Do they use ability-grouping for some subjects/topics in order to let high-ability kids work together?
I would also ask why they prefer to use diffentiated instruction exclusively--their answer might give you some hints about how they view the needs of gifted learners, since many gifted experts aren't convinced that differentiation can meet everyone's needs in all circumstances.
They group the higher ability kids or kids can go up a grade if needed. The principal thinks that gifted kids need to be with the other kids rather than isolating them. He said he thinks differentiation works better than a pull out program.
