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.
