Product Details

Benefits

  • Screen for dyslexia with stimulus materials you may already own with new Dyslexia Index Scores
  • Identify student academic abilities, make educational placement decisions, diagnose specific learning disability, design instructional objectives, and plan interventions.
  • Measure eight areas of achievement to assist in the identification and classification of learning disabilities.
  • Focus on reading goals and objectives with the Early Reading Skills subtests.
  • Evaluate patterns of strengths and weaknesses to identify learning disabilities.

Features

  • Subtests include: Enhanced Listening Comprehension, Oral Expression, Written Expression subtests, Enhanced Reading Comprehension, Oral Reading (new), Math Fluency (new), and Early Reading Skills (new).
  • Dyslexia Index Scores can be used for screening, inclusion in a comprehensive assessment battery, and as a tool for research.
  • Improved scoring rules in response to scoring studies, theoretical reviews by expert researchers, and usability reviews by teachers and clinicians.
  • Enhanced scoring software and interactive scoring guide in every kit.
  • Updated Canadian norms for PreK through Grade 12 as well as for individuals ages 4:0–50:11; the adult norm sample from 20–50:11 years is also linked to the WAIS–IV-CDN norm sample.

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.
