Our 6 yo son was recently given the Terra Nova as part of the gifted ID process. Results came back as slightly above average despite reading at a 4-5th grade level. Went to a private tester who administered the WJ. Scores came back in the high gifted range with math above 99. However his understanding directions subtext was only a 43. Suggestions included testing for APD and ADD. He is too young for the APD test, but the symptoms just don't seem to fit. He has 2 siblings and a parent with ADD, so we are familiar with it, and it also just doesn't seem to fit. Clearly there is something there, but what else could impacts ability to process directions?
