No guarantee of portability any direction, even within the same school district!!
However, ONCE the 504 eligibility has been determined SOMEWHERE, it can be harder to then deny it on second look, so long as medical condition has not changed, KWIM?
For example:
"So, how is it that a team of 8 at previous school could determine child qualified under Section 504 and yet this team of 5 (parents dissenting) cannot, especially when the child's qualifying disabling condition remains same and is adequately documented?"
The prior finding of eligibility is additional documentation of eligibility in current meeting, so long as have current supporting med documentation (suggest strong letter from allergist NOT med records for them to wade through, misinterpret, and violate privacy with).
Make sense?
