For some absurd reason the OHSAA has protected the document from having sections electronically copied so I'll summarize and give you the link. Link:
OHSAA Bylaws
Section 7 deals with transfers and states in part:
1. The transfer rule only effects students in grade 9-12, in both public and private schools.
2. If a student tranfers after their first day of 9th grade (or after participating in a "contest" prior to the school year starting their 9th grade year) they must sit out one year, except if:
a. The parents/guardian move from one district into another.
b. If guardianship of the student is changed and the new guardian lives in a different district. Still requires Commisioner approval though.
c. If the party to a shared parenting plan makes a residence change.
d. The school closes or is annexed by another district.
e. With the written agreement of the superintents and the Commisioner for the students mental or physical well-being
f. May change from one HS to another in the same district ONCE with superintendent approval (eliminates eligibility for e. above).
g. A student who is self-supporting may transfer back into the school district of the parents with Commissioner approval.
h. If transfer is to the State School for the Blind or the State School for the Deaf.
i. if a new school is established in the resident district.
