Demonstration of the WIAT-III

The WIAT-III is a time consuming test
It takes away critical class time for the student
It takes away critical time from the teacher or school psychologist.
1-1 administration can cause testing anxiety
It can be overwhelming for the student
Types of Scores for the WIAT-III
Standard Scores
Percentile Ranks
Normal Curve Equivalents
Age Equivalents
Growth Scale Value Scores
Reference: (Salvia, Ysseldyke, & Bolt, 2013)
Throughout the exam the administrator records the students responses in the Response Booklet.
These are the raw scores
Most of the test items are scored using 1 and 0.
1 indicates a correct answer and 0 indicates an incorrect answer
Writing portions of the exam are scored using a specific rubric.
The WIAT-III comes with a scoring assistant CD
The teacher or psychologist who administered the exam enters the raw scores into the scoring assistant program.
Once the scores are entered, all of the calculations, composite scores, and graphs are calculated automatically.
In my opinion, the WIAT-III is a very useful and effective tool.
Recommendations for the WIAT-III administrator.
Give the student breaks if needed
Do not feel obligated to finish the entire exam in one day
