BLS Certification Is a Card That Shows You Know CPR and Basic Life Support

BLS certification from the American Heart Association is a credential that documents you have completed training in cardiopulmonary resuscitation (CPR) and other emergency life support techniques. The card itself is proof that you passed a course and exam within the last two years. It does not mean you work in healthcare — many workplaces, volunteer roles, and licensing boards straightforward require it as a condition of employment or membership.

The American Heart Association is the organization that sets the standards for BLS training in the United States. When you take a BLS course from an authorized instructor, you learn how to perform chest compressions, use an automated external defibrillator (AED), and respond to choking. The course takes between four and eight hours depending on whether you are renewing or taking it for the first time. At the end, you take a written exam and a skills test — you have to show that you can actually perform CPR correctly on a mannequin.

If you pass both parts, you receive a card valid for two years. After that, you must renew. The card is what employers, schools, and licensing boards ask to see. Without it, you cannot work in many positions even if you know how to do CPR.

Key Takeaways

  • BLS certification is a two-year card proving you completed CPR and emergency response training from an American Heart Association-authorized course.
  • The course includes both classroom instruction and hands-on practice with a mannequin, ending with a written test and a skills demonstration.
  • Many employers — hospitals, schools, childcare centers, fitness facilities — require BLS certification as a condition of hire.
  • You must renew your card every two years; renewal courses are shorter than initial certification and cost less.
  • You can take BLS courses in person or online (though the skills test must happen in person with an instructor).

Who Needs BLS Certification and Why

Healthcare workers are the most common group required to hold BLS certification. Nurses, paramedics, emergency medical technicians, and physicians all need it. But the requirement extends far beyond hospitals. Childcare workers, school staff, personal trainers, lifeguards, and security personnel often need BLS as part of their job. Some volunteer positions — coaching, mentoring, working at community centers — also require it.

Employers require BLS certification because it shows you can respond correctly if someone has a cardiac event or stops breathing. The first few minutes after cardiac arrest are critical; someone trained in CPR can keep blood flowing to the brain and heart until emergency services arrive. A person without training may freeze or perform CPR incorrectly, which can cause injury or death.

Licensing boards in some fields also mandate BLS. If you are pursuing a nursing license, emergency medical technician certification, or certain other credentials, you will need to show current BLS certification before you can sit for the licensing exam or before your license is issued.

What You Learn in a BLS Course

A BLS course covers several core skills. You learn how to recognize when someone is unresponsive and not breathing normally, and how to call 911 or direct someone else to do so. You practice chest compressions — the rhythm, the depth, the hand placement — on a training mannequin. You learn how to use an AED, which is a portable device that can shock a heart back into a normal rhythm. You also learn how to respond to choking in adults, children, and infants.

The course includes scenarios where you practice these skills in realistic situations. An instructor will walk you through what to do if you find someone collapsed in a parking lot, or if someone chokes during a meal. You learn to work as part of a team if other trained people are present. The goal is to make the skills automatic so that in a real emergency, you do not have to think — you act.

The written exam tests your knowledge of when to call 911, how to recognize a stroke, what to do if someone is choking, and how to use an AED. The skills test requires you to perform CPR on a mannequin while an instructor watches and scores you on technique, rate, and depth of compressions.

Initial Certification Versus Renewal

An initial BLS certification course is longer and more thorough because you are learning everything from scratch. These courses typically run four to eight hours depending on the provider and whether you are taking it as a standalone course or as part of a larger healthcare training program. You pay more for initial certification — costs range widely but often fall between $60 and $150.

Renewal courses are shorter because you already know the material. A renewal course usually takes two to four hours and focuses on updates to guidelines, refreshing your skills, and making sure you still remember how to perform CPR correctly. Renewal costs less, typically $40 to $100. You must renew before your card expires; if it lapses, you have to take the full initial course again, not a renewal.

Some providers offer online learning for the classroom portion of both initial and renewal courses, but the skills test must happen in person with an instructor present. You cannot pass the hands-on portion of BLS certification remotely.

