IQ score

Parents tend to search “What is the average IQ for a 13-year-old?” or “What is the average IQ for a 10-year-old?”. The key point to remember is that all tests are designed to get an average score of 100 for people of all ages.

Current average IQ scores vary between 85 and 115 (about 68% of people). The remaining 32% of people have either a very low IQ (below 70%) or a very high IQ (above 130).

However, according to a study published by NCBI (National Center for Biotechnology Information), the average IQ score increases by about 13 points every decade. Therefore, IQ tests are redesigned to achieve 100 points as an average.

Below is a table of the IQ score classification of the Stanford-Binet Intelligence Scale:

IQ Score Correspondence
145 - 160 Very gifted or highly advanced
130 - 144 Gifted or very advanced
120 - 129 Superior
110 - 119 High average
90 - 109 Average
80 - 89 Low average
70 - 79 Borderline impaired or delayed
55 - 69 Mildly impaired or delayed
40 - 54 Moderately impaired or delayed

The Most Reliable IQ Tests

Intelligence is a versatile and dynamic concept so it’s not necessarily accurate to distil it into a single number. It should be noted that the score obtained by the IQ test actually shows logical and verbal intelligence.

However, the definition of intelligence is much more than just verbal and logical skills. Howard Gardner's theory of multiple intelligences supports this idea. supports this idea. For example, it may be necessary to perform a specific visual intelligence test to measure visual intelligence. Therefore, many different tests have been developed.

Stanford-Binet, Wisc-r and Leiter intelligence tests are the most widely-used tests worldwide. All of these tests are carried out in the presence of an expert. If you want to test your child's mental skills, you can use MentalUP, a pedagogical product approved by the Mental Health Association.

  • Concentration skills
  • Memory skills

How to Calculate the IQ Test Score

The most important feature of intelligence tests is to determine a reference point and interpret the results obtained from the test according to this reference point. In this sense, we can talk about reference points such as “real age” and “age of intelligence”.

Example: Imagine 500 8-year-old children who participate in an intelligence test. Assume that the average test score is 80/100. In this case, it can be assumed that children with an individual score of over 80 are smarter than their peers. Individuals with a score of 80 are considered to have normal intelligence, while those below 80 are considered to be behind their peers.

The online intelligence tests above use a similar logic The comparative performance report from the MentalUP intelligence test shows the results of the children of the same age as a reference point.
