The
IHSAA has in its by-laws a rule that prohibits
school-owned uniforms from being worn in non-school contests. Again, this is an IHSAA By-law/Rule. The IHSAA recommends that Middle Schools follow and abide by the same rules and guidelines, but; there is no actual governing body for Middle Schools, so, it is up to each school system, as to, which rules and guidelines they will recognize and enforce. I'd recommend that you consult your school administration to determine if there is, in fact, a conflict or potential problem within your program. As for the IHSWCA Middle School State Championships event, this is not anything that we as officials or event administrators can be expected to enforce or be concerned with, in that, we have no idea what each Middle School's ruling would be; nor, if a siglet/uniform would be school owened.
