I should have pointed out several posts back, when you said this is public and not private school, that this is a special needs school and as such I would imagine not in the same realm as public school. Without knowing what the other kids’ needs are, I really can’t comment.
It’s very possible that this isn’t the only student with a DNR, but I have no way of knowing that.
My guess if it is a SN school, there is a high percentage of kids with DNRs.
It is a public school, because it operates using money set aside for public schools.
