How to Become a Police Sub-Inspector (SI) in India

A Sub-Inspector (SI) is an officer-rank position in the police, leading a police station team and investigating cases. There are two main routes: the SSC CPO exam and state police recruitment.

Two routes to becoming an SI

  1. SSC CPO — recruits Sub-Inspectors for Delhi Police and the Central Armed Police Forces (CAPFs) like BSF, CISF, CRPF. Conducted by the SSC.
  2. State Police Recruitment — each state recruits SIs through its own police recruitment board.
