SSB Screening Test — Complete Guide to OIR & PPDT
Understand the first stage of SSB selection, including OIR test and PPDT process, and how candidates are screened on Day 1.
Built for serious defence aspirants preparing for SSB interviews
What is the SSB Screening Test?
Day 1 elimination stage of SSB that filters candidates through OIR and PPDT
The SSB Screening Test is the first stage of the 5-day Services Selection Board process. It is conducted on Day 1 and is designed to filter candidates down to a manageable group that will proceed to the remaining four days of assessment.
The screening consists of two components — the Officer Intelligence Rating (OIR) test and the Picture Perception and Discussion Test (PPDT). Both tests are conducted in the same session and results are declared on the same day.
Statistically, a large proportion of candidates — often between 50% and 70% — are screened out on Day 1. This makes the Screening Test a critical first hurdle that requires focused, specific preparation.
First stage of the 5-day SSB process
Conducted Entirely on Day 1
Includes both OIR and PPDT tests
Majority of candidates are screened out at this stage
Structure of the Screening Test
Two distinct components assessed on the same day
Officer Intelligence Rating Test (OIR)
Verbal and non-verbal reasoning test conducted under time pressure. Measures intelligence, processing speed, and logical ability against an officer-level benchmark..
Duration: Typically 30–40 minutes with multiple-choice
Picture Perception and Discussion Test (PPDT)
Candidates are shown a picture for 30 seconds and must write a story based on their perception. This is followed by a group discussion where candidates present and discuss their stories.
Components: Story writing + Group discussion
Screening Result Announcement
Results of the screening test are usually announced on the same day (Day 1) evening. Candidates who pass the screening test proceed to Stage 2 testing. Those who are screened out return home on Day 1 itself.
Officer Intelligence Rating (OIR) Test
Understanding what OIR tests and how it is scored
What is OIR?
The OIR test is a standardised intelligence assessment used to rate candidates on a scale. It consists of two separate booklets — Verbal Reasoning and Non-Verbal Reasoning — administered consecutively with strict time limits. The combined performance determines the candidate’s OIR grade, which factors into the screening decision alongside PPDT performance.
OIR performance plays a crucial role in screening, as it forms the initial assessment of a candidate’s intellectual ability before PPDT evaluation.
Types of Questions
Verbal Reasoning
Non Verbal Reasoning
Both verbal and non-verbal sections are time-bound and require quick decision-making under pressure.
What is Assessed
OIR questions are moderate in difficulty, but the strict time limit makes the test challenging. The real difficulty lies in balancing speed and accuracy. Candidates who manage time effectively and avoid overthinking perform well in this stage.
Practice OIR Questions
Picture Perception and Discussion (PPDT) Test
A decisive stage where your thinking, communication, and group behaviour are evaluated together
PPDT is often the deciding factor in screening, especially for candidates with similar OIR performance.
Why Candidates Get Screened Out in PPDT
STAGE 1 — IMAGE & STORY WRITING
A blurred image is projected for 30 seconds. Candidates observe it and then write a story in four minutes. The story should have a clear protagonist, a situation, actions taken, and a resolution. Assessors look for clarity of perception, logical flow of events, and the presence of a proactive main character demonstrating officer-like qualities.
STAGE 2 — INDIVIDUAL NARRATION
Each candidate narrates their story aloud to the group in 60 seconds. Assessors observe communication clarity, confidence, voice modulation, eye contact, and the ability to present ideas concisely. The narration is not a reading — it should be delivered from memory or with minimal reference to notes. Confidence and clarity matter more than language complexity.
STAGE 3 — GROUP DISCUSSION
After all narrations, the group discusses to arrive at a single common story within 10–15 minutes. This is not a debate — the objective is consensus. Assessors observe how each candidate contributes, whether they listen actively, how they handle disagreement, and whether they help the group reach a conclusion. The goal is not to dominate but to contribute meaningfully and help the group reach a common conclusion.
What is Assessed
Why Candidates Get Screened Out in PPDT
- Inconsistent or unrealistic stories
- Poor narration clarity
- Over-dominating or completely silent in discussion
- Lack of cooperation in group

How the Screening Decision is Made
The screening outcome is based on a combination of OIR score and PPDT performance. Neither test alone determines the result — both contribute to the assessor’s recommendation.
OIR Performance
The OIR rating is based on speed and accuracy across both reasoning booklets. Candidates must meet a minimum intelligence threshold set by the board.
PPDT Story and Narration
The quality, positivity, and structure of the written story along with the clarity and confidence of the individual narration are evaluated by the Assessor.
Group Discussion Behavior
How a candidate engages in the GD — whether they contribute constructively, listen actively, and help the group reach a consensus — influences the screening decision.
Common Mistakes in SSB Screening
Errors that cause candidates to be screened out unnecessarily
Memorising stories for PPDT
Pre-planned or rehearsed stories are easy to detect. Assessors look for natural, spontaneous, and positive thinking — not polished narratives.
Poor narration delivery
A good story with poor narration loses impact. Speak clearly, maintain a reasonable pace, and make eye contact with the group during narration.
Dominating or going silent in GD
Both extremes hurt. Dominating the discussion blocks others; staying silent signals low confidence. Contribute meaningfully and build on others’ points.
Lack of clarity in thought
Vague stories, unclear characters, or no resolution in PPDT stories signal poor perception. Train yourself to form structured, purposeful narratives quickly.
How to Prepare for SSB Screening
A structured approach across both OIR and PPDT components
Practice reasoning daily
Solve verbal and non-verbal reasoning sets under timed conditions. Focus on improving both speed and accuracy before the test.
Improve observation skills
Train yourself to quickly identify key elements in images — characters, setting, action. This sharpens story formation speed for PPDT.
Work on spoken communication
Practice speaking aloud about varied topics. Record yourself narrating short stories. Work on clarity, pace, and confidence.
Attempt mock PPDT sessions
Use practice images and write stories within 4 minutes. Narrate them aloud and simulate GD discussions with peers or using structured prompts.
