Psychometric Testing

Intelligence testing is a method used by psychologists to measure an individual's intellectual capabilities. Intellectual assessment is a good indicator of a individual's academic potential. The results of an IQ test rank an individual against a very large sample of people the same age.

We use the Wechsler Intelligence Scale for Children, Fourth Edition, Australian Standardisation (WISC-V). This is an individually administered instrument for assessing the cognitive ability of children aged 6 years to 16 years. 

To assess older adolescents and adults, we use the Wechsler Adult Intelligence Scale, Fourth Edition, Australian Standardisation (WAIS-IV). This battery was designed to parallel the WISC for those aged 16 years to 90 years.

The WISC-V and WAIS-IV are some of the most reliable and valid IQ testing instruments available and are the most widely used measures of IQ. Both batteries provide scores that represent intellectual functioning in four specified cognitive domains: Verbal Comprehension, Perceptual Reasoning, Processing Speed and Working Memory. The WISC-V and WAIS-IV also provide a Full Scale IQ score measuring general intellectual ability. During the testing session the individual is asked to solve problems and puzzles and to answer a range of questions. Most people enjoy the testing session as it is an engaging process involving novel and fun tasks.
