CNA Certification Exam and Oklahoma Nurse Aide Registry
The Two-Part Prometric Competency Exam
To earn your Oklahoma nurse aide certification, you must pass a state-approved competency exam administered by Prometric. The exam consists of two separate components that evaluate both your knowledge and your hands-on skills.
The written (or oral) knowledge test includes 60 multiple-choice questions. You have 90 minutes to complete it, and a score of at least 70% is required to pass. If you have difficulty reading English, you can request an oral version at the test site without prior notice. The questions cover the core topics taught in your CNA training program, including infection control, patient rights, safety procedures, and basic nursing skills.
The clinical skills evaluation tests your ability to perform five randomly selected skills from a pool of about 20 possible tasks. You will be given 25 to 30 minutes to demonstrate each skill correctly. A nurse evaluator watches you and marks off critical steps. You must perform all five skills without missing any key steps to pass this portion.
Both parts of the exam must be passed to qualify for registry placement. If you fail one part, you can retake that part only, though retesting policies and fees vary. Check with your test site for specific retake rules.
Registration and What to Bring on Test Day
Registration for the exam takes place at the test site on the day of testing. There is no online pre-registration system. Plan to arrive early with the required documentation and be prepared to pay the exam fee directly at the site. Cash, money order, or a cashier’s check are common payment methods, but confirm acceptable forms with your testing location beforehand.
You must bring valid government-issued photo identification and proof that you successfully completed an approved CNA training program. This typically means your training certificate or a letter from your program director. Without these documents, you will not be permitted to test.
Results are generally available shortly after you finish both exam components. In many cases, you receive unofficial results on the spot, with official notification following within a few business days from the Oklahoma State Department of Health (OSDH) once they process your scores.
Oklahoma Nurse Aide Registry Placement
After passing both parts of the exam, your name is added to the Oklahoma Nurse Aide Registry. This statewide database is maintained by the OSDH and serves as the official list of certified nurse aides eligible for employment in licensed facilities. Employers verify your active status directly through the online registry. Be sure to keep your contact information current with the OSDH after you first register, because renewal notices and important updates go to the address on file.
Renewal Requirements
Certification must be renewed every 24 months. To qualify for renewal, you must have performed paid nursing or nursing-related services during that period. Even a single day of qualifying work is enough to keep your status active. If you go the full two years without working as a CNA, your certification expires and you will need to retrain and retest.
The OSDH sends a renewal reminder by mail. When it arrives, follow the instructions to submit proof of employment and any required fee. Employers routinely check the online registry during the hiring process, so an expired certification can delay or prevent employment.
Understanding Pass Rates and Choosing a Program
Program-level pass rates offer a straightforward way to gauge how well a training program prepares students for the exam. Although the OSDH does not publish a statewide aggregate pass rate, many schools voluntarily share their first-attempt pass rates on their websites or in admissions materials. When comparing programs, ask each one about their recent pass rates. A strong program often maintains a first-attempt pass rate above 80 percent, while a lower rate may suggest gaps in skill practice or test preparation. Checking these figures can help you choose a school where graduates consistently succeed on testing day.
