Screening Defence Services &

the I.Q. Factor

Lesson 1
I.Q.

THE DEFENCE FORCES OFFER BRIGHT CAREER PROSPECTS TO THE RIGHT CANDIDATE. A
FAIR IMPARTIAL AND SCIENTIFIC METHOD OF SELECTION CONSIDERED TO BE AMONG THE
WORLD’S BEST, ENSURES AN EQUAL AND REASONABLE OPPORTUNITY TO EITHER SEX.
INSPITE OF THAT WHETHER IT IS A CANDIDATE’S FIRST OR LAST CHANCE, HE OR SHE IS
RECOMMENDED ON THE BASIS OF ONE’S TRUE POTENTIAL ASSESSED AFTER DIFFERENT
APTITUDE TESTS. ONE IS TESTED INDIVIDUALLY AND IN GROUPS.
The I.Q. tests were introduced in India after the second World War with the underlying idea of
selecting individuals with foresight. These tests have been updated and streamlined from time to time.
Through years of application this test has been perfected to the level that it is now suitable for the
selection of deserving candidates in government as well as in private sector jobs.
I.Q. Would mean the mental ability to solve the problems quickly & correctly
The Services Selection Board defines intelligence as the global capacity of the indivdiual to act
purposefully, think rationally and get along effectively with his environment. The test is now broadly
regarded as a test of reasoning.

IF A CANDIDATE IS INTELLIGENT HE MIGHT TRANSLATE INTELLIGENCE INTO APTITUDE.
APTITUDE ITSELF CAN BE TERMED AS A COMBINATION OF CHARACTERISTICS INDICATIVE
OF AN INDIVIDUAL’S CAPACITY TO ACQUIRE SOME SPECIFIC KNOWLEDGE, SKILL, OR ACT
OF ORGANIZED RESPONSES.
The rate of I.Q. development during adolescence is much less than in childhood. Maximum I.Q. for
a given individual is attained in ages 7,14,16 & 18 years of age, depending on the relative position of
the individual on the intelligence scale of the population. A poet has put it thus : “He who is not
handsome at 20 strong at 30, rich at 40 & wise at 50, can never be handsome, strong rich and the wise.”
I.Q. Means to establish quick relationship between time and result achieved.
Intelligence Quotient
The mental age must be considered in relation to actual age in years and months if the I.Q. is to be
determined. A convenient device to show the difference keeping mental and chronological age is a
deciding factor, as age is not always the determined criteria to decide the I.Q. as individual is not the
same as his chronological age is. In case the mental age of an individual coincide, he can be termed as
having hundred intelligence quotient or in other words his I.Q. is 100. Therefore it follows that if his
mental age is lesser, than his I.Q. is less than 100. The entire process revolved on the assessment of the
