AED certification is a credential that proves you’ve been trained to use an automated external defibrillator, the portable device that delivers an electric shock to restore a normal heart rhythm during cardiac arrest. The certification is typically bundled with CPR training and issued by organizations like the American Heart Association (AHA) or the American Red Cross after you complete a course and pass a skills evaluation. Most certifications last two years before you need to renew.
What the Course Covers
AED certification courses teach you how to recognize cardiac arrest, perform CPR, and operate a defibrillator on an adult. The AHA’s Heartsaver CPR AED course, one of the most widely recognized options, covers adult CPR and AED use, choking response for adults, children, and infants, and opioid-related emergencies. Some versions add first aid basics, injury and environmental emergencies, and optional modules for child and infant CPR.
The AED-specific portion walks you through powering on the device, placing the electrode pads on the chest, standing clear while the machine analyzes the heart’s rhythm, and pressing the shock button if the device advises it. You also practice integrating AED use with chest compressions, since real-world rescues require switching between the two. All of this is practiced on mannequins in a supervised setting.
Who Needs It
AED certification isn’t federally mandated for most workers. OSHA standards don’t specifically require AED training, though OSHA does encourage workplaces to install defibrillators and has published guidance recommending training programs. That said, many employers require the certification as a condition of hiring, particularly in fitness centers, schools, childcare facilities, construction sites, and offices with designated first aid responders. Some state and local laws go further than federal standards and mandate AED training for specific roles.
The AHA’s Heartsaver courses are explicitly designed for people with little or no medical background who need a course completion card for OSHA compliance or other regulatory requirements. You don’t need any prior training to enroll.
Layperson vs. Healthcare Provider Courses
There are two distinct tiers of certification, and picking the right one depends on your role. The AHA categorizes its Heartsaver courses as “community training,” meant for the general public: gym staff, teachers, office safety teams, parents. These courses focus on the fundamentals of recognizing an emergency and keeping someone alive until paramedics arrive.
Healthcare professionals take a separate track called Basic Life Support (BLS), which covers the same core skills but adds team-based resuscitation techniques, use of bag-mask devices, and a deeper understanding of the protocols used in clinical settings. If your employer asks for “BLS certification,” a Heartsaver card won’t satisfy that requirement, and vice versa. The Red Cross offers a similar split, with its own community-level and healthcare provider courses.
AHA vs. Red Cross Certification
The American Heart Association and the American Red Cross are the two dominant providers, and most employers accept either. The AHA is the organization that publishes the resuscitation science guidelines other groups follow, so its courses are often seen as the gold standard, particularly in healthcare settings. The Red Cross uses those same evidence-based guidelines to build its own curriculum.
A few practical differences separate them. AHA certifications are valid for two years across all course levels. Red Cross certifications also last two years for most courses, though historically some Red Cross cards were valid for only one year. On the testing side, the Red Cross requires a passing score of 80% on its written exam, while the AHA sets the bar at 84%.
Online-Only Courses Won’t Cut It
Dozens of websites sell fully online AED certifications, but these are unlikely to satisfy an employer or meet regulatory standards. OSHA has stated clearly that online training alone does not meet the intent of first aid and CPR requirements. The agency’s reasoning is straightforward: skills like chest compressions and pad placement are physical, and the only way to learn them is by practicing on mannequins with a qualified instructor watching.
Blended learning courses are a legitimate alternative. Both the AHA and Red Cross offer formats where you complete the knowledge portion online at your own pace, then attend a shorter in-person session to demonstrate hands-on skills. This typically takes less time than a fully in-person class while still meeting employer and regulatory requirements.
Cost and Time Commitment
AED certification is relatively inexpensive. Red Cross pricing for a standalone adult CPR/AED course runs around $30, whether you choose fully in-person or blended learning. Adding first aid to the course bumps the price to roughly $38 to $46. BLS certification for healthcare providers is priced around $25 through the Red Cross. These are base prices for course materials, certification cards, and video access; individual training centers sometimes add a facility fee on top.
In-person Heartsaver courses typically take about three to four hours. Blended versions shorten the classroom portion since you’ve already covered the lecture material online. Renewal courses are shorter still, designed for people whose certification is near expiration but hasn’t lapsed.
How To Get Certified
The process is simple. Visit the AHA or Red Cross website, search for a class near your zip code, and register. You can filter by course type (Heartsaver vs. BLS), delivery format (in-person vs. blended), and date. Many community colleges, fire departments, hospitals, and private training companies also host authorized courses.
On class day, you’ll watch instructional videos, practice CPR and AED skills on mannequins, and take a short written or digital exam. If you pass, you receive a certification card. Both the AHA and Red Cross now issue digital certificates that include a unique ID and QR code, letting employers verify your credential instantly. You can also print or download your certificate anytime through your online account. When your two-year window nears its end, you can take an abbreviated renewal course to extend your certification for another two years rather than repeating the full class.
