Candidates need to qualify NDA examination in order to go to the next round i.e. the SSB interview. The candidates who get selected in the BBS round are eligible to take admission in NDA.

Intelligence and Personality Test

The SSB procedure consists of the 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 a 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 details of these tests are given on the website join Indian 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 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.
