Washington's Four-Month Rule for NARs: What Happens If You Miss the Deadline

Washington's four-month rule says that a Nursing Assistant-Registered (NAR) hired by a nursing facility must complete an approved training program and pass both parts of the NAC exam within four months of the date of hire. The clock starts on the hire date, not on the first day of class or the day the Department of Health (DOH) issues the NAR. If the deadline passes without certification, the facility can no longer use you as a nursing assistant, and the usual outcomes are reassignment to a non-care role, a pause in employment, or separation until you become a Nursing Assistant-Certified (NA-C). The rule comes from federal nursing home regulations that Washington applies through the NAR credential, so it is not something a facility can waive.

Where the rule comes from and who enforces it

Federal nursing home regulations prohibit a nursing facility from employing anyone as a nurse aide for more than four months unless that person has completed a state-approved training program and passed the state competency exam. States must apply the rule to keep Medicare and Medicaid certification for their facilities. In Washington, the DOH issues the NAR credential that makes pre-certification employment possible, the Washington State Board of Nursing (WABON) sets the training and exam standards, and facility surveyors check compliance during inspections. A facility that keeps an uncertified aide past four months risks a deficiency citation, which is why administrators track the date closely and will act on it.

The rule is about the employer's obligation as much as yours. That is useful to remember when you negotiate: the facility has a strong reason to help you meet the deadline.

Which settings the rule covers

If you are unsure whether your employer is a nursing facility, ask the administrator or check how the facility is licensed. Most buildings with "rehabilitation" or "care center" in the name and long-term residents are nursing facilities.

How the clock runs

The four months are counted from your hire date as a nursing assistant. Three details catch people:

• Orientation counts. If you were hired on March 3 and spent two weeks in orientation, the deadline is still four months from March 3.
• Training start date is irrelevant. Waiting three weeks for a class cohort uses up three weeks of the window.
• Certification means the DOH record shows NA-C. Passing the exam is not enough on its own if the facility's policy requires the credential to be issued; check whether your facility accepts documented exam passes while the DOH application is pending. Some do, some do not.

For how the NAR itself works, including who can apply and what a NAR may do on the floor, see our article on working as a CNA in Washington before certification.

Planning backward from the deadline

A four-month window is 16 to 17 weeks. Lay the milestones out in reverse and the margin is smaller than it looks.

The lesson from the table: a NAR who has not started training by the end of the first month is already behind, and a part-time program that stretches training to 8 or 10 weeks leaves almost no room for a retake. A four-week program is the safest fit for the rule, which is why the CNA Traditional program at Huduma CNA Programs is built that way and administers the skills test on site. Current cohort dates are on the class schedule page.

NARs who already hold an active Washington Home Care Aide credential have an easier calendar. The HCA bridge at Huduma is 40 clock hours over five weekdays or about two and a half weekends, which puts the skills test inside the first month. See the HCA–CNA Bridge program page.

What actually happens when the deadline passes

The facility must stop using you as a nurse aide. What that looks like depends on the employer:

1. Reassignment. Larger facilities often move the employee to a non-care role such as dietary, activities, or environmental services until certification. Pay usually changes with the role.
2. Unpaid leave or schedule removal. Some facilities take the employee off the schedule and reinstate them once the DOH record shows NA-C.
3. Separation. Facilities without an alternative role end employment, sometimes with an offer to rehire on certification.

Whether a new hire date at a different nursing facility starts a fresh four months is a question for the DOH and the facility's compliance staff, not something to assume. Do not rely on switching employers as a strategy; solve the certification instead.

Nothing about missing the deadline affects your ability to finish training or test. The NAR credential itself stays active until its birthday renewal. What you lose is the nursing facility job in the meantime.

The most common reasons NARs miss it

• Late program start. Waiting for a preferred schedule rather than the next available cohort.
• Skills test retakes. Programs must allow at least four attempts, but each retake is scheduled around evaluator availability. Mock testing before the real attempt is the cheapest insurance; our guide to mock skills testing in Washington explains how it works.
• Registering for the knowledge test too early. Credentia registration must wait until the skills pass is recorded. Registering before that creates a mismatch that takes time to fix.
• Incomplete DOH application. A missing fee, an unanswered attestation, or a training completion report the program has not filed. Check Provider Credential Search weekly once you apply.
• Background check surprises. An undisclosed conviction found in the name-based statewide check triggers a review that can run past the deadline. Disclose everything up front.

How to protect yourself from day one

Ask the facility for the exact deadline date in writing when you are hired, and put the milestones from the table above on a calendar. Confirm whether the employer reimburses tuition or the $155 in exam fees, and whether it will adjust your shifts around class. Enroll in the next available four-week cohort rather than a later one that fits better, and complete the program's background check immediately so clinical placement is not delayed. Finally, keep copies of every result: the skills pass, the Credentia score report, and the DOH application confirmation. If the facility questions your status at week 15, documents settle it faster than phone calls.

Frequently asked questions

Does the four-month rule apply if I work in a hospital? Not under the federal nursing facility rule, unless you work in a hospital-based skilled nursing unit. Hospitals set their own deadline in policy, and many mirror the four-month standard anyway.

Does the clock pause if I go on leave? The federal rule counts calendar time from hire. Ask your administrator how the facility documents a leave, but plan as if the clock keeps running.

Can the facility extend the deadline if I have a skills test scheduled? No. The facility cannot waive a federal requirement. Some facilities accept a documented exam pass while the DOH application is pending, which is the closest thing to flexibility.

What if I fail the skills test at week 14? You still have at least three more attempts under Washington rules, but the four-month window will almost certainly close before you can retake, test with Credentia, and get the DOH record updated. Expect reassignment until you are certified.

Does the four-month rule apply to out-of-state CNAs waiting for endorsement? If a nursing facility hires them as a NAR, yes. Endorsement usually completes well inside four months, and our article on CNA reciprocity in Washington explains the timing.

The rule rewards speed at the front of the window. Start training in the first weeks after hire, test as soon as your program allows, and the deadline becomes a formality. For the difference between the two credentials at the center of this rule, read NAR vs NAC in Washington.
