What is the Precision Nutrition Certification?

A deep understanding of nutrition, the authority to coach it, and the ability to turn what you know into results.

The PN Level 1 Certification will teach you all that, including the methodology we’ve tested, refined, and proven with over 100,000 coaching clients.

Imagine if you had all the nutrition, coaching, and change psychology research… all the scientific concepts… all the experience… all the practical “how-to” stuff… all in one place.

If you had a trusted source of education… a proven system… and real-life advice to help guide your professional development.

If it came in a clear, understandable, self-paced learning format that suited your schedule.

And if, at the end of the process, you had a system (like ProCoach) to deliver the habit-based nutrition coaching you just learned, so you can grow a practice while working less and getting better results.

That’s what The Precision Nutrition Level 1 Certification is here for.

In addition to learning how nutrition really works, you’ll understand how people think and act, and you’ll be able to turn that into a thriving coaching practice.

This means you’ll get better results, attract more clients and patients, keep them for longer, and make more money than you thought possible.

Whether you’re:

  • just starting out in the field of health, fitness, or wellness;
  • an established professional in the middle of your career;
  • passionate about health and considering a career change;
  • working with people one-on-one or in a group setting; or
  • wanting to deepen your knowledge of nutrition…

… you can become Precision Nutrition Certified.

Fast Company rated Precision Nutrition one of the
most innovative companies in health and fitness.

The principles behind Precision Nutrition are the same type of advice Dr. John Berardi has been sharing with Olympians and professional athletes. What’s different is that now anyone can work with Berardi and his team of coaches for less than it costs to join a CrossFit gym.

The experts that other
experts come to for help.

Developed by John Berardi, PhD, CSCS and co-written with Ryan Andrews, MS, RD, Brian St. Pierre, MS, RD, Krista Scott-Dixon, PhD, Helen Kollias, PhD, CSCS, and Camille DePutter, the Level 1 Certification is the synthesis of everything we’ve learned over 15 years of coaching and research in nutrition.

Precision Nutrition advises organizations around the world, coaches elite athletes & sports teams, and has been featured in leading publications. There’s a reason over 2 million people come to our website for advice every single month.

“John Berardi is one of the top sports nutrition experts in the world. He concentrates on simple solutions that actually work. That’s why he’s a key part of our high-performance team.”

Paul Winsper

Hayley Wickenheiser

“I have known JB for almost two decades. He has been – and continues to be – my ‘go-to guy’ for all things nutrition and change psychology; he has what all great teachers have: an ability to take complicated constructs, and communicate them in a way that makes sense to simple people like me.”

Stuart McMillan

Thanks, John, for making me bigger and stronger. You are the best thing that I’ve added to my training regimen.”

Unlike most other certifications, this isn’t a program full of abstract theory that doesn’t work in the real world. (Nor is it a program full of internet level, keyboard jockey type information.)

Instead, it’s deep knowledge that’s client-tested, scientifically proven, and constantly updated based on the data we’ve collected working directly with over 100,000 coaching clients and patients.

That’s right, Precision Nutrition is the only nutrition certification company in the world that successfully coaches real clients every day.

Frequently Asked Questions

Here are sample topics from Unit 1:

  • How and why your cells work the way they do
  • How carbohydrates, fats, vitamins, minerals, and other nutrients interact with your cells
  • How food becomes energy for maintenance functions, physical work, and repair
  • How your body balances out the food you eat with the work it does
  • How exercise affects nutritional needs and how nutrition affects exercise

Here are sample topics from Unit 2:

  • What it means to be a good coach
  • How to prepare for clients or patients
  • How to interact with different clients or patients
  • How to assess clients or patients
  • How to know which approaches are best for which clients / patients
  • How to meet people where they are (not where you want them to be)
  • How to keep people progressing from day one until they reach their goals
Who is the PN Level 1 Certification for?

It’s for any health, fitness, or wellness professional (or anyone who’s thinking of joining the field) who wants to feel confident in their ability to successfully coach nutrition and get better results for the people they work with.

We’ve worked with over 50,000 students from every corner of this industry — from personal training and yoga to functional medicine, holistic wellness coaching, and beyond.

Whether you’re already mid-career or just starting out, this certification will give you the knowledge, systems, and tools to make a real, lasting change with anyone you work with.

I have a busy life. How long does it take to get certified?

The PN Level 1 Certification is entirely self-paced, so there’s no deadline. You can take as much time or as little time as you like.

If you’d like some guidelines, however, the pace that seems to work best for most of our students is completing one chapter per week. That means reading the chapter, reviewing the online video, answering the workbook questions, reviewing the FAQ, and writing the 10-question exam.

If you follow that structure, you can expect to spend 3-5 hours per week on the certification materials. Since there are 18 total chapters, you’d earn your Pn1 credentials in a little over four months. Although you can move more quickly or slowly depending on your situation.

What are the exams like?

There are 18 short exams with 10 questions each. Questions are either multiple choice or true or false.

The exams are delivered online; they can be accessed whenever you’re ready. Also, each exam corresponds with the chapter you just studied, and completing the exam unlocks the next chapter.

For instance, if you read Chapter 1 of the textbook, watch the corresponding video lesson, answer your workbook questions, and review the FAQ, you’ll be ready to take the Chapter 1 exam. Once the Chapter 1 exam is completed, you’ll instantly see your results and get access to the Chapter 2 materials.

What grade do I need to pass?

At least 75%, which most students easily achieve or surpass.

By the end of the course, you’ll have written 18 short, 10-question exams, for a total of 180 questions. Get at least 135 of the questions correct (75%) to earn your Pn1 credentials. We’ll send your official certificate immediately after you pass.

What if I fail an exam?

You can’t fail a specific exam. Your score for the course is cumulative. So you could do very poorly on a few exams and still pass the course as long as you answer 135 out of 180 questions by the end of the course.

What if I don't pass the course?

If you don’t earn 135 out of 180 points in the course, you can write a re-do exam at the end of the course. You’ll get 5 chances to earn 75% or greater on this exam.

Is the PN Level 1 Certification eligible for CEUs (Continuing Education Units)?

Yes. Here’s a breakdown of CEU’s currently offered:

  • ACE: 2.0 CECs
  • ACSM: 20 credits/hours
  • CDR: 16 sessions
  • CPTN: 14 CPTN CECs
  • Fitness Australia: 15 CECs
  • NASM: 1.9 CEUs
  • PTA Global: 24 CECs
  • REPs UK: 6 credits
What if my certification organization isn't on the list?

No problem. Many organizations accept our course for CEUs on a one-off basis.

To do that, you’ll just submit a summary of the course and a copy of your certificate to the organization for review once you’ve graduated.

How long does it take to get my textbook?

Here’s when you can expect your package (and remember that shipping is completely free):

  • United States: 5-7 business days

  • International: 2-3 weeks
