Intelligence Test

Intelligence Test

IQ test is an assessment that measures a range of cognitive abilities and provides a score that is intended to serve as a measure of an individual's intellectual abilities and potential. IQ tests are among the most administered psychological tests.

To understand what these scores really mean, it is essential to look at exactly how these test scores are calculated. Today, many IQ tests are standardized, and scores are derived by comparing individual performance against the norm for people in that age group.

Uses of IQ Tests

IQ tests can be used for a wide range of purposes, including:

• Educational assessment and placement
• Assessment and diagnosis of intellectual disability
• Cognitive research
• Job candidate evaluation
• Assessing cognitive abilities including memory, speed, and attention

Impact of IQ Testing

IQ can have an impact on different areas of life, including school and work. High scores are often associated with higher achievement in school, while lower scores may be linked to some form of intellectual disability.

Intelligence test scores typically follow what is known as a normal distribution, or a bell-shaped curve in which most scores lie near or around the average IQ test score. For example, the majority of scores (about 68%) on the Wechsler IQ tests tend to lie between plus 15 or minus 15 points from the average score of 100.
