MIT Human Resources department makes the following observation about coaching:

In a performance management cycle, coaching means providing ongoing feedback and support to the employee throughout the year. Coaching gives the employee an opportunity to hear about aspects of his or her performance in "real time" and to play a role in figuring out how to best adopt or modify their behavior for success.  (https://hr.mit.edu/learning-topics/leading/articles/what-is-coaching)

Concordia Market provides a listing of women and men who have completed formal training and in most cases, certification to be performance coaches.  They specialize in the ministry environment.
