The Wechsler Abbreviated Scale of Intelligence (WASI; ) and the Wide Range Intelligence Test (WRIT; ) are two well-normed brief measures of general intelligence with subtests purportedly assessing verbal–crystallized abilities and nonverbal–fluid–visual abilities. With a sample of 152 children, adolescents, and adults, the present study reports meaningful convergent validity coefficients and a latent factor structure consistent with the theoretical intellectual models both tests were constructed to reflect. Consideration of the hierarchical model of intelligence tests and issues regarding test interpretation are presented.
