There is a difference between supervision and mentorship. Supervision is typically task-oriented, for example, completion of a specific work plan activity. Mentoring is more about fostering long-term development and is often less formal. Keep in mind that a student can have a different supervisor and mentor. Although some supervisors may at first want to fill the mentor role as well, students can benefit from having multiple people help guide their professional development. 

Effective supervision requires ongoing and clear communication between the student and supervisor as well as a structured work plan or assignment. Regular check-ins will ensure the student is on track and understands the required tasks and timelines. Be available and allow enough time for discussion and clarification. 

With a focus on longer-term development, good mentors set mutual goals for development, allow students to make their own decisions, stimulate thinking and reflection, and help open doors and identify opportunities. Mentors should be well established employees with a broad understanding of the organization. In addition, mentors should be strong communicators, flexible, empathetic and available.
