Our state has a pretty good ID program. If you hit the right scores on the assessments, you're in, end of story. If you just miss the cut-off, there are human factors (teacher recommendation, etc) that come into play, which can serve to benefit 2e, gifted underachievers, etc. Of course, this also opens the door to hothouse flowers, but no system is perfect.

Content delivery and implementation/following of formal policies are areas where we could use significant improvement.
