We have recently identified my oldest DS8 as gifted. Because of this, I've started to consider whether or not my younger children are gifted. I've always considered my children to be smart, but not necessarily gifted. Anyway, I remembered that my DS7 (1st grade)was given the WJ-III (or some portion of it) as part of the application process to a private school we were considering. He was given this rather quickly at the end of the day when he shadowed at the school. I am wondering how to interpret the scores. Here is what I have:

Math Reasoning Grade Placement 2.5 RPI 98/90 SS 117
Academic Skills Grade placement 4.1 RPI 100/90 SS 153
Letter Word Identification Grade placement 4.2 RPI 100/90 SS 137
Passage Comprehension Grade placement 2.4 RPI 99/90 SS 116
Calculation Grade placement 3.5 RPI 100/90 SS 144
Applied problems Grade placement 2.1 RPI 96/90 SS 108
Quantitative Concepts Grade placement 3.2 RPI 99/90 SS 128
Spelling Grade placement 4.7 RPI 100/90 SS 138

I have no idea what any of this means! Any help would be greatly appreciated.
