The Wide Range Intelligence Test (WRIT)

By Inderbir Kaur Sandhu, Ph.D


Q: How is the scoring and interpretation of Wide Range Intelligence Test?

A: I am not very familiar with this test but I will attempt to advise. The Wide Range Intelligence Test (WRIT) consists of a battery of four tests of cognitive ability that is; vocabulary (a traditional word definition task), verbal analogies (a fast-paced verbal-reasoning task), visual matrices (a traditional matrix task assessing visual-spatial reasoning and abstract visual-perceptual relationships), and diamonds (a spatial constructional task using diamond-shaped chips to duplicate two- and three-dimensional figures). Two of the subtests assess verbal-crystallized abilities (vocabulary and verbal analogies), which are more dependent on acquired knowledge, and two measure nonverbal-fluid abilities (visual matrices and diamond), which are environmentally and culturally reduced This is an individually administered test that can be completed in 20-30 minutes and yields a Verbal Reasoning IQ, a Visual Reasoning IQ, and a Composite IQ. It covers all age ranges from 4 to 85, providing measures of crystallized and fluid intelligence.

The scoring should be similar with other intelligence tests. As with other tests, there are raw scores (the standard scores), percentile (percentage of score) and performance description (low average – high average). To interpret the scores, you would first need to examine all of the subset standard scores to determine strengths or weaknesses. E.g., if a performance description indicates “very low”, it would need significant attention. Based on the four subsets, there would be a verbal and visual score, which is a composite score. Thus, these scores would be affected by extreme scores, which affect the final IQ score (General).

Extreme low scores may indicate a learning disability. The WRIT has been used to look for extreme scores that indicate dyslexia. In addition, WRIT was co-normed with the Wide Range Achievement Test (WRAT) to help psychologists make valid comparisons between intellectual and academic functioning.

Hope that helps.
