Hello, my son has a school day trip coming up this week. The school are still unsure if he will be allowed to come or not. They've asked a parent to volunteer but unfortunately we've both got to work that day. My son has situational mutism and ASC, he has an EHCP which is funded. Are they allowed to just exclude him from the trip? If he can't go their plan seems to be for him to spend the day in the school office with the receptionist. Has anyone had a similar experience? Thanks.
