What is one advantage of the Wechsler Scales?
An immediate benefit of the Wechsler approach to IQ testing was the large number of reliable and valid scores yielded by his tests – three IQs and an array of a dozen or so scaled scores on separate subtests. The Full Scale IQ provides a global measure of intelligence (as was provided by the Stanford-Binet).
