Thanks, both of you. Polarbear, I once charted DS's scores using your breakdown (found in another thread a while back) and it was eye-opening to see the impact of his dysgraphia laid bare.

Aeh, DS took the test at 6.5 years and DD took it at 6.25 years. Thank you for the explanation of the age/grade impact, it explains the reading tests. DD just finished kindergarten and had a perfect score on the early reading subtest, so she was given the reading comprehension subtest, as well (grade 4 result).
