By the way, What Do the Tests Tell Us provides a very interesting take on the OLSAT that may be directly related to your DD:

Quote
The most common group intelligence tests, OLSAT and CogAT, are used in districts and programs across the country. Notable gifted professionals recommend them for screening potentially gifted children. However, a small study noted a potential problem with the OLSAT and very gifted children. While the correlation between group and individual intelligence tests is quite high for average scores, in this study that correlation almost disappeared for gifted scores. This means that while an average child will score very similarly on a group IQ test and an individual IQ test, a gifted child may not score similarly at all. And the study suggests that this group test may even result in a negative correlation for some gifted children: the more gifted the child, the lower the group ability test score! "Investigations of the Otis-Lennon School Ability Test to Predict WISC-R Full Scale IQ for Referred Children" by Anna H. Avant and Marcia R. O'Neal, University of Alabama, Nov. 1986, ED286883 Though this study is no longer available from AskERIC, it can be obtained on microfiche from most education university libraries.
So it's a bit ironic that the OLSAT, which is often used as a gifted screener, may actually act more like a gifted masker in some scenarios.
