The reason that the newest version of an IQ test is usually given is that they need to be re-normed every few years. Google the Flynn Effect for info. Basically, if you are given an older IQ test, your scores will be higher than they are on a more recently normed version. That is the reason why DYS doesn't accept the SB-LM (which is version 3 of the SB, I believe) anymore. One person tested on the SB-LM and then given a more recently normed IQ test might test many points higher on the LM -- sometimes as much as 20+ points higher on the older test. Hoagies has a comparison chart for people who have taken both the LM and a new test, such as the WISC-IV:
http://www.hoagiesgifted.org/wisc_vs_sb_l-m.htmThe SB-IV isn't as old as the LM, of course, so it shouldn't be inflating scores as much. The SB-V does have an anecdotal history of underreporting IQ scores or netting much lower scores than other IQ tests, though, so perhaps that it why your psych didn't give that one. Dr. Ruf is now considering a score of 121, I believe, to be moderately gifted on the SB-V.
Like Dottie said, her scores appear solidly gifted. If you want the scores for something like DYS, I'd get some qualifying achievement scores and/or retest in a few years with the WISC-IV.
I could certainly be wrong b/c I am not the DYS people ;), but, like Dottie, I assume that they are still taking the SB-IV b/c they will take old IQ scores coupled with more recent achievement scores or vice versa. If a child was tested on the SB-IV before the V version came out and had qualifying scores and then later got the qualifying achievment scores, that would probably do it.
