MINNEAPOLIS (AP) - The Minnesota High School League will vote on establishing guidelines for transgender student-athlete participation.

The guidelines would be the first in the state for transgender student athletes. The proposal describes how schools should accommodate locker room privacy and outlines the medical documentation that students must have to identify themselves as transgender.

The league drafted the plan with advice from OutFront Minnesota, an advocacy group for transgender issues. The proposal has drawn opposition from the Minnesota Family Council and the Child Protection League Action. Opponents urge parents to contact league representatives before Wednesday when a public hearing will be held.

The league, representing nearly 500 schools, is expected to vote on the plan Thursday.
