Isn't the OLSAT a screener? Much like the CoGAT? If so, it's a group test and misses some gifted kiddos. Have you checked the Hoagies list of testers? Our tester was on that list and was outstanding.
It is used as a way to determine the academic needs of children. The district uses it to find those who need interventions.
We received a list of testers (I.Q.) from the local Gifted Children "Network", but we were hoping there was some way to have him re-tested with the OLSAT (is this even done right away? or is it a matter of waiting until the next testing season?)
I've read that testing children younger than third grade may not be desirable in order to "prove" giftedness because of the whole argument that kids who are advanced even out with their peers by third. If we're to spend money on a psychologist, I want that person recognized by our district and I want DS to be of an age that the argument of him being a hot-housed child one that won't hold water.
