A BLS Certificate Shows You Know CPR and Basic Life Support

A BLS certificate is a card or document that shows you have completed a course in cardiopulmonary resuscitation (CPR) and basic life support techniques. The course teaches you how to recognize when someone's heart has stopped or they have stopped breathing, and how to perform chest compressions and rescue breathing until emergency responders arrive.

The certificate itself is proof that you passed the course and the skills test. Most BLS certificates are valid for two years from the date you pass. After that, you need to take a renewal course to keep the certificate current. Many employers require their staff to hold a current BLS certificate, especially in healthcare, childcare, fitness, and emergency response roles.

BLS training is different from CPR-only training. A BLS course covers CPR but also includes other skills like using an automated external defibrillator (AED), recognizing stroke and heart attack symptoms, and performing rescue techniques for choking. CPR-only courses focus narrowly on chest compressions and rescue breathing.

Key Takeaways

  • A BLS certificate proves you completed training in CPR and basic life support techniques and passed a skills test.
  • Most BLS certificates remain valid for two years, after which you must take a renewal course to keep current.
  • BLS training includes CPR, AED use, and recognition of cardiac and stroke emergencies—broader than CPR-only courses.
  • The American Heart Association and the Red Cross are the two main organizations that issue BLS certificates in the United States.
  • Many healthcare employers, childcare facilities, and fitness centers require staff to hold a current BLS certificate.

Who Issues BLS Certificates

Two major organizations issue BLS certificates in the United States: the American Heart Association (AHA) and the American Red Cross. Both are recognized nationally, and most employers accept certificates from either organization. Some states or specific employers may have a preference, so check your workplace requirements before enrolling.

Both organizations train instructors who then teach BLS courses. You take the course from an instructor certified by one of these organizations, and if you pass, you receive a certificate bearing that organization's name. The course content is similar between the two, though the exact skills stations and testing procedures may differ slightly.

Some hospitals, universities, and large employers run their own BLS training programs using instructors they have certified. These in-house programs still follow the standards set by the American Heart Association or Red Cross, and the certificates they issue are recognized the same way.

What You Learn in a BLS Course

A standard BLS course takes four to six hours and covers several core skills. You learn how to perform high-quality chest compressions at the correct depth and rate, how to deliver rescue breaths using a bag-valve-mask device, and how to use an AED safely. The course also teaches you to recognize the signs of a heart attack, stroke, and severe choking, and what to do in each situation.

Most of the course is hands-on practice. You will practice chest compressions on a mannequin, learn to position an unconscious person, and practice using an AED trainer. The instructor will watch you perform these skills and give you feedback. At the end, you take a written test and a practical skills test where you demonstrate CPR and AED use on a mannequin while an instructor observes.

The course also covers when to call 911, how to give clear information to the dispatcher, and how to work as part of a team if other responders are present. You will learn the recovery position, which is how to place an unconscious person who is breathing so they do not choke if they vomit.

How the Skills Test Works

To earn your certificate, you must pass both a written exam and a practical skills test. The written exam is usually multiple choice and covers the material from the course—how to recognize emergencies, when to call 911, and the steps of CPR and AED use. Most people pass this part without trouble if they paid attention during the course.

The skills test is where most people focus their effort. You will be asked to perform CPR on a mannequin while an instructor watches and scores you. The instructor checks that you are compressing at the right depth (usually 2 to 2.4 inches for an adult), at the right rate (100 to 120 compressions per minute), and allowing the chest to recoil fully between compressions. You will also demonstrate how to use an AED and how to deliver rescue breaths if required by your course type.

You do not have to be perfect, but you do have to meet the minimum standard. If you do not pass on your first attempt, you can usually retake the skills test the same day or within a few days. Most instructors will give you extra practice time if you ask.

How Long a BLS Certificate Lasts

A BLS certificate is valid for two years from the date you pass the course. Some organizations or employers may have different rules—for example, a hospital might require renewal every year, or a specific program might accept a certificate that is up to three years old. Always check with your employer or the organization that requires the certificate.

When your certificate is about to expire, you can take a renewal course. A renewal course is shorter than the initial course, usually two to four hours, because you already know the material. You still take a written test and skills test to renew.

If your certificate expires and you need it for your job, you will need to take a full initial course again, not a renewal course. Some employers will give you a grace period to renew before they require you to stop working, but this varies. It is easier to renew before your certificate expires.

Where to Take a BLS Course

You can take a BLS course at hospitals, community colleges, fire departments, the Red Cross, American Heart Association training centers, and many private training companies. Some courses are offered in person only, while others offer a blended format where you watch videos at home and then come in for a shorter in-person skills session.

Costs vary depending on where you take the course. In-person courses typically cost between $50 and $150. Online or blended courses may cost less. Some employers pay for their staff to take BLS training, so ask your workplace before you pay out of pocket.

When you choose a course, make sure the instructor is certified by the American Heart Association or Red Cross. You can check the American Heart Association website or Red Cross website to find courses in your area. If you need the certificate for a specific job, ask your employer which organization they prefer and whether they have a list of approved training providers.

BLS Certificate vs. Other CPR Certifications

BLS is broader than CPR-only certification. A CPR-only course teaches chest compressions and rescue breathing but does not include AED training or recognition of other emergencies like stroke. BLS includes all of that plus more.

Some organizations offer ACLS (Advanced Cardiac Life Support), which is a more advanced course for healthcare workers. ACLS builds on BLS and teaches how to manage cardiac emergencies using medications and advanced techniques. You usually need a current BLS certificate before you can take ACLS.

There is also First Aid certification, which covers a wider range of injuries and illnesses but does not go as deep into CPR as BLS does. Many people hold both BLS and First Aid certificates.

Frequently Asked Questions

Can I take a BLS course entirely online?

Most organizations require at least some in-person time for the skills test, even if you watch the lecture portion online. A few organizations offer fully online courses with a skills test done by video, but these are less common and not accepted everywhere. Check with your employer about whether an online-only course will meet their requirements.

What happens if I fail the skills test?

You can usually retake the skills test the same day or within a few days at no extra cost. The instructor will give you feedback on what you need to improve. Most people pass on the second attempt. If you fail multiple times, you may need to retake the full course.

Do I need to renew my BLS certificate if I am not working?

If you are not using the certificate for a job or volunteer position, you do not have to renew it. However, if you ever need it again for employment, you will need to take a full initial course if your certificate has expired.

Is a BLS certificate from one organization accepted by employers who require the other?

In most cases, yes. The American Heart Association and Red Cross certificates are both widely recognized and accepted. However, some specific employers or states may have a preference. Ask your employer or the organization requiring the certificate before you enroll.

How much does a BLS course cost?

In-person BLS courses typically cost between $50 and $150, depending on the provider and location. Blended or online courses may cost less. Some employers cover the cost for their staff, so check with your workplace before paying out of pocket.
