Maybe I'm missing something, but I don't understand why "her parents worked with her at home" and being placed in the appropriate class because she has mastered prealgebra are incompatible concepts. "Her parents worked with her at home" so she is ready for the class.
As a former homeschooler and current afterschooler and parent of an HG+ kid who is accelerated three years in math, I would not have a problem with my son's algebra teacher saying, if the question came up, that he is in that class because his mother worked with him at home. I did, and I still am.
