I think it would be generally more challenging to find success stories here. Hard to say what is the measure of success. We have also found reasonable success with a Title 1 magnet public school, DS8 is constantly learning and differentiation is working fairly well. Though it took two or three months for DS' excellent teacher to get what he needs (rare enough that many teachers have to learn from a case of one.) Ideal? not exactly, having instruction at level in math rather than soloing online would be better. And next year will be a new teacher, though we hope there is a good warm hand-off (do schools do that? as in a few hour or day meeting between elementary school teachers to talk-through the students being handed on.)
