OIR Test in SSB - Officer Intelligence Rating
~8 min read
- Format: Two booklets — Verbal Reasoning and Non-Verbal Reasoning — administered back-to-back on Day 1.
- OIR grades run 1–5. OIR 1 is highest. OIR 2–3 is the safe zone for most entries. OIR 4–5 is a concern.
- Not a standalone filter: A weak OIR combined with a weak PPDT tips the screening decision. OIR alone rarely eliminates a candidate.
- What it actually measures: Speed and accuracy of pattern recognition and logical reasoning — not academic knowledge.
Upcoming change: The Indian Army has confirmed that the existing OIR test will be replaced by the CSS (Computerized Stage 1 Selection System) with an integrated OPAM (Objective Personality Assessment Measure). The rollout date will be announced on joinindianarmy.nic.in; the existing OIR system described on this page continues until that announcement. See our Computer-Based Stage 1 guide for what is changing and what stays the same.
The OIR is the most mechanical thing that happens in five days at the SSB. There is no assessor making notes, no group dynamic, no judgement about your character — only a printed booklet, a stopwatch, and an answer sheet. It is also the test most candidates over-prepare for in the wrong way: they read it as the cognitive gatekeeper of the selection board when, in practice, it is a single input into one decision (whether you stay for Days 2–5). The grade itself does not follow you any further. The IO will never see it. The Psychologist will never see it. The GTO will never see it. The OIR exists to filter, and once it has filtered, it is filed.
What is the OIR Test?
OIR stands for Officer Intelligence Rating. It is a standardised group-administered test of verbal and non-verbal reasoning ability. The test consists of two separate booklets administered in sequence:
- Booklet 1 — Verbal Reasoning: Tests reasoning ability through language-based problems. Common question types include analogies, classifications, odd-one-out, number series, and coding-decoding.
- Booklet 2 — Non-Verbal Reasoning: Tests reasoning ability through visual patterns and figures. Common question types include figure matrices, pattern completion, spatial reasoning, and hidden figures.
Each booklet is timed separately. Both are multiple-choice format. Speed is critical — the number of attempted and correctly answered questions within the time limit determines the raw score.
OIR Grade Table
| OIR Grade | Meaning | Typical Outcome |
|---|---|---|
| OIR 1 | Highest — well above average for the batch | Strong screen-in indicator. Intelligence concern is effectively eliminated from the screening equation. |
| OIR 2 | Above average | Good screen-in indicator. PPDT performance remains important but OIR is not a concern. |
| OIR 3 | Average for the batch | Neutral — does not help or hurt. PPDT performance becomes more decisive at this grade. |
| OIR 4 | Below average | Concern flag. A strong PPDT performance can still result in screen-in but the bar is higher. |
| OIR 5 | Significantly below average | High probability of screening out unless PPDT performance is unusually strong. The combination of OIR 5 + average PPDT almost always means screen-out. |

