  5. Day 5 (Conference): All assessors convene. Candidates appear briefly before the full board, followed by the declaration of recommended candidates.

The 15 Officer Like Qualities (OLQs)

The SSB psychological system does not search for encyclopedic knowledge; it measures your innate potential across 15 well-defined Officer Like Qualities divided into four psychological factors:

  • Factor I (Planning and Organizing): Effective Intelligence, Reasoning Ability, Organizing Ability, Power of Expression.
  • Factor II (Social Adjustment): Social Adaptability, Cooperation, Sense of Responsibility.
  • Factor III (Social Effectiveness): Initiative, Self Confidence, Speed of Decision, Ability to Influence the Group, Liveliness.

Armed Forces Medical Standards and Physical Conditioning

Recommended candidates proceed to the Special Medical Board (SMB). Common reasons for temporary medical rejection include being overweight, carrying angles beyond permissible limits, ear wax, DNS (deviated nasal septum), and dental points below 14. Begin building physical conditioning months before the SSB: establish a routine of running 2.4 kilometers within 15 minutes, 20 push-ups, and 6–8 pull-ups daily.
