Personal Care Aide vs. CNA vs. Home Health Aide: What's the Difference?

Published August 19, 2026 · 5 min read

"Caregiver" gets used as a catch-all term, but the roles underneath it are different jobs with different scopes, requirements, and typical entry points. If you're deciding where to start, here's how they compare.

Personal care aide (PCA)

Personal care aides help clients with activities of daily living -- bathing, dressing, grooming, mobility, light meal prep, and household tasks. The work is non-medical: PCAs don't administer medication or perform clinical procedures. This is typically the most accessible entry point into caregiving, with agencies often hiring candidates with no prior experience and providing on-the-job training alongside required ongoing courses.

Companion caregiver

Closely related to a PCA role, companion caregivers focus more on non-medical support and companionship -- conversation, transportation to appointments, light housekeeping, meal prep -- with less hands-on personal care involved. Some agencies treat this as a distinct, even more entry-level role; others fold it into the PCA job description.

Home health aide (HHA)

Home health aides typically work under the supervision of a nurse or clinical team and can have a broader scope than a PCA, sometimes including basic health monitoring (checking vital signs, tracking symptoms) in addition to personal care support. HHAs often work with clients who have more involved medical needs, and the role can carry its own certification requirements depending on the employer and funding source.

Certified Nursing Assistant (CNA)

CNAs have the most formal training and certification requirements of the roles here, typically involving a state-approved training program and competency exam before you can work under the CNA title. CNAs perform more clinical tasks under nursing supervision and are common in both home care and facility settings (nursing homes, hospitals). If you're aiming for a long-term healthcare career, a CNA certification is a well-worn path toward further credentials down the line.

Which one should you start with?

If you're new to caregiving and want to start working as quickly as possible, personal care aide or companion roles are the most common entry points -- many agencies will train you on the job once you're hired. If you already know you want a long-term healthcare career, pursuing a CNA certification earlier can pay off, though it requires more upfront time investment. Either way, completing a foundational course before you apply -- like Caregiver Basics Orientation -- shows agencies you're serious regardless of which specific role you're targeting.
