I'd like to see that the body of evidence includes anything that is a positive indicator but that any "negatives" do not rule a child out. So a high IQ would be a positive, you're in. Very high achievement, check- you're in! Demonstration of extreme abilities in creative pursuits, check- you're in! Teacher observations (by more than one, I've seen single observations be too tainted), check- you're in!
Unfortunatly, it works usually that high achievement is THE indicator of whether or not a child will be successful in a school's GATE program. Not whether or not they're gifted.
