About this exam

The Ohio nurse aide credential - still widely called the STNA, for State Tested Nurse Aide - is the entry-level license to work in nursing homes, assisted living, hospitals, and home care in Ohio. It is administered through a state-approved competency evaluation process: a candidate completes a state-approved training program, then passes a written or oral knowledge test and a hands-on skills demonstration. The written test samples the full scope of aide practice: resident rights and the aide's role, communication, safety and emergencies, infection control and standard precautions, personal care and hygiene, basic nursing skills and vital signs, nutrition and hydration, elimination, restorative care and body mechanics, and mental health and behavioral support. Skills testing asks you to perform selected procedures exactly as taught, in order, with safe technique and correct hand hygiene. Preparation works best in layers: master the skills checklists first, because they are the most objective part of the exam, then drill the knowledge domains in proportion to their weight, and finish with practice questions under timed conditions. Always confirm current scheduling, scoring, fees, and retake rules directly with the state-approved testing vendor, which publishes the figures in effect for your testing cycle.

What you'll study

Common questions

About Ohio CNA (formerly STNA) preparation

What exactly is the difference between an STNA and a CNA in Ohio?

They refer to the same job. Ohio historically used "State Tested Nurse Aide," and the credential is now commonly listed as CNA. Employers, job postings, and training programs use the terms interchangeably, so do not worry if your application says one and your certificate says the other. Both mean you completed approved training and passed the competency evaluation.

How is the exam structured on test day?

You take a knowledge test in multiple choice form - an oral version is available for candidates who qualify - plus a separate hands-on skills demonstration where you perform assigned procedures on a person or simulated setting while an evaluator observes. The two parts are typically scheduled in one session. The vendor's candidate handbook lists the exact procedures and scoring rules currently in effect.

How hard is the skills portion, really?

It is not intellectually hard, but it is unforgiving of shortcuts. Most failures come from skipped hand hygiene, missed steps in a sequence, omitting a safety check such as locking a wheelchair or raising a side rail, or forgetting to tell the resident what you are doing. Practice each procedure out loud, in order, on a live practice partner until the steps are automatic.

What are the most common reasons candidates fail the knowledge test?

Reading too fast on scenario questions is the biggest one. Items ask what you should do first or what is safest, not what is technically possible, so candidates pick a reasonable answer that ignores the priority. The second common cause is weak infection control and safety knowledge, which shows up across many items regardless of the topic being tested.

In what order should I study the domains?

Start with skills checklists, since they anchor real practice and cover personal care, safety, and infection control at once. Then study by weight: personal care and hygiene is the largest domain, followed by role and rights, safety, infection control, and basic nursing skills. Nutrition, elimination, mobility, and mental health round it out. Finish with mixed practice questions.

Do I have to memorize ranges for vital signs and other numbers?

Know normal adult ranges well enough to notice and report an abnormal value, and know what to report and to whom. You are not diagnosing. The knowledge test favors recognizing an abnormal finding and following the correct reporting chain over reciting precise textbook figures, though a review of standard ranges is worth your time.

If I fail one part, do I retake both?

That depends on the rules in effect from the state-approved testing vendor, and policies change. Some candidates retake only the failed component; others must repeat both. Confirm with the vendor before you re-register, and check whether any waiting period or fee applies to your situation.

How much time do I get for the written test, and what score do I need?

The official testing body publishes the current time limit and passing standard, and those figures are revised periodically, so check the vendor's candidate handbook or website rather than relying on what a classmate told you. Your training program can also point you to the version that applies to your test date.

Is the oral knowledge test easier than the written one?

It is not easier or harder in content - it delivers the same material with the questions read aloud, which helps candidates with reading difficulties or for whom English is a second language. Eligibility rules apply, so ask the vendor whether you qualify before assuming you can choose the oral format.

Can I work while I wait for my results or a retake?

Typically you cannot perform nurse aide duties for pay until you are credentialed, though some employers hire aides in a non-direct-care or supervised training capacity. Ask the employer directly about their policy and check the state's rules on provisional employment, because the answer affects your start date and income.
