In fortunate cases, even an at-grade classroom is just a holding tank, but the learning is quite unfettered. Teacher and administrator attitude is everything. And if parents can be supportive allies to teachers, and do some heavy lifting at home to support special requests, I’ve found the response to acceleration can be quite enthusiastic.
The criteria I formerly used to pick schools for my DS have evolved quite a bit. In order of importance now are:
1. Flexibility
2. Openness to new ideas
3. Humility
