I'm not the score expert, but I'd want to know the GAI if I were you. That's basically the score eliminating WMI and PSI. A lot of gifted kids get their FSIQ score dragged down because of WMI and PSI. There has been a lot of discussion on whether or not PSI and WMI measure general intelligence. I think I did see that DYS for example, now accepts GAI if it meets minimum:
Wechsler Intelligence Scale for Children-IV (WISC-IV) Standard score 145+ (99.9th percentile) Verbal Comprehension, Perceptual Reasoning, General Ability Index (GAI), or Full Scale
