I have a 9 yr old grandson who has adhd takes meds for it. I recently paid for a class trip 140.00. He has a 504 plan at school. The permission slip stated if children get into any trouble or write up 30 days prior they are not able to attend. We'll he was thrown off 2 class trips in that time period? Because he has a disability is it legal to not let him go on the trip on or off school property? I was just informed they are not allowed to do this. I feel in my opinion they set him up for failure. He was punished for taking something off the teachers desk that didn't belong to him. Why both trips? Any advise would help. Thank you
