.....we are about to run into this same type of issue here in upstate SC.....
.....One of my children is attending a fairly new GT program.....
.....it was started by by a past School Superintendent with the intention of actually giving that small minority of gifted students the same amount of attention that was being giving to "other" minorities of special needs students.....
.....but alas.....
.....the current School Superintendent has found that it (the GT program) represents an untapped fiscal and PR resource just waiting to be hijacked for her own pet project.....
.....So much to the windfall of the local private schools and the dismay of the parents with gifted students without the means.....
.....the mass exodus from the current GT program has begun.....
.....what a shame.....
How old are your kids?
If they're young enough, it's worth your while to fight -- if they're older there's always AP classes, and if there's a local college that will accept them they can take courses there, young and old (not younger than 13, usually).
