The Inter Services Selection Board (ISSB) is the core selection system for candidates who wish to become commissioned officers in the Pakistan Army, Navy, or Air Force.

For candidates planning to appear in ISSB 2025, this guide covers everything you need to know, including eligibility requirements, test structure, preparation strategies, and practical tips to improve your chances of success.

1. What Is ISSB?

ISSB is a multi-day evaluation process designed to assess a candidate’s overall personality rather than academic knowledge alone. The board examines natural behavior and officer-like qualities through different activities, tests, and interviews.

ISSB evaluates qualities such as:

• Intelligence and reasoning ability

• Leadership potential

• Confidence and communication skills

• Discipline and teamwork

• Emotional stability

• Decision-making under pressure

Unlike traditional exams, ISSB focuses on how you think, behave, and interact in real-life situations.
