BLS Certification Explained

BLS certification means you have completed a course in Basic Life Support and passed a test showing you can perform CPR, use an automated external defibrillator (AED), and respond to choking. The American Heart Association (AHA) issues the credential after you finish their training and pass a written and skills exam. The card you receive is valid for two years, after which you must renew it.

BLS is different from CPR-only certification. CPR alone teaches chest compressions and rescue breathing. BLS adds the use of an AED device and covers how to help a choking victim. Many healthcare workers, emergency responders, and people in certain jobs are required by their employer to hold current BLS certification. Some workplaces ask for it even when it is not legally required, because the training reduces liability and improves the chance that someone in the building can help during a cardiac emergency.

You do not need medical experience or a background in healthcare to take BLS. The course is designed for anyone who may need to perform CPR in a workplace or public setting. Most courses run four to six hours and include both classroom instruction and hands-on practice with a mannequin.

Key Takeaways

  • BLS certification shows you can perform CPR, use an AED, and help a choking victim, and is issued by the American Heart Association after you pass a course and exam.
  • The credential is valid for two years and must be renewed before it expires if your job requires it.
  • Healthcare workers, first responders, and many other professions are required by law or employer policy to hold current BLS certification.
  • You can take BLS training in person at a hospital, training center, or community college, or online through an AHA-authorized provider.

Who Needs BLS Certification

Healthcare workers are the largest group required to hold BLS. Nurses, physicians, paramedics, dentists, and respiratory therapists must maintain current certification as a condition of employment and licensure. Many hospitals will not hire someone without it, and some require renewal every year instead of every two years.

First responders—firefighters, police officers, and emergency medical technicians—also need BLS. Beyond those roles, childcare workers, school staff, fitness trainers, and security personnel often face employer requirements to hold the card. Some states mandate it for certain positions; others leave it to the employer's discretion. If you are unsure whether your job requires it, ask your supervisor or check your employee handbook.

How to Get BLS Certification

The American Heart Association offers BLS training through authorized training centers. You can find a course near you on the AHA website by entering your zip code. Most hospitals, community colleges, fire departments, and private training companies are authorized to teach and test BLS.

In-person courses are the most common option. You attend a class, usually four to six hours long, where an instructor teaches CPR technique, AED use, and choking relief. You practice on a mannequin and take a written test and skills test before you receive your card. Some providers offer blended courses where you watch videos at home and attend a shorter in-person session for the hands-on portion.

Online-only BLS certification does not exist from the American Heart Association, because the skills test requires an instructor to watch you perform CPR on a mannequin. However, some authorized providers offer online classroom instruction followed by a brief in-person skills check, which can save time if you live far from a training center.

Cost and Timing

BLS certification courses typically cost between $50 and $150, depending on the provider and location. Hospital-based courses are sometimes free or discounted for employees. Community colleges and fire departments often charge less than private training companies. Some employers cover the cost as a job requirement.

Most training centers can schedule you within one to two weeks. If you need certification urgently, call ahead to ask about same-day or next-day courses, which some centers offer. Once you pass, you receive your card when ready or within a few days. The entire process from enrollment to card in hand usually takes less than a month.

Renewal and Expiration

Your BLS card expires two years from the date you pass the course. If your job requires certification, you must renew before the expiration date. Some employers give you a grace period of a few weeks; others will not let you work until you have renewed. Check with your supervisor about your workplace's policy.

Renewal courses are shorter than initial certification, usually one to two hours, because you already know the material. You still take a written test and skills test. Some providers offer renewal-only courses at a lower price than initial certification. If your card has already expired, you must take the full initial course again; you cannot renew an expired card.

What BLS Does Not Cover

BLS certification teaches emergency response for cardiac arrest and choking, but it does not cover other medical emergencies. First aid certification, which is separate, covers wounds, burns, shock, and other injuries. Some employers require both BLS and first aid; others require only BLS. If your job involves working with children, pediatric BLS (PALS) is sometimes required instead of or in addition to standard BLS.

BLS also does not make you a medical professional or give you the authority to diagnose illness. It teaches you to recognize when someone is unresponsive and not breathing normally, and to start CPR and use an AED. The goal is to keep blood flowing to the brain and heart until emergency responders arrive.

Where to Find Training Centers

The American Heart Association website has a course locator tool where you enter your zip code and see all authorized training centers near you. You can filter by course type, date, and whether you want in-person or blended training. Most centers let you register and pay online.

If you cannot find a course nearby, call your local hospital, fire department, or community college. Many offer BLS training to the public. Your employer may also have a preferred training center or may offer courses on-site. Some large companies train their own staff and issue AHA cards through an internal instructor.

Frequently Asked Questions

Can I take BLS online?

The American Heart Association does not offer fully online BLS certification because you must demonstrate CPR skills in front of an instructor. Some authorized providers offer blended courses with online classroom work and a short in-person skills session. You cannot pass the skills test without being physically present.

What happens if my BLS card expires?

If your card expires and your job requires BLS, you cannot work in that role until you renew. You must take the full initial course again; expired cards cannot be renewed. Some employers give a short grace period, but most require current certification as a condition of employment.

Is BLS the same as CPR certification?

No. CPR certification covers chest compressions and rescue breathing only. BLS adds AED use and choking relief. Many jobs that require CPR actually require BLS. Check your job posting or employee handbook to see which one your employer needs.

How long does BLS certification take?

Initial BLS certification usually takes four to six hours of class time. Renewal courses are shorter, typically one to two hours. From the day you register to the day you receive your card, the process usually takes one to three weeks, depending on how quickly you can schedule a course.

Do I need BLS if I work in an office?

Most office jobs do not require BLS. However, some employers require all staff to hold it as a safety measure, or certain roles within the office may need it. Check your job description or ask your supervisor whether your position requires BLS certification.
