NCAA Bylaws 13.01.4, 13.02.12 and 13.02.13.
Recruiting is any solicitation of a prospective student-athlete, or their relatives or legal guardians, by an institutional staff member or by a booster, for the purpose of securing that prospect's enrollment and participation in the institution's athletics program.
Boosters are prohibited from making in-person off-campus recruiting contacts or telephone calls with a prospect or their relatives or legal guardians. On-campus contact is permitted, as is written communication, and no booster may communicate with a prospect in any form before June 15 immediately preceding that prospect's junior year of high school. Recruiting contact by boosters during a prospect's official visit is confined to campus.
Who is a prospect
A prospective student-athlete is a student who has started classes for the ninth grade. A younger student becomes a prospect if Biola provides them, or their relatives or friends, financial assistance or benefits it does not provide to prospective students generally.
Prospect status does not end at signing. It ends only when the student officially registers, enrolls in a minimum full-time program of studies and attends classes in a term of a four-year college's regular academic year, excluding summer, or participates in a regular-squad practice or competition at a four-year college.
