Basic life support certification is one of the most in-demand credentials in healthcare. Whether you're a nurse, EMT, dental hygienist, or fitness trainer, having a valid BLS card can mean the difference between keeping your job and losing it. About 18,000 people search for basic life support certification every month—and most of them are trying to answer the same handful of questions: How do I get certified? How much does it cost? How long does it last?
This guide answers all of that. We'll walk through the entire process from picking a course to sitting the exam, so you can walk away with your card and get back to work.
BLS certification proves you can perform basic life support techniques—CPR, rescue breathing, and AED use—on adults, children, and infants. It's not the same as a general first aid certificate or a public CPR course. BLS is specifically designed for healthcare providers: people who might encounter a cardiac arrest on the job, not just in a parking lot.
The American Heart Association (AHA) is the gold standard for BLS training. Their AHA BLS certification is recognized by virtually every hospital, clinic, and healthcare employer in the United States. The Red Cross also offers a widely accepted version. When your employer says "BLS required," they almost always mean one of these two.
The short answer: anyone who works in or near a clinical setting. That said, requirements vary by role and state.
You'll almost certainly need current BLS if you're a:
Even some non-clinical roles—school employees, lifeguards, childcare workers—are required to hold BLS in certain states. Check your licensing board's rules if you're not sure.
The AHA offers three delivery formats for its BLS Provider course:
You show up in person, practice on manikins, and get immediate feedback from a certified instructor. This is the traditional route, and it's still the most thorough. Classes typically run 3–4 hours. If you've never had BLS training before, start here.
HeartCode splits the course into two parts: you complete the cognitive portion online (about 1–2 hours), then attend a brief hands-on skills session at an authorized training site. The skills session usually takes 45–60 minutes. Many hospitals and large healthcare systems use this format because it's faster and flexible without skipping the manikin practice.
Here's where people get confused. You cannot complete a fully AHA-compliant BLS certification online. Any course that promises a card without hands-on skills testing isn't a real AHA course—and many employers won't accept it. If someone's offering a 0 online-only BLS card, walk away.
The AHA BLS Provider course covers:
The skills evaluation is practical—an instructor watches you perform CPR and other skills on a manikin and checks that you meet minimum competency standards. There's also a written or digital exam, typically 25 questions, covering core concepts. You need to pass both parts to earn your card.
Understanding the bls chain of survival is crucial for the exam. The AHA's chain of survival lays out the sequence of actions that maximize survival after cardiac arrest: early recognition, early CPR, early defibrillation, advanced care, and recovery.
Expect to pay 0–00 for a BLS provider course. Here's roughly what drives the price:
Don't pay extra for expedited processing or fancy laminated cards—the AHA eCard (digital certification) is valid and widely accepted. You can verify it instantly online.
Your BLS card is valid for two years. After that, you need to renew—even if you know the material cold.
Many healthcare workers get caught off guard when their card expires right before a license renewal or hospital credentialing check. Set a calendar reminder 3 months before your expiration date. That gives you plenty of time to find a bls renewal course without scrambling.
The renewal process is nearly identical to initial certification—you take the course again and demonstrate your skills. There's no shortcut for letting your card lapse; if it's expired, you retake the full course.
Some providers offer a renewal-specific class that's slightly shorter, since you're assumed to have prior experience. These typically run 2–3 hours for classroom format. HeartCode BLS Renewal is also available for the blended path.
BLS recertification should be on your radar if:
Most people pass the BLS written test without much trouble—but it's not completely trivial. The questions cover CPR ratios, compression depth, AED operation, and scenarios where you have to identify the right action. Here are the key numbers to memorize:
Running through practice questions before your class helps you feel more confident during the skills portion too, because you've already thought through the scenarios. Our American Heart Association BLS practice resources include hundreds of questions modeled on real exam content.
Once you have your card, list it clearly. The standard format:
BLS Provider — American Heart Association, Expires [Month Year]
Include it in a Certifications or Licenses & Certifications section, not buried in your skills list. Recruiters and HR teams scan for it specifically, and it needs to be findable. Don't abbreviate it as just "CPR"—employers looking for BLS won't equate the two.
If your employer verifies credentials through a platform like symplr or Greenway Health, make sure your card number is entered correctly. The AHA's verification portal (using your eCard code) is where they'll check.
