What Is An IQ Test Free? History of IQ Testing

IQ (intelligence quotient) is a measurement of an individual’s cognitive ability. It indicates where an individual ranks in a large population. Normally, IQ tests assess logical reasoning, language skills, problem-solving skills, mathematical aptitude, and spatial recognition.

IQ Test Free is a standardized assessment available at no cost, aimed at evaluating an individual's cognitive abilities and intellectual potential. Although it is designed to be less complex compared to costly, professionally administered IQ tests, it endeavors to offer accurate results that are equivalent to those tests. Our free IQ test offers a logical and scientifically validated test with trustworthy results. Basically, the test is designed to adapt to the individual’s demand of unveiling their IQ potential as well as an IQ self-understanding journey.

In the early 1900s, Alfred Binet created the Stanford-Binet test, which was the first attempt to measure intelligence. The test was designed to identify children who might have learning difficulties and require special education. Since then, cognitive tests have been used as a way of assessing students' abilities and potential. In the human resource field, these tests helped to categorize and assign staff to roles that matched their strengths and weaknesses.
