Scoring of the WIAT-III
Recommendations for the WIAT-III
Demonstration of the WIAT-III
Critique of the WIAT-III
- 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
- 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
- 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.