| Duration per booklet | Approximately 17–20 minutes each |
| Total duration | 35–45 minutes for both booklets |
| Questions per booklet | Approximately 40–50 questions |
| Marking | Correct answer = 1 mark. No negative marking in most OIR formats (confirm for your specific board). |
| Setting | Group-administered in the main hall; answer on the OMR-type answer sheet provided |
Section Breakdown
| Booklet | Section type | What it tests | Example |
|---|---|---|---|
| Verbal | Analogies | Ability to identify relationships between word pairs | Doctor : Hospital :: Teacher : ? (School) |
| Verbal | Classification / Odd one out | Identifying the item that does not share a common property with the rest | Apple, Mango, Carrot, Banana — Carrot is the odd one (not a fruit) |
| Verbal | Number / Letter series | Identifying the next term in a logical sequence | 2, 6, 12, 20, 30, ? (42) |
| Verbal | Coding-Decoding | Applying a consistent rule to encode or decode words/numbers | If CAT = 3-1-20, then DOG = ? |
| Non-Verbal | Pattern completion | Identifying which option correctly completes a visual pattern with a missing piece | 3x3 grid with one cell missing; choose the correct cell from 4 options |
| Non-Verbal | Figure matrix | Identifying the rule governing the transformation across a row/column of figures | Shapes change in a consistent rule across 3 cells; which option continues the rule? |
| Non-Verbal | Hidden figures | Identifying a simpler shape that is embedded within a more complex figure | A given triangle must be found within a more complex drawn figure |
| Non-Verbal | Mirror images / spatial rotation | Visualising how a figure appears when reflected or rotated | Given a shape, which option is its mirror image? |
How OIR is Scored — Raw Score to Grade
The OIR grade is not calculated from a fixed pass mark. It is norm-referenced — your raw score is compared against the batch you are sitting with. The distribution of scores in the batch determines the grade cut-offs for that sitting.
This has an important implication: the same raw score can produce different OIR grades in different batches. A score of 68/100 in a batch of 40 candidates who average 50 may give OIR 2. The same score in a batch averaging 72 may give OIR 3. There is no single "target score" — the goal is to perform as well as possible relative to the batch.
What the OIR Grade Actually Controls
This is the most commonly miscommunicated fact on the SSB internet. Candidates are told the OIR grade matters for recommendation, for merit list, for the Psychologist's view of intelligence. It does not. The OIR grade is used for exactly one decision: in combination with the PPDT, whether you are screened in to Days 2–5. Once that decision is taken, the OIR booklet is filed and the grade does not travel.
- The IO does not see it. When you walk into the interview on Day 3 or Day 4, the Interviewing Officer's file contains your PIQ and Self Description — not your OIR grade. Their assessment of your Reasoning Ability and Effective Intelligence is built from how you answer questions and how you connect the dots in your own life, not from how you handled a number series.
- The Psychologist does not see it. Your TAT, WAT, SRT, and SD are evaluated against psychological criteria, not against your performance on a reasoning booklet a day earlier.
- The GTO does not see it. Group tasks are assessed on observable behaviour. The GTO has no need for and no access to your OIR band.
- The conference does not see it. At Day 5 the three assessors compare their OLQ profiles. The OIR is not part of that conversation.
What this means in practice: a candidate with OIR 4 who has been screened in (because their PPDT was strong enough to compensate) starts Day 2 with a clean slate. The OIR is not a continuing handicap. It is also not a continuing tailwind — an OIR 1 candidate who is screened in does not begin the rest of the assessment with credit in the bank. The four remaining days are assessed entirely on the four remaining days.
Pattern Recognition vs Speed — Which Matters More
Candidates spend disproportionate effort hunting for "trick" patterns and obscure question types. In a real OIR booklet, the question types are familiar: analogy, classification, series, coding-decoding, figure matrix, mirror image, paper folding, hidden figures. None of them are novel. What is novel is the time pressure — roughly 30 to 40 seconds per question, with no opportunity to circle back at leisure.
The honest answer to the question candidates keep asking is this: speed is the binding constraint, and once you have practised the patterns, novel patterns are rare. A candidate who has worked through 800–1,000 mixed reasoning questions over six to eight weeks has seen every type the booklet contains. What separates an OIR 1 from an OIR 3 in such a candidate is not pattern coverage; it is the half-second-per-question of decision time saved by familiarity with the structure. That half-second compounded across 90–100 questions is the entire difference between bands.
The implication for preparation is direct. Stop searching for new question types once you have seen each of the seven or eight standard ones. Start practising the ones you have seen, against the clock, until your decision time per question is shorter than you can articulate. The goal is not "I solved 45 out of 50" — it is "I never sat on a question for more than 35 seconds, including the ones I marked best-guess."
Does a Poor OIR Grade Eliminate You?
No — but it increases the burden on your PPDT performance. The SSB uses both OIR and PPDT to make the screening decision. The weighting is not publicly specified, but the pattern observed over many SSB sessions is:
- OIR 1–2 + Average PPDT: Usually screened in. Strong intelligence signal compensates for average narrative leadership.
- OIR 3 + Strong PPDT: Usually screened in. Compensatory balance.
- OIR 4 + Strong PPDT: Possible screen-in, but borderline. The PPDT has to be clearly strong.
- OIR 4–5 + Average or Weak PPDT: Almost always screened out. Neither measure shows the threshold level for officer commissioning.

Sample OIR Questions — Verbal and Non-Verbal
These questions illustrate the format and difficulty level of OIR questions. Actual questions are not publicly released — practice with similar material from standard reasoning books (R.S. Aggarwal's Verbal and Non-Verbal Reasoning is widely used). OIR Grade 1 is the highest; a grade of 3 or better is generally considered comfortable for screening purposes — but the board uses OIR in combination with PPDT, not in isolation.

| # | Type | Question |
|---|---|---|
| V1 | Odd-one-out | Which is the odd one? (a) Copper (b) Iron (c) Zinc (d) Brass Brass is an alloy; the others are pure metals. |
| V2 | Odd-one-out | Which is the odd one? (a) Flute (b) Sitar (c) Tabla (d) Violin Tabla is a percussion instrument; the others are string or wind instruments. |
| V3 | Analogy | Pen : Author :: Scalpel : ? (a) Hospital (b) Nurse (c) Surgeon (d) Patient (c) Surgeon — a pen is the tool of an author; a scalpel is the tool of a surgeon. |

