IQ testing is a well-established method for assessing cognitive abilities and mental functioning. 

In the field of psychology, IQ tests are also used to assess cognitive changes over time, track intellectual development in children, and provide valuable data for research on various topics related to human intelligence. They can be instrumental in identifying potential areas of strength and weakness in an individual’s cognitive profile, helping educators and psychologists tailor interventions and support accordingly.

It’s worth emphasizing that IQ scores are not fixed but can change over a person’s lifetime due to various factors, including life experiences, and environmental influences. As such, IQ tests should be considered as just one component of a comprehensive assessment of an individual’s intellectual abilities, and their interpretation should always take into account the broader context of an individual’s background and circumstances.
