Donna: My son has a visual impairment. What materials do you suggest I get to best advocate for him and receive the services he needs? Right now he is in a private school and receiving vision services only quarterly, no O&M, no braille though we have requested it and the district knows IDEA requires it. We are moving to a different state in June & will likely do another year of private preschool followed by public kindergarten. In the meantime, I am teaching him braille at home and already have the materials to do so. Interested mainly in better understanding the law and procedures to prevent this situation in the future. Any help is much appreciated. Thank you.
