I agree w/ dagw.
Schools need to have extra classes, extra-curricular classes, etc based on set of similarly gifted students' abilities, or based on set of similarly non-gifted/regular students' lack-of-abilities to improve their abilities. If needed, eligible volunteer or paid teacher should be arranged on specific time. A separate school for gifted students or a separate school for regular/non-gifted students is very-bad/non-gifted idea w/evil & ineffective motives.
The other advantage of having everything in the same school is that it makes moving up (and down) in the sets a lot easier. A kid who is right on the cusp between set 1 and set 2 in math can be put into set 1 for a term and see how it works out. Or a kid who, for whatever reason, starts slipping can be moved down a set and given some extra support. If these changes required moving schools then that will never happen.
