School Advocacy

The school where my daugher attends 2nd grade is treating her as if she is incapable of learning and pulls her out of class under an IEP for replacement with much simpler curriculum that she is capable of doing.  they don't even bother to try to understand the underlying Mito condition, since its very mild, and pull her out of class to study in a small group with kids with ADD and other conditions.  She is becoming bored and dissolusioned with school.  How do you take action to get the school to adjust their plan?  are there any good legal network sites that will help me identify advocates who can assist me in this process?

any advice is greatly appreciated.
