Life Psychologists provide IQ and cognitive ability testing for adults and children (over 7 years).

An IQ test or cognitive assessment evaluates how your brain functions and can help you identify:

  • Giftedness
  • Intellectual/cognitive ability
  • Learning difficulties
  • Memory functioning
  • Attention and concentration 
  • Executive function 
IQ Testing


An Intelligence Quotient (IQ) test is an assessment that measures a range of cognitive abilities and provides a score that is intended to serve as a measure of an individual’s intellectual abilities and potential.

An I.Q. score is essentially a standardised way of comparing intellectual ability with people of the same age.

IQ testing can be used for a wide range of purposes including:

  • Assessing cognitive abilities including memory, speed, learning, and attention
  • Measuring giftedness
  • Educational assessment and placement
  • Assessment and diagnosis of intellectual disability
  • Cognitive research
  • Job candidate evaluation

How can IQ testing help for children?

  • To assess gifted children in order to provide appropriate and stimulating learning environments, e.g. opportunity class (OC), gifted and talented program (GAP), MENSA registration, and/or selective high school.
  • To test for school readiness.
  • To provide intervention programs for children with specialised needs.
  • To screen for any cognitive deficits.
  • To assess for eligibility for funding e.g. NDIS.
  • To understand a child’s learning profile or preferred learning style.
  • To assess for learning disorders (such as reading, mathematics or writing disorders, including dyslexia).
  • To identify developmental delays and provide appropriate interventions for psychoeducational disorders or problems as early in a child’s life as possible.
  • To understand uncharacteristic behaviours and/ or emotional issues that are presenting at either home or school.

Impact of IQ Testing Scores

Your IQ can have an impact on different areas of your life including school and work. High scores are often associated with higher achievement in school, while lower scores may be linked to some form of intellectual disability.

The following is a rough breakdown of various IQ score ranges. Some tests present scores differently and with differing interpretations of what those scores might mean.

IQ Classifications

IQ LevelDescriptive Classification
130+Very Superior
120 to 129Superior
110 to 119High Average
90 to 109Average
80 to 89Low Average
70 to 79Borderline
69 & belowIntellectual Disability
These classifications come from the Wechsler series of IQ tests for children and adults.

Intelligence test scores typically follow what is known as a normal distribution, a bell-shaped curve in which the majority of scores lie near or around the average score. For example, the majority of scores (about 68%) on the Wechsler series of intelligence tests tend to lie between plus 15 or minus 15 points from the average score of 100.

This means that approximately 68% of people who take this test will score somewhere between 85 and 115. As you look further toward the extreme ends of the distribution, scores tend to become less common.


Life Psychologists administer the gold-standard range of IQ tests including:

Wechsler Intelligence Scale for Children (WISC)

The WISC is a comprehensive measure of a child’s intellectual ability. It can be used among a battery of other tests to assess and identify learning disabilities, strengths and weaknesses as well as giftedness.

Test age range: 6 -16 years

Structure:  4 sessions
Session 1 – Intake Interview 1-1.5 hours
Session 2 – Assessment – 2-3 hours
Session 3 – Report and Feedback
Session 4 – Recommendations and future planning

$950 (incl. testing & report)

Wechsler Adult Intelligence Scale (WAIS)

The WAIS is a comprehensive measure of an adult’s cognitive ability. This assessment can be used to examine the relationship between intellectual functioning and memory.

Test age range: 16 – 89 years

Structure:  4 sessions
Session 1 – Intake Interview 1-1.5 hours
Session 2 – Assessment – 2-3 hours
Session 3 – Report and Feedback
Session 4 – Recommendations and future planning.
