IQ tests are standardised after being given to many thousands of people, and an average IQ (100) established. The IQ score above or below this norm is used, according to a bell curve, to establish the subject’s actual IQ rating. Most people have IQ test scores that fall into the middle of the IQ scale (IQ chart). This means that average intelligence is found in approximately 50% of the population and ranges between an IQ of 90 and 110, with a IQ score of 100 being the "magic" number of average IQ. Our site collects statistics of IQ test results for 201 countries of the world. In each country, the average IQ may differ from the standard (100). Therefore, when summing up the results of all countries, the overall IQ scale (IQ chart) is slightly distorted from the normal distribution (bell curve). For the same reason, the average IQ differs from 100. If you look at the IQ scale of mono-ethnic and economically developed countries (Japan), then you will see that the bell curve is almost perfect.

IQ range and IQ levels.
Many people ask themselves the question: "How high is my IQ ?". IQ scores from 111 to 119 indicate bright intelligence. IQ scores from 120 and 129 indicates superior intelligence. IQ scores of 130 or over is indicative of giftedness. However, some tests vary slightly, and intellectual giftedness might be shown in a score of 135 and above, or 140 and above. Those persons who score over 160 are endowed with superior giftedness, often described as being in the "genius" category. However, the critical factor of intelligence is its development and use. Without development, application, and productivity, high intelligence is a valueless characteristic, both to the individual and to society. An individual who scores between 80 and 89 is usually considered a slow learner. Scores under 80 indicate varying degrees of mental handicaps. These people need to develop intelligence.
What happens if a person does not obtain an above average IQ score? This does not mean that the person does not possess aptitudes for different careers. Perhaps other tests might detect them. Although the IQ test itself will give you a fairly accurate index of your intelligence, there are many other aspects of the human intellect - such as creativity, musical talent, and psychomotor skills - that are not measured by an IQ test. IQ scores are not valid indicators of abilities in creative, psychomotor, and leadership areas. For example, lack of success on one of the tests may well point to an area of weakness, while stronger scores on another test may point to areas of study or work which will be comparatively easy for you.
About IQ (intelligence quotient) and IQ tests.
IQ is the abbreviation for "intelligence quotient". Intelligence is the capacity to learn or understand. It is this which determines how efficiently each of us deals with situations as they arise, and how we profit intellectually from our experiences. Intelligence of course varies from person to person, and is what tests of intelligence (IQ tests) attempt to measure. A properly validated test would have to be given to some 20,000 people and the results correlated before it would reveal an accurate measurement of a person’s IQ. However, adults have to be judged on an IQ test whose average IQ score is 100, and their results are graded above and below this norm according to known scores.
A knowledge of one's IQ has many advantages. Within the process of human development, an understanding of one's own potential and one's own limitations can be of enormous personal value. We all have both upward potential and personal limitations; IQ is but one of many indicators of both of these. It is important to know and to understand that many other factors come into play and are important to success and happiness. Motivation, sensitivity, industriousness, and capacity for love are among those factors and are among the abilities not measured by standard intelligence tests.
The test score, or IQ, stands for Intelligence Quotient. It is a specific numerical measurement of a less-than-specific concept - intelligence. Although IQ is an indicator of innate ability and potential, it is not a pure measure. Even the best test of innate ability is contaminated by specific ability factors and by information and skills gained through experience and learning. Nonetheless, IQ is a reasonably good descriptive and predictive measure. Intelligence test are, in one sense, a method of measuring mental capacity, and differences in IQ scores are indicative of differences in brain structure as well as differences that arise from exposure and experience.
Intelligence and intelligent capabilities are necessary for creativity to result in "good" products. The creative mind must have information, ideas, and concepts from which to draw. Although highly creative people do not necessarily show high IQ scores, they would not be capable of creative endeavor as described here if their intelligence capabilities were extremely low. When reference is made to "highly intelligent, highly creative" persons, the reference is to individuals who are highly creative and who have actual, though unregistered, IQ of 140 to 150 or even above. Experience shows that a majority of unusually creative persons tend to IQ score between 120 and 139 on standard intelligence tests.
To improve your functional IQ, the intelligence level at which you actually perform (not your measured IQ), you will find that reading and developing greater awareness of worlds other than your own is a superb mind-expanding activity. Read magazines and books, nonfiction and fiction, on topics of interest to you - travel, other cultures, art, archeology, science, technology, etc. Read anything that provides new kinds of information and insights into life in general. Expanding your scope of interest and base of knowledge will not only increase your level of mental functioning but will make life more interesting and will make you more interesting as well. The more IQ tests your take the sharper you become.
High intelligence test scores are but one of many indicators that a person has potential or demonstrated abilities that are clearly outstanding. A high IQ is an indication of giftedness and talent in academic and intellectual areas, but in addition to academic giftedness, there are other areas of human endeavor and accomplishment in which a person may also be gifted. IQ scores are not valid indicators of abilities in creative, psychomotor, and leadership areas.
IQ scores will normally vary somewhat on different occasions and among different tests IQ. There should, however, be an exhibited range of IQ scores within about a 20-point variation. Reasons for this normal IQ range of variation result from the following facts:
1. There are some differences in the IQ tests themselves.
2. Differences in testing conditions will influence an individual's performance on IQ tests at different times.
3. The physical and mental well-being of the person taking the IQ test will vary from one time to another.
