I think the takeaway is that just because it's a "gifted" magnet/charter/public/private school, doesn't mean that:
a) they understand the difference between intellectually gifted and high achieving
b) it will be right for all or any specific gifted child
c) differentiation is supported (the "all our kids are gifted argument"
d) the quality of instruction is any better than any other school

My advice to people looking for a better educational fit for their HG+ kids is to look outside the box and not to rely on a school's marketing material or label.
