my daughter goes to the health center every morning to take Vyvanse and gets her booster dose every evening before study hall. It is given by the nurse in the morning and the dean on duty at dinner in the evening. As far as accommodations, private schools are under no obligation to follow anything. Each school will have their different processes and what they allow. A 504 is more likely to be followed. IEP’s are not. My daughter does not need academic accommodations or support for her ADHD but if she did, we would be responsible for paying for that extra support at the school she attends. That would include extra time and someone to proctor tests past the class period.
