CNA certification renewal is required in every U.S. state to keep your nurse aide registry listing active and legally work as a Certified Nursing Assistant. While the general framework is consistent — prove active employment, meet continuing education hours, and pay a renewal fee — the specific requirements vary significantly by state. Whether your renewal is coming up in 30 days or you are researching what happens if your CNA license lapses, this guide covers every step of the process so you stay current and compliant. Use the section links below to jump directly to what you need.
The Nurse Aide Registry in each state is a federally mandated database that tracks active CNAs under the Omnibus Budget Reconciliation Act of 1987 (OBRA '87). Federal law requires states to maintain a nurse aide registry and ensure that all individuals providing direct patient care in Medicare- and Medicaid-certified facilities hold a current, active listing. Renewal exists to confirm that CNAs remain actively working in the field and maintaining competency — not simply holding a credential they earned years ago.
If your registry listing becomes inactive or expires, you are legally prohibited from working as a CNA in any Medicare- or Medicaid-certified facility until reinstatement is complete. Many private-pay facilities follow the same rules. Understanding renewal timelines is just as important as knowing how to earn your CNA certification in the first place — because letting it lapse can mean starting the process over entirely.
The renewal period is almost universally set at 24 months, meaning you must renew every two years. A small number of states use different intervals (Oklahoma uses 1 year; several states align renewal with state fiscal year cycles), but two years is the national standard. Your renewal deadline is tied to your original certification date or your last renewal date, not to your current employer's hire date.
Federal law requires a minimum of 8 hours of paid nursing-related work during the 24-month renewal period. Most states adopt this federal floor, though some require more (California requires 48 hours of work in the 24 months). The work must be paid — volunteer hours do not qualify. Qualifying work includes direct patient care as a CNA, home health aide work, and in some states, related roles such as patient care technician or medical assistant. You will need to document your employer name, dates of employment, and supervisor contact information. Always keep pay stubs or employment verification letters in case your state registry requests documentation.
Continuing education (CE) requirements vary by state from zero hours (states that only require work verification) up to 48 hours per renewal cycle. Most states fall in the 12–24 hour range. California requires 48 CE hours per two-year period; Texas requires 24 hours with mandatory topics including abuse prevention and infection control. CE courses must be taken through state-approved providers — not all online courses qualify. Topics frequently required by state mandate include resident rights, infection control, mental health and dementia care, and abuse/neglect recognition. The CNA CEU credits guide covers approved providers and how to track your hours.
Renewal fees are set by each state's nurse aide registry and typically range from $0 (a few states charge nothing) to $75 for standard renewal. Late renewal — submitting after your expiration date but within a grace period — may incur additional fees of $25–$100. Payment is generally made directly through the state registry's online portal when submitting your renewal application. Some states still accept checks by mail. Always renew through the official state registry portal; third-party 'renewal services' that charge excessive fees are not required and are often scams. Verify your state's official registry URL through your state's Department of Health website.
If your certification has lapsed past the renewal deadline and any applicable grace period, reinstatement requirements escalate. Most states require a skills competency evaluation — a proctored skills check performed at a state-approved testing site. Some states (notably California and New York) allow reinstatement through skills evaluation alone if the lapse is under a certain threshold (often 2–5 years). If your listing has been inactive for more than 5 years in most states, full retesting — both the written knowledge test and the clinical skills evaluation — is required, the same process as initial certification. Avoid this outcome by setting calendar reminders 90 days before your renewal deadline.
Because nurse aide registries are administered at the state level, renewal requirements differ enough that you must always verify requirements directly with your state's registry. Do not rely solely on what a coworker tells you or what you remember from your last renewal — requirements change, and what applied two years ago may not apply today. The single most important step is to look up your listing on your state's official nurse aide registry website to confirm your current expiration date and the specific documents required.
For state-specific listings and contact information for each nurse aide registry, use the CNA license renewal lookup tool, which links to every state registry portal. You can also verify your license status, check your expiration date, and confirm your employer's verification is on file through this resource.
If you discover your certification has lapsed, act immediately — do not wait. The longer you delay, the more likely you are to fall past any grace period your state offers and face full reinstatement requirements. Here is the priority order of steps to take:
CNAs who are building a long-term career in healthcare should treat renewal as a routine administrative task, just like renewing a driver's license. The CNA career paths available to experienced CNAs — from hospital jobs to travel assignments — all require an active, current registry listing. Letting your certification lapse limits every opportunity available to you.
