Intelligence is an important psychological construct that refers to an individual’s general capacity to learn from experience, understand complex ideas, reason effectively, solve problems, adapt to new situations, and use knowledge appropriately. In behavioural sciences, assessment of intelligence is concerned with understanding these cognitive abilities in a systematic and objective manner. Intelligence assessment helps psychologists, teachers, counsellors, clinicians, and researchers understand individual differences in mental abilities and use this information for educational, occupational, clinical, and social purposes. The assessment of intelligence begins with a clear understanding of what is meant by intelligence. Different psychologists have explained intelligence in different ways. Spearman proposed the concept of general intelligence or “g”, suggesting that performance on different intellectual tasks is influenced by a common general ability. Thurstone emphasized several primary mental abilities, such as verbal comprehension, word fluency, number ability, spatial visualization, associative memory, perceptual speed, and reasoning. Gardner proposed multiple intelligences, including linguistic, logical-mathematical, spatial, bodily-kinaesthetic, musical, interpersonal, intrapersonal, and naturalistic abilities. Although theories differ, intelligence assessment generally attempts to measure an individual’s cognitive functioning through standardized procedures. One of the major methods of assessing intelligence is the use of standardized intelligence tests. These tests consist of carefully designed tasks that measure different aspects of intellectual functioning. Standardization means that the test is administered, scored, and interpreted according to established procedures. The performance of an individual is compared with the performance of a relevant normative group. Standardized testing makes it possible to identify whether an individual's performance is below, average, or above the expected level for people of a similar age or educational background. Intelligence tests may be classified into individual and group tests. Individual intelligence tests are administered to one person at a time by a trained examiner. They allow the examiner to observe the individual’s behaviour, attention, motivation, problem-solving strategies, and response patterns in greater detail. Examples include the Stanford-Binet Intelligence Scales and the Wechsler scales. Group intelligence
