Shipley-2

The Shipley-2 can be administered to individuals or groups in just 20 to 25 minutes, and scored in 5 minutes. The test produces standard scores for the scales administered, as well as percentiles, age-equivalents, and confidence intervals. It also provides a Composite score, which is formed by combining the Vocabulary score with either the Abstraction score (Composite A) or the Block Patterns score (Composite B). Composites A and B are interpreted very similarly. Both are standard scores that reflect overall cognitive ability.

The Shipley-2 provides a useful Impairment Index. Calculated only for adults, it represents the discrepancy between vocabulary and abstract thinking.

Norms are based on a sample of 2,826 individuals representative of the U.S. population in regard to ethnicity, gender, and educational level. They are presented separately for children aged 7 to 19 and adults aged 17 to 89. The Shipley-2 is also and stratified by age.
