date, typically tied to your original certification date or a standardized renewal window. Missing this deadline can result in your status changing to inactive or expired, which may require retesting to restore.
Nearly every state requires CNAs to demonstrate active employment in nursing-related duties during the renewal period. The minimum hours vary considerably. Some states accept as few as 8 hours of compensated work, while others require 16, 24, or more hours within a specific timeframe. Volunteer work typically does not count toward this requirement. If you have not worked as a CNA during your renewal period, many states require you to retake the competency examination rather than simply renewing.
This is where state requirements diverge most significantly. Several states impose no continuing education requirement at all, allowing CNAs to renew based solely on work hours and fees. Others mandate 12, 24, or even 48 hours of approved continuing education. Michigan, for example, requires 12 hours of continuing education annually as of 2026, with an attestation confirming completion during the renewal period. The state renewal fee in Michigan is $40. States with higher CE requirements often accept a combination of in-service training, online courses, and employer-provided education.
Renewal fees range from no charge in some states to over $100 in others. Many states now offer online renewal portals, allowing you to complete the process in minutes. However, certain states still require paper applications mailed to the registry or health department. California CNAs who have let their certification lapse must pass the Competency Evaluation Examination within two years of the expiration date through a state-approved testing vendor.
Locate your state's official nurse aide registry page to confirm your renewal cycle, work hour minimum, CE requirements, fee amount, submission method, and other CNA certification requirements. Check at least 60 days before your expiration date to allow processing time.
How do you make sure your state nursing aide registry can actually reach you when renewal time comes around?
Keeping your mailing address, phone number, and email current in your state's CNA registry is one of the simplest steps you can take to protect your certification. When the registry sends renewal notices to an outdated address, those notices bounce back. In many states, a returned notice triggers an automatic status change to "inactive" or "lapsed," even if you completed all other renewal requirements on time. This means an address you forgot to update could cost you your active certification status and your ability to work.
The process for changing your contact details varies by state, but most registries follow one of two paths:
Check your state's nurse aide registry website for specific instructions. If you are unsure which method your state uses, calling the registry directly is the fastest way to confirm.
Update your registry record as soon as you move, change phone numbers, or get a new email address. Do not wait until your renewal period. Delays can mean missed renewal notices and unnecessary lapses in your status.
If a renewal notice is returned as undeliverable, many states automatically flag your record. Even if you renewed on time, you may need to submit additional documentation or contact the registry to restore your active status. Keeping your information current avoids this hassle entirely.
A missing CNA record or a single typo can keep you from landing your first CNA job, but the correction process is rarely as complicated as it looks when you know what proof each state accepts. The real risk is assuming the error will resolve itself. Most registry mistakes require a written request, supporting documents, and a follow-up to confirm the change was made.
Compare your registry listing against your government-issued ID, Social Security card, and training completion certificate. A transposed digit or a name entered under a different version is often the whole issue. Do not guess at what might be wrong; request the exact field that the registry has on file if the online lookup does not show it.
States handle corrections differently, but most require a written request plus legal proof. In Maryland, the Maryland Nurse Aide Registry asks users to submit a Correction Form through the Credentia platform and upload a marriage certificate, divorce decree, or other official document. Tennessee requires a photocopy of a legal document for name changes.1 Minnesota requests a copy of your Social Security card when the SSN is wrong.2 Michigan accepts email requests that include your name, MiLogin username, phone number, and a brief description of the problem.3 Pennsylvania uses a Correction Form for name, date of birth, or SSN updates, and its registry line is 800-932-0939 option 1. Massachusetts uses a personal information amendment process through its licensing site.4 Include a direct statement of exactly what needs to change, and keep a copy of everything you send.
Ask the registry staff to perform a search if you do not see your listing. Before you call, gather your training completion certificate, exam results, photo ID, and any verification from other states where you have been certified. Maine, for example, asks applicants for current photo ID and verification from all states where they are certified.5 If the record still cannot be located, ask for the next step in the escalation process rather than starting a new application from scratch. Minnesota's registry email is [email protected] if you prefer to start in writing.2
For hiring managers and staffing coordinators, the CNA registry is the single most important pre-hire check you will run. A candidate's resume and certificate copy are not enough: federal and state rules require you to confirm active status directly through the official registry before that person provides care.
Most states follow a similar pattern, even though the portals differ:
Many employers also run OIG and GSA exclusion screenings alongside the registry lookup to catch federal healthcare program bans that a state registry will not show, so they should also review CNA background check requirements.
Several states go beyond the public lookup and require employers to use a dedicated tool:
Prometric, which administers testing and registry functions in many states, publishes specific forms for these tasks, including an Employment Verification Form, a Private Duty Employment Verification Form, and an Employer Renewal Approval Request Form.
There is no single nationwide portal that lets an employer batch-verify CNAs across state lines. Each state maintains its own registry, so multi-state operators need a checklist covering every jurisdiction where they hire. Disciplinary detail is also uneven: some states display findings directly in the public lookup, while others require a separate written request to obtain the full record.
