No. Coaching is an unregulated industry. Just as you can call yourself a tennis coach, you can also call yourself a life coach, mindset coach, health coach etc. “Coach” is not a term governed by law unlike a “Doctor” or “Lawyer”.
Most new coaches lack confidence so they believe the certification will give them that. What often ends up happening is they go down a never-ending path of coaching courses for many years and many tens of thousands of dollars, always striving never arriving.
Your clients care more about how confident and professional you are as a coach and the results you help empower them to achieve.
