What actually happens at ISSB over the four days?
The short answer
ISSB is a four-day residential assessment at one of the Inter Services Selection Board centres, and it is the same board for the Army, the Navy and the Air Force. Day one is a screening: verbal and non-verbal intelligence tests, and candidates who do not clear them go home that day. Those who stay are then assessed three ways over the next two days, by a psychologist (written projective tests), a Group Testing Officer (outdoor and indoor group tasks) and a deputy president or board member (interview). On the final day the three assessors meet in conference and the board recommends you or does not. Nobody passes ISSB on one strong test; you are recommended when all three assessors independently see the same officer-like qualities.
What is ISSB, and why is it not a test you can cram for?
The Inter Services Selection Board is the common selection stage for a commission in the Pakistan Army, Navy and Air Force. You reach it only after clearing your service's own initial test and preliminary medical, so everyone on the board has already shown they can pass a written paper. ISSB is not asking whether you can; it is asking whether you have the temperament, the judgement and the social behaviour the forces want in an officer.
That is why it is built the way it is. Three assessors observe you independently across three different kinds of situation, over several days, and their findings are compared at the end. A candidate who performs on the GTO ground but writes contradictory responses in the psychological tests, or interviews well but goes quiet in the group discussion, gives the board an inconsistent picture, and inconsistency is the most common reason a capable candidate is not recommended.
Where and how long
ISSB centres operate at Kohat, Gujranwala, Karachi (Malir) and Quetta. You are allotted a centre and a reporting date by your service; you do not choose. Reporting is usually the day before testing begins, and you stay at the centre for the full period. Boarding, meals and the timetable are provided.
Day one: documentation and the screening tests
After reporting and document checks, you sit the intelligence tests. These are the same family of tests as the initial test you already cleared, but they are the gate to the rest of the board.
- Verbal intelligence. Word relationships, analogies, series, odd-one-out, simple arithmetic reasoning, coding and decoding. Volume and pace, not depth. Practise on Analytical Reasoning.
- Non-verbal intelligence. Figure series, pattern completion, mirror images, embedded figures. The same pace problem, in pictures.
Results are announced the same day. Candidates who do not clear the screening are released and travel home; the rest continue. The screening is where preparation pays most directly, because it is the one part of the board that is a pure test and it is the part that ends most attempts.
Do not treat the screening as a formality
Candidates who cleared the initial test comfortably assume the board's screening is a repeat. It is administered under stricter time pressure and the cut is real. Two weeks of timed verbal and non-verbal practice before your reporting date is the cheapest insurance on the whole process.
The psychological tests: what the psychologist is reading
Screened-in candidates sit a battery of written tests set by the board's psychologist, usually starting the same afternoon or the next morning. None of them has a right answer. They are projective: you respond quickly to a prompt, and the pattern across all your responses is what is assessed.
| Test | What you do | What it shows |
|---|---|---|
| Word Association Test (WAT) | A word is shown for a few seconds; you write the first sentence it brings to mind. Dozens of words in a row. | Your spontaneous attitude: whether your instinctive frame is constructive, evasive, negative or clichéd. |
| Situation Reaction Test (SRT) | A booklet of short everyday situations; you write what you would do in each, under a tight overall time limit. | Practical judgement, responsibility and whether you act or defer. |
| Picture Story Writing | A picture (sometimes ambiguous or blank) is shown briefly; you write a story about it in a few minutes. | How you see people and problems, and whether your protagonist takes initiative or waits. |
| Self-description / pointer story | Write how your parents, teachers, friends and you yourself see you; or short responses to guided prompts. | Self-awareness and consistency with what the interview and GTO later observe. |
| Incomplete sentences | Complete a series of sentence openings quickly. | The same attitudinal reading as WAT, from a different angle. |
Each test is covered in detail, with worked examples of good and poor responses, in ISSB psychological tests explained.
The GTO tasks: two days outdoors and in the group room
The Group Testing Officer assesses you in a group of roughly eight to ten candidates, across a sequence of indoor discussions and outdoor tasks spread over the middle two days. You are watched for how you behave in a group, not for whether the group finishes.
- Group discussion. Two topics, current or social, discussed by the group without a chair.
- Group planning exercise. A model situation with several problems to solve within constraints; the group agrees a plan and one candidate presents it.
- Progressive group task. A series of outdoor obstacles crossed by the whole group using given materials, under rules.
- Half group task. The same kind of obstacle, with the group split so quieter candidates are seen.
- Individual obstacles. A set of physical obstacles you attempt alone against the clock.
- Command task. You are put in charge, given a task and two or three helpers you choose, and expected to lead.
- Final group task. One last obstacle for the whole group, usually on the last testing day.
The rules of each task, the qualities the GTO is marking, and the behaviours that fail candidates who are physically fit and articulate, are in ISSB GTO tasks explained.
The interview
Somewhere in the middle two days, each candidate is interviewed individually by the deputy president or a board member. It runs anywhere from twenty minutes to over an hour, and it is built around your own history: your family, school, results, interests, general awareness and why you want a commission. Your responses in the psychological tests are available to the interviewer, and contradictions between what you wrote and what you say are noticed.
How to prepare for it, and the questions candidates report most often, are in the ISSB interview.
The final day: conference and result
On the final day the psychologist, the GTO and the interviewing officer meet in conference under the board president and compare their independent assessments of each candidate. Some candidates are called in briefly during the conference, which is normal and is not a sign either way. The result is announced at the centre before you leave: recommended or not recommended. Recommendation is not selection; your service then applies its final medical and merit before issuing a call-up.
Not recommended is not final
Candidates may reappear at ISSB, subject to the limits and waiting period the board publishes at the time, and many officers were recommended on a second attempt. What changes between attempts is rarely intelligence; it is consistency, self-awareness and group behaviour, all of which can be worked on.
Where ISSB sits in your service's process
| Service | Before ISSB | After ISSB |
|---|---|---|
| Army (PMA Long Course) | Registration, initial intelligence and academic tests at a selection centre, preliminary medical. | Final medical, GHQ merit, call-up to PMA Kakul. |
| Air Force | Registration, initial tests at an Information and Selection Centre, initial medical, and for some branches a further assessment. | Central medical board, final selection, PAF Academy. |
| Navy | Registration, initial tests at a recruitment centre, preliminary medical and interview. | Final medical, merit, Pakistan Naval Academy. |
