2.5 NAR Versus NAC and the Nursing Home Four-Month Rule

Two Similar Terms, Different Meanings

Washington uses both Nursing Assistant Registered (NAR) and Nursing Assistant Certified (NAC), and they are not the same thing.

• NAR is an entry work status. A person can apply to be a NAR to begin working as a caregiver before completing the full certification process. Crucially, the handbook requires applying as a NAR within three (3) days of employment.
• NAC is the full credential, earned only by passing both the in-person skills test and the online written (or oral) knowledge test, then applying to DOH for certification.

This is the most common search confusion: people looking for "Washington CNA" almost always mean the NAC credential. NAR status lets you start working under supervision; it is not proof you have passed the exam. A NAR who is still in training cannot perform nursing skills on residents until trained on those specific skills.

The Four-Month Rule

The four-month rule is a federal-and-state timing requirement, not a study suggestion. The handbook states plainly: if employed in a nursing facility, you must complete training and OBRA testing through DSHS and apply to become certified through DOH all within four months from the day you start work.

A second sentence narrows who may even use this window: only individuals enrolled in a nursing assistant training program, or waiting to take the exam, qualify to work in a nursing facility under the four-month rule. You cannot be hired off the street with no training plan and rely on the four months.

Because the clock starts on the first day of work, a nursing-facility hire should map exact dates immediately.

Planning Backward From the Window

For a NAR working in a nursing facility, the safest plan is to build backward from the four-month deadline. Washington expects candidates to take the skills test first and to pass it before the program authorizes the written test, so the sequence must fit inside four months:

1. Enroll in (or confirm enrollment in) an approved training program.
2. Apply for the NAC certification to generate the credential number (NAC.NC).
3. Complete training, including the 40-hour clinical component.
4. Pass the skills test (five randomly selected skills).
5. Register through Credentia and pass the 70-question written or oral test.
6. Finish the DOH certification application so your name reaches the OBRA registry.

Do not treat NAR registration as the finish line. Failing to certify within four months can end a facility job, because federal nursing-facility rules bar long-term employment of uncertified aides. If the NAR also has an unusual background (lapsed credential, out-of-state training), a reviewed route may add a DOH application and Authorization to Test on top of the four-month clock - which only makes early planning more important. Track the window using exact dates from employment records rather than memory.

NAR Limits, Scope, and the Registry Connection

NAR status is genuinely useful - it lets a person earn a paycheck while training - but it carries real limits that exam questions love to test:

• No skills on residents until trained on them. A NAR hired into a nursing facility during training cannot perform a nursing skill on a resident until they have been trained on that specific skill. The NAR works under supervision within a narrow, growing scope.
• It is not certification. NAR status is never proof you passed the NAC exam. You still owe both the skills test and the written/oral test, and then a DOH certification application.
• It is time-bound by the four-month rule. In a nursing facility, NAR is a temporary bridge, not a permanent status.

There is also a registry consequence to understand. When you pass both exam parts and become certified, your name is forwarded to the OBRA Nursing Assistant Registry maintained by DSHS, and you become an active certified aide. Until then, a NAR is on a clock. The federal logic behind all of this is OBRA: Medicare- and Medicaid-funded nursing facilities may not employ uncertified aides long-term, which is precisely why the four-month deadline exists and why facilities are required to reimburse their employees' exam fees.

The practical lesson is simple: NAR opens the door to start working, but NAC is the credential that keeps the job. Plan the four-month window the day you are hired, confirm your training enrollment, and never assume registration equals certification.
