Intelligent Quotient is a very old term used by Psychologists. Did you know it was First discovered 110 years ago, way back in 1912? Since then, IQ has been an essential aspect of understanding human intelligence.

The Intelligence Quotient is used as a tool to measure the ability of an individual to solve problems through logical reasoning. It is used to understand cognitive and academic intelligence. This ability is directly proportional to the child's intelligence, and IQ is used to measure this. In simple words, few children of the same age are given a minor annoyance to solve, and then IQ can be calculated based on how much time the child took and how accurate his answer is.

Let us understand IQ in detail.


IQ is a scoring method. Here the ability of a person is calculated based on age. Intelligence is directly related to the age of the person. When we go for an IQ test, some problems and activities are given to the individual. They are categorized based on difficulty level. So easy issues have a lower score, and as the difficulty increases, the score for that problem also increases. At the end of the session, a total score is derived based on appropriate answers. These scores are used for understanding your IQ based on your age. The IQ scale is very scientific as it results from detailed research and experiments.

Let us understand how to calculate IQ with an easy example!


Scientists believe that every individual has a mental age and a physical age. So biological age is easily calculated with the date of birth, and mental age is calculated with the help of some intelligence tests. IQ is calculated by taking the mental age to biological age and then multiplying that by 100.

Let's understand this with an example:

Suppose a 15-year-old child comes to take a test. After completing the test, he gets an average score of 18 points, so his mental age is 18, and his physical age is 15

18/15 * 100 = 120 

So the IQ of the child is 120  

IQ score generally ranges between 70-and 130. Generally, the average IQ score is 100. So a person scoring more than 100 has a higher IQ than a person achieving a little less. 

How applicable is the IQ test?


IQ test results are a way of understanding the mental intelligence of an individual. So it is extensively considered in education sectors, placement sectors and even defence sectors. Some challenging job positions ask for an IQ test report. Educational Institutions providing advanced courses also ask for an IQ test report. In some cases, they conduct an IQ test to understand an individual's mental ability.

The link between IQ and Career Counseling Centers:

An IQ test is one of the initial steps in understanding an individual's intellectual power and intelligence issues. Parents realize that the child lacks behind in some subjects and finds it difficult to cope. At times, parents feel that the child has concentration problems. They understand the child's difficulty but are unable to understand the problem. So the IQ test serves as a diagnostic test. For example, parents now take their children to the doctor for stomach pain, and the doctor suggests some difficulties to understand the cause based on the report; the doctor prescribes medicines for well being.

Apply the same logic to mental health. Career counsellors are doctors, and the IQ test is the medium to understand the root cause of the problem. Once the test reports come, the career counsellor guides the child through the path of overcoming his difficulties for academic excellence. This is a crucial stage in career counselling. Parents feel that career counselling is all about getting to know career options but in reality, established Career Counselling Centers like BRAINWONDERS work to improve the broader picture. They conduct an IQ test to understand the mental and cognitive capabilities of the child. They try to implement these results for present and future growth. Based on the reports, they will devise a career strategy for the child, but along with that, they also work on current issues. They will start by addressing the current problems and suggest corrective measures. They will minutely explain those areas where the child needs guidance. So an IQ test is beneficial right from the beginning.
