Whither the specialist school? (UK)

Now that the numbers of specialist schools are heading towards saturation is it time for the powers that be to consider specialism 2.0 and exactly what that might mean in terms of REAL collaborative partnerships?

Everything seems to be still based on the old "pull" model and I really think it needs "push" if we are to move to the next level.

Creativity, Collaboration and Curriculum change; but how do we avoid leaving people behind?
