How is the WIAT Test Scored?
WIAT test scoring (Wechsler Individual Achievement Test-Third Edition) is based on several derivations of status scores and growth scores.
They are as follows:
- Status Scores
- Standard Score
- Percentile Rank
- Normal Curve Equivalent
- Stanines
- Growth Scores
- Grade Equivalent
- Age Equivalent
- Growth Scale Values
For standard scores, each number given shows the level at which your child is performing.
Very superior scores are scores over 130.
Superior scores range from 120-129.
High Average scores range from 110-119.
Average scores ranger from 90-109.
Low scores range from 80-89.
Borderline scores range from 70-79.
Extremely Low scores are scores under 69.
The administrators then use these scores to interpret performance by noting and comparing the following, noting the pattern of strengths and weaknesses:
- Growth Scale Values
- Grade-Based and Age-Based Scores
- Composite Scores
- Score Differences
- Statistical Significance of Score Differences
- – Frequency of Score Differences
- – Qualitative Evaluation of Subtest Component Score Differences
- Out-of-Level Item Set Performance

Hi Katia,
For score interpretation on the WIAT I would recommend reaching out to the psychologist that administered the test.
All the best,
Mayra
