Weschler Abbreviated Scale of Intelligence (WASI)

The WASI (Psychological Corporation, 1999) is a brief scale of intelligence that estimates full scale IQ using two or four subtests and has been normed for ages 6 through 89. This study uses the two-subtest format of Vocabulary and Matrix Reasoning. The WASI two-subtest format FSIQ correlates .81 and .87 respectively with the Wechsler Intelligence Scale for Children-III and Wechsler Adult Intelligence Scale-III full scale IQs.
