What is a local version of the WISC?

the school decided they needed further testing by the school psychologist
Some may say that learning the reason(s) why the school decided to retest may be key.

Some additional thoughts -
1. Scores vary between tests as noted on this Hoagies' page
2. Kids can perform differently on different days, this is why any test is considered a "snapshot".
3. Might a mistaken belief that "everyone evens out by 3rd grade" be coming into play?
