Just a quick example of not following the 10-point rule.
I have had all my children tested by the same tester.
Oldest son DYS- tested PG on the SB-V (age 5) and WISC-IV (age 8)
Daughter tested average on WISC-IV (age 7)
Youngest son - tested MG on the SB-V (age 5).
There were 40 points between the highest and lowest overall full scale IQ.
There are no major 2-e issues that I am aware (except a speech delay by the youngest son). My children are very different from one another and I do believe that their score are accurate.
