There seem to be two main kinds of GT programmes in schools;
1/ Reward for high achievers - mostly well behaved bright to MG girls.
2/ Holding cell for clever kids no one can be bothered with. Mostly boys.
I have to tell you that DD's gifted magnet looks nothing like either 1 or 2, but then, it's an IQ-based program (130 and above). Achievement tests are not used for admission. Students do initially get tested based on teacher rec/checklists, but you can also request testing, I believe, and they also take outside test results.
I'd be...careful about the implication that girls are obedient and MG and boys are smarter and outside the box.
