The Cogat was the test used when DD was in 2nd grade to determine entry into the gifted math program at our school. Her math scores weren't great (104). I remember her saying there were too many things she had not learned to do yet (like multiplication, which has since been introduced in 2nd grade). Her comp score was 129.
I never could understand how she could do so relatively poorly in one math test, but be off the charts in another compared to her grade/district (MAP, for example) or even ACT Explore. But she is in gifted math and she has an A but it isn't her favorite and it is the most challenging subject for her. Funny how are children's brains are wired, isn't it?
Now they give the cogat in the 5th grade for middle school gifted screening and use the MAP for the earlier grades.
