Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Differences in Stanford Binet and WISC ?

I am curious if anyone else has had wildly different scores on these two tests? DD had a GAI of 146 on the WISC-4 (VIQ=149 and PRI=136) and then received A 160 on all sections of the Stanford Binet 5. We had her tested privately with the WISC and the school system would not accept outside testing so they administered the Stanford Binet. Any idea what is different about these two tests? Thanks for any imput, the tester did not seem to know what could have happened. Other than perhaps some of the WISC is timed and the SB is not?
