Imagine this: your manager asks you to update your credentials, or you’re applying for a new job. You check your wallet and notice your BLS card expired last month. Do you take the full initial course again, or just the shorter recertification? Knowing the differences helps you choose the right class and stay prepared to save lives.

This guide breaks down the key differences between BLS initial and recertification courses, including who should take them, what’s covered, duration, and cost.

What is BLS Certification?

Before we compare the classes, let us define the subject. BLS stands for Basic Life Support. Healthcare providers use these skills to save lives. It involves more than just CPR (Cardiopulmonary Resuscitation). BLS covers rescue breathing, how to use an automated external defibrillator (AED), and how to help someone who is choking.

Doctors, nurses, dentists, and emergency medical technicians need this certification. Many hospital jobs require it. The American Heart Association (AHA) creates the guidelines for these courses. They set the standard for what students must learn.

The Initial BLS Course Explained

The initial BLS course is for people who have never taken BLS before. It is also for people whose certification has expired for a long time. Think of this class as the foundation. You start from zero and build your skills up.

1. Who Should Take This Class?

The initial BLS certification course is prepared for those starting a career in healthcare or emergency response, as well as for anyone who has never received BLS training. It is also required for individuals whose certification has expired and requires full renewal. This hands-on course provides practical experience with manikins and equipment, ensuring participants are well-prepared to handle real-life emergencies.

2. Course Content & Requirements

The initial BLS course teaches essential life-saving skills, such as:

  • CPR for adults, children, and infants.
  • Use of an Automated External Defibrillator (AED).
  • Choking relief techniques (Heimlich maneuver).
  • Basic airway management.
  • Identifying and responding to cardiac arrest.

3. Course Duration

The initial BLS course typically takes 3-4 hours, depending on class size and the pace of instruction. Upon completion, participants are required to complete both the online theory session and a skills evaluation to earn their certification. The skills test assesses the ability to perform CPR and other life-saving procedures, while the theory verifies understanding of essential BLS concepts.

The BLS Recertification Course Explained

The recertification course goes by many names. You might see it called a renewal class or a BLS update. The goal is different here. This class is not for learning from scratch. It is for polishing skills you already possess.

1. Who Should Take This Class?

Recertification is necessary for individuals whose initial BLS certification has expired or is nearing expiration. Since most BLS certifications are valid for two years, staying current with skills and techniques is essential. Maintaining an up-to-date certification is crucial for those working in healthcare and emergency response, as many employers require it.

2. Course Content & Requirements

Although recertification includes much of the same material as the initial course, it is shorter and emphasizes refreshing existing skills rather than learning them for the first time. Participants review key life-saving techniques and practice them before completing the skills test.

3. Course Duration

Recertification courses last 1-2 hours, shorter than the initial certification. The recertification process is streamlined, but participants still need to demonstrate proficiency in CPR, AED use, and other critical skills. After completing the online course, participants take a skills test to receive their renewed certification.
