If you’re considering a career in caregiving, you’ve likely encountered three prominent credentials: CNA, HHA, and PCA. While all three involve supporting individuals with personal care needs, they differ significantly in terms of training requirements, work settings, responsibilities, and earning potential.
This guide breaks down each credential clearly — so you can make an informed decision about which path aligns with your goals, your timeline, and your budget.
The Three Core Caregiving Credentials at a Glance
CNA (Certified Nursing Assistant): Works in licensed facilities (nursing homes, hospitals); requires passing a state exam; highest earning potential among the three.
HHA (Home Health Aide): Works in clients’ homes through licensed agencies; requires completing an approved training program; ideal for hands-on in-home care.
PCA (Personal Care Assistant): Provides non-medical personal care in private or family settings; most flexible path; great entry point for career changers.
Certified Nursing Assistant (CNA) — In Depth
The CNA credential is the most formal of the three and requires the most preparation. CNAs work under the supervision of Registered Nurses (RNs) or Licensed Practical Nurses (LPNs) in licensed care facilities including:
- Nursing homes and long-term care facilities
- Hospitals (particularly on medical-surgical and geriatric units)
- Rehabilitation centers
- Assisted living communities
CNA training typically requires 150+ hours of combined coursework and clinical practice, followed by a state-administered competency exam with written and skills components. Once licensed, CNAs have some of the broadest employment options in the caregiving space and are often the first point of contact for patients in facility settings.
NCOOA’s CNA Online Exam Prep Course is a 150+ hour program designed to prepare you for the state exam. It covers infection control, CPR, vital signs, hygiene, mobility, and 21 essential nursing procedures — everything you need to walk into your state exam with confidence.
Home Health Aide (HHA) — In Depth
The HHA credential sits between PCA and CNA in terms of complexity. HHAs work primarily in clients’ homes through licensed home care agencies and must complete state-approved training (typically 75+ hours) to qualify for agency employment.
HHAs provide skilled personal care that goes beyond simple companionship, including:
- Monitoring and recording vital signs
- Assisting with medically necessary exercises
- Catheter and wound care under nursing supervision
- Complex hygiene procedures for clients with medical conditions
HHA positions are especially popular among caregivers who prefer one-on-one client relationships and the flexibility of home-based work over facility environments.
NCOOA’s Home Health Aide Online Course is the platform’s most popular course, covering 75+ hours of self-paced training that includes ADLs, vital signs, infection control, mobility support, and emotional care. The course is structured to prepare you for home care agency competency evaluations.
Personal Care Assistant (PCA) — In Depth
The PCA credential is the most accessible entry point into professional caregiving. PCAs typically work in private home settings — either hired directly by families or through personal care agencies — and focus on non-medical support including:
- Hygiene and grooming assistance
- Meal preparation and nutritional support
- Companionship and emotional wellbeing
- Light housekeeping and errand support
- Medication reminders (not administration)
PCA training requirements vary widely by state. While some states have formal requirements, others allow employers to set their own standards. Even where training isn’t mandated, completing a formal program dramatically improves both employability and care quality.

Which Path Should You Choose?
Choose CNA if: You want to work in hospitals or nursing homes, can invest 6–12 months in training, and are prepared to pass a state exam. This path offers the most formal career trajectory in caregiving.
Choose HHA if: You prefer in-home work with agency support, want structured training without a state exam requirement, and value building long-term relationships with individual clients.
Choose PCA if: You want to enter the workforce quickly, prefer independent or private family settings, or are caring for a family member and want foundational training fast.
The good news? All three paths are available through National Caregiver Organization (NCOOA) — entirely online, entirely self-paced, starting from $64.99.
