There's a listserve on the Internet just for parents and professionals who are interested in the needs of children with CAPD. The address of the listserve is: email@example.com In the body of the e-mail, write: Subscribe CAPD your name.
In the meantime, call the toll-free number for the Learning Disabilities Association of America at 1-888-300-6710 to see if they can recommend an advocate in your area. From my own experience, I've found that the only way to get the public school to pay for private services is if you can prove that the services they can provide are not appropriate for your child's needs. Good luck!
