It is a bit of a unique program, the way it is designed for all kids, she is at the (specialist) school 1/2 the day, and her regular school the rest of the day. The intent and design of the program kids are enrolled in the specialist school for 2, 3 years, and then mainstreamed back into regular school. Other than me (for the financial shock) everyone else is recommending this course of action (pediatrician, primary school teachers, school psychologist, other parents). We have talked to other parents who have kids with similar learning difficulties (dyslexia) who have gone through this program, and it has been overwhelmingly positive, their only regret being that they waited to do this. They also mentioned corollary benefits of the school on child's self esteem, and basic organization and planning skills that generalize to both school and outside of school. So while this is going to be financially painful, I feel this is the right decision.
We also have a 529 for her with about 4K in it. I would rather not touch it (want to save it for higher education), but that is another option.
