What the Skills Test Really Measures
Half of nurse-aide certification is a practical test. Under the National Nurse Aide Assessment Program (NNAAP), run by Credentia in California and many other states, you perform five skills in 30 minutes in front of a Nurse Aide Evaluator, on a volunteer playing a weakened elderly resident, and you must receive Satisfactory on all five. Each skill is a numbered list of steps from the candidate handbook; some steps are printed in bold — Critical Element Steps — and missing any one of them fails the skill on its own.
The test is not about speed or bedside charm. It is about performing every listed step, in a safe order, out loud enough that the evaluator can tick it. This guide explains the rules, lists the skills, pulls out the steps that repeat in almost every skill, and shows the tolerances the measurement skills are marked against. The written half of the exam is covered in our written-exam content guide, and both halves can be practised with our free CNA questions.
The Numbers
| Item | NNAAP Skills Evaluation (2024 candidate handbook) |
|---|---|
| Skills performed | 5 — hand hygiene plus four randomly selected |
| Time limit | 30 minutes for all five |
| Passing standard | Satisfactory on 5 of 5; one Unsatisfactory fails the evaluation |
| Measurement skill | At least one of the four random skills: blood pressure, radial pulse, respirations, urinary output or weight — recorded on a Recording Sheet |
| Skills in the pool | 22 (23 where the state tests electronic blood pressure in place of manual) |
| Critical Element Steps | Printed in bold; omitting one fails the skill regardless of the rest |
| Passing a skill | All Critical Element Steps and enough of the other steps to meet that skill's cut score |
| Who plays the resident | Another candidate, acting as a weakened elderly person |
| Results | Pass/fail per skill; a failing report lists the step numbers missed |
| Attempts (California) | Both parts must be passed within 24 months of training; three attempts per part before retraining |
The Skills You Can Be Asked to Perform
The handbook lists the skills alphabetically after hand hygiene, which is always first. What each one is really testing:
| Skill | What the evaluator is watching for |
|---|---|
| Hand hygiene (hand washing) | At least 20 seconds of friction, fingertips down, nails cleaned, paper towel to turn off the tap, never touching the sink |
| Applies one knee-high elastic stocking | Resident lying down, stocking turned inside-out to the heel, no twists or wrinkles at the end |
| Assists to ambulate using a transfer belt | Non-skid footwear, locked wheels, belt over clothing, upward grasp, walk ten feet slightly behind and to the side |
| Assists with use of a bedpan | Head of bed down to place and remove, gloves on and off at the right moments, toilet tissue and hand wipe within reach |
| Cleans upper or lower denture | Sink lined or part-filled, moderate-temperature water, clean technique for the brush and cup |
| Counts and records radial pulse | One full minute; recorded within ±4 beats of the evaluator's count |
| Counts and records respirations | One full minute; within ±2 breaths of the evaluator's count |
| Donning and removing PPE (gown and gloves) | Gown then gloves on; gloves off first, gown off without touching the outside |
| Dresses client with an affected (weak) right arm | Weak arm dressed first, undressed last; no pulling on the affected limb |
| Feeds client who cannot feed self | Resident upright, food identified, small bites, offered fluids, mouth and hands cleaned after |
| Gives modified bed bath (face and one arm, hand and underarm) | Water temperature checked, washcloth mitt, eyes inner to outer with a clean part of the cloth, rinsed and dried, privacy kept |
| Measures and records electronic blood pressure (state specific) | Correct cuff placement and a correctly recorded reading |
| Measures and records urinary output | Poured into a graduate at eye level on a flat surface; within ±25 mL of the evaluator's reading |
| Measures and records weight of an ambulatory client | Scale zeroed, resident steady, within ±2 lb (0.9 kg) of the evaluator's reading |
| Performs modified passive range of motion for one knee and one ankle | Supported joints, slow movements, at least three repetitions, stop at pain |
| Performs modified passive range of motion for one shoulder | Same principles; the arm supported at the elbow and wrist |
| Positions on side | Resident turned toward you with the rail up on the far side, pillows behind the back, between the knees and under the arm, body aligned |
| Provides catheter care for a female | Cleaning four inches of tubing away from the meatus with a clean area of the cloth for each stroke; tubing never pulled |
| Provides foot care on one foot | Water temperature checked, foot soaked and washed, dried between the toes, lotion not between the toes |
| Provides mouth care | Resident upright, gloves on, all surfaces brushed, mouth rinsed with a basin held to the chin |
| Provides perineal care for a female | Front to back, a clean area of the cloth for each stroke, rinsed and dried, linen protector used |
| Transfers from bed to wheelchair using a transfer belt | Chair positioned and locked, footrests up, non-skid shoes, belt grasped upward, pivot, resident seated with hips back |
| Measures and records manual blood pressure | Cuff on bare arm at heart level, stethoscope placement, within ±8 mmHg of the evaluator's reading for both numbers |
The Measurement Skills and Their Tolerances
Every candidate performs at least one measurement skill and records the result on a Recording Sheet. The evaluator takes the same measurement, and your recorded value must fall inside a set tolerance of theirs — the number itself is a step, so a technically perfect performance with a wrong reading fails.
