Each group is relating to grouping for small group work/practice of curriculum instruction. I didn't know if it had to do with ability grouping being a closer intellectual grouping and cluster grouping being a looser peer grouping. School has already told me there isn't a good peer group in grade and can't meet needs within current classroom setting even with GIEP. I was curious if the ability to cluster change was coming from them releasing themselves of need to address child's actual needs vs just getting in the ballpark?