The AHA's course finder at heart.org lets you search by zip code for authorized training centers. Filter by BLS Provider and your preferred format. Results show price, availability, and whether group bookings are accepted.
A few other places to check:
If you're in a rural area or have a packed schedule, HeartCode BLS gives you the most flexibility. You do the online portion whenever you want, then find any authorized skills station for a 45-minute slot.
Buying an online-only card. Some sites sell certificates that look official but aren't recognized by hospitals or licensing boards. Always verify that a course is run by an AHA-authorized training center before you pay.
Letting your card expire before renewal. An expired card is the same as no card in most employers' eyes. Don't wait until the month it expires—renewal slots fill up fast, especially in January and September when clinical programs start.
Confusing BLS with ACLS or PALS. Advanced Cardiovascular Life Support (ACLS) and Pediatric Advanced Life Support (PALS) are higher-level credentials for specific clinical roles. BLS is the prerequisite for both. Get BLS first, then layer on ACLS or PALS if your role requires it.
Not practicing compression technique before class. The skills evaluation tests compression depth, rate, and recoil. Going in cold can mean failing the practical even if you ace the written portion. Watch a couple of AHA tutorial videos beforehand—it helps more than you'd think.
It's worth being specific about what BLS certification is and isn't. Here's how it stacks up against other CPR courses:
Community or Heartsaver CPR/AED courses are designed for laypeople—bystanders who might respond to an emergency in a public setting. They're shorter, often fully online, and don't require skills testing by a credentialed instructor in the same way.
BLS for Healthcare Providers is a more rigorous standard. It covers additional scenarios (two-rescuer CPR, infant CPR, bag-mask ventilation), requires instructor observation, and results in a card that healthcare employers actually accept. If a job posting says "BLS required," they mean this version—not a Heartsaver card.
When in doubt, call your employer's credentialing or HR department and ask which specific certification they accept. Five minutes on the phone saves you from taking the wrong course.
CPR certification is a broad term that can refer to any course teaching cardiopulmonary resuscitation—including public-facing courses that don't require hands-on testing. BLS certification is specifically for healthcare providers and requires demonstrating skills on a manikin in front of a certified instructor, plus passing a written exam. Most healthcare employers require BLS, not just a general CPR card.
No. An AHA-compliant BLS certification requires a hands-on skills evaluation with an instructor. The HeartCode BLS format lets you complete the cognitive portion online, but you must attend an in-person skills session to earn your card. Any course offering a certificate with zero in-person component isn't recognized by AHA-affiliated employers.
A traditional classroom BLS course takes 3–4 hours from start to finish. With HeartCode blended learning, you'd spend about 1–2 hours online and then 45–60 minutes at a skills station—under 3 hours total, though spread across two sittings. Your eCard or physical card is usually issued same-day or within a few business days.
BLS certification expires every two years. You'll need to complete a renewal course before the expiration date—an expired card isn't valid. Most providers recommend scheduling your renewal 60–90 days before expiration to avoid any gap in coverage.
AHA BLS is the most universally accepted format in the U.S. and many other countries. American Red Cross BLS is also widely accepted. If you're working internationally or with a non-U.S. employer, check which body they recognize. Always confirm with your employer before taking a course.
If your card has expired, you can't take a shorter renewal course—you must complete the full BLS Provider course from the start. There's no grace period. Many employers will require recertification before your next shift if your card has lapsed, so it's worth staying ahead of the expiration date.
The AHA requires a score of 84% or higher on the written portion—at least 21 out of 25 questions correct. You must also pass the skills evaluation. If you fail either part, you'll typically have an opportunity to remediate and retest during the same session or schedule a makeup.
Basic life support certification isn't complicated—but it does require showing up and doing the work. Pick an authorized course, practice your compression technique, and review the key numbers before class. Two to four hours later, you'll have a credential that most healthcare jobs require and that stays valid for two years.
If you want a head start on the written exam, practice tests are one of the best ways to identify gaps in your knowledge before you're sitting in a classroom. Our BLS practice questions cover the same topics as the AHA exam—CPR ratios, AED protocols, team dynamics, and multi-rescuer scenarios—so you walk in knowing what to expect.
Don't wait until your employer sends a reminder that your card is expiring. Find a bls certification classes option that fits your schedule, lock in your renewal date, and keep your credentials current.
