One thing to keep in mind, is that at this age, the CogAT is READ to the child. Fluctuations or leading with a certain tone of voice can mislead a child, or the child. There are actually several areas of the test, though broken down into those 3 subtests. There is a vocab section, which is more along the lines of the teacher saying "Which one is a reptile" and there are 3-4 pictures to choose from and the child picks the correct picture. There is a section where they hear a story and then there are several pictures and then the child chooses the picture to draw conclusions from what they heard. There is an abstract shape section in the math portion, etc. So.... because a child is a good reader, having the test read to them, and using pictures and what not to choose answers may not be good for some children. If you go to the website, there is a pretty good description of the test. HTH!
