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 :

  • 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.
  • Stage II Comprises of Interview, Group Testing Officer Tasks,Psychology Tests and the Conference. These tests are conducted

over 4 days.

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 weight age for each test. The marks 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 inthe three techniques and decision of the Board. All these have equal weight age.

The various tests of IO, GTO and Psych are designed to bring out the presence/absence of Officer Like Qualities and their train ability in a candidate.
