I would love to see this concept implemented in an urban setting, under the context of a general education school (rather than a magnate, etc.). While I think it would work for some, I suspect many of these disruptive children probably have major family issues that make it difficult or impossible for them to focus on learning. See: Maslow's hierarchy of needs.
It would certainly be a good starting point though. Something must change, and mandatory testing changes nothing.
