Security Assistant B (DRDO)

The governing DRDO security-post recruitment rules identify Security Assistant ‘B’ as a promotion post, not a direct-recruitment post: an eligible Security Assistant ‘A’ requires eight years of regular service in the A grade. Selection is considered through a decentralised Departmental Promotion Committee structure involving DRDO laboratory or establishment leadership and senior administrative/scientific officers.

For a person beginning outside the cadre, the cited rules show the feeder entry point as Security Assistant ‘A’: direct recruits required 12th-class pass or equivalent, physical fitness and capability for strenuous duties, and successful completion of the prescribed training course before confirmation. Applicants should treat these as the rules-based pathway rather than assume an open B-level vacancy; DRDO’s CEPTAM is the recruitment channel for DRTC, Administration and Allied Group B/Group C posts, and live advertisements control the actual eligibility, vacancies, dates, tests and relaxations.

• Start in the Security Assistant ‘A’ feeder grade through the applicable DRDO/CEPTAM notification.
• Complete the required A-grade regular service period: eight years under the cited 2012 rules.
• Meet the conditions of the applicable promotion process and be considered by the departmental promotion committee.
• Verify the current recruitment notification and any later rule amendment before applying; historical recruitment rules do not themselves announce vacancies.

The recruitment rules place the post in DRDO’s Ministry of Defence security cadre and repeatedly refer to DRDO laboratories and establishments. For promotion matters, the rules provide decentralised Departmental Promotion Committee groups involving participating laboratories or establishments, indicating that the cadre is administered across DRDO’s research-establishment network rather than as a single standalone office cadre.

• Central Government civilian post in DRDO’s security cadre.
• Group ‘C’, non-gazetted and non-ministerial classification in the cited rules.
• Career decisions under the cited rules involve laboratory/establishment-based decentralised promotion committees.
