The teacher needs to be willing to help the tutor understand what the student is supposed to be learning by providing course outlines, text books (if requested and available), and other similar information.
The teacher should also be willing to help the tutor understand the kind of help the student needs. Is the student having problems with the facts of the subject or with their application? Is the student bored with the class pace and need some enrichment activities? The teacher should be ready to help the student and tutor to establish objectives for tutoring. This may be more important in younger grades where the student is less able to help guide the tutoring sessions to meet his or her needs.
