I remember being in a meeting with my Pupil Services Director. She said the school needs to meet the student's needs and if they don't have a program that does this, they need to create one. What data do you have to show he only learns in a 1:1 group? We have a private school in my area that's all done 1:1 - Fusion Academy. They have a few campuses. Goes to show he's not alone with needing 1:1 school. I've seen public schools pay for students to go there.
