The CNA Skills Evaluation: How It Works and How It Is Scored

Who runs the CNA skills evaluation, and where

Federal rules set the frame for every state's skills demonstration (42 CFR 483.154):

• The skills come from a pool. You perform "randomly selected items drawn from a pool consisting of the tasks generally performed by nurse aides," and the pool must include every personal care skill in the federal training curriculum, from bathing and mouth care to transfers and positioning.
• The setting looks like work. The demonstration takes place in a facility or laboratory setting comparable to where you will work.
• A registered nurse evaluates you. The evaluator must be an RN with at least one year's experience caring for elderly or chronically ill people of any age.

Credentia's handbooks call this person a "Nurse Aide Evaluator" (Pennsylvania) or an "RN Nurse Aide Evaluator" (Tennessee). Before you start, the evaluator shows you where the equipment is and answers questions about how it works. After that, the evaluator will not answer questions or tell you how you are doing, so ask everything first. Pennsylvania's handbook asks you to arrive 30 minutes early and to plan to spend the day, because skills test times are approximate.

Five skills in 30 minutes: what the time looks like

On the NNAAP evaluation, as checked on October 18, 2026, in the Pennsylvania and Tennessee handbooks:

• Five skills. Hand Hygiene is always one. The other four are chosen at random from your state's list, and one of those four includes a measurement.
• One instruction card. The evaluator gives you a card listing your five skills. Pennsylvania strongly encourages you to do them in the card's order, and Tennessee asks you to.
• Thirty minutes in total. The evaluator tells you when 25 minutes have passed and 5 remain.
• All five must pass. You need five of five Satisfactory results.

Thirty minutes for five skills is six minutes per skill on average. That is arithmetic, not a rule, and real skills vary: hand washing is short, while a bed bath or a transfer takes longer. If your hand washing takes about 2 minutes, the other four average 7 minutes each. One rule helps with time: after your first hand washing, the evaluator tells you to just say when you would wash your hands during the remaining skills, rather than washing again each time.

Working with the candidate volunteer

Another candidate plays the resident, acting as "a weakened elderly person." Speak to that person as you would speak to a resident at work. The handbook encourages this as part of good care, and it notes that talking also helps you relax. Two rules are strict:

• No help, either way. If either candidate gives or receives help, the test is stopped.
• English only. Candidate and volunteer must speak to each other in English so the evaluator can score what is said.

You will also play the resident for someone else. Pennsylvania's handbook asks volunteers to wear flat, slip-on, non-skid shoes, a loose top with short sleeves that can roll up to the shoulder (or a tank top), and loose pants that can roll up. You wear a gown over your clothes, and no one undresses to underwear. Before the test, tell the evaluator about any food or latex allergy, any sensitivity to skin soaps or lotions, and any limits on your range of motion. If you have open sores on your skin, reschedule the skills test until they heal. That is an infection control rule, and it protects the candidate who will be caring for you.

Perform it, don't describe it

The skills evaluation scores what the evaluator sees you do. Credentia's tips make that concrete:

• Do every step for real. Apart from the hand-washing exception above, you cannot tell the evaluator you would wash or feed the resident. You must actually wash or feed.
• Use running water when a skill needs water.
• Bring no equipment of your own, such as a transfer or gait belt. The site provides what you need.
• Leave the call signal within the resident's reach whenever you step away from them.
• Introduce yourself once. After the first introduction, you do not have to repeat it at the start of each skill.

This is also how the job works. A resident is not helped by an aide who knows the steps but skips them under pressure.

How Critical Element Steps and the cut score decide each skill

Every NNAAP skill is broken into numbered steps, and some are printed in bold as Critical Element Steps. The handbooks set two conditions for passing a skill:

1. Every Critical Element Step must be done, and done properly. Leave one out, or do it wrong, and you fail the skill.
2. Doing the Critical Element Steps alone is not enough. You must also complete enough of the other steps to meet that skill's passing standard, or cut score.

This guide does not list which steps are critical. They are part of Credentia's copyrighted checklists, and your state's current version is the one that counts. Learn them from your handbook with your instructor. The 23 NNAAP skills explained covers the purpose behind each group of steps, which makes the checklist easier to remember.

Correcting a mistake on the skills evaluation, and the two exceptions

You can fix an error without starting the skill over. Say that you made a mistake, tell the evaluator which step you want to correct, and then do it. Two corrections earn no credit:

• Gloves after a reminder. If you fail to put on or take off gloves when a step requires it and the evaluator reminds you, correcting it earns no credit. The handbooks give infection control as the reason, so glove timing has to be right the first time.
• An order-dependent step without its timing. Some steps must come before or after another step. If you correct one of those, you must also say when it should have been done, or the correction does not count.

Once you begin a new skill, you cannot go back to fix an earlier one. Catch your errors before you move on.

Why one CNA skill is always a measurement

On the NNAAP, one of your four random skills always includes a measurement. As checked on October 18, 2026, the Pennsylvania list of recorded measurements is blood pressure, weight of an ambulatory resident, urinary output, radial pulse and respirations. Tennessee's list leaves out weight.

You record the measurement on a tablet and sign to confirm it. Full credit requires both an accurate measurement and an accurately recorded number. If weight is on your list, you must know how to use both a standing scale and a non-digital bathroom scale and how to set each one to zero.

The reason is in the job itself. Taking and recording vital signs, and measuring and recording height and weight, are core nurse aide skills in the federal curriculum (42 CFR 483.152(b)(2)), and nurses make decisions from those numbers. Vital signs and measurements covers the common sources of error.

State notes for the skills evaluation, as checked on October 18, 2026

• Tennessee attire. For both the knowledge and skills exams: full clinical attire with clinical shoes, no open-toed shoes, scrubs of any color or design, no smartwatches, smart glasses, fitness monitors or other Bluetooth devices, long hair pulled back, and clean fingernails no longer than ¼ inch. A candidate who does not meet these rules is treated as a no-show and forfeits the fee.
• Tennessee skill changes. Changed steps on Tennessee's skills list are tested from 11/1/2026, and Skills 2 (knee-high elastic stocking) and 19 (foot care) are tested from 12/1/2026. The 23 NNAAP skills explained lists the topics of the changes.
• Washington order. You take the in-person skills test first and register for the online (or oral) knowledge test after you pass it. The skills test cost is set by the training program.
• California timing. You do not need to take the written and skills parts on the same day, unless you register for the paper-pencil written or oral exam.
• Pennsylvania light duty. Pennsylvania's handbook says that "Federal law prohibits" anyone on restricted activity or light duty for medical reasons from taking the skills evaluation. We did not find that prohibition in the federal competency evaluation rule (42 CFR 483.154), so treat it as Pennsylvania's handbook rule. Light duty does not stop you from taking the written exam, and you need medical documentation of a return to full, unrestricted duty to reschedule the skills part.
• Skills not tested. Pennsylvania does not test the bedpan skill or electronic blood pressure. Tennessee does not test electronic blood pressure or weight.

After the CNA skills evaluation: the failing report

When the evaluation ends, the evaluator directs you to wash your hands. That does not affect your result. If you do not pass, the failing report lists your five skills, marks each Satisfactory or Unsatisfactory, and prints the numbers of the steps you missed under each failed skill. Use those numbers with your state's skills list to plan your practice. The CNA passing score guide walks through a sample report, and CNA exam day covers ID and what to bring. In Pennsylvania you need two forms of current, signature-bearing ID, one with a photo.
