Many IQ tests are used today. Whether they measure actual intelligence or simply certain abilities is controversial. IQ tests measure a specific functioning ability and may not accurately assess a person's talents or future potential. Results of any intelligence test may be culturally biased.
The more widely used tests include:
- Wechsler Preschool and Primary Scale of Intelligence
- Stanford-Binet Intelligence Scales
- Differential Ability Scales
- Kaufman Assessment Battery for Children.
Functioning abilities that are measured by these tests include language, mathematical, analytical, spatial (for example, reading a map), among others. Each test has its own scoring system.
In general, IQ tests are only one way to measure how well a person functions. Other factors, such as genetics and environment, should be considered.