Where to Take a BLS Course

The American Heart Association does not run courses directly. Instead, it authorizes training centers and instructors to teach BLS using American Heart Association materials and standards. You can find authorized providers through the American Heart Association website by entering your zip code. Training centers include hospitals, community colleges, American Red Cross chapters, and private training companies.

Hospitals often offer BLS courses to their employees and sometimes to the public. Community colleges frequently run BLS courses as part of their continuing education programs. The American Red Cross also teaches BLS and uses similar content, though their certification is separate from the American Heart Association. Private training companies offer BLS courses in many cities and often have more flexible scheduling than hospitals or colleges.

When you choose a provider, confirm that they are authorized by the American Heart Association. The card you receive will say "American Heart Association" on it only if the course was taught by an authorized provider using American Heart Association curriculum. A course taught by an unauthorized provider will not give you an American Heart Association card, even if the content is similar.

Cost and How Long the Card Lasts

Initial BLS certification costs between $60 and $150 depending on your location and the provider. Renewal costs between $40 and $100. Some employers cover the cost for their employees; ask your workplace before you pay out of pocket. Some health insurance plans reimburse training costs, though this is less common.

Your BLS card is valid for exactly two years from the date you pass the course. After two years, it expires and is no longer recognized by employers or licensing boards. You can renew up to 30 days before your card expires, so you do not have to wait until the last moment. If your card expires before you renew, you must take a full initial course again, which costs more and takes longer.

Some employers give you a grace period to renew after your card expires, but this is not may provide. It is safer to renew before expiration. Many people renew their BLS certification at the same time every two years to avoid accidentally letting it lapse.

Online Versus In-Person BLS Courses

Many providers now offer a blended approach: you complete the classroom portion online at your own pace, then attend an in-person session for the skills test and exam. This saves time if you already understand CPR basics or if you are renewing. The online portion usually takes one to three hours, and the in-person session takes one to two hours.

Some providers offer fully in-person courses where you attend the entire class in one session, usually four to eight hours. These courses are more interactive and may be better if you are learning CPR for the first time or if you prefer hands-on instruction from the start.

A few providers offer fully online courses, but these do not include the skills test. You still have to schedule a separate in-person appointment with an instructor to demonstrate that you can perform CPR correctly. The online course alone does not result in certification.

What Happens If You Fail the Exam or Skills Test

If you do not pass the written exam or the skills test on your first attempt, most providers allow you to retake it the same day or within a few days at no extra cost. You might need to review the material or practice the skills again with the instructor before retaking the test. If you fail a second time, some providers charge a fee for additional attempts, while others include unlimited retakes in the course fee.

If you fail and decide not to retake the test when ready, you do not receive a card. You have to complete the course again, including paying the full course fee, to earn certification. There is no partial credit or "almost passed" status — you either pass and get the card, or you do not pass and do not get the card.

Frequently Asked Questions

Do I need BLS certification if I work in an office and have no medical duties?

Most office jobs do not require BLS certification. However, some workplaces require all employees to hold it regardless of role, or they may require it if you are a manager or safety coordinator. Check your employee handbook or ask your HR department. If your job does not require it, you can still take the course voluntarily.

Can I use BLS certification from another organization instead of the American Heart Association?

It depends on your employer or licensing board. Many accept BLS certification from the American Red Cross or other authorized providers. However, some specifically require American Heart Association certification. Always check the requirement before taking a course with a different organization.

What if my BLS card expires while I am waiting for a renewal course?

Your card is no longer valid the moment it expires. If you have not yet taken a renewal course, you are technically not certified. Some employers give a short grace period, but do not count on it. Schedule your renewal course before your expiration date to avoid this problem.

Do I have to retake BLS certification if I change jobs?

No. Your BLS card is valid at any employer for the full two years. You do not need a new card when you change jobs. However, your new employer may have different requirements — for example, they might require a specific type of BLS course or additional certifications beyond BLS.

Can I take a BLS course online and get certified without going in person?

No. The skills test — demonstrating that you can perform CPR correctly on a mannequin — must be done in person with an instructor watching. You can complete the classroom portion online, but you must attend an in-person session for the hands-on evaluation and to receive your card.
