At a local private Gifted school with which I am knowledgeable, they accept only 95+% (WISC) and each grade is grouped in 4 levels PK-K. Groupings are done separately for Math and Reading. Beginning in the 1st grade, 2 grade-levels participate in grouping together allowing for a total of 8 differentiated placements. That arrangement was the best we have had for appropriate curriculum for our 2e PG guy. Unfortunately his "2e" was labeled bad behavior before we understood what was going on and the classroom became so damaging he was literally pulling his hair out.

The local public is very one-size-fits-all gifted. I sure wish we could have our Gifted School academics with the age-appropriate level of physical activity of our public plus the appropriate accommodations for his disabilities that we found at neither.
