I just think there should be multiple data points and a child should not be excluded based on a single score that is set at an arbitrary level. Of course, really getting to know the kid is more costly and time consuming. But I think that school districts who set these arbitrary levels demonstrat IMO a lack of understanding of both giftedness and the tests themselves. For example, I am pretty sure I have read that the makers of the CogAT say that it should be used as a screener only.