Non-Verbal Reasoning — Question Types and Text-Based Examples
Non-verbal OIR questions use printed figures — shapes, grids, and patterns. Since figures cannot be reproduced here as images, the following describes each question type with a text-based equivalent to develop the underlying skill. Practise the actual figure-based versions from a standard reasoning book.
| Type | Description | Text-Based Practice Example |
|---|---|---|
| Matrix Completion | A 3×3 grid with 8 shapes following a rule. Find the 9th cell. The rule can apply across rows, down columns, or diagonally. | Grid: Row 1 — A, B, C. Row 2 — D, E, F. Row 3 — G, H, ? If each row has letters in ascending order, the answer is I. What if each row adds 3 (A=1, D=4, G=7)? Then the 9th cell is the 10th letter: J. Identify the rule before answering. |
| Figure Series | A sequence of figures that changes by a consistent rule each step. Identify what comes next. | Letter series equivalent: A, C, F, J, O, ? — gaps of +2, +3, +4, +5, +6 — next gap is +7 → answer: V. In figure series, the rule applies to a shape's rotation, size, or number of sides. |
| Figure Analogy | First figure is to second figure as third figure is to ? — the same transformation applied to the third figure produces the answer. | Number analogy equivalent: 4 is to 16 as 5 is to 25 (squaring). In figure form: a shape with 3 sides is to a shape with 6 sides (doubled), as a shape with 4 sides is to a shape with 8 sides. |
| Figure Classification (Odd-one-out) | Five figures are shown. Four share a common property. Identify the one that does not. | Equivalent: {4, 9, 16, 25, 36, 50} — all except 50 are perfect squares. In figure form, four shapes might all have an even number of sides and one has an odd number. |
| Mirror Image | A figure is shown. Choose which option is its correct mirror image (reflection about a vertical axis). | Text equivalent: The mirror of the letter "b" is "d". The mirror of "p" is "q". For a right-pointing arrow →, the mirror image is ←. Practice by writing asymmetric letters and identifying their mirrors. |
| Paper Folding | A square paper is folded once or twice and a hole is punched. Identify how the holes appear when unfolded. | Fold the paper in half vertically. Punch one hole on the right half. When unfolded, two holes appear symmetrically — one on each half. The position of the second hole mirrors the first about the fold line. |
| Hidden Figures | A simple shape is hidden within a more complex figure. Identify which of five options contains the given shape. | Practice with this exercise: draw a simple right-angled triangle. Then look for it embedded within a star, a square, a hexagon, or a cross. Train your eye to isolate a specific shape from visual noise. |
| Dot Situation | A dot is placed in a specific position relative to two overlapping shapes. Find which option places the dot in the same relative position using different shapes. | If a dot is inside a triangle but outside a circle, the answer must show a dot inside one shape but outside the other — regardless of the shapes' sizes or orientations in the options. |
Preparation Strategy
- 8 weeks before SSB: Begin with untimed practice to understand the question types. Identify which types you are weakest at (for most candidates: figure matrices and coding-decoding).
- 6 weeks before: Shift to timed practice. Set 20 minutes per 40-question set. Track accuracy and attempted count. At this stage, accuracy matters more than speed.
- 4 weeks before: Increase pace. Aim for 45 questions in 17 minutes. You should be attempting near-full sets at reasonable accuracy.
- 2 weeks before: Run full two-booklet simulations at a time. After the session, review wrong answers immediately. Understand the error — was it a concept gap or a rushed mistake?
- Final week: Maintain pace with one practice set daily. Do not start new question types. Consolidate what you know.
- On the day: Skip and come back — if a question is taking more than 45 seconds, mark a best-guess answer and move on. Return only if time permits. An unanswered question is a guaranteed zero; a best-guess has positive expected value when there is no negative marking.

Get SSB CoachingFrequently Asked Questions
Is the OIR result communicated to the candidate?
No. The OIR grade is not shared with candidates at any point — not at screening, not after recommendation, and not in the feedback session. Only the final screen-in or screen-out decision is communicated.
Can I prepare for the OIR in two weeks?
Two weeks of focused practice can meaningfully improve your score, especially on section types you have previously under-practised. However, the OIR tests reasoning speed — an underlying cognitive habit. Building speed takes sustained practice over 6–8 weeks. Two-week intensive preparation is better than nothing but is not as effective as sustained preparation.
Are there separate OIR standards for NDA vs CDS candidates?
The OIR test is the same type of test for all entry types. The grade cut-offs are batch-relative, not entry-specific. However, NDA batches typically include younger candidates (17–19 years) while CDS batches include older graduates. The relative comparison is always within the batch you are part of.
Is there negative marking in the OIR test?
Most OIR formats do not have negative marking — but this should be confirmed for your specific batch by the invigilator before the test begins. If there is no negative marking, attempt all questions even if you are uncertain — a blank answer always scores zero, a guess has a 25% probability of being correct.
What is the difference between OIR and the PPDT in terms of how they contribute to screening?
OIR measures cognitive speed and reasoning ability — it is a quantitative, objective measure. PPDT measures narrative leadership behaviour — it is a qualitative, judgement-based measure. The screening board uses both together. OIR is typically weighted more heavily in batches where PPDT performance is uniformly average; PPDT carries more weight when OIR scores cluster around OIR 3 for most candidates.
Should I read the question carefully or trust my first instinct?
For OIR, a single careful read is correct. The time pressure means you cannot re-read multiple times. Train yourself to read once, process the question type, and commit. Candidates who re-read excessively run out of time by question 30. First-instinct guessing without reading is equally bad — you miss the logic of the question type.
