IQ Rating Scale Deciphered!

The IQ rating scale is built with a mathematical comparison of your mental age with your chronological age, and the result is multiplied by 100 for normalization. Lewis M. Terman, professor of psychology, is quoted to give IQ rating scale a mathematical name of “Intelligent Quotient”. And your mental age is determined by IQ tests which are standardized after testing thousands of children and adults.

The psychologists have concluded that the genius and the feeble minded people have the same type of mind. However, the teachers and parents under-estimate the intelligence of ‘feeble minded’ children and overestimate the intelligence of ‘superior’ children. Mr. Lewis M. Terman was the first psychologist to claim with data that women don’t have lower IQ than the male members of a society.

Units of IQ Rating

The IQ rating scale is built by measuring your mental age as a percentage of your actual age. The IQ ratings of adult range from 20 to 200 scores. The skeptics have been raising a number of objections not only on the IQ test methodologies but also on the IQ rating scales. Modern psychologists have dropped the notion of mental age to avoid heavy criticism of the skeptics.

Now the IQ rating is evaluated on the ground of statistical division of scores as of Stanford-Binet test for children and the Wechsler test for adults. An IQ score above 130 is thought to be gifted while a score below 70 reflects mental impairment or mental retardation.

Original IQ Rating Scale

As described previously, Mr. Lewis Terman was the originator of the term of the IQ in 1916. He presented the IQ rating scale in different categories as under:

IQ Ratings of Over 140 - Genius or near genius

IQ Ratings of 120 to 140 Highly intelligent

IQ Ratings of 110 to 119 Very intelligent

IQ Rating of 90 to 109 Normal or average intelligence

IQ Ratings of 80 to 89 Dullness

IQ Rating of 70-79 Borderline deficiency

IQ Ratings Under70 Definite feeble-mindedness

Terman observed that lower average IQ is found in criminals, members of lower social classes, Indians, Mexicans, and blacks, and provided scientific evidence for racial prejudices. Later these cultural biases of IQ tests were challenged and refuted.

Distribution OF IQ Score

Mr. Terman has distributed IQ scores on the following scales:

• 50% of IQ scores fall between 90 and 110

• 70% of IQ scores fall between 85 and 115

• 95% of IQ scores fall between 70 and 130

• 99.5% of IQ scores fall between 60 and 140

• 5% of people have an IQ under 70. This is generally considered as the emblem for “mental retardation”, a situation of limited mental abilities and the scorers face hardships in all fields of life and specially adapting to the demands of life.

The score of 70 of mental retardation is further divided into 4 levels:

1. 50-70 - Mild mental retardation (85%)

2. 35-50 - Moderate mental retardation (10%)

3. 20-35 - Severe mental retardation it is (4%)

4. I0 - 20 - Profound mental retardation (1%)

High IQ Rating Scale

When you score considerably high score there are chances that you may fall in the category of genius people. An IQ scoring of 140 to 145 definitely qualifies you for this category. The psychologists believe that 1 out of 400 people can score this level. However, the high IQ score has its own sub-divisions:

• IQ Ratings OF 115-124 Above average

• IQ Rating OF 125-134 Gifted

• IQ Ratings OF 135-144 Highly gifted

• IQ Score OF 145-154 Genius

• IQ Score OF 155-164 Genius

• IQ Scoring OF 165-179 High genius

• IQ Scoring OF 180-200 Highest genius

• IQ Scoring OF 200 or above Immeasurable genius”

The modern IQ tests produce scores for different fields as language fluency, three-dimensional thinking and the summary score calculated from subtest scores. On the other hand the intelligence quotient is an ambiguous measure of the ability and power of the brain.

It is said that Einstein had the IQ of 160 and that is not the most gifted or Immeasurable genius. The higher IQ rating is a natural and innate ability that can also be improved. But it is not sure measure of your success. But a high IQ rating can’t guarantee a success in your life. A success can only be achieved with clarity of goals, fixation of purpose and persistency in your action.
