Psychometric Testing (IQ Assessments)

Wechsler Intelligence Scale for Adults (WAIS)

Designed to measure intelligence in adults and older adolescents by psychologist Dr David Wechsler, the WAIS is in its fourth version which was published by Pearson in 2008. The test contains 10 sub-tests and 5 supplemental tests. The core tests comprise the entire IQ scale, and determines the capacity of a person to act and think purposefully and rationally and to deal effectively with his or her environment.

The WAIS is appropriate for adults and adolescents ranging from 16 to 90 years of age.It takes around 90 minutes to complete the assessment.

Wechsler Intelligence Scale for Children (WISC)

Testing to determine if your child is “intelligent enough”, or finding out your child's “'IQ score” as a matter of curiosity, are not grounds to send your child for an intelligence assessment. Results from subsequent assessments may lead to an inaccurate reflection of your child's cognitive abilities and nullify subsequent test results, especially if your child is re-tested on the same instrument.

However, children between the age of 6 and 16 may be sent for psychometric testing if parents require additional information about their child's educational or psycho-social functioning. For example, intelligence tests may help to diagnose any learning disabilities your child may face. An IQ assessment may also be necessary for entry to special needs school in Singapore.

We administer the Wechsler intelligence Scale for Children – Fifth Edition (WISC-V), which assesses a child's cognitive abilities including concept formation, visual spatial processing, inductive reasoning, working memory, and speed of information processing. It can be completed without any reading or writing, and takes 65 to 80 minutes to complete the assessment. Read more about the WISC here.

The overall IQ score is not as important as understanding the profile of your child's cognitive strengths and weaknesses on a holistic basis. Only through a good understanding of your child's strengths and weaknesses will a parent be able to direct appropriate resources to helping him or her. For this reason, IQ assessments are always conducted and interpreted by an experienced psychologist.
