I wasn't in TAG at my elementary/middle school, not because I wasn't smart enough, but because to get in one of the tests was they'd describe something abstract (a circle on top of a box on top of a flower, something like that) and between my AS and my dysgraphia, which would have prevented me from drawing it even if I could visualize it well enough to do so, I pretty much failed miserably. But I was definitely smart enough, and wound up being recruited by Center for Talented Youth, which allowed me to take SATs in 7th and 8th grade (and score higher than the average high schooler taking them) and then I was eligible for CTY programs. I wound up not doing those, but did Summer Institute for the Gifted (a similar summer program to CTY, but focus on a broader variety of topics, instead of CTY where you're doing one class for the whole day). That wasn't through my school, but it was a gifted program. And in college, my SAT scores were good enough to easily get me into the Honors Program, but my High School GPA was not. Mainly because for the beginning of high school, I was slacking, before getting it together now.
