WIAT-II UK for Teachers (WIAT-II UK -T) - Frequently Asked Questions

How should I score the WIAT-II-T Reading comprehension subtest when the reverse rule is applied?

To score the WIAT-II-T Reading comprehension subtest when the reverse rule has been applied, test administrators are to ensure that they’ve calculated the weighted raw score before the standard score. This will then take into account the item set the child took. The standard score is then calculated for the actual age of the child (so that you are always comparing a child’s performance to their age peers). You should use table B1 to convert the total raw score to a weighted raw score. Then use Appendix C to obtain the standard score (based on the chronological age of the child). As long as you have followed this procedure, your calculation should be correct. 

For example, if you used the reverse rule on a 12 year old child, you would go back 3 start points to age 9. You would then administer the age 9 items only. You would add the scores of all of the comprehension items within the administered age level (in this case age 9) only. 

Therefore, on table B1 you would refer to the level administered, not the age of the child. So in the example above, you would look at the age 9 item set as this is the items that the 12 year old child answered after the reversal rule was put in place.
