IQ tests are indicators of a person's mental ability in relation to others around the same age. An individual has many mental abilities; some are measured with a high degree of accuracy and can reliably predict his or her academic and financial success.
Intelligence quotient scores are used in differing contexts-some for special needs and some for educational achievement. Others predict job performance and income. The average scores for these tests in many cultures have risen at a rate of three points per decade. It is a debatable whether these changes reflect mental ability.

IQ tests are indicators of a person's mental ability in relation to others around the same age. An individual has many mental abilities; some are measured with a high degree of accuracy and can reliably predict his or her academic and financial success.
Intelligence quotient scores are used in differing contexts-some for special needs and some for educational achievement. Others predict job performance and income. The average scores for these tests in many cultures have risen at a rate of three points per decade. It is a debatable whether these changes reflect mental ability.
Intelligence quotient tests are constructed by setting an average score within a group to 100 and the standard deviation to 15. Almost all modern tests use the assignment of 15 points to a standard deviation. Previously, tests were made with two standard deviations to the average, which would set 95 percent of people ranging between 70 and 130 intelligence quotient points.
It is impossible to determine exactly what intelligence is construed of, which makes the accuracy of intelligence testing very debatable. It is likely that the scores reflect a specific type of intelligence and testing different contexts might be a good idea.
