There is no link to the GE/AE tables freely available. If you really want to know them ("for entertainment purposes only"), pm me.
HOWEVER, keep in mind that grade/age equivalents on the WIAT-III (as on most norm-referenced instruments) are not "true" scores indicating that your child actually performs at the stated grade or age level. They are derived from the standardization group's performance, and mean only that the raw score obtained by your child was the same as the raw score obtained on that task by the 50th %ile of the norm cohort so named. IOW, if your child has a GE of 8.5, it does not necessarily mean that he can do mid-eighth grade work, or that he has mastered all content up to that grade level (not all content was sampled on the test). It means that he obtained the same raw score as the median student in the norm group at grade 8.5 did on this specific set of items. Remember that the design of this kind of instrument is not grade placement or leveling; it is intended to compare a student's performance to their age or grade peers, not students in other age or grade brackets.
For obtaining more accurate grade or age equivalents (placement decisions), criterion-referenced instruments are generally better than norm-referenced instruments.
