RN, LVN, CNA, home health aide, caregiver: who can legally do what in California?

What is the difference between an RN, an LVN, a CNA, a home health aide and a caregiver in California?

That distinction is easy to state and surprisingly hard to see from the outside. Everyone in this field is competent at something. A home care aide who has been with the same family for six years knows things about that person no nurse will learn in a first visit, and there is nothing patronizing about saying that the aide is the right professional for most of what that family needs. What families struggle with is the moment the situation crosses a line, when a wound starts looking different, or a parent becomes confused overnight, or a new medication arrives from the hospital with instructions nobody read out loud. In that moment the credential stops being paperwork and starts determining what can lawfully happen next.

California is also genuinely different from most other states here, which is why generic national explainers get families into trouble. Two separate state departments license two separate kinds of organization, with two separate meanings of the word "home." The training hours are higher than the federal floor in most categories. And the definition of nonmedical home care services is written into statute with a specificity that few states match, right down to a clause about medication that answers a question families ask constantly. What follows works through each credential in turn, then puts them side by side.

What can a Registered Nurse legally do in California?

An RN holds the widest scope of any of these credentials, and the reason is written into the statute in a way that is worth reading closely. Business and Professions Code section 2725 defines the practice of nursing to include four things: direct and indirect patient care ensuring the safety, comfort, personal hygiene and protection of patients along with disease prevention and restorative measures; the administration of medications and therapeutic agents necessary to implement a treatment or rehabilitative regimen ordered by a physician, dentist, podiatrist or clinical psychologist; the performance of skin tests, immunization techniques and the withdrawal of blood from veins and arteries; and the observation of signs and symptoms, reactions to treatment, general behavior or general physical condition together with the determination of whether those exhibit abnormal characteristics and the implementation of appropriate reporting, referral, standardized procedures or emergency procedures.

That fourth item is the one that changes what happens in a house. It is nursing assessment, and it is an independent judgment. An RN may look at a leg that is warmer and more swollen than it was yesterday, decide that this is abnormal, and act on that decision, whether that means escalating to the physician, initiating a standardized procedure, or calling for emergency care. Nobody else in this list holds that authority in their own right. The Board of Registered Nursing, part of the California Department of Consumer Affairs, regulates the license, and section 2732 makes it unlawful to practice nursing without an active license and protects the title, so only a licensee may call themselves a registered nurse or use the letters R.N.

What an RN cannot do is diagnose or prescribe as a physician does. Medication administration under section 2725 is administration of a regimen ordered by an authorized prescriber, not the writing of that order. Nurse practitioners hold additional authority beyond the standard RN license, which is a separate topic. For a family arranging care at home, the practical summary is that an RN can carry out physician-ordered treatment and can independently evaluate and escalate a changing situation, and those two capabilities together are usually what people mean when they say they want a nurse rather than a caregiver.

What can a Licensed Vocational Nurse legally do in California?

An LVN is a licensed nurse, regulated by the Board of Vocational Nursing and Psychiatric Technicians, and the license is real. LVNs give medications, perform treatments, monitor patients and carry a great deal of the clinical work in skilled nursing facilities and home health. Most other states call the same role a licensed practical nurse, or LPN.

The statutory difference from an RN sits in a single phrase. Business and Professions Code section 2859 defines the practice of vocational nursing as the performance of services requiring technical and manual skills acquired through an approved school of vocational nursing or its equivalent, "practiced under the direction of" a licensed physician and surgeon, a registered nurse as defined in section 2725, or a naturopathic doctor. The direction requirement is not a workplace policy layered on top of the license. It is inside the definition of the profession itself. An LVN is, by design, not an independent practitioner.

Specific procedures carry their own conditions. Under section 2860.5, an LVN when directed by a physician may administer medications by hypodermic injection and may withdraw blood, provided the nurse has been instructed and has demonstrated competence. Starting and superimposing intravenous fluids requires more still: a board-approved course of instruction or demonstrated competence to the board's satisfaction, and performance within an organized health care system in accordance with that system's written standardized procedures. In practice this is why LVN job listings so often specify IV certification, and why the answer to "can an LVN start an IV" is genuinely "it depends on this particular LVN's certifications and setting."

None of this makes an LVN a lesser clinician. It makes them a differently structured one. When a family hires an LVN privately, the question worth asking is not whether the person is skilled, but who is providing the statutory direction and how that works day to day. A confident, specific answer is a good sign. A vague one is worth pursuing.

What can a Certified Nursing Assistant legally do in California?

