I recently received the results from my six year old first grade son's WISC-IV. His results were VCI- 114 (82nd percentile), PRI, 137 99th percentile, Working Memory 110 (75th percentile), Processing Speed (79th percentile) My question is whether or not the difference in scores is statistically significant. I have also heard that if there is a big difference across scores that it can point to other issues such as an LD, or ADD/ADHD. I have reason to suspect that my son possibly has ADD and dyslexia.Although he is very bright and is VERY good at math there are some issues that really concern me. For example, my mom had to drive him to school one day and he insisted that he had NO idea where his own classroom was, even though it is his second year at the school and it was already several weeks into the school year. He also forgets things at school quite freqently, most recenty his own backpack! David also has frequent temper tantrums and still needs to wear a pull up at night. Any advice would be GREATLY appreciated.
