Free Practice Questions for Ohio CNA (formerly STNA)

Ohio CNA exams are administered by Headmaster (D&S Diversified Technologies) under the Ohio Department of Health (ODH). Ohio law uses the certified nurse aide (CNA) designation; many employers still say STNA. All Ohio test sites use electronic TMU testing. Schedule in the Ohio TMU portal at oh.tmutest.com; the candidate handbook and forms are on hdmaster.com/ohio/ohio-cna.

STNA stands for State Tested Nurse Aide, the title Ohio long used for its nurse aides. Since October 24, 2024, Ohio Revised Code 3721.32(E) says an individual listed on the Nurse Aide Registry in good standing is referred to as a certified nurse aide (CNA), and the current Headmaster candidate handbook uses CNA. To be listed, you must complete an ODH-approved NATCEP training program (or an approved alternate pathway) and pass both the knowledge exam and the skill test through Headmaster.

The Ohio CNA exam costs $120 for knowledge + skills ($30 knowledge + $90 skills). The optional audio knowledge exam costs $40, for a $130 total with the skill test. These fees took effect September 1, 2025, per the December 2025 Headmaster candidate handbook. Pay in your TMU account before scheduling.

You need 70% or better on the knowledge exam (about 56 of 79 questions correct). On the skill test, you must correctly perform every key (bolded) step and 80% of the non-key steps on each of your 3 or 4 tasks. The knowledge exam has 79 questions with a 90-minute time limit; the skill test allows 35 minutes.

Ohio has no fixed renewal date. ODH keeps you listed as eligible to work in long-term care when it has verification that you performed at least 7.5 consecutive hours, or 8 hours in a 48-hour period, of paid nursing and nursing-related services during the 24 months after you were placed on the registry or after your most recent verified work. Long-term care facilities can report employed aides on form HEA 7713. If more than 24 consecutive months pass without verified work, you must document qualifying work or complete additional training and competency evaluation. The Ohio Nurse Aide Registry is maintained by the Ohio Department of Health (ODH).

Yes, nursing students enrolled in pre-licensure nursing programs may waive the NATCEP training requirement with ODH approval. They must still pass both the knowledge exam and clinical skills evaluation through Headmaster to be listed on the Ohio Nurse Aide Registry.

Report suspected abuse, neglect, exploitation or misappropriation of resident property right away through your facility (the nurse or supervisor), as federal nurse aide training requires. Federal rules also require every employee of a federally funded long-term care facility to report a reasonable suspicion of a crime against a resident to the state survey agency and law enforcement: within 2 hours if there is serious bodily injury, otherwise within 24 hours. In Ohio anyone may also report directly to the director of health (ORC 3721.22(B)), and good-faith reporters are protected (ORC 3721.22(C) and 3721.24). Ohio's statutory duty to report to the facility (ORC 3721.22(A)) names licensed health professionals, not nurse aides. Separately, Ohio's adult protective services law (ORC 5101.63) requires employees of nursing homes, home health agencies and hospitals who have reasonable cause to believe that an adult aged 60 or older who, because of the infirmities of aging or a physical or mental impairment, cannot provide for their own care or protection and who lives in the community (an independent living arrangement, not a nursing home) is being abused, neglected or exploited to report it immediately to the county department of job and family services. The Ohio Nurse Aide Registry maintains records of substantiated findings of abuse, neglect, or misappropriation.
