I want to train as a coach. Which is the best course?

Data suggests that, each year, between 8,000 and 10,000 people globally are completing coach training in a desire to enter the profession. There are hundreds of courses to choose from, with a big price difference. As an aspiring coach, which one is worth investing your time and money in?  In this month's Both Sides of the Coin, host Jenny Butter is in the hot seat. As an experienced coach, she is asked questions by one of her clients, Myriam Carillo, who is exploring a career change into coaching. Myriam has done lots of research into coach training options and wants help understanding which is the best course.
