A DSP (direct support professional) supports people with intellectual and developmental disabilities to live, work and take part in their communities. A CNA (certified nursing assistant) gives basic hands-on care under nurse supervision, most often in nursing homes and hospitals. The biggest regulatory difference is training. Federal rules require nursing assistants in Medicare- and Medicaid-certified nursing homes to complete at least 75 hours of state-approved training and pass a competency evaluation (42 CFR 483.152). No federal hour minimum exists for DSPs, so states set DSP standards.
Both jobs count as direct care work in federal Medicaid rules, which list licensed or certified nursing assistants and direct support professionals as separate kinds of direct care worker (42 CFR 441.302(k)). Our glossary entry on DSP vs CNA gives the short version. This page covers the rules behind it.
DSP vs. CNA at a glance
| DSP (direct support professional) | CNA (certified nursing assistant) | |
|---|---|---|
| Main purpose | Support a person's independence, community life and personal goals | Basic nursing care and help with daily living under nurse supervision |
| Typical settings | Group homes, supported living, day and job programs, family homes, ICFs/IID | Nursing homes (36% of jobs) and hospitals (32%), per BLS |
| Who directs the work | The person's person-centered service plan | A nurse's direction and the facility's care plan |
| Federal training minimum | None in HCBS. States set standards, and ICFs/IID must train staff in each resident's needs | 75 clock hours, including 16 hours of supervised practical training, plus a competency evaluation (nursing homes) |
| Ongoing training | Set by the state or the facility | At least 12 hours of in-service training a year (nursing homes) |
| Registry | No federal registry requirement | Each state must keep a nurse aide registry |
| Federal job code | None (S. 3211 would ask OMB to consider one) | Nursing assistants, SOC 31-1131 |
| Median pay (BLS, May 2025) | No DSP figure. Home health and personal care aides earned $35,800 a year | Nursing assistants earned $42,260 a year |
| Main federal rules | State provider standards under Medicaid waivers (42 CFR 441.302) | Nursing home requirements (42 CFR part 483, subparts B and D) |
What a CNA is, by regulation
The federal rules for nursing homes certified by Medicare or Medicaid set a national floor for nurse aides. A state-approved nurse aide training and competency evaluation program must include:
- At least 75 clock hours of training (42 CFR 483.152(a)).
- At least 16 hours of supervised practical training, with 16 hours of instruction in core topics before the trainee has any direct contact with residents.
- Training led by, or under the general supervision of, a registered nurse with at least two years of nursing experience, at least one of them in long-term care.
A nursing home may not use someone as a nurse aide for more than four months, full time, unless that person has completed training and passed a competency evaluation (42 CFR 483.35(d)). Nursing homes must provide at least 12 hours of in-service training a year (42 CFR 483.95(g)). Each state must also keep a registry of nurse aides (42 CFR 483.156). The Bureau of Labor Statistics notes that nursing assistants must be on their state's registry to work in a nursing home. The official title varies by state, and "CNA" is common.
Aides who are employed by a nursing home, or have a job offer from one, when they start a state-approved program can't be charged for it (42 CFR 483.152(c)). States may add hours on top of the federal minimum.
What a DSP is, by regulation
DSP rules are looser at the federal level and more varied across states. Medicaid home and community-based services run mainly through waivers, and each state must assure CMS that it has adequate standards for every type of provider (42 CFR 441.302(a)). States set DSP training hours, topics and competency checks.
In an ICF/IID, federal rules require direct care staff to receive initial and ongoing training focused on residents' needs, and staff must be able to demonstrate the skills they use (42 CFR 483.430(e)). The rules set no hour count.
The job itself is also different. A Senate bill, S. 3211, describes DSP work as enhancing community inclusion, coaching people to communicate and reach their goals, helping with daily living, and supporting people at home, work, school or in the community. That work follows each person's written person-centered service plan, which federal waiver rules require and review at least every 12 months (42 CFR 441.301).
How the jobs overlap
Both roles may help with bathing, eating, toileting and moving around. Both count as direct care workers under 42 CFR 441.302(k). Both are part of a workforce that states say is short-staffed. In a KFF survey of state Medicaid programs published in January 2026, 48 states reported DSP shortages and 39 reported CNA shortages.
The differences come down to purpose and oversight:
- Clinical vs. community focus: CNAs work within a nursing care plan under nurse supervision. DSPs work toward goals the person sets, including jobs, relationships and community life.
- Federal floor vs. state standards: A CNA has a defined federal training floor and a state registry listing. A DSP's requirements depend on the state and the service.
- Setting: Most CNA jobs are in nursing homes and hospitals. Of the 729,000 people with I/DD who used Medicaid long-term care in 2021, about 700,000 received it at home or in the community, KFF reports, so most DSP work happens there.
How it varies by state
For CNAs, states run the training approval, the competency evaluation and the registry, and many add hours above the federal 75. For DSPs, states set the entire standard through their waiver applications and provider rules. Whether a CNA certificate counts toward a state's DSP requirements is up to that state's rules. Check your state's developmental disabilities agency and waiver documents.
Why it matters for providers and DSPs
- Hiring: A CNA applicant brings clinical skills but may be new to habilitation, community inclusion and person-centered practice. Plan orientation around that gap.
- Pay competition: BLS figures show nursing assistants with a higher median annual wage ($42,260) than home health and personal care aides ($35,800) as of May 2025. Agencies competing with nursing homes and hospitals for the same workers feel that gap.
- Job descriptions: Using the right title matters. Our glossary notes that a listing that says only "direct care" can draw applicants who don't expect community-based support work.
- Policy: Wage rules written for "direct care workers" may cover both roles, so check the definition in each rule.
