What is a test of IQ? What kinds of IQ testing are there?


IQ tests, which are administered in a variety of formats, are more formally known as “intellectual quotient” tests. They are useful for diagnosing intellectual impairments as well as measuring the intellectual capacity of an individual. If you are thinking about getting your IQ tested, the first person you should talk to is your primary care physician.

A Brief Overview of IQ Testing

Alfred Binet, a psychologist from France, is credited with developing the first IQ test in the early 1900s. On the other hand, the work of Henry Herbert Goddard is the foundation of contemporary intelligence testing in the United States. Goddard was a psychologist who attended Clark University and received his Ph.D. in psychology there in the year 1899. He translated the Binet test from its original language, which was French, into English. This exam was given to schoolchildren in the United States to evaluate their fundamental intellectual functioning and to support mental health diagnoses.

Goddard is still regarded as a contentious character in the annals of psychological history. This is a result of his contention that individuals who have low IQs should not have children. We can give thanks that such perspectives are becoming increasingly rare in today’s culture. Today, there are a great number of IQ tests that may be used for a variety of objectives; nevertheless, the majority of these tests are utilized to assist in the diagnosis of learning difficulties.

Varieties of Intelligence Quotient Tests

Numerous more tests have been developed by psychologists in the time since Goddard’s contentious Binet tests. Most of them are geared toward children who are in elementary school, although some can also be used by adults.

The following are the most popular types of IQ tests:

  • The Stanford-Binet Measure of Intelligence
  • Differential Ability Scales for Nonverbal Intelligence (Universal Nonverbal Intelligence Scales)
  • The Individual Achievement Exam at Peabody High School
  • Individual Achievement on the Wechsler Test
  • The Wechsler Intelligence Scale
  • Cognitive Abilities Diagnosed Using the Woodcock-Johnson III Tests

The results of an intelligence test

The National Institute of Child Health and Human Development is cited as the reliable source that found that 85 percent of children with intellectual disabilities had IQ scores that fall between 55 and 70. It is generally agreed that a score of 100 represents the norm.

Excellent Results

A high intellect level is often linked with having an IQ score that is greater than 100. Intelligence levels exceeding 130 are considered extremely high. In spite of this, these results are rather normal. A high score does not always indicate that the individual is exceptionally “clever,” but rather that they have a great deal of potential.

Poor Performance:

Someone who receives a score of less than 100 is deemed to have an intelligence that is “below average.” Scores below 70 are typically a reason for worry, especially when they are extremely low. It’s possible that they point to an underlying learning problem.

An intelligence test is often the initial step in the diagnostic process for intellectual problems. Your child’s physician may also request the following tests if the child’s score is especially low:

Examination of Adaptive Abilities

Screenings performed throughout pregnancy might help detect signs of possible intellectual impairments in unborn children. This is especially true for moms who are 35 years old or older, as well as for women who have used drugs or alcohol while pregnant. Your physician may recommend an iq test for your young child later on if he or she finds any signs of possible problems during this screening.

Where to Find an Intelligence Quotient Test

Measures of intelligence are only one factor. Many households still lack access to these evaluations. Even though they’re available, not all public schools use them. Some households may not have ready access to medical or mental health professionals who can conduct the evaluation. This can prevent children from getting the therapy they need in their formative years when early detection is important.

By taking a real iq test, you may evaluate your cognitive abilities.

Although IQ tests are easily accessible online, they should not be used in place of a professional medical evaluation. Do not wait for a doctor to give a test for intellectual impairment if you are concerned about a family member. Investigate potential pre-release testing opportunities.
