I've always been intrigued as to how DD would score medicated. It was at her WISC testing that ADHD was flagged up as a possibility. A year later we started medicating after seeing an ADHD specialist.
I'm just going to assume her GAI (170 with extended norms/157 without) wouldn't change much but her PSI and WM scores would change significantly.
I guess we can use her scores as a ball park figure.