A CNA holds a state certificate, not a nursing license, and the distinction is not pedantic: certification means the person completed an approved training program and passed a competency evaluation, while licensure means the person holds independent legal authority to practice a profession. Health and Safety Code section 1337.1 sets the precertification training program at a minimum of 60 classroom hours covering basic nursing skills, patient safety and rights, the social and psychological problems of patients, and resident abuse prevention, recognition and reporting, plus at least 100 hours of supervised on-the-job clinical practice. That is 160 hours in total, well above the 75-hour federal floor, and it includes mandated minimums for dementia content and abuse reporting.

The curriculum is oriented toward skilled nursing and intermediate care facilities, which is where the certificate originated and where most CNAs work. A CNA assists with bathing, dressing, toileting, transfers, mobility, feeding and hygiene, takes and records vital signs, observes and reports changes, and does so under the supervision of a licensed nurse. What a CNA does not hold is the authority to assess. Observing that a patient seems different and reporting it up is within the role. Deciding what that difference means clinically and acting on that decision is nursing.

California draws that line explicitly in one setting. Business and Professions Code section 2725.3 provides that a licensed health facility, meaning a general acute care hospital, acute psychiatric hospital or skilled nursing facility, may not allow unlicensed personnel to perform functions requiring a substantial amount of scientific knowledge and technical skills, and it lists them: administration of medication, venipuncture or intravenous therapy, parenteral or tube feedings, invasive procedures including inserting nasogastric tubes, inserting catheters or tracheal suctioning, assessment of patient condition, educating patients and families about their health care problems including postdischarge care, and moderate complexity laboratory tests. That statute governs facilities rather than private homes, so it is not a home care rule. It is, however, the clearest published statement of where the California legislature believes the line between licensed and unlicensed work sits, and it is a reasonable list for a family to keep in mind.

What is a Certified Home Health Aide, and how is it different from a CNA?

A certified home health aide, usually abbreviated CHHA, is the home-based counterpart to the CNA. Both are certified by the same body, the Aide and Technician Certification Section within the California Department of Public Health's Licensing and Certification Program. The difference is the setting the credential was designed for and the legal structure the aide works inside.

Health and Safety Code section 1727 defines a home health aide as an aide who has successfully completed a state-approved training program, is employed by a home health agency or hospice program, and provides personal care services in the patient's home. It then defines home health aide services as personal care services provided under a physician's plan of treatment. Two things follow from that definition. A CHHA's work in this capacity sits inside a licensed organization, and it sits under a physician's written plan. This is not a credential designed for a person a family hires directly off a website.

Training requirements have two layers, which is a common source of confusion. Health and Safety Code section 1736.1 sets the statutory floor at a training program of a minimum of 75 hours, or an equivalent department-approved competency evaluation program, along with a criminal record clearance. The implementing regulation goes further: Title 22 of the California Code of Regulations, section 74747, requires the basic training program for certification to be a minimum of 120 hours, with no more than 75 hours of classroom lecture and a minimum of 20 hours of clinical experience, broken down into 15 hours of personal services, 2 hours of cleaning and care tasks and 3 hours of nutrition. People who already hold a CNA certificate can typically bridge across on a shorter program rather than repeating the full curriculum.

For a family, the useful takeaway is this: if someone tells you they are sending a "home health aide," the phrase carries a specific legal meaning in California that implies a home health agency, a physician's plan of treatment, and usually an insurance or Medicare pathway. If none of those things are present, the person being described is probably a home care aide, which is a different credential entirely.

What is a registered Home Care Aide in California?

This is the credential most privately hired caregivers in California actually hold, and it is the one most often misunderstood. It comes from the Home Care Services Consumer Protection Act, which took effect in January 2016 and is administered by the Home Care Services Branch of the California Department of Social Services. The Act does two things: it requires home care organizations to be licensed, and it creates a public online registry of home care aides who have cleared a criminal background check.

Registration is not a clinical credential. Under Health and Safety Code section 1796.19, the department reviews an applicant's ability to comply with the chapter, evidence of reputable and responsible character including a review of criminal offender record information, and any prior revocation or disciplinary action related to the care of individuals. Fingerprints go to the Department of Justice through Live Scan. What comes out the other end is a Personnel Identification Number and a listing on the registry. That is a meaningful consumer protection and I would not want a family to skip checking it. It is simply answering a question about trustworthiness, not about clinical skill.

Training is thinner than most families assume, and it applies unevenly. Health and Safety Code section 1796.44 requires an affiliated home care aide, meaning one employed by a licensed home care organization, to complete a minimum of five hours of entry-level training before being present with a client: two hours of orientation covering the role and terms of employment, and three hours of safety training covering basic safety precautions, emergency procedures and infection control. After that, a minimum of five hours of annual training covering client rights and safety, daily living needs, recognizing and reporting abuse and neglect, personal hygiene assistance and safe transportation where applicable. All of it may be completed online.

