I'd ask for all of the subtest scores not just the FSIQ or GAI. I mean all of the scores that feed into the indices not just the index scores as well. It is worth knowing if there is a lot of variation there that is making the overall number less remarkable in and of itself. For instance, I have one child who had a moderately gifted score on the perceptual reasoning index of the WISC, but in knowing that an overall score that looked gifted but not remarkably so was due to three scores that were 25th percentile, 99th, and 99.9th, it did raise more questions and the realization that something else might be going on.
Good luck. I hope that you don't have to wait too long for the results.
Given her age, I'm assuming that the Weschler test used would have been the WISC-IV (Weschler Intelligence Scale for Children version 4). There is a remote possibility that they used the WPPSI, the preschool version, b/c you can give that up to age 7 yrs 3 months, but hopefully not b/c she is more likely to have hit ceiling issues and not get as good of a measure given her closeness to the age limit of the test.
The WISC has three indices: VCI (verbal), PRI (perceptual reasoning), WMI (working memory), and PSI (processing speed). There are then subtests that feed into the total scores for these indices and all four indices are used to calculate a FSIQ (full scale IQ). If there is large discrepancy btwn the PRI and VCI indices versus the WMI and/or PSI, an alternate IQ score called a GAI (general ability index) should be figured instead. I'd want not only the VCI, PRI, WMI, and PSI scores, I'd want the scores for the subtests within them. One of my kiddos had those wonky scores I mentioned above within the PRI index and, while all of her scores (PRI, VCI, GAI, and FSIQ) were gifted, we were told they were likely an underestimate given how erratic she was and she has, honestly, always outperformed those IQ numbers. For her, I don't really think that she is twice exceptional so much as she is a slower deeper person and one who had come off a terrible school year just before testing and who was uncooperative as a result.
Both of my kids have taken the WISC IV and I am a gifted children's coordinator for my local Mensa group so I've had others share their kids' scores with me in the past. If you have any questions when you get those scores, I'd be happy to give it a try to see if I have any insight. Feel free to send a pm.
