Introduction
Intelligence tests exist in many forms, including types that use single or multiple types of questions or items. Most of the tests applied in evaluating intelligence give both the individual subtest scores, as well as the general score. However, regardless of the design of the intelligence tests, all of them make trials to measure similar general intelligence. Furthermore, some of the tests are selected because they are predictive and can be used to determine future intellectual development. For instance, they can be used to predict future developments in the educational achievement of an individual. In the real-life situation, intelligence quotient determined by the tests is also used as predictor of such aspects as job performance, as well as socioeconomic advancement. Intelligence tests can be administered to groups or individuals, although the individual ones are the most popular.
Methods of intelligence testing
Stanford-Binet Intelligence Test
Wechsler Intelligence Scale for Children (WISC)
Wechsler Adult Intelligence Scale (WAIS)
Differences between the methods
Stanford-Binet Intelligence Test
Age range = 2 – 90+
Description: A full scale score update is given. The test evaluates knowledge, fluid reasoning, working memory, visual-spatial processing, and quantitative reasoning. The test also measures the ability to form a comparison between non- verbal and verbal performance (Kaufman, 2009).

Wechsler Intelligence Scale for Children
Age range covered = 6 – 11
Description: The test gives a full scale score for verbal comprehension, perpetual reasoning, working memory, as well as the processing speed (Fletcher & Hattie, 2011) .
Wechsler Adult Intelligence Scale
Age range covered = 16 – 89
Description: It is an intelligence assessment of older children, as well as adults. The test provides a full score of verbal performance (Stern, 2018). It also provides scores for perceptual organization, verbal comprehension, as well as processing speed.
Conclusion
There are different methods of intelligence testing. The most common methods include Stanford-Binet Intelligence Test, Wechsler Intelligence Scale for Children (WISC), and Wechsler Adult Intelligence Scale (WAIS).
