DD9 scored at a gifted-but-not-DYS level on the WPPSI at age 4, with no substantial subtest scatter. At age 8, she had substantially higher scores (DYS-level GAI) on the WISC, and also substantial scatter that earned her a dysgraphia diagnosis.

It's interesting that she didn't have nearly as much scatter on the WPPSI, which I think has to do with fewer fluency tests and pencil-and-paper work, so she wasn't challenged with the stuff that is difficult for her.