The statute also distinguishes two kinds of aide. An affiliated home care aide is employed by a licensed home care organization and appears on the registry. An independent home care aide is not employed by an organization, appears on the registry, and provides services through a direct agreement with the client. If you hire someone privately and they are on the registry, that is the category they fall into.

What a registered home care aide may do is spelled out with unusual precision. Health and Safety Code section 1796.12 defines home care services as "nonmedical services and assistance provided by a registered home care aide to a client who, because of advanced age or physical or mental disability, cannot perform these services," and then lists them: bathing, dressing, feeding, exercising, personal hygiene and grooming, transferring, ambulating, positioning, toileting and incontinence care, assisting with medication that the client self-administers, housekeeping, meal planning and preparation, laundry, transportation, correspondence, making telephone calls, shopping for personal care items or groceries, and companionship.

The first word of that definition is the whole argument. Nonmedical. Everything downstream of it follows.

What can an unlicensed caregiver or companion legally do?

A privately hired caregiver who holds no license, no certificate and no registration is not doing anything unlawful by existing. California does not require a person to hold a credential in order to help a neighbor with groceries, drive a parent to an appointment, cook, clean, keep company or provide the ordinary hands-on help that families have always provided for one another. Section 1796.14 of the Health and Safety Code also lists categories that fall outside the Home Care Services Consumer Protection Act altogether, including people providing services through licensed home health agencies, hospices, health facilities and clinics, and people working through the In-Home Supportive Services program.

The outer boundary is section 2732: no person may engage in the practice of nursing, as defined in section 2725, without an active license. That is the line an unlicensed caregiver cannot cross, and it is worth understanding that it is drawn around the activity, not around the job title. A very experienced caregiver who has done a task a hundred times for a previous family is not thereby authorized to do it for yours.

There is a second, quieter consideration that has nothing to do with scope of practice. An unregistered caregiver has not been background checked by the state, has not been vetted by anyone but you, and if you are paying them directly you are likely their employer for tax, workers' compensation and wage-and-hour purposes. Those are not clinical risks, but they are the ones that most often surprise families, and they are worth taking advice on separately.

Which credential can legally do which task in California?

This is the table families actually want. It reflects each credential's general statutory scope in a private home setting, and it is a starting point for a conversation rather than a substitute for one, because individual certifications, employer policy and the presence or absence of a physician's order all shift the picture.

Sources: Business and Professions Code sections 2725, 2732, 2859 and 2860.5; Health and Safety Code sections 1337.1, 1727, 1736.1 and 1796.12; California Code of Regulations title 22 section 74747. The row on unlicensed caregivers reflects that no California credential authorizes an unlicensed person to perform nursing, per Business and Professions Code section 2732.

Which specific tasks require a licensed nurse in California?

Families usually arrive at this page with one particular task in mind, so it is worth answering the common ones directly rather than in the abstract.

Medication. The dividing line is between assistance and administration, and California puts it in writing. Section 1796.12 permits a registered home care aide to assist "with medication that the client self-administers," and then adds a sentence that settles most arguments: this "shall not authorize a registered home care aide to assist with medication that the client self-administers that would otherwise require administration or oversight by a licensed health care professional." An aide may bring the bottle, open it, read the label aloud and remind someone it is time. Drawing up a dose, giving an injection, administering anything through a feeding tube, or exercising judgment about whether a dose should be held tonight is administration, and section 2725 puts administration inside the practice of nursing.

Wound care. Wound care is not among the home care services listed in section 1796.12, and it is not personal care. Assessing a wound, measuring it, packing it, judging whether it is infected and changing the dressing are nursing treatment. Section 1727 defines skilled nursing services as services provided by a registered nurse or a licensed vocational nurse, which is the plainest available statement of where this work sits in California law.

Injections, IV therapy and blood draws. Section 2725 places skin tests, immunization techniques and the withdrawal of blood from veins and arteries inside the RN scope. For an LVN, section 2860.5 permits hypodermic injections and blood withdrawal when directed by a physician and after instruction and demonstrated competence, and permits starting and superimposing IV fluids only with board-approved training and within an organized health care system operating under written standardized procedures. Nothing in either statute extends any of this to a certified aide or a registered home care aide.

Catheters, drains and feeding tubes. These are invasive procedures. Section 2725.3's facility list names inserting catheters, inserting nasogastric tubes, tracheal suctioning and parenteral or tube feedings as functions unlicensed personnel may not perform. In a home the statute does not directly apply, but the underlying reasoning does, and there is no provision anywhere in California law that authorizes an aide to perform them.

