Coaching is a form of development in which a person called a coach, supports a learner or client in achieving a specific personal or professional goal by providing training, advice and guidance.

​

The learner is sometimes called a Coachee. Occasionally, coaching may mean an informal relationship between two people, of whom one has more experience and expertise than the other and offers advice and guidance as the latter learns; but coaching differs from mentoring in focusing on specific tasks or objectives, as opposed to more general goals or overall development.
