A mentoring contract is document that sets the paramaters of a forthcoming mentoring relationship. These contracts can help set goals and lay down specific ground rules before the relationship begins, in order to help prevent future confusion and misunderstanding. Items that are commonly used into such a document include plans for managing confidential information, the duration of the relationship, frequency of mentoring meetings, and specific expectations and goals.

Notice how although the second mentoring contract is much longer, it still has the same major components that the first contract contains. The length and detail of the contract can vary from relationship to relationship, however all mentoring relationships should begin with a contract. It's a great way to start things off well, and ensure that the mentoring journey is guided to a successful end.
