The Inter-Services Intelligence (ISI) is Pakistan's premier intelligence agency, gathering and analyzing information critical to national security. Officer-level entry is open to both men and women through two distinct routes. This guide covers eligibility, the exam pattern, and the full selection process.
Two Routes to Become an ISI Officer
ISI does not run a standalone public recruitment portal for officers. Entry happens through:
- Armed Forces secondment — commissioned officers selected internally.
- Direct civilian entry — Assistant Director (Grade 17), advertised via Ministry of Defence.
Route 1 — Via Armed Forces (Army, Navy, PAF)
Commissioned officers selected internally — no direct application
- Join as a commissioned officer through PMA, PN, or PAF academies.
- Clear ISSB during initial selection.
- Serve for a number of years in your parent service.
- Selection for ISI secondment is on merit and ISI's discretion — there is no direct application for this route; eligibility and service terms follow your parent branch's commission, not a separate ISI contract.
For ISSB preparation, see our ISSB Forum guide. For a full eligibility breakdown before applying, check our Armed Forces Eligibility Checker.
Route 2 — Direct Entry as Assistant Director (Grade 17)
Advertised via FPSC, on merit, through Ministry of Defence notices
Assistant Director (Grade 17) — Eligibility & Facts
Eligibility
- ➤ Gender: Male / Female

- ➤ Education: Bachelor's degree (BA/BSc/BE), minimum 2nd division, HEC-recognized university — Master's or higher preferred
- ➤ Entry grade: BPS-17
- ➤ Advertised as: "AD, Ministry of Defence" — the hiring agency is not named in the ad
Job Nature

Where to Monitor Vacancies
- ➤ FPSC's official site (fpsc.gov.pk)

Since the post is listed generically as "AD, Ministry of Defence," applicants often don't know upfront which agency they're applying to.

Building Relevant Skills Before You Apply
