To get a caregiver license, you complete a state-approved training program, pass a two-part competency exam, and clear a criminal background check. The whole process usually takes four to twelve weeks. Federal rules set a floor of 75 training hours for Certified Nursing Assistants and Home Health Aides, but most states require more, and the credential you pursue depends on whether you want to work in a clinical facility, in someone’s home, or in a non-medical support role.
Pick the Right Credential First
Three main credentials cover most caregiving work, and they aren’t interchangeable. Choose before you pay for training, because programs are built around a specific credential.
A Certified Nursing Assistant (CNA) works under a registered nurse, usually in a hospital, nursing home, or rehabilitation center. CNAs record vital signs, assist with catheter care, and help patients move safely. It’s the most common entry point into healthcare.
A Home Health Aide (HHA) does similar hands-on work in the patient’s home: bathing, medication reminders, light health monitoring, help with daily activities. Federal rules let an active CNA qualify as an HHA without separate training, so many people earn the CNA first and move into home health later.
A Personal Care Aide (PCA) handles non-medical support: meal prep, errands, housekeeping, transportation. Because PCAs don’t perform clinical tasks, training requirements are lighter and some states don’t require formal licensure at all.
Some states also offer a Certified Medication Aide (CMA) credential that lets a CNA administer certain prescribed medications under nurse supervision. It requires extra coursework on drug classifications, side effects, and safe administration. Not every state recognizes the role, so confirm your state offers it before paying for the training.
Who Can Apply
There is no single federal age minimum. States set their own, and the range is wider than people expect: some allow applicants as young as 16, others require 18. Most programs want a high school diploma or GED, though a few states will enroll you without one if you can demonstrate basic reading and math.
You’ll need to pass a criminal background check. Most states fingerprint applicants and run records through both state and federal databases. Fingerprinting and screening generally run $30 to $150.
Health screenings are standard. Expect to show a recent tuberculosis test, and often proof of current immunizations. You’ll be working with vulnerable people, and states take communicable disease screening seriously.
Training Hours and What They Cover
Federal regulations set the baseline every state must meet or exceed. Under 42 CFR 484.80, Home Health Aide training must total at least 75 hours, with at least 16 hours of classroom instruction and at least 16 hours of supervised practical training with patients under a registered nurse.1eCFR. 42 CFR 484.80 – Condition of Participation: Home Health Aide Services CNAs have a parallel requirement under 42 CFR 483.152: at least 75 clock hours, including at least 16 hours of supervised practical experience, covering basic nursing skills, infection control, safety, and residents’ rights.2eCFR. 42 CFR 483.152 – Requirements for Approval of a Nurse Aide Training and Competency Evaluation Program
Most states go well above the floor. California and Delaware require 150 hours. Maine requires 180. Missouri requires 175. Even less restrictive states often land around 100 to 120. Check your state’s requirement before enrolling, because hours completed in an unapproved program won’t count.
Training must happen through a state-approved program: a community college, vocational school, hospital-based program, or health department course. Classroom instruction covers anatomy basics, infection prevention, nutrition, emergency procedures, patient communication, and legal topics like residents’ rights and abuse prevention. The clinical portion puts you in a facility or lab setting practicing vital signs, bathing and transfers, positioning, and basic hygiene care. An instructor must sign off that you’ve demonstrated competence in each skill.
Standard CNA programs run four to eight weeks; accelerated versions can finish in three or four. Programs built around higher state hour requirements take longer. Expect tuition of roughly $400 to $1,700, plus $100 to $250 for textbooks and supplies. Some employers, particularly nursing homes with staffing shortages, will pay your training in exchange for a work commitment after certification.
The Competency Exam
The competency evaluation has two parts: a written or oral knowledge exam, and a hands-on skills demonstration. Most states contract with Prometric, Pearson VUE, or Headmaster; about a dozen run their own testing programs.
The written portion is usually multiple choice and covers infection control, patient safety, communication, body mechanics, and residents’ rights. The skills portion is where most people stumble: a nurse evaluator watches you perform a set of randomly selected care tasks on a patient or mannequin — measuring vital signs, assisting with a bed bath, demonstrating proper hand hygiene, repositioning a patient. The evaluator must be a registered nurse with at least one year of experience caring for elderly or chronically ill patients.
