Did you do it thru school or privately? If private, what could I expect cost wise? are we talking 100s or 1000s? im hoping school can and will agree to testing but if they don't?? i gave difficult child's teachers the questionnaire to fill out and only one of the three answered in the 2s and 3s to indicate Inattentiveness problems. I am hoping the doctor will weigh my answers heavily as I am the mom...been dealing his whole life. difficult child is almost 13 and he can be funny happy and nice much of the time, but school work is a brick wall to pound thru. I don't even know if he would cooperate with evaluation??
