If you're preparing for the PALS exam, you probably want to know what you're up against. How many people pass? What score do you actually need? And most importantly, how can you make sure you're one of the people who passes on the first attempt?
Here's the good news: the PALS pass rate is higher than you might think. But there are some critical things you need to know about the exam format, scoring, and preparation that can make the difference between passing and retesting.
What Is the PALS Pass Rate?
The AHA does not publicly release official pass/fail statistics for PALS. However, based on data from major training centers and course providers, the estimated first-attempt pass rate for PALS is between 80% and 90%. That means the large majority of test-takers pass on their first try.
For healthcare professionals who study systematically using practice questions and algorithm review, pass rates are even higher. The people who fail tend to share a few common patterns — which we'll cover below.
What Score Do You Need to Pass PALS?
The PALS written exam requires a minimum score of 84% to pass. For the standard 50-question exam, that means you need to answer at least 42 out of 50 questions correctly. You can miss up to 8 questions and still pass.
Quick Math
- 50 questions total
- 84% passing threshold = 42 correct answers
- You can miss up to 8 questions
- Time limit: 90 minutes (about 1 min 48 sec per question)
The 84% threshold is higher than many certification exams, which is why focused preparation is essential. You don't have much room for guessing — you need to genuinely know the material.
What Topics Are Most Heavily Tested?
The PALS exam draws from 8 content areas defined by the American Heart Association. Understanding which areas are weighted most heavily can help you prioritize your study time:
- 1.Systematic Approach to the Seriously Ill Child — The pediatric assessment triangle, primary assessment (ABCDE), and recognizing respiratory vs. circulatory emergencies.
- 2.Recognition and Management of Cardiac Arrest — Shockable vs. non-shockable rhythms, CPR quality, defibrillation.
- 3.Bradycardia and Tachycardia Algorithms — When to give atropine vs. epinephrine, cardioversion thresholds, vagal maneuvers.
- 4.Shock Recognition and Management — Hypovolemic, distributive, cardiogenic, and obstructive shock types and their fluid/medication protocols.
- 5.Pharmacology — Epinephrine, amiodarone, adenosine, atropine doses and indications.
Why Do Some People Fail PALS?
Based on feedback from training centers and course instructors, the most common reasons for PALS exam failure include:
- Not memorizing the algorithms. The PALS algorithms are the backbone of the exam. If you can't walk through the cardiac arrest, bradycardia, and tachycardia algorithms from memory, you're at a significant disadvantage.
- Confusing pediatric and adult protocols. If you hold ACLS too, be careful not to mix up drug doses or energy levels. Pediatric dosing is weight-based, and defibrillation energy differs from adults.
- Rushing through questions. With 90 minutes for 50 questions, you have nearly 2 minutes per question. Read each stem carefully — the exam is designed to test critical thinking, not speed.
- Not using practice exams. Studying content is different from testing your knowledge under exam-like conditions. Practice exams reveal your weak areas before the real test does.
How to Maximize Your Chances of Passing
The healthcare professionals who pass PALS consistently on the first try tend to follow a similar study pattern:
- Start 2–3 weeks before your exam. PALS is not a cram-the-night-before kind of test. Spaced repetition over 2–3 weeks produces significantly better retention.
- Master the algorithms first. Be able to draw out each algorithm from memory. This is the single highest-yield study activity.
- Do 200+ practice questions. Research shows that active recall (answering questions) is far more effective than passive re-reading.
- Take at least 2 timed practice exams. Simulate real exam conditions — 50 questions, 90 minutes, no notes.
- Focus on your weak areas. After each practice session, review the questions you got wrong and understand why.
What Happens If You Don't Pass?
If you don't pass the PALS written exam on the first attempt, you will typically get a second attempt during the same course. The retake uses a different version of the exam. If you fail the second attempt, you'll need to retake the full PALS course before testing again.
This is another reason why preparation matters — failing costs both time and money, since you'll need to pay for the course again.
Bottom Line
The PALS exam is very passable for anyone who prepares properly. With an 84% passing threshold and an estimated 80–90% first-attempt pass rate, the odds are in your favor — as long as you put in the study time. Focus on algorithms, practice with realistic questions, and take timed mock exams. Do those three things and you'll almost certainly walk out with your certification.
