Choose well-recognized IQ tests that undergo rigorous development and are reviewed regularly. Validity and reliability are important factors, and tests should be empirically confirmed to measure general intelligence consistently. Consult licensed psychologists or psychology journals for advice, and avoid internet tests. Accurate IQ tests can be expensive but are worth the investment.
Individuals seeking to obtain the most accurate intelligence quotient (IQ) tests should choose those that are well recognized by the academic community and have undergone a rigorous development process. These standardized tests of general intelligence are typically checked and balanced against a sample of thousands of test takers before finalization. Researching psychological journals or consulting with licensed psychologists can help determine which of the available options are the most accurate intelligence tests. Experts generally advise against obtaining exams over the Internet, as they tend not to meet strict test development standards.
Accurate IQ tests are developed in accordance with several important test design principles. Validity and reliability are two of the most important factors in developing an IQ test; validity refers to whether or not the answers to each question are correct, and reliability refers to the consistency of the results when the test is taken multiple times. Based on these two principles, individuals should take IQ tests that are empirically confirmed to measure general intelligence on a consistent basis.
Those who want to get accurate intelligence tests should also choose exams that are reviewed regularly. Some elements of the test may become obsolete, depending on sociocultural changes, and need to be replaced accordingly. The validity and reliability of regularly updated tests tend to be improved as a result of the reviews. Any type of development in accurate IQ tests, whether in creation or revision, should be tested for accuracy of results, validity, and reliability on large-scale samples.
Information about developing and reviewing accurate IQ tests can often be found in psychology journals. If people are comfortable with scientific language, they can conduct research on which intelligence tests to choose by reading their development directly from publications. If, however, the journals prove too difficult to understand, people looking for accurate intelligence tests can consult a licensed psychologist for advice on which exams to choose. Measures such as the Stanford-Binet Intelligence Scales are among the most recommended.
The intelligence tests available on the Internet are generally considered poor choices, as they tend to lack the level of development and revision that more standardized tests require. These tests are more geared towards casual use and may have questions based more on popular psychology than proven empirical evidence. Accurate IQ tests are usually purchased by contacting the institution that holds the test’s license; additional copies are usually available upon request. While these can be very expensive, especially compared to free internet tests, the amount of work put into their development and high level of accuracy make them a much better choice.
