I have a child like this as well. She did above avg on the group ability test but was clearly gifted on the individual IQ test. It has been the same thing with group vs. individual achievement tests. It can be very frustrating as a parent when your child isn't getting recognized as what she is due to poor group test results.
I guess that I see a distinction btwn prepping a child for a group test in the hopes that she will do as well as she already has on an individual test vs. prepping a child with answers in the hopes that she will appear more able than she really is.
