So I just got back results of my dd7’s Wisc V testing. She scored 2 standard deviations below my DS9 Wisc IV score. She is pretty smart but definitely not as far to the right as my son. However, we were quite shocked she scored so low comparatived to her sibling. Is this common? I thought researched showed that siblings score normally with 10 points of each other. She was still above average or mildly gifted range but not even close to her DYS brother. And she has no learning issues or behavioral problems. She’s a happy normal go lucky kid. My son is the one with 2e issues.
