I normally tutor students privately. There is one student, however, that I have managed to strike up a bond with. So, for the past five years, I have not only tutored this student, but I have also acted as a mentor and guidance counselor. Our goal is for this student to get a PhD. In addition, I am even conducting outside scientific research projects with this student, with me being the lead investigator. We are even close to publishing a paper together. This is obviously an EC since this is not at all tied to the university. But, how would I go about describing this and is it something that can be put in an application? The student's parents are more than willingly to affirm that I was officially hired by the them.
