What You Need to Do to Teach First Aid and CPR

To become a first aid and CPR instructor, you must complete a training course through an organization like the American Red Cross or American Heart Association, pass a written exam and practical skills test, and then register with that organization. Most programs require you to be at least 15 or 16 years old and hold a current CPR certification yourself before you enroll in instructor training. The entire process—from your first class to your instructor card—typically takes 2 to 4 weeks, though some accelerated courses compress it into a single weekend.

Unlike many certifications, there is no single national licensing body that oversees all first aid and CPR instructors. Instead, the major training organizations (American Red Cross, American Heart Association, and a few smaller bodies) each certify their own instructors. Your instructor card will be valid only for courses taught under that organization's name and curriculum. If you want to teach for multiple organizations, you will need separate certifications from each one.

Key Takeaways

  • You must hold a current CPR certification and complete an instructor-level course through American Red Cross, American Heart Association, or another recognized training organization.
  • Instructor courses include classroom time, a written exam, and a practical demonstration where you teach a short lesson to evaluators.
  • Your instructor certification lasts 2 years for most organizations, after which you must renew through a recertification course or exam.
  • Instructor cards are organization-specific—a Red Cross instructor card does not let you teach American Heart Association courses without separate training.
  • Many employers (schools, workplaces, gyms) prefer or require instructors to hold certifications from the major national organizations rather than smaller regional bodies.

Get Your Own CPR Certification First

Before you can teach CPR, you must hold a current CPR card yourself. This is a hard requirement—no organization will admit you to instructor training without proof. If you do not already have one, take a standard CPR course through your chosen organization (American Red Cross or American Heart Association). These courses run 3 to 4 hours and cost between $50 and $100. You will learn chest compressions, rescue breathing, and how to use an automated external defibrillator (AED).

Your CPR card is valid for 2 years. If your card has expired, you must renew it before enrolling in instructor training. Some organizations offer a "renewal" course that is shorter and cheaper than the full course if you have held a card before. Check the expiration date on your card now—if you are within 6 months of expiration, renew before you start instructor training, because the training organization will check the date on your first day of class.

Choose Your Training Organization and Enroll

The two largest organizations are the American Red Cross and the American Heart Association. Both offer instructor courses in most U.S. states, though availability varies by region. The Red Cross tends to have more locations and flexible scheduling; the American Heart Association is often preferred by hospitals and medical settings. Smaller organizations like the National Safety Council also certify instructors, but employers are less familiar with their credentials.

Search the organization's website for "instructor course" or "instructor training" in your state. You will see a list of upcoming classes, locations, and dates. Most courses run 2 to 3 days in a row, though some organizations offer weekend-only or evening options. Enroll directly through the organization's website or by calling the local training center. Expect to pay $200 to $400 for the instructor course itself, plus any materials or exam fees. Some employers (hospitals, schools, fire departments) subsidize or cover the cost if you agree to teach for them.

Complete the Instructor Course and Pass the Exam

The instructor course teaches you how to run a first aid or CPR class, not just how to perform CPR yourself. You will learn how to set up a classroom, manage a group of students, use training manikins (practice dummies), answer common questions, and handle students who struggle with the material. The course also covers the organization's policies on student records, certification cards, and what to do if a student fails the exam.

On the last day, you will take a written exam (usually 50 to 75 multiple-choice questions) and a practical test. The practical test requires you to teach a short lesson—typically 5 to 10 minutes—on a topic like CPR or choking relief. You will teach to the course instructor and sometimes to other students in the class. The evaluator watches for clear explanations, correct technique, and the ability to answer questions. You must pass both the written exam and the practical demonstration to earn your instructor card. Most people pass on their first attempt if they attend all class sessions and study the materials.

Register and Receive Your Instructor Card

After you pass the exam, the training organization will process your paperwork and issue your instructor card. This usually takes 1 to 2 weeks. Your card shows your name, the organization's logo, the type of instruction you are certified for (CPR only, first aid only, or both), and the expiration date. Keep this card with you when you teach—employers and students will ask to see it.

Your card is valid for 2 years. Before it expires, you must renew your certification. Renewal typically involves taking a shorter recertification course (1 to 2 hours) or passing a written exam without the full classroom training. Some organizations allow you to renew online. Plan ahead—do not wait until your card expires to renew, because you cannot teach with an expired card and the renewal process takes time.

Understand What You Can and Cannot Teach

Your instructor certification covers only the courses and skills you trained for. If you complete Red Cross CPR instructor training, you can teach Red Cross CPR courses. You cannot teach American Heart Association CPR courses, first aid courses from other organizations, or advanced life support (ALS) courses without separate training. Each course type and each organization requires its own instructor certification.

Most instructors start with CPR-only certification, which is the fastest and cheapest route. First aid instructor training is a separate course that covers wounds, burns, choking, shock, and other non-cardiac emergencies. Some organizations offer a combined "CPR and First Aid" instructor course that covers both in one training. Check what your employer or intended students need before you enroll—if you plan to teach in a school, ask whether they want CPR only or CPR plus first aid.

Find Teaching Opportunities and Build Your Schedule

Once you have your instructor card, you can teach classes through your organization's training centers, or you can approach employers directly. Schools, workplaces, gyms, swimming pools, and childcare centers all need instructors to train their staff and members. Some instructors work full-time for a training center; others teach part-time while holding another job. Pay ranges from $20 to $50 per hour depending on your location, the organization, and whether you are teaching a public class or a private corporate session.

To find teaching work, contact your local training center and ask if they hire instructors. Many centers maintain a list of certified instructors and call them when classes are scheduled. You can also reach out directly to employers in your area—call the HR department or safety manager and ask if they need an instructor. Some instructors build a private practice by marketing themselves to local businesses and offering on-site training. Start by teaching a few public classes through your training center to build experience and confidence before you pursue private clients.

Frequently Asked Questions

Do I need a high school diploma or college degree to become a CPR instructor?

No. Most organizations require only that you be at least 15 or 16 years old and hold a current CPR card. Education level is not a requirement. However, you must be able to read, write, and speak clearly enough to teach a class and pass a written exam.

Can I teach CPR if I am certified by one organization but my employer uses another?

No. Your instructor card is specific to the organization that issued it. If your employer uses American Heart Association courses, you must hold an American Heart Association instructor card. You would need to complete a separate instructor course with that organization.

What happens if a student fails the CPR exam in my class?

Students who fail can retake the exam, usually when ready or within a few days. You cannot issue a card to someone who has not passed. The organization's policy will tell you how many retakes are allowed and whether there is an extra fee. Document the failure in your student records.

How much does it cost to become a CPR instructor from start to finish?

If you already have a CPR card, expect to spend $200 to $400 on the instructor course itself, plus any exam or material fees. If you need to get your CPR card first, add another $50 to $100. Some employers cover these costs if you commit to teaching for them.

Can I teach CPR online or do I have to teach in person?

Most CPR and first aid instruction must happen in person because students need to practice chest compressions and other hands-on skills on a manikin. Some organizations now offer blended courses where students watch videos online and then come to a classroom for the practical skills session. Ask your training organization what formats they offer.