Assessment. This is the quiet one, and it is the one that matters most. Section 2725 gives the RN authority to observe signs and symptoms, determine whether they exhibit abnormal characteristics, and implement appropriate reporting, referral, standardized procedures or emergency procedures. Everyone else in the home can and should observe and report. Only a nurse can decide what the observation means and act on the decision. When a family says a night went badly because nobody knew what to do, this is nearly always the gap they are describing.

What is the difference between a Home Care Organization licence and a Home Health Agency licence?

Two departments, two statutes, two very different permissions. This is the single most useful distinction on this page for a family comparing providers, and almost nobody explains it.

A Home Care Organization licence comes from the California Department of Social Services under the Home Care Services Consumer Protection Act. Section 1796.12 defines a home care organization as an entity "that arranges for home care services by an affiliated home care aide to a client," and home care services, as we have seen, are nonmedical by statutory definition. An HCO may employ and dispatch registered home care aides. It may not, on the strength of that licence, put nurses into homes to deliver nursing.

A Home Health Agency licence comes from the California Department of Public Health. Health and Safety Code section 1725 states that all organizations providing skilled nursing services to patients in the home must obtain a home health agency licence, and section 1726 makes it unlawful for an organization to provide, or arrange for the provision of, skilled nursing services in the home without one. Section 1727 then defines skilled nursing services as services provided by a registered nurse or a licensed vocational nurse. Put those three together and the test becomes concrete: an organization that provides or arranges nursing in homes is operating in home health territory and needs a CDPH licence to do it. Section 1726 does carve out an employment agency or a licensed nurses' registry performing its functions under Title 2.91 of the Civil Code, unless that entity is performing the functions of a home health agency.

Why this matters when you are choosing: the two licences tell you what an organization is legally structured to deliver. If a provider is describing nursing tasks, it is entirely reasonable to ask which licence they hold and to look it up. Home care organizations appear in the Department of Social Services facility search. Home health agencies appear in Cal Health Find, the Department of Public Health's facility database. Both are free.

What is the Home Care Aide Registry, and how do I look someone up?

The Home Care Aide Registry is a public website maintained by the Department of Social Services listing registered home care aides and applicants. Section 1796.12 specifies what it contains: the individual's name, registration number, registration status, registration expiration date and, where applicable, the home care organization they are affiliated with. Anyone can search it, free, at ccld.dss.ca.gov/hcsregistry/registrysearch.aspx.

The one practical catch is that the search requires three fields, not two: first name, last name, and the aide's Personnel Identification Number, commonly written PER ID or HCA ID. You cannot browse by name alone. So the step that actually matters happens before you open the website: ask the aide, or the agency sending them, for the PER ID. A registered aide will have it and will hand it over without fuss. Hesitation at that request is itself informative.

Read the result carefully rather than glancing at it. Confirm the status is current rather than pending, expired or otherwise flagged. Check the expiration date, because registration runs in two-year cycles and lapses happen. And look at whether an affiliated organization is listed, because if someone has told you they work independently and the registry shows an employer, or the reverse, that is a discrepancy worth asking about directly.

How do I verify any provider's licence or registration myself?

Every credential on this page is publicly verifiable, free, in a couple of minutes, and no provider should be anything but comfortable with you doing it. Here is where each one lives.

A note on how to use these well. A clean licence lookup tells you that a person holds the credential they claim and has no public discipline. It does not tell you they are good at their job, that they are a fit for your parent, or that they are insured and bonded. Those are separate questions, and references and a trial period answer them better than any database. Verification is the floor, not the ceiling.

Which credential does your situation actually need?

Work backwards from the tasks rather than forwards from a job title. Write down what actually has to happen in a week, in specific terms: two showers, meals, someone at the house overnight, transport to a Thursday appointment, a dressing change every other day, insulin twice daily, and someone who will notice if the confusion is getting worse. Then run that list against the table above. Most families discover that the great majority of the hours are personal care and companionship, which an aide is trained and permitted to provide, and that a small number of tasks are clinical.

Once you can see it that way, the choice usually stops being either-or. A common and sensible pattern is aide hours for the bulk of the week with a licensed nurse involved for the clinical tasks and for oversight of the plan. What tends to go wrong is not choosing the wrong credential, it is never doing the exercise at all: hiring a caregiver because a friend recommended one, and then, three weeks later, quietly asking that caregiver to do something the law does not permit because there is nobody else there at ten o'clock at night.

If the situation is genuinely unclear, that ambiguity is itself worth a conversation with a nurse before you commit to anyone. It is a short conversation, and it is a great deal cheaper than a mismatch.
