To obtain a Certified Nursing Assistant (CNA) license in Washington, you must complete a state-approved training program, pass the competency examination, and be listed on the OBRA Nursing Assistant Registry. This guide explains how to apply for certification, verify your status, renew or reinstate your credential, and transfer an active out-of-state certification, based on current regulations from the Washington State Department of Health (DOH) and the Department of Social and Health Services (DSHS). The CNA certification process in Washington is regulated by DOH. The written/oral exam is administered by Credentia, while the skills exam is scheduled directly through approved testing providers. Follow these steps to become certified as a Nursing Assistant-Certified (NAC) in Washington. Complete a DOH-approved Nursing Assistant Training Program with at least 115 total hours: Your training provider must confirm program completion before you can schedule the exam. Other approved eligibility routes (E2–E9) include nursing students, military medics/corpsmen, out-of-state training, and alternative “bridge” programs. These routes require Authorization to Test from DOH before scheduling exams. The skills exam is not scheduled through Credentia. Arrange testing with your training program or a state-approved site listed by the Washington Nursing Commission. You must pass the skills exam before taking the knowledge exam. After passing the skills exam, create an account on the Credentia CNA365® platform to obtain your Candidate ID and schedule the written or oral knowledge exam. Testing is available online with a remote proctor or at a test center. Oral exams must be requested at registration. The National Nurse Aide Assessment Program (NNAAP) in Washington consists of: You must pass both components to qualify for certification. You have up to four attempts at the knowledge exam before retraining is required. There is no overall time limit for these attempts. After passing both exams, submit the Nursing Assistant Certification Application to DOH with the required fee and supporting documents. A fingerprint-based background check may be required. Forms and instructions are available on the DOH website. Once your application is approved, DOH will add your name to the Washington Nurse Aide Registry, confirming your active status. Need help?
