Frequently Asked Questions

Here we will resolve some common doubts and problems that users of IQ Certify have.

IQ, short for "Intelligence Quotient", is a rating considered for evaluating one or more aspects of human intelligence. Human intelligence encompasses various types of knowledge, skills, and abilities that underlie our ability to effectively navigate and understand the world around us, as well as to solve a wide range of problems. No single score can completely capture all aspects of human intelligence; however, scientists have developed very effective methods for accurately and precisely estimating fundamental aspects of human intelligence, such as a person's ability to reason and think logically, process sensory information, solve mathematical problems, read and understand texts, etc. Numerous research studies have also demonstrated that IQ measures can be good indicators of success in academic and work environments, and useful for diagnosing learning disabilities.

Human intelligence is, by its very nature, an abstract concept and, therefore, can only be defined in relative terms. That is, there is no universally accepted definition or absolute standard for human intelligence. IQ scores, therefore, are designed to provide a means of comparing an individual's mental abilities relative to the general population, or a specific segment of the general population (for example, a person's age group). Typically, IQ scores are standardized in such a way that a score of 100 represents the average score for a population, and approximately two-thirds of the entire population receive scores ranging from 85 to 115. The remaining third of the population have IQs that are well above or below the population average.

It is important to emphasize that, although IQ scores can provide a good measure of an individual's intellectual abilities, they are far from perfect. For example, a person may be distracted or tired while taking an IQ test and receive scores that underestimate their true abilities. Traditional IQ scores may also not be good indicators of social and emotional learning skills, such as how well individuals perform in social environments or manage their emotions.

IQ is generally measured through tests designed to assess one or more aspects of a person's intelligence. These aspects may include mental abilities such as reasoning and logical thinking, visuospatial reasoning, short-term or working memory, quantitative reasoning, or verbal knowledge and reasoning.

IQ tests can be administered via a computer, in pencil and paper formats, or in person by a professional psychologist, and can take anywhere from a few minutes to several hours to complete, depending on the types of knowledge, skills, and abilities being assessed.

The IQ Certify Intelligence Test is conducted exclusively online and is currently designed to measure key aspects of a person's general "fluid intelligence". Fluid Intelligence refers to a broad set of mental abilities that require little or no prior learning or experience. These include solving abstract reasoning problems or recognizing patterns or logical relationships between shapes, numbers, or letters. They are termed "fluid" skills in the sense that they are considered to "flow into" or support a wide range of other intellectual abilities. People who have a high level of fluid intelligence tend to perform well in academic and work environments, especially in conditions characterized by uncertainty, ambiguity, complexity, and time pressure.

When you complete the IQ Certify test, we analyze your answers and compare them with those of other users in our database to standardize them on a scale that allows you to compare your performance with that of the rest of the users who took the test under the same conditions of age or education.

At IQ Certify, your results can be compared with those of people in the same age range from all over the world who have already completed our test. Like most IQ tests, the average IQ score at IQ Certify is generally 100. According to our data and that of many studies, approximately 66% of users receive scores ranging from 85 to 115 IQ points.

One-third of the population has an IQ that is above 115 or below 85. Below we will see a table with the average IQs and their percentile ranges in the population.

IQ Scale Percentile Range
+130 99
116 – 130 68 – 98
101 – 115 51 – 67
100 50
85 – 99 33 – 49
70 – 84 2 – 32
-70 1

The intelligence quotient generally has a genetic factor but can also be trained and developed. If you perform various tests to strengthen your brain, you can increase your intelligence quotient. No matter your age, intelligence quotient tests are generally based on logic, and we can train our brain.
