The CPR/AED Guide
Everything you need to know before sitting for CPR / AED Certification
Why CPR/AED matters in 2026
CPR / AED Certification is one of the most recognized credentials issued by American Red Cross / AHA, and 2026 hiring data continues to show CPR/AED on job postings as either required or strongly preferred for the roles it targets. The certification validates that you can apply real working knowledge, not just recall facts, across 7 distinct exam domains, with the largest weight on Adult CPR. For candidates competing in the American Red Cross / AHA ecosystem, CPR/AED is a clear signal to a hiring manager that you have invested in measurable, third-party-verified competence.
Who should take CPR/AED
CPR/AED is most useful for professionals working in or moving toward the American Red Cross / AHA ecosystem. In short: Lifesaving cardiac and breathing emergency skills. If you are early in your career, CPR/AED is one of the fastest credentials to add to a résumé that recruiters actively screen for. If you are mid-career, it formalizes the skills you already use day-to-day and unlocks roles that gate on it. If you are switching tracks, it gives you a structured curriculum that tells you exactly what to study, in what order, weighted by what the real exam tests.
Exam structure and difficulty
The CPR / AED Certification exam is organized into 7 domains, each weighted by the official American Red Cross / AHA exam guide. The heaviest weighting is Adult CPR at 22% of the exam, so that is where you should spend the most preparation time. The lightest is Introduction and Chain of Survival at 8%, meaning you can dedicate roughly proportional review time without over-investing.
Format details: Hands-only and full-CPR pathways · AED skill check required · 2-year certification cycle (AHA / ARC). Following the domain weights is the single biggest leverage point candidates miss, because many over-study lower-weighted material that feels comfortable.
How to prepare
A practical four-step plan for CPR/AED:
- Read the official American Red Cross / AHA exam guide for CPR/AED and write down every sub-objective. This becomes your study checklist.
- Use the domain practice quizzes on this page in weight order (heaviest first). Aim for 80% on each domain before moving on.
- When you miss a question, read the explanation for every wrong answer, because that contrastive learning is where understanding compounds.
- Once every domain is at 80%+, take the Mix Quiz repeatedly to simulate real exam conditions across all topics.
Career outcomes and salary
Holders of CPR/AED in the US currently see compensation in the range of $35k to $65k per year, with median around $48k. Required across many roles; not a standalone job Salary varies by region, employer size, and complementary skills, but the CPR/AED credential consistently lifts the floor of what you can negotiate against.

Common pitfalls
The three traps that kill CPR/AED candidates: (1) over-memorizing acronyms instead of practicing the application of concepts in scenarios, when the exam is scenario-driven, not a vocab quiz. (2) Skipping the heaviest-weighted domain because it feels less interesting, which can fail the whole exam by neglecting Adult CPR. (3) Not timing practice sessions, when the exam has a real clock and pacing is its own skill. Build timing into your last two weeks of prep.
CPR/AED questions, answered
Where can I find free CPR test questions and answers?
QuizBuffet’s CPR and AED practice test gives you 300+ free multiple-choice questions with instant answers and explanations, no signup required. Practice one domain at a time (compressions, AED use, choking, and more) or run a mixed session that mirrors the real exam.
Can you do CPR and AED training online?
The knowledge portion can be done online through blended courses like AHA HeartCode, but a hands-on skills check with an instructor is still required to get certified. QuizBuffet’s free practice test covers that knowledge portion so you walk into the skills check ready.
What do you need to know to pass a CPR test?
Focus on the Chain of Survival, correct compression rate and depth for adults, children, and infants, when and how to use an AED, and the choking response. Most CPR/AED written exams require 80% or better, so working through practice questions by domain is the fastest way to find your weak spots before test day.
Which comes first, CPR or AED?
Start CPR immediately, and use the AED the moment it arrives; you do not finish a full round of CPR first. If you are alone, call 911 and get the AED yourself; if others are present, send someone for the AED while you begin compressions right away.
What kind of questions are on the CPR test?
Most CPR/AED exams are multiple choice. They cover the Chain of Survival, how to check responsiveness and breathing, compression rate and depth for adults, children, and infants, how to use an AED, and how to help someone who is choking. QuizBuffet mirrors that exact mix across all seven domains.
How hard is it to get AED certified?
Not very. An AED is designed for untrained bystanders, so the device speaks each step out loud as you go. Most courses pair a short written test with a hands-on skill check, and the written part usually asks for around 80% or better to pass.
Are AED and CPR certification the same thing?
No. CPR is the manual skill of chest compressions and rescue breaths, while an AED is a portable device that reads the heart rhythm and delivers a shock when one is needed. Most certifications teach both together in a single CPR/AED course.
Is it safe to use an AED on a pregnant patient?
Yes. Using an AED on a pregnant woman is safe and recommended, and the shock will not harm the baby. Place the pads in the standard positions and follow the voice prompts the same way you would for any adult.
How many questions are on a CPR/AED exam?
It depends on the provider, but written exams commonly run between 25 and 35 multiple-choice questions. QuizBuffet gives you 300+ practice questions so the real test feels familiar before you sit it.
What score do you need to pass CPR certification?
Most courses set the passing score around 80% on the written exam, plus a successful hands-on skill check. Some are higher; the AHA BLS Provider exam, for example, requires 84%. Check your specific provider for the exact cutoff.
How long does CPR/AED certification last?
For both the American Heart Association and the American Red Cross, CPR/AED certification is valid for two years. After that you renew it with a shorter refresher course.
Can you fail a CPR test?
Yes, but it is uncommon and easy to recover from. If you miss the passing score or a skill step, instructors let you review and retake it. Working through practice questions first is the simplest way to avoid that.
