What happens during a CPR certification test

A CPR certification test has two parts: a written exam and a hands-on skills test. The written portion is usually 10 to 15 multiple-choice questions about CPR technique, when to call 911, and what to do if someone is choking or unresponsive. You typically need to score 80 percent or higher to pass. The skills test requires you to perform chest compressions and rescue breaths (or hands-only CPR) on a mannequin while an instructor watches and scores your technique against a checklist.

The entire test usually takes 30 to 60 minutes depending on the organization running it. The American Red Cross, American Heart Association, and other training providers all use similar formats, though exact requirements vary slightly. Most instructors will tell you the passing standards before the test begins, so you know what depth of compression, hand placement, and compression rate they are looking for.

Key Takeaways

  • The written test is usually 10 to 15 multiple-choice questions, and you need to score 80 percent or higher to pass.
  • The skills test requires you to perform chest compressions and rescue breaths on a mannequin while an instructor scores your technique against a specific checklist.
  • Chest compressions should be 2 to 2.4 inches deep at a rate of 100 to 120 compressions per minute, with your hands positioned on the center of the chest.
  • Practice on the actual mannequin your instructor uses before the test, because different models have different resistance and feedback.
  • If you fail either part, most providers let you retake that section within a few days or weeks at no extra cost.

Chest compression depth and hand placement

The most common reason people fail the skills test is incorrect compression depth or hand placement. Your hands must be positioned on the center of the chest, between the nipples, with the heel of one hand on the breastbone and your other hand stacked on top. Keep your arms straight and use your body weight to push down, not just your arm muscles.

Compressions must be 2 to 2.4 inches deep—deep enough that the mannequin's chest visibly rises and falls, but not so deep that you crack ribs (on a real person). The compression rate is 100 to 120 compressions per minute. Many instructors recommend counting to the beat of the song "Stayin' Alive" by the Bee Gees, which is roughly 103 beats per minute and matches the required pace. Push hard and push fast, and do not pause between compressions except to deliver rescue breaths if you are trained to do so.

Rescue breaths and the recovery position

If your certification includes rescue breaths, you will need to demonstrate them on the mannequin. After 30 compressions, open the airway by tilting the head back slightly and lifting the chin. Pinch the nose closed, seal your mouth over the mannequin's mouth, and blow for one second until you see the chest rise. Give two rescue breaths, then return to compressions when ready. The entire cycle—30 compressions and 2 breaths—should take about 24 seconds.

Some certifications teach hands-only CPR, which skips rescue breaths and focuses entirely on chest compressions. Ask your instructor which method your test will cover. If the test includes the recovery position, you will need to roll an unresponsive person onto their side with one leg bent to keep them stable, and tilt their head back to keep the airway open. Practice this movement before the test so you can do it smoothly without hesitation.

Written test topics to study

The written portion covers recognizing cardiac arrest, when to call 911, how to use an automated external defibrillator (AED), and what to do for choking. Study the specific course materials your instructor provided—do not rely on general internet searches, because different organizations emphasize different details. Read through the manual at least twice, and pay special attention to any sections your instructor highlighted or spent extra time on during class.

Common written test questions ask about compression-to-breath ratios, the correct depth for child versus adult CPR, and when to stop performing CPR. Know that you should call 911 when ready if someone is unresponsive and not breathing normally, and that you should use an AED as soon as one is available. If you are unsure about a question during the test, read it carefully and eliminate answers that are clearly wrong before guessing.

Practice before the test day

Attend all training sessions and practice on the mannequin as much as possible during class. After class, ask your instructor if you can stay longer to practice, or ask if they have open practice sessions before the test. Different mannequins have different resistance—some require more force to compress than others—so practicing on the exact model you will be tested on makes a real difference.

If your training center offers practice tests or study guides, use them. Time yourself on the written portion so you know you can finish within the time limit. For the skills test, have someone watch you and give feedback on your hand placement and compression depth. Many people compress too shallowly because they are afraid of hurting the mannequin; remember that on a real person, you cannot make CPR worse by pushing too hard.

What to do if you fail

If you do not pass the written test, most providers will let you retake it within a few days at no extra cost. Review the questions you missed and study those topics more carefully before the second attempt. If you fail the skills test, ask your instructor exactly which part you did not meet the standard on—compression depth, rate, hand placement, or airway management. Practice that specific skill intensively before your retake.

Some training centers offer a brief refresher session before a retake, and some let you practice with the instructor one-on-one. Take advantage of these options. Failing a CPR test is common, and instructors expect to see people retake it. There is no penalty for retaking, and you will pass once you understand what the standard is and practice to meet it.

After you pass: maintaining your certification

CPR certifications are valid for two years from the date you pass the test. Your instructor will give you a card with your expiration date on it. Mark that date on your calendar now so you do not let it lapse. Some employers require CPR certification as a condition of employment, and letting it expire can cost you a job or require you to retrain when ready.

About three months before your certification expires, start looking for a renewal course. Renewal courses are shorter than initial training—usually one to two hours—and focus on updates and a skills check rather than teaching everything from scratch. You will still need to pass both the written and skills portions of the renewal test, so do not skip the practice.

Frequently Asked Questions

Can I use a different hand position if it feels more comfortable?

No. The heel of one hand on the center of the chest with your other hand stacked on top is the standard position, and your instructor will score you on whether you use it correctly. If the standard position is physically uncomfortable for you, tell your instructor before the test—they may have modifications or can document your situation.

What if I cannot remember the compression rate during the test?

Most instructors allow you to hum or count out loud during the skills test. If you know "Stayin' Alive" or another song at the right tempo, use it. Your instructor will not penalize you for counting or humming; they only care that your compressions are at the correct rate.

Do I have to do rescue breaths, or can I do hands-only CPR?

That depends on your course. Some certifications teach hands-only CPR for adults, while others require rescue breaths. Ask your instructor which method your test covers before the test day so you can practice the right technique.

How long does a CPR certification last?

CPR certifications are valid for two years from the date you pass. After that, you will need to take a renewal course and pass the test again to keep your certification current.

What happens if I fail the skills test but pass the written test?

Most providers let you retake just the skills portion at no extra cost within a few days or weeks. You do not have to retake the written test. Ask your instructor when the next skills-only retake session is scheduled.
