Hmm, I'm not sure exactly what you are asking. Do you have specific test insight and questions? Your age cut (7) is not significant for any of the tests that come to mind.
For example, one of the most popular brands is Weschler's. Here the WPPSI is the preschool test, and runs about 2.5 up through 7, but age 6-7 is "overlap" with their "big kid" version, the WISC-IV which starts at 6. If Weschler was used, the WISC-IV would have been the right test, but again...that cut is at 6.
Any test can have the wrong data punched, if the wrong age/birthdate is used. Most official reports should include the age of the child though.
Could you clarify?
