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).

.....9,11,and 20.....
.....and it's the 11 year old that's in the GT program.....
.....(i know, we had a dry spell there fer a while! lol).....
.....we were lucky that the 20yr old decided on his own that public school was not for him.....
.....he attended FUMA in VA for High School(No Better School in the country imho).....
.....and is now attending UM (Montana),and it's pretty liberal according to him :(.....
.....we are probably going to let our middle one stick it out one more year in the GT program and then move her and the "baby" into a private middle school together.....
.....Thank You for those links!.....
