The Handbook of the National Federation of State High School Associations provides rationale for the following eligibility rules that are common to its member associations across the USA:

•  Age

•  Enrollment/Attendance

• Maximum Participation

• Transfer/Residency

• Academic

• Non-School Participation

• Preparticipation Evaluation

• Restitution

• Amateur/Awards

• Recruiting/Undue Influence

Here’s the rationale provided by the National Federation for the transfer/residency rule:

“A transfer/residency requirement: assists in the prevention of students switching schools in conjunction with the change of athletic season for athletic purposes; impairs recruitment, and reduces the opportunity for undue influence to be exerted by persons seeking to benefit from a student-athlete’s prowess.

“A transfer/residency requirement: promotes stability and harmony among member schools by maintaining the amateur standing of high school athletics; by not letting individuals other than enrolled students participate, and by upholding the principle that a student should attend the high school in the district where the student’s parent(s) guardian(s) reside.

“A transfer/residency requirement: also prohibits foreign students, other than students who are participants in an established foreign exchange program accepted for listing by the Council on Standards for International Educational Travel (CSIET), from displacing other students from athletic opportunities.”