Combined exam fees generally run $125 to $200. One detail that catches people off guard: if you’re already employed at a facility or have a job offer from one when you start the evaluation program, federal law prohibits the facility from charging you for any portion of the exam.3eCFR. 42 CFR 483.156 – Registry of Nurse Aides If you get hired within 12 months of completing the program, the state must provide prorated reimbursement of your evaluation costs.
Pass both portions and you receive a registry number. Your name goes on your state’s nurse aide registry, which every state is required by federal law to maintain as the official record of qualified nurse aides.3eCFR. 42 CFR 483.156 – Registry of Nurse Aides Employers verify your active status through this registry before hiring.
If You Fail
Federal law guarantees you at least three attempts. States can allow more but not fewer.4eCFR. 42 CFR 483.154 – Nurse Aide Competency Evaluation You’ll be told which section you failed and only need to retake that part. Retake fees run roughly $30 to $50 for the written portion and $70 to $100 for the skills demonstration. Exhaust your attempts and you have to retake the full training program before testing again. Practice the skills until they’re automatic; it’s far cheaper than repeating the training.
Criminal History and the OIG Exclusion List
A criminal record doesn’t automatically disqualify you, but certain convictions will. Most states maintain lists of disqualifying offenses that include violent crimes, sexual offenses, abuse or neglect of a vulnerable person, theft, and drug trafficking. Some states allow waivers for older or less serious convictions; others impose permanent bars for the most serious offenses. If you have any criminal history, research your state’s disqualifying offense list before paying for training.
There’s also a federal layer. The Office of Inspector General at the U.S. Department of Health and Human Services maintains the List of Excluded Individuals and Entities. If your name is on it, no federal healthcare program payment can be made for services you provide, which effectively locks you out of any facility that accepts Medicare or Medicaid.5Office of Inspector General | U.S. Department of Health and Human Services. Exclusions Employers face civil monetary penalties for hiring excluded individuals and check the list routinely. Reinstatement isn’t automatic; you must apply, and the process can take years.6Office of Inspector General | U.S. Department of Health and Human Services.

Applying for the Registry
After training, assemble your paperwork for the state nurse aide registry: certificate of completion with the program’s state-assigned provider code, background check results, health screening documentation, and the registry application. You’ll provide your full legal name, Social Security number, and residential address. Transcribe dates and provider codes exactly as they appear on your certificate, because mismatches with state records for that program will cause delays.
Applications go through your state’s health department or licensing board, usually via an online portal. Keep copies of everything. Most states complete registry review within two to six weeks after you pass the competency exam.
Keeping Your Certification Active
Caregiver certifications don’t last forever. Most states operate on a two-year renewal cycle. At the federal level, nursing facilities must provide at least 12 hours of in-service training per year, including dementia management and abuse prevention along with topics identified through your performance reviews.7eCFR. 42 CFR Part 483 – Requirements for States and Long Term Care Facilities Many states require more continuing education than that, and some require you to document a minimum number of paid working hours during the renewal period to prove active practice.
Renewal fees are modest, usually nothing to about $50. The real risk is letting the certification lapse. Most states will make you retake the competency exam, and if you’ve been inactive long enough, repeat the full training program. Set a calendar reminder well before your expiration date.
Moving to Another State
If you relocate, you’ll need to get on the nurse aide registry in your new state through a process called reciprocity. It exists in most states but isn’t automatic. You’ll typically submit proof of active certification from your previous state, verify your training hours meet the new state’s minimum, and pass a background check in the new state.
Training hours are the common snag. If you were certified in a 75-hour state and move to a 150-hour state, you may need to complete additional training before the new state accepts you. The new state will also check whether you have any findings of abuse, neglect, or misappropriation of property on any state’s registry. Under federal law, those findings stay on the registry permanently and follow you across state lines.3eCFR. 42 CFR 483.156 – Registry of Nurse Aides
Plan for the transfer to take several weeks. Start the application as soon as you know you’re moving, because you generally cannot work as a nurse aide in the new state until reciprocity is complete and you appear on that state’s registry.
