Your question should be refered to the Wellington school your daughter will be attending. I would recommend that you speak to the specific needs of your daughter, the services available, and amount of time your daughter will recieve these services weekly.
I cannot speak for Wellington specifically - but the people that I know in Wellington, Boynton Beach, West Palm Beach and Lake Worth (just Eastand just South of Wellington) drive to Boca Raton or Miami for the pediatric specialists there. They have more medical resources at the University of Miami and at Boca Raton Community Hospital for children with special needs... plus there are other resources including support groups, play groups, therapists etc...
I would personally consider investigating further South to the resources in Boca Raton. If you have any questions, I can refer you to parents, world-class child psychologists, doctors and community resources in the South part of Palm Beach County. Wellington will be a 30-40min drive to Boca Raton - Boynton Beach will be 15-20min.
Plus - if you have to choose private schools, the options are more plentiful and are stronger in the South part of the county. Boca Raton's public schools are all A rated...as are West Boynton Beach

It also has contact info. and I would contact them immediately to see how they respond to your questions.
Believe me when I tell you I know how much these concerns mean to you and I hope if any at Trulia are familiar with this school they will give you their opinions.
I sincerely wish you the best, Dunes
