  • What is CDS SSB:
  • 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:-
  • 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. Interviewing Officer (IO), Group Testing Officer (GTO) and Psychologist. There are no separate weightage for each test. The marks are allotted by assessors only after taking into consideration the performance of the candidate holistically in all tests. 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 weight age.
