I want to put my son in home study, but have been told I can't because of a waiting list. Is there an alternative to getting my son the education he wants?
There are also ways to deal with noisy classrooms. Your son should ask to be seated in the front so it will be easier for him to hear what the teachers say. He should also be allowed to wear headphones to listen to music during study periods in order to block out the noise. And it certainly wouldn't hurt for him to have several like-minded students join him in discussing with the teachers how disruptive the classroom noise is to their learning and how the situation could be improved.
You probably should consider whether there are other problems beyond noisy classrooms that are causing your son to hate school. Does he have friends? Is he in activities? If he participates in things he enjoys beyond the classroom, he'll probably like school more. One easy way for him to have a social experience with other students is to be an office aide. Or if he's more gregarious, joining school clubs could help him find a comfortable niche.