| Skill | Tolerance | Where candidates go wrong |
|---|---|---|
| Radial pulse | ±4 beats per minute | Counting 30 seconds and doubling (the skill requires a full minute); using the thumb |
| Respirations | ±2 breaths per minute | Telling the resident they are being counted (they change their breathing); counting less than a full minute |
| Manual blood pressure | ±8 mmHg, systolic and diastolic | Cuff over clothing, wrong cuff size, deflating too fast, not inflating high enough |
| Weight of an ambulatory client | ±2 lb (±0.9 kg) | Not zeroing the scale; resident holding on to something |
| Urinary output | ±25 mL | Reading the graduate from above instead of at eye level on a flat surface |
Write the reading on the sheet immediately, in the units on the form, and write the complete blood pressure (both numbers). A reading not recorded is a reading not taken.
How Candidates Actually Fail
- Missing a Critical Element Step. Locking the wheels before a transfer, checking water temperature before a bath, keeping the resident covered during peri-care — bold steps that are safety steps. One omission fails the skill.
- Forgetting the ending. Signalling device within reach and bed in low position are separate steps in most bed skills; leaving the bed raised is the classic lost skill.
- Glove errors. Touching clean items with dirty gloves, or removing gloves in a way that touches the outside surface, then not washing hands.
- Measuring wrong. A pulse counted for 30 seconds, respirations announced, a scale not zeroed — the tolerance is generous only if the technique is right.
- Running out of time. Thirty minutes for five skills is enough when you move steadily; it is not enough if you restart a skill from the top after each hesitation. If you miss a step, say so, name the step and perform it — the handbook lets you correct steps without redoing the skill, and the evaluator scores steps, not smoothness.
- Doing the step but not showing it. Silently glancing at the wheels is not the same as saying and demonstrating that they are locked.
A Two-Week Practice Plan
Days 1–3: read the full skills listing in the handbook once, then copy out the bold steps only — they are your non-negotiables. Days 4–8: practise two skills a day on a friend or a pillow, narrating every step from the list; time each skill. Days 9–12: run full five-skill sets in 30 minutes, always starting with hand hygiene and including one measurement skill; have your practice partner check the tolerance. Days 13–14: drill only the skills you dropped a step on, and reread the shared steps above. On test day arrive early, ask any equipment questions before the evaluation begins (no help is allowed once it starts), and wash your hands when directed at the end.
Frequently Asked Questions
How many skills are on the CNA skills test?
Five: hand hygiene, which every candidate performs first, plus four randomly selected from the handbook list, one of which is a measurement skill. You have 30 minutes and must pass all five.
What is a Critical Element Step?
A step printed in bold in the handbook's skills listing. Leaving it out or performing it incorrectly fails the skill on its own, but performing only the bold steps does not pass it — you also need enough of the remaining steps to meet the skill's cut score.
How close does my blood pressure reading have to be?
Within ±8 mmHg of the evaluator's reading for both the systolic and the diastolic number. Pulse must be within ±4 beats, respirations within ±2 breaths, weight within ±2 lb (0.9 kg) and urinary output within ±25 mL.
Can I restart a skill if I make a mistake?
Yes, without redoing the whole skill: say that you made a mistake, tell the evaluator which step you are correcting, and perform it. Two exceptions in the handbook: if the evaluator has to remind you to put on or take off gloves, the correction earns no credit; and when you correct an order-dependent step you must say when it should have been performed. There is no extra time — the 30 minutes covers all five skills.
What happens if I fail one skill?
You fail the skills evaluation and retake the whole five-skill test, not just that skill. The failing score report lists the step numbers you missed under each Unsatisfactory skill, which is exactly what to practise. In California you have three attempts within 24 months of your training.
