Free Missouri CNA Practice Test 2026 — 75-Question HDmaster Exam

Missouri's exam is genuinely different from most states' — different question count, shorter time limit, a higher passing score, and its own content domains. Here's what every Missouri candidate needs to know: • Exam vendor: HDmaster (D&S Diversified Technologies), on behalf of the Missouri Department of Health and Senior Services (DHSS) • Written exam: 75 questions, 60 minutes — not the 70-question/2-hour format most states use • Passing score: 80% — higher than the 70% most states require • Skills exam: 3-4 randomly selected nurse aide skills (not the usual 5) • Exam fee: Knowledge exam $32 + Skills test $103 = $135 total • Retake limit: must pass both the knowledge and skills exams within 1 year of your training start date • Registry: Missouri Nurse Aide Registry, maintained by DHSS • Registry validity: 24 months; must work at least 8 paid hours as a nurse aide per renewal period If you've studied using a generic "70 questions in 2 hours, 70% to pass" practice test, recalibrate — Missouri's real bar is higher and the clock moves faster.

To become a Certified Nurse Aide in Missouri, you must pass the Missouri Nurse Aide Competency Evaluation — a two-part exam administered by HDmaster on behalf of the Missouri Department of Health and Senior Services (DHSS). The exam consists of: • A written (or oral) knowledge test: 75 multiple-choice questions, 60 minutes • A clinical skills evaluation: you will be asked to demonstrate 3 to 4 randomly selected nurse aide skills You must pass both parts to be listed on the Missouri Nurse Aide Registry. The passing score for the written test is 80% — noticeably higher than the 70% most other states require.

Missouri uses its own content-area breakdown rather than the standard national NNAAP six-topic split. The 75 questions are drawn from: • Safety (9 questions) • Personal Care (8 questions) • Infection Control (8 questions) • Basic Nursing Skills (8 questions) • Communication (6 questions) • Disease Process (6 questions) • Mental Health (6 questions) • Aging Process and Restorative Care (5 questions) • Care of the Cognitively Impaired (5 questions) • Resident Rights (5 questions) • Role and Responsibility of the Nurse Aide (5 questions) • Data Collection (4 questions) Safety and Personal Care carry the most weight, but Missouri's spread is far more even than most states' — there's no single dominant 45% category to concentrate on, so broad coverage across all twelve areas matters more here than in most states.

The Missouri CNA exam is administered at HDmaster testing centers across the state. Major testing locations include: • St. Louis area • Kansas City area • Springfield • Columbia • Jefferson City • Joplin To find the exact address and available test dates near you, go to hdmaster.com and search for Missouri nurse aide testing. You must register with HDmaster before scheduling — your training program will provide you with authorization to test once you complete your state-approved CNA course. Test dates fill up quickly in urban areas. Schedule as soon as you receive your authorization to test.

The clinical skills evaluation is conducted at a separate HDmaster skills testing facility. You will be evaluated by a trained skills evaluator. Missouri tests 3 to 4 skills — fewer than the 5 most states require — randomly selected from the full list of NNAAP skills. Commonly tested skills in Missouri include: • Handwashing • Indirect care (PPE donning and doffing) • Measuring and recording blood pressure • Providing catheter care for a female resident • Positioning a resident in Fowler's position • Assisting a resident to transfer from bed to wheelchair • Providing passive range of motion for the shoulder You do not need to perform the skills perfectly, but you must complete all critical steps. The handwashing skill is always evaluated as part of every other skill — you will wash your hands at the beginning and end of each skill demonstration.

Missouri's 80% passing score is higher than most states, and the exam moves faster — 60 minutes for 75 questions, under a minute per question. Students who use practice tests consistently perform significantly better. Recommended study approach: 1. Take a full 75-question diagnostic practice test before you start studying. Identify your weakest topics across all twelve Missouri content areas, not just the usual six. 2. Prioritize Safety and Personal Care — the two largest categories — but don't neglect the smaller ones; Missouri's spread is even enough that no single area carries you. 3. Practice under real time pressure. At 60 minutes for 75 questions, you have less breathing room than the national-average pacing most generic practice tests assume. 4. Take full practice tests under timed conditions. Aim for 85% or higher before your test date — that's a real buffer above Missouri's 80% passing bar. 5. For the skills test, practice each skill from start to finish including handwashing. Have someone watch you and check off the steps. CertPrepAcademy.com offers a free NNAAP-style practice test with 500+ questions across all content areas — no signup required. Use it to identify exactly where you need to focus before your Missouri exam.

Once you pass both parts of the Missouri exam, your name is added to the Missouri Nurse Aide Registry maintained by the Missouri DHSS. Employers are required by law to verify that a CNA is listed on the registry before hiring. Your Missouri CNA certification is valid for 24 months. To maintain your listing on the registry, you must work as a nurse aide for pay for at least 8 hours during each 24-month renewal period. If you let your certification lapse, you must retake the full exam. You can verify your registry status or look up another CNA's status at the Missouri DHSS nurse aide registry website.
