Frequently Asked Question:

Can I reverse, using the reversal rule, more than once?

Answer:

No, you can reverse only once. The student’s standard score will be based on his or her performance on the reversed item set. Remember that this score indicates the student’s performance in comparison to age- or grade-mates and will typically reveal what he or she cannot do. To determine what the student can do, “test the limits” by administering some of the items from an earlier item set. For example, if a student reversed to the 4th grade item set but could not answer any of the items, first calculate his or her score based on the raw score of 0. Then, administer some of the beginning items to determine if he or she can comprehend single words, phrases, or short sentences (Items 1-14).
