Out of maximum marks assigned to part ‘B’ of this paper, questions on Sections ‘A’, ‘B’, ‘C’, ‘D’, ‘E’ and ‘F’ will carry approximately 25%, 15%, 10%, 20%, 20% and 10% weightages respectively.
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.
