My partner is dealing with his ex-wife request to change the school their ADD/ADHD daughter attends. While she has had many difficulties in her education thus far (she is 9 years old in the 4th grade), her IEP (Individualized Education Program) shows a slow/consistent improvement.
We are concerned that a change of school/teachers/classmates/routine/geography will be very damaging. What is the last theory/advice on this issue?
