    Q & A from the KTEA-3 and WIAT-III Dyslexia Index scores webinars

    Where do I access these Dyslexia Index scores?

    In print, in Q-global, and soon-to-be in Q-interactive!

    • KTEA-3 Dyslexia Index Scores Manual (Manual Scoring) 015801524X
    • KTEA-3 Dyslexia Index Scores Manual on Q-global 0150023189
    • WIAT-III Dyslexia Index Scores Manual (Manual Scoring) 0158015258
    • WIAT-III Dyslexia Index Scores Manual on Q-global 0150023197

    Is the information in these new manuals similar to the Essentials book?

    The original tables were first published in the Wiley Essentials of KTEA-3 and WIAT-III Assessment book, yes. However, these new manuals are expanded in content (with a wider age range in the case of WIAT-III), have the necessary forms, directly include scoring and significant interpretive information related to risk and recommendation language.

    Is the score form included when I order protocols?

    The score form is included in the new manuals - you may reproduce!

    If we use either the KTEA-3 or the WIAT-III comprehensive tests now, can we just use the relevant subtests needed for these scores, or do we need other content?

    If you have the current KTEA-3 or WIAT-III complete kits, you have everything you need except the new Dyslexia Index score manual--choose print or Q-global version.

    Can I use the raw data from the Q-interactive administration to score using one of these new manuals?

    Yes, you can use an existing KTEA-3 or WIAT-III administration with the new Dyslexia Index score manual.

    Will Q-global score this currently? 

    We are working on approvals for integrating the Dyslexia Index scores into the Q-global scoring and reporting, but that functionality is not available at this time.

    How do you get the computation form?

    It's included in the new manual.

    Will the WIAT-III Dyslexia Index score give us a different score than typical scoring on the WIAT-III? 

    Yes. It will provide a new score and that was not available before in the WIAT-III test. This score can be used on its own as a screener, or it can be used as part of the comprehensive evaluation with a full administration of KTEA-3 or WIAT-III.
