Based on what I've seen with students, it is a nice touch to include supplemental materials with an application, particularly if a student's talent is in a non-athletic area. Supplemental materials may included a DVD, CD, website or other means of helping college admissions officers - or perhaps members of the appropriate department - learn more about the candidate. Colleges are very straightforward about what to submit and how to submit it, so students should seek guidance on the college website. The most common answer is that the college welcomes submissions but does not give back any materials. Certainly, a talented student should try to submit materials but only following the instructions of the particular college. He or she has nothing to lose and perhaps something to gain. There are even independent counselors who advise students in the arts and might change his or her advice depending on the talent and profile of the candidate.
