IQ tests are not used specifically for career testing, but are rather normally used to ascertain potential maximum mental abilities and to map out an educational or vocational track to meet this potential. There are many types of IQ tests, each with its own ranking system. There has been much research done on the validity of these tests, with many studies proving inadequate objectivity.

In addition to any uncertainties of correlation between high IQ and job performance, competing concepts of intelligence, such as emotional intelligence, social intelligence and creative intelligence, warrant call attention to the risks of and in over-extrapolating from or giving undue weight to such cognitively-focused tests. Obviously, jobs that require high-order reasoning and analytical abilities will be very suitable for those with high scores on intelligence tests. Nonetheless, although a quasi-necessary condition for many of these jobs, a high IQ is unlikely to ever be sufficient to ensure a good candidate-job match.

Needless to say, an IQ test that was never repeated may result in a score that, if lower than a given individual's actual school or work performance suggests, may tell us more about the headache, anxiety, sleepiness, blurry vision or upset stomach a child experienced on the day of testing than measure that individual's true cognitive and career potential.

An IQ test is a test purportedly designed to measure a person's intelligence. IQ stands for "intelligence quotient", which is the ratio of your "mental age" as determined by an IQ test to your chronological age. Hence an IQ of 150 means that developmentally the performance capability of the tested subject is 50% greater than the statistical norm for his or her chronological age. IQ tests are standardized tests, which mean they are administered in the same way to different people.

IQ tests have been very controversial in certain aspects because of a perceived bias in their development towards individuals in specific (sub)cultures or higher social classes than others. In addition, because they have in the past emphasized logical thinking at the expense of creative thinking and other recognizable forms of intelligence, e.g., "emotional" and social, their true usefulness has sometimes been questioned. However, since the 1970's, researchers have been working hard to eliminate any bias that has existed, often working with broader concepts.

The most widely used intelligence test for children is now the WISC-III, which stands for the third revision of the Wechsler Intelligence Scale for Children, the Stanford-Binet being a second widely used test. In the United States, the use of IQ tests as a basis of employment is banned by a United States Supreme Court decision, Griggs v. Duke Power Co., unless the employer can link the IQ test to an individual's job performance based upon a job analysis. (A job analysis describes and records the skills and other requirements necessary to perform a particular job; therefore, in order for an IQ test to be allowed as a condition of employment, the employer must show that the job performance requires some minimal level of functioning that can be measured through the IQ test.)

One area where IQ tests have been particularly helpful has been in the area of identifying those students who are mentally challenged and require special assistance at school. Early identification of such students can help them receive the aid that they need to be more successful in school and acquiring living skills then they otherwise would be.

The question of what constitutes a "high" IQ has in recent years been revisited, because of the so-called "Flynn Effect"-named after the American-born researcher James R. Flynn who discovered, that in the U.S., average IQs rose almost 14 points in the 46 years between 1932 and 1976 and have risen globally by varying, yet comparable amounts. However, this does not mean that a Mensa-level candidate tested in 1932 would be likely to have a much lower score if tested now. That's because most of the gains have been in the lower half of the IQ range.

So, the chances are that if you are an older job applicant with a very high IQ, your score has not been deflated over time.
