Clarify the expectations of the faculty member at the outset of the practicum.  Ask, "What is my most important role with this student from your perspective?"  The answer will vary depending upon the student's previous experience and the role that the faculty member is taking with the particular student.  Seek ongoing feedback from the faculty member.  During faculty visits to your practice setting, share your observations and perceptions of the student's performance, validate your approaches, and ask for additional suggestions.  Also ask the faculty member for his or her assessment of the student's needs at this point in the practicum.
