HHA vs CNA: What's the Difference?
Comparing Home Health Aide (HHA) and Certified Nursing Assistant (CNA) certifications — training requirements, scope of practice, pay, and which path is right for you.
If you're entering the healthcare field, you've likely come across both HHA and CNA certifications. They're similar in many ways — but the differences matter when it comes to where you work, what you do, and how much you earn.
What Is an HHA?
A Home Health Aide (HHA) is a certified care worker who assists clients with activities of daily living (ADLs) in their homes or community settings. HHAs work under the supervision of a registered nurse or therapist and provide personal care, light housekeeping, and companionship.
Typical HHA duties:
- Bathing, grooming, and dressing
- Meal preparation and feeding assistance
- Vital signs monitoring
- Mobility assistance and transfers
- Light housekeeping and errands
- Companionship and emotional support
What Is a CNA?
A Certified Nursing Assistant (CNA) performs many of the same tasks as an HHA but works primarily in clinical settings — nursing homes, hospitals, and long-term care facilities. CNAs typically have more clinical training and a broader scope of practice.
Typical CNA duties:
- All HHA duties, plus:
- Catheter care
- Wound observation and reporting
- More advanced vital signs (in some states)
- Direct collaboration with nursing staff in clinical settings
Training Requirements
| HHA | CNA |
|---|
|--|-----|-----|
| **Training hours** | 75–120 hours (varies by state) | 75–175 hours (varies by state) |
|---|---|---|
| Clinical hours | 16+ hours | 16–100+ hours |
| Exam required | Written + skills demonstration | Written + skills demonstration |
| Time to certify | 4–8 weeks | 4–12 weeks |
| Cost | $200–$1,500 | $500–$3,000 |
Scope of Practice: Key Differences
The biggest practical difference is where and what you can practice:
- HHAs are primarily authorized to work in home settings. They focus on personal care and cannot perform most clinical procedures.
- CNAs can work in nursing homes, hospitals, rehab centers, and more. They have a broader clinical scope.
In many states, an HHA certification also allows you to work in assisted living facilities.
Pay Comparison
According to the Bureau of Labor Statistics:
- HHA median hourly wage: ~$15.00/hour
- CNA median hourly wage: ~$16.50/hour
The pay gap is modest. HHAs who specialize in home care for high-need clients can earn comparable wages to CNAs, especially with overtime and live-in arrangements.
Which Should You Choose?
Choose HHA if:
- You want to work one-on-one with clients in their homes
- You prefer a shorter, lower-cost training program
- You want to start working quickly
- You value flexibility and independence
Choose CNA if:
- You want to work in a hospital or nursing home
- You're considering advancing to LPN or RN eventually (CNA is a common stepping stone)
- You want a broader clinical skillset
- You're comfortable in a faster-paced environment
Can You Get Both?
Yes — and many care workers do. In most states, completing an HHA program gives you credit toward CNA certification. If you start as an HHA and want to advance, you often only need to complete the additional CNA training hours rather than starting from scratch.
The Bottom Line
Both HHA and CNA are excellent entry points into healthcare. HHA is faster and cheaper to certify, and is ideal if you want to work in home care. CNA opens more doors in clinical settings and is a stronger foundation for career advancement.
Either way — start with your state's requirements, because training hours and scope of practice vary significantly.
