Children and adults who know the results of an intelligence test may feel limited by the score. An average or below average score may cause the test taker to feel as though his potential is limited and this can have an effect on his choice of career and education later in life.
Intelligence tests may be used to distribute educational resources to children who test higher on the tests. Special classes for gifted students are considered a reward for doing well on intelligence tests and students that do not test well may be barred from resources.
Intelligence tests may be used to screen for employment and college, which limits opportunities for those who do not test well.
Intelligence tests do not test for creativity, social skills and mechanical aptitude, according to the Encyclopedia of Mental Disorders. The intelligence test does not allow for any answers to the questions that display an unconventional way of thinking, according to the University of North Carolina at Chapel Hill.
The IQ test only results in a single number as an overall score for intelligence. The test does not display accurately where a particular person's strengths lie. Two people can have the same score with very different strengths and weaknesses.
Intelligence tests do have some success predicting academic success, but it is very limited in predicting vocational success. For those who do not score well, the test may prove to be a hindrance to future success as well.
