Internationally respected for their reliability, efficiency and accuracy, the Wechsler range of assessments help measure cognitive abilities, clinical memory, achievement and ability in both children and adults.

They were originally developed by David Wechsler, PhD (1896 - 1981, pictured below), who pioneered the field of cognitive psychology, beginning with the publication of the Wechsler-Bellevue Intelligence Scale first published in 1939.

Wechsler went on to author the following highly respected tests:

Wechsler Intelligence Scale for Children (WISC)

Wechsler Individual Achievement Test (WIAT)

Wechsler Preschool and Primary Scale of Intelligence (WPPSI)

Wechsler Adult Intelligence Scale (WAIS)

Wechsler Memory Scale (WMS)

Wechsler Nonverbal Scale of Ability (WNV)

Wechsler Abbreviated Scale of Intelligence (WASI)

Test of Premorbid Functioning (TOPF)

Since Dr. Wechsler's passing in 1981, a team of expert developers have continued to evolve the Wechsler measures by creating revisions of existing measures as well as developing new scales. The result has been the continuation of innovation and precision that is based on contemporary theory and current neurocognitive research. 

The Wechsler range continues to be amongst the most widely used assessments today: a testament to its popularity and longevity.
