Intelligence and Personality Test
The SSB procedure consists of two stage Selection process - stage I and stage II. Only those candidates who clear the stage I
are permitted to appear for stage II. The details are :
(a) Stage I comprises of Officer Intelligence Rating (OIR) tests are
Picture Perception * Description Test (PP&DT). The candidates
will be shortlisted based on combination of performance in OIR
Test and PP&DT.
(b) Stage II Comprises of Interview, Group Testing Officer Tasks,
Psychology Tests and the Conference. These tests are conducted
over 4 days. The details of these tests are given on the website
joinindianarmy.nic.in.
The personality of a candidate is assessed by three
different assessors viz. The Interviewing Officer (IO), Group
Testing Officer (GTO) and the Psychologist. There are no separate
weightage for each test. The mks are allotted by assessors only
after taking into consideration the performance of the candidate
holistically in all the test. In addition, marks for Conference are
also allotted based on the initial performance of the Candidate in
the three techniques and decision of the Board. All these have
equal weightage.
The various tests of IO, GTO and Psych are designed to
bring out the presence/absence of Officer Like Qualities and their
trainability in a candidate. Accordingly candidates are
Recommended or Not Recommended at the SSB.
