How Often Do You Need BLS Recertification?

Two years, ending on the last day of the month

An AHA BLS card issued in March 2026 is good through March 31, 2028 — not March 14 or whatever day you sat the class. That gives you a few extra weeks, and it means your renewal deadline is always a clean month boundary.

Check your eCard for the exact date rather than counting forward from memory. If you cannot find it, the AHA eCard portal will look it up with your email address.

Who needs BLS rather than Heartsaver

BLS is the provider-level course. It is built for people who respond to emergencies as part of their job:

• Nurses, medical assistants and clinic staff
• Dental offices and oral surgery teams
• EMTs, paramedics and first responders
• Nursing, medical, dental and allied health students
• Lifeguards and some fitness professionals

If you are a teacher, parent, office manager or childcare provider, you almost certainly need Heartsaver CPR & AED instead. Employers occasionally ask for BLS when Heartsaver would do — worth confirming before you pay for the higher-level course.

What a renewal class actually covers

A BLS renewal is not a shortened, watered-down version. It covers the same competencies as the initial course, because the skills that decay fastest are the ones that matter most:

• High-quality compressions — rate, depth, recoil and minimising interruptions
• Adult, child and infant CPR
• Bag-mask ventilation, including two-rescuer technique
• AED use, including special situations
• Team dynamics and role assignment during a resuscitation
• Choking relief for responsive and unresponsive victims

You finish with a skills test on a manikin and a written exam. Compression quality is measured, not eyeballed.

What happens if your card expires

There is no grace period. An expired card is an expired card, and most employers treat it as a compliance failure the day it lapses — which in a hospital or clinic can mean being pulled off the schedule.

The practical fix is simple: book your renewal 60 to 90 days before the expiration date. That leaves room if a class fills up or your shift changes, and the AHA does not shorten your new card for renewing early.

Classroom or blended?

Both produce the same two-year AHA card. The difference is where the cognitive portion happens:

• Classroom — everything happens in the room. No prep. Better if you learn by doing and would rather block one session than manage homework.
• Blended — you complete the online module first, then come in for a shorter hands-on skills session. Better for shift workers who cannot give up a long block.

What is not equivalent is an online-only "certification" with no in-person skills check. Those are not AHA cards, and hospital credentialing offices reject them routinely. If a course never puts your hands on a manikin, assume your employer will not accept it.

A note for employers

If you manage a clinical team, the cheapest version of this problem is the one you prevent. Run renewals as a group on site, stagger them so the whole department does not expire in the same month, and keep a single tracker with every card's expiry. On-site group training removes the travel time entirely.

Bottom line

Two years, expiring at the end of the month printed on your card. Book the renewal 60 to 90 days out, make sure the course includes a real hands-on skills check, and confirm whether your employer actually requires BLS or whether Heartsaver covers you.
