A 504 is done without professional evaluations. Where I live, the child's teachers each complete a form about the child's academic progress and behavior in their class. THen there is a meeting with all teachers, a school counselor, and you. THey might not include the PE teacher if you don't ask for them to be there. You can also ask to have the school nurse present. You, the teachers, and the counselor decide whether the child has a disability, whether the disability interferes with the child's ability to learn, and what accomodations are needed. I don't know what idiot decided non-Special Education teachers are qualified to determine whether a child is disabled and it affects their learning. Even the nurses can be ignorant. Also, teachers and nurses may be biased to being with. In my case, we even had a nurse who wouldn't admit migraines could ever, under any circumstances, be disabling.
