BLS certification requires passing a 25-question written exam at 84% (21/25) plus hands-on skills testing. ACLS requires BLS prerequisite, a written exam (50 questions, 70% passing), and scenario-based megacode skills evaluation. Both certifications are valid for 2 years. BLS costs $30–$75; ACLS costs $150–$290. The AHA 2020–2025 guidelines are current, with a 2023 update broadening TTM targets to 32–37.5°C.
About the BLS / ACLS Exam
The AHA BLS and ACLS certifications are the gold standard for healthcare providers. BLS covers CPR for adults, children, and infants; AED use; and 2-rescuer CPR. ACLS builds on BLS with cardiac arrest algorithms (VF/pVT, PEA/asystole), arrhythmia management, pharmacology, stroke, ACS, and special resuscitation situations.

Frequently Asked Questions
What is the BLS passing score?
The AHA BLS written exam requires a passing score of 84%, which means getting at least 21 out of 25 questions correct. In addition to the written exam, you must demonstrate hands-on CPR skills including correct compression rate (100–120/min), depth (2–2.4 inches), full chest recoil, and AED operation.
How many questions are on the ACLS exam?
The AHA ACLS written exam contains 50 questions with a 70% passing requirement (35/50). The exam covers cardiac arrest algorithms, arrhythmia interpretation, pharmacology, and systematic patient assessment. You also must pass a skills evaluation including a megacode scenario.
How long is BLS/ACLS certification valid?
Both BLS and ACLS certifications are valid for 2 years from the date of successful completion. Renewal courses are shorter (4–6 hours for BLS, 8–10 hours for ACLS) compared to initial certification courses.
Do I need BLS before taking ACLS?
Yes. AHA ACLS requires current BLS certification as a prerequisite. You must demonstrate BLS-level CPR proficiency before enrolling in ACLS. Some training centers offer BLS + ACLS combination courses completed in 1–2 days.
What are the AHA 2023 TTM updates?
The 2023 AHA targeted temperature management update broadened the TTM target range to 32–37.5°C for at least 24 hours in comatose post-cardiac arrest patients. After TTM, fever (>37.5°C) should be prevented for at least 72 hours post-ROSC.
What is the compression rate for adult CPR?
The AHA 2020 guidelines specify 100–120 compressions per minute for adult CPR. Depth should be at least 2 inches (5 cm) but no more than 2.4 inches (6 cm). Allow complete chest recoil between compressions and minimize pauses to <10 seconds.
