NCAA Bylaw 13.02.5.1 [Permissible Recruitment Activities for Enrolled Student-Athletes]
a) Off-campus contacts. Off-campus, in-person recruiting contacts that are unavoidable incidental contacts between enrolled student-athletes (or other enrolled students) and a prospect are permissible if such contacts do not occur at the direction of a coaching staff member.
(b) Telephone contact. It is permissible for an enrolled student-athlete to receive telephone calls made at the expense of a prospect subsequent to July 1 following the completion of the prospect’s junior year in high school. Telephone calls made by enrolled students (excluding student-athletes) pursuant to an institution’s regular admissions program directed at all prospective students shall be permissible.
(c) Written correspondence. It is permissible for an enrolled student-athlete to engage in written correspondence, provided it is not done at the direction and/or expense of the member institution.
(d) Unavoidable incidental contact. If unavoidable incidental contact occurs between a student-athlete and a prospect (even at the prospect’s high school), such contact is permissible, provided the institution had no prior knowledge of the occurrence of the contact.
