IQ is a measurement of intelligence expressed as a number. It is calculated by taking an intelligence test and comparing the score to average scores among peers. Common tests used in India include the Stanford-Binet test, which measures general mental ability. IQ tests are used for educational and vocational guidance, classroom teaching, clinical assessment, and research. However, IQ is not a complete measure of a person's abilities and should be interpreted cautiously, as verbal IQ tests may not capture all types of intelligence and one test score does not define a person.

 IQ is an acronym for Intelligence Quotient.
So what is IQ? The IQ is a measurement of
your intelligence and is expressed in a
number.
 A person's IQ can be calculated by having
the person take an intelligence test. The
average IQ is 100. If you achieve a score
higher than 100, you are smarter than the
average person, and a lower score means
you are (somewhat) less smart.

3. DEFINITION OF IQ :
 Measure of a person’s cognitive capacity
relative to his or her peers. It is computed by
dividing the person’s mental age(as
measured on a scale such as Stanford Binet
scale) by his or her chorological age, and
multiplying with 100.

4. HOW TO CALCULATE IQ…?
 The development of NORMS allow us to
compare one person’s test results to
another's.

21. CAUTIONS WHILE USING AN INTELLIGENCE TEST
 1. The teacher must recognize that I.Q. (especially from
verbal tests) is not a complete measure of a person’s worth.
It is an indication of only one limited type of ability.
 A person may have a good level of ability in many other non-
verbal aspects of living, i.e., mechanical, social, artistic and
musical. A child whose score on scholastic aptitude test is
low should in no way be rejected.
 2. Verbal group tests of intelligence must be supplemented
by other types of intelligence tests.
 3. Results of intelligence tests should not be declared to the
students in a way so as to label a particular student once for
all with a particular I.Q.
 4. In case it is suspected that the child was emotionally
disturbed at the time of testing, results should be considered
quite tentative.
 5. An I.Q. of 70 should be interpreted as an I.Q. somewhere
between 60 and 80.
