Wechsler Intelligence Scale for Children

The Wechsler Intelligence Scale for Children (WISC), developed by David Wechsler, is an individually administered intelligence test for children between the ages of 6 and 16. The Fifth Edition (WISC-V; Wechsler, 2014) is the most recent version.

The WISC-V generates a Full Scale IQ (formerly known as an intelligence quotient or IQ score) that represents a child’s general intellectual ability. The indices generated represent a child’s abilities in discrete cognitive domains.

What does the testing entail?

The test will be a one-to-one session with Dr Sandhu. Your child will do a series of verbal and written tests under her observation and supervision. Dr Sandhu will administer 7-10 primary sub-tests depending on the child’s performance. While only 7 tests are required for a full scale IQ, Dr Sandhu usually administers 10 to generate a more comprehensive picture of your child’s intellectual profile. Your child is allowed to take a break at any time (apart from timed tests).

What will I understand/derive from the test?

You will receive an 8-page written report and the following scores will be provided.

A Composite Score (from seven of the 10 primary subsets) that represents a child’s overall intellectual ability (FSIQ).

Five Primary Index Scores that measure the following areas of cognitive functioning: Verbal Comprehension Index (VCI), Visual-Spatial Index (VSI), Fluid Reasoning Index (FRI), Working Memory Index (WMI), and the Processing Speed Index (PSI).

Three (of five) Ancillary Index Scores are also provided: The Quantitative Reasoning Index (QRI); Auditory Working Memory Index (AWMI); Nonverbal Index (NVI); General Ability Index (GAI); and the Cognitive Proficiency Index (CPI).

How long is the test? 

1.5 to 2 hours

In her field of speciality (Gifted Education), Dr Sandhu has served in various capacities in institutions across the world.

Dr Sandhu specialises in bringing out the potential of young children and gifted individuals. ​

We help parents understand their gifted children better through specialised assessments and provide advice and training on how they can help their children in their learning journey. Families will benefit from an enhanced understanding of the emotional and intellectual needs of their bright children and learn how best to manage them through a customised training programme.


Dr Sandhu offers individual and family counselling on social, emotional, and educational issues of gifted and twice-exceptional children. This may include advocacy assistance with school administrators and teachers.

It is crucial for parents and educators to understand that while there are many methods of counselling, there are few specific modalities designed for counselling gifted children. This is due to their exceptional nature attributed to giftedness and their distinct characteristics. Conventional approaches to counselling may not suffice when dealing with gifted individuals.

Dr Sandhu also offers general counselling for individuals, family and students.
