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 www.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.
