The national exams: CORE of Knowledge and Line of Service
Quick answer
How many national exams does a nursing home administrator take?
Two. Licensure sits on the national exams administered by the National Association of Long Term Care Administrator Boards (NAB): the CORE of Knowledge exam, shared by all long-term-care administrators, plus one Line-of-Service exam for your setting. For a nursing home you take the CORE plus the Nursing Home Administrator line. Some states add a separate state law exam on top.
The two national exams
A nursing home administrator credential is built on two national exams, not one. The first, the CORE of Knowledge exam, tests the knowledge every long-term-care administrator shares: resident care and quality, the physical environment and safety, human resources, finance, leadership and governance, and the regulatory framework. The second, a Line-of-Service exam, tests the knowledge specific to the setting you want to run. For a nursing home, that is the Nursing Home Administrator (NHA) line. Nearly every state requires both, and both are national exams, so they do not change when you move between states.
Why split it in two? Long-term care is not one setting. Rather than build a separate, mostly redundant exam for each, the shared foundation is examined once in the CORE, and the specialty is examined separately. That is also why adding a second credential later can be lighter: your CORE may already be behind you. The CORE vs Line-of-Service guide walks through the design in full.
The three Lines of Service
On top of the CORE you take one Line-of-Service exam, matched to the setting you intend to administer:
| Line of Service | Setting it licenses you for |
|---|---|
| Nursing Home Administrator NHA | The Line of Service for a nursing-home (skilled nursing facility) administrator license. |
| Residential Care / Assisted Living RCAL | The Line of Service for a residential-care or assisted-living administrator license, where a state licenses that role. |
| Home and Community-Based Services HCBS | The Line of Service for home and community-based services administration, where a state licenses that role. |
You take only the line for the credential you are pursuing. If you later add an assisted living credential, you would add the Residential Care or Assisted Living line, and depending on the state your CORE may already count. See the dual-credential guide.
When a state exam sits on top
The two national exams are not always the whole picture. Some states add a separate state law or jurisprudence exam, testing that state's own licensing statutes and administrative rules. This is not a Line-of-Service exam; it is an additional, state-specific requirement.
- Florida requires its own Nursing Home Administrator Laws and Rules examination in addition to the national NAB exam.
- Virginia requires only the national NAB exam, with no separate state exam.
Whether a state exam applies to you is a per-state fact. The requirements wizard flags it for your state, and each state page records it with its source and date.
How to prepare for a two-exam structure
Because the CORE is broad and shared, it rewards steady, wide preparation across every functional area of administration. The Line-of-Service exam rewards setting-specific depth. Plan your study to reflect that split rather than treating the two as one block. For where the exams sit in the whole licensure sequence, see how to become a licensed nursing home administrator.
