Achievement testing. How old is your Dc?
For example, if you take an early reader that is reading, let's say at a 1st grade level at 4, before starting school; he'd probably get that 99.9% reading score, since the vast majority of kids can't read before K. However, there might very well be (and in fact they are), many gifted kids, even PG kids who were not reading at 4. Once they start reading, they progress so quickly that they'd be further ahead than the first kid.
For example, my dd "only" started reading at 4 years 2 months, but by the time she started K, she was reading at a 6th grade level (in terms of books she picked and read).
The application deadline is the 14th, so it might be a bit tight for December. Probably the hardest part is to find the reference/recommendation letter.
