My 6 yr. old had the Woodcock Johnson III achievement test and had similar scores to your child on the reading/writing subtest. She was also given Math subtest and scored a little higher on that: Broad Math of 159 and Calculation 156 and Math Fluency 144. She was not given/test for a GIA. I am just wondering what you want or need the IQ test for, is it to qualify for some sort of program? My dd was tested for the purpose of grade acceleration and I am new to all this. By the way, I was told the writing score is expected to be lower because they haven't been taught any writing skills at this age.
