CNA skills exam practice: what each skill is scored on, and how to drill it with a class
In this article
What is actually scored
The exam is a checklist, and it is published
CNA skills exam practice works best when it is built around the same document the evaluator is holding, because the scoring is not a secret: every skill on the state exam is broken into numbered steps, those steps are published in the candidate handbook, and a few of them are printed in bold. The bold ones are Critical Element Steps. Miss one, or perform it wrong, and the skill is failed no matter how well the rest went.
This is what one looks like. Step 5 of hand hygiene, the skill that appears on every single test:
Lathers all surfaces of wrists, hands, and fingers producing friction, for at least 20 (twenty) seconds, keeping hands lower than the elbows and the fingertips down.
Two more, from skills that students find much harder. In perineal care, washing and rinsing have to move front to back, using a clean area of the washcloth for each stroke. In the transfer with a gait belt, the wheelchair wheels have to be locked and the resident’s feet have to be flat on the floor before anyone stands up. All three are in bold in the NNAAP skills listing, which means all three fail the skill on their own.
The rule most classes get wrong
Nailing the bold step does not pass the skill
The common shortcut is to teach the Critical Element Steps and treat the rest as detail. The handbook closes that door explicitly: “if you perform only the Critical Element Step correctly, you do not automatically pass that skill. You must also correctly perform enough steps to meet the passing standard (or cut score) for each skill.”
So the bold steps are necessary and not sufficient, and the rest of the numbered list is where the cut score is made up. Three more constraints shape how practice should be organized:
- Five skills, thirty minutes, all five have to pass. The candidate handbook is blunt about it: five out of five, with a warning from the evaluator when twenty-five minutes have gone by. Prometric, which administers the exam in a different set of states, also scores five skills and also requires all five.
- Handwashing is always one of them, and one of the remaining four is a measurement skill. That is two of five known in advance, which is a gift for anyone planning a syllabus.
- The evaluator will not help. They will not answer questions during the evaluation and will not say whether a skill went well. In Prometric’s own wording, the evaluator’s role is “to observe and record your performance.”
Where the failures actually are
Not all skills are equally hard, and the numbers say which
Prometric publishes pass rates per skill in its preparation material for programs, and they do not spread evenly. The gap between the easiest and the hardest skill is more than twenty points.
| Skill | Pass rate | The most common mistake |
|---|---|---|
| Measure and record pulse | 74 % | Counting for less than a full minute, or using the thumb |
| Catheter care | 83 % | Wiping back to front, or not holding the catheter at the meatus |
| Measure and record respirations | 86 % | Counting 30 seconds and doubling it |
| Perineal care | 87 % | Wiping back to front, or not rinsing |
| Range of motion, elbow and wrist | 87 % | Exercising the wrong side or the wrong joint |
| Transfer to wheelchair | 88 % | No shoes on, wheelchair not locked, feet not flat |
| Feeding | 88 % | Not offering a drink every two or three bites |
| Handwashing | 97 % | Lathering for less than 20 seconds |
Read the table as a syllabus, not as a prediction. Pulse and catheter care deserve several attempts each and an early slot in the term; handwashing needs one clean demonstration and then repetition inside every other skill. And read it with the caveat it deserves: these are Prometric’s figures, from its own states and its own skill list, so they point at where students struggle rather than at what any one student will score.
How to run it
A practice session for twenty students and one evaluator
The real classroom problem is not knowing what is scored, it is arithmetic: every student needs many attempts and there is one of you. This is the sequence that gets the most out of a single lab slot.
- Hand out your state’s official checklist in week one, not as an assessment but as the map of the course. It costs nothing, it is the exact document the evaluator will use, and half of exam-day anxiety is unfamiliarity with the form.
- Teach the bold steps first, in isolation. Ten minutes of front to back, clean area of the cloth for each stroke, nothing else. Students who learn the critical step as part of a twenty-step sequence forget it under pressure; students who learn it on its own do not.
- Order the term by pass rate, not by the alphabet. The published list is alphabetical for convenience. Your calendar should start with pulse, catheter care and transfer, which is where the failures concentrate.
- Have them score each other with the checklist in hand. The exam already puts every candidate in the resident’s role for someone else, so the practice is realistic on both sides. Scoring a peer against a numbered list is also the fastest way to learn what the numbered list means.
- Run one full rehearsal under exam conditions. Five skills, thirty minutes, no feedback, no questions answered. The first time a student performs unaided should not be the state exam.
- Practice the talking every single day, not on lab day. Greeting the resident by name, explaining what is about to happen, asking about preferences and placing the call light are scored inside every skill. They are also the part that a busy lab never rehearses.
Where the extra reps come from
The lab is finite, the rehearsal does not have to be
Steps 2 and 6 are the ones that break against the timetable. Both need volume, and the lab is booked. This is the gap CNA simulations fill: attempts that do not need the room, the manikin or your presence, so that the lab slot is spent on the physical technique that genuinely requires all three.
One case worth knowing if your cohort includes students who are new to English. A service cooperative in Minnesota had exactly that situation and solved it without adding instructors: CNA students rehearse the hard conversations, residents with dementia, agitated residents, coordinating with the care team, against AI patients on their own time, before their clinical placements. They built more than twenty scenarios of their own. The details are in the case study, and the bedside side of it is in the long-term care scenarios.
Said out loud
What this does not replace, and what to check before you plan
None of this replaces the lab. A student who has never physically applied a gait belt is not ready because they rehearsed the sequence on a screen, and no software puts hands on a real transfer.
Two things to verify before you build the term around anything written here. Your state’s checklist is the only one that counts: the two administrators do not test the same number of skills or grade them the same way, so download the current handbook for your state and teach from that. And check the edition date every year, because skill lists get revised.
If you are choosing tools for this, we wrote separately about what to look for in CNA training software and about rehearsing bedside skills in VR. And if you run a program, the field guide for CNA program directors collects the planning side of all this in one place.
Frequently asked
Questions people ask about this.
-
How many skills are on the CNA skills exam, and is handwashing always one of them?
Five. Handwashing is always included, and one of the other four is a measurement skill such as pulse, respirations, blood pressure, weight or urinary output. Under the NNAAP exam you have thirty minutes for all five and you have to pass all five.
-
What is a Critical Element Step?
It is a step printed in bold in the official skills listing. Leaving it out, or performing it wrong, fails that skill on its own. Performing it correctly does not pass the skill by itself: you still have to complete enough of the other steps to reach the cut score.
-
Do students have to pass all five skills?
Yes. Both administrators require five out of five in the same sitting. Failing one skill fails the skills evaluation, which is why rehearsing five in a row under time is worth more than rehearsing one skill perfectly.
-
Which CNA skill do candidates fail most often?
In the pass rates Prometric publishes, measuring and recording the radial pulse is the lowest at 74 %, followed by catheter care at 83 % and respirations at 86 %. The usual causes are counting for less than a full minute and wiping in the wrong direction.
