As a result, Wechsler devised a new test during the 1930s, known as the Wechsler-Bellevue Intelligence Scales.
The test was later revised and became known as the Wechsler Adult Intelligence Scale, or WAIS.
The goal of his original test was to help identify children who needed specialized help in school.

One benefit of this approach is that the pattern of scores can also provide useful information.
On the current version of the WAIS,test scoresthat fall between 90 and 110 are consideredaverageintelligence.
Many other intelligence tests later adopted Wechsler’s method, including the modern version of the Stanford-Binet.
Versions of the WAIS
There have been four different versions of the WAIS over the years.
Additionally, the WAIS-5 test provides five major index scores.

The WAIS surpassed the Stanford-Binet in use during the 1960s.
Today, it is the most frequently used intelligence test worldwide for both adolescents and adults.
They can utilize the test to see what areas of the brain have been affected and determine cognitive function.
