Wondering how large of a spread people have seen in their children's scores? My DD's WJ-Cog GIA qualified her for DYS back in 2012, but her achievement didn't meet the cut-off and she was denied admission. Now that the criteria is one test, I thought we'd reapply, but the test is too old. So, I had her tested with the WISC-IV (in a possibly suspect environment--more on that below), and her GAI is considerably lower. Just curious if anyone else has seen so large a spread. Is it age, or the tests? Or, is it not that large of a spread, because I should ignore FSIQ and just look at GAI?
2011:
WJ GAI: 152 (age 6)
2015:
WISC IV: 135 (FSIQ) and 144 (GIA) --age 10
Note on the "suspect" environment: we tested through the NJ Gifted Child Society, because the price was right. Evidently, it's screening for their organization (which requires FSIQ of 130), and we didn't get a full score, and the test was done relatively quickly.
