How Long is ACLS Class?

Every year, more than 300,000 people in the U.S. suffer a cardiac arrest outside of a hospital, and nearly 90% of those cases are fatal. With each passing minute, survival chances drop – unless someone trained to help can intervene. That’s why Advanced Cardiovascular Life Support (ACLS) training is so essential for healthcare professionals

If you’re considering certification, one of the first questions you’ll likely ask is: How long is the ACLS class? The answer depends on your experience level and the format you choose. For first-time certification, the course typically takes 6 to 10 hours. If you’re just getting recertified, it usually takes 4 to 6. Online ACLS courses offer even more flexibility, with experienced providers often completing the training in just a few focused hours.

The ACLS course structure typically covers critical skills like BLS, airway management, rhythm recognition, and medication use, all based on current ILCOR guidelines. Course duration depends on factors like your clinical experience, whether you take the class online or in person, and how efficiently you study.

Standard ACLS Course Duration

How Long Is the Initial ACLS Certification Course?

The initial ACLS course typically takes 6 to 10 hours. Factors such as class size, pace, and the level of skills practice involved can sometimes push this closer to 12 hours. All formats follow a structured curriculum and result in a valid ACLS provider card, which is good for two years.

How Long Does ACLS Recertification Take?

If you’re renewing your ACLS certification, the recertification classes typically take about 4 to 6 hours, especially for experienced practitioners who regularly apply these skills. This course still covers the core components of advanced cardiac care but focuses more on updates, protocol changes, and practical application. Since resuscitation guidelines are updated regularly, recertifying every two years ensures that your training aligns with the most current standards in emergency cardiovascular care.

Online vs. In-Person ACLS Class Time Requirements

Traditional in-person ACLS classes tend to require a full day or more when you factor in travel, fixed schedules, and group instruction. 

In contrast, online ACLS courses are designed to be self-paced and flexible. If you already have a solid understanding of ACLS principles, you can complete an online ACLS class in one day or less. Many online providers also offer unlimited access to study materials, downloadable handbooks, and immediate proof of certification.

ACLS Course Breakdown: What to Expect

• Classroom Instruction Time: Typically takes 4 to 6 hours and covers essential ACLS topics, including BLS review, ECG interpretation, airway management, and medication use.
• Skills Practice and Simulations: Usually takes 1 to 2 hours, depending on class size, and involves applying protocols in real-world scenarios to reinforce decision-making and team communication.
• ACLS Megacode Testing Duration: This final skills assessment lasts about 15 to 20 minutes, evaluating your ability to manage a full cardiac emergency from start to finish.
• Written Exam Length and Passing Requirements: Takes about 30 to 45 minutes to complete a 40- to 50-question exam. A passing score of 84% or higher is typically required.

How to Complete ACLS Certification Faster

You can complete ACLS in a single day, especially if you choose to take it online. Though there’s no formal “fast-track” course, self-paced online programs allow you to move quickly if you’re confident in the material. Experienced practitioners can complete the training and exam and receive certification in just a few hours.

Clinical background also plays a role. If you’re already comfortable with ACLS principles, you can move through the content quickly. Newer learners may need more time to review algorithms and study key skills.
