Study Results from The International Coach Federation, the leading coach professional organization, has conducted and reviewed studies about coaching in organizations. They found an average return of $4.30 to $7.90 for every $1 invested. They also found that training combined with coaching increases productivity by four times more than training alone (which makes sense given that coaching works over time to reinforce the work of training, and also given the research that almost 85% of most training content is lost after two weeks).
