Deductive Reasoning Test (2026): Complete Guide, Examples & Strategies

A deductive reasoning test is a psychometric assessment that measures your ability to take a set of given rules or premises and apply them logically to reach a valid, certain conclusion. It is essentially a structured logic test — rather than guessing or relying on general knowledge, you are expected to use systematic, top-down thinking to solve a defined problem.

The most common version in corporate recruitment is the SHL Verify G+ Test, which uses an interactive format with five distinct question types — each requiring a different kind of logical constraint-solving. It is widely used across finance, consulting, technology, and engineering roles.

What Deductive Reasoning Tests Measure

These two reasoning types are often confused. Understanding the distinction helps you approach each test type with the correct mental framework.

The SHL Verify G+ is the most common deductive reasoning test in corporate recruitment. It is an IQ-based exam that combines logical, deductive, and mathematical question types in an interactive drag-and-drop interface.

Two Variants

Adaptive Difficulty — What This Means for You

The SHL Verify G+ uses computer-adaptive testing (CAT). If you answer a question correctly, the next question becomes harder. If you answer incorrectly, it becomes easier. This means:

• All candidates will find the test extremely challenging — this is by design, not a sign that you're performing badly.
• Not completing all questions within the time limit is normal and expected. Leaving questions unanswered does not automatically indicate poor performance.
• The scoring algorithm considers both your accuracy and the difficulty level of the questions you attempted.
• Do not slow down deliberately — attempting more questions at your natural ability level is better than answering fewer carefully.

The SHL Verify G+ contains five distinct question types. Each type requires a different approach. Familiarising yourself with all five before test day is critical — encountering an unfamiliar format mid-test costs significant time and focus.

Type 1Grouping / Room Assignment

You are given a set of individuals and a set of rooms (or groups), along with a list of constraints. Your task is to assign each individual to a room that satisfies all the conditions simultaneously.

Room preferencesMeeting durationRoom availability/capacityConflict constraints

How to answer:

1. Read all constraints before attempting any assignments — later constraints often invalidate early assumptions.
2. Start with the most constrained individual (the one with the fewest possible valid rooms) and assign them first.
3. Drag the green individual pins into the room slots that satisfy all conditions.
4. Use the blue reset button to clear all pins if you need to start over.
5. Double-check every constraint is satisfied before confirming.

✅

Complexity increases

Later questions in this type introduce more individuals, more rooms, and more constraints — often including conditional rules ("Person A can only share a room with Person B if Person C is not present"). Build your speed on simpler versions before tackling harder ones.

Type 2Ranking

You are given performance data or comparative information about a set of individuals and must rank them in the correct order from best to worst (or vice versa) by applying the rules provided.

Comparative performance dataRelative statementsConditional ordering rules

How to answer:

1. Read all performance statements and identify direct comparisons (A > B, C < D).
2. Build a chain: if A > B and B > C, then A > B > C.
3. Drag ranking numbers to the placeholder circles next to each individual.
4. Watch for indirect comparisons that must be inferred through chains.
5. Use the reset button to restart if you find a contradiction.

Type 3Schedule Clash (Finding Free Meeting Times)

You are shown the existing schedules of multiple individuals and must identify time slots where all required attendees are simultaneously available for a meeting of a specified duration.

Individual schedulesMeeting duration requirementAvailable time blocksRequired attendees

How to answer:

1. Scan each person's schedule to identify their busy blocks and mark them mentally.
2. Overlay the schedules to find windows where all required attendees are free.
3. Check that the free window is long enough for the required meeting duration.
4. Click on empty white blocks to select the valid time slot — blocks change colour to indicate your selection.
5. Confirm the selection satisfies the duration requirement before moving on.

Type 4Schedule Task (Fitting Tasks into Slots)

You are given a set of tasks with specific durations, ordering dependencies (Task B cannot start until Task A is complete), and available time slots. You must fit all tasks into the schedule without violating any constraint.

Task ordering dependenciesTask durationAvailable time slotsResource constraints

How to answer:

1. Identify tasks with prerequisite dependencies — these must be scheduled first.
2. Find the earliest available slot that satisfies the prerequisite and duration requirements.
3. Drag task rows to the appropriate free slots — slots change colour to match the task when placed correctly.
4. Continue until all required tasks are assigned.
5. Verify ordering dependencies are respected — a task placed before its prerequisite is a violation.

Type 5Calendar (Finding Valid Days)

You are given a calendar view and a set of conditions — individual availabilities, holiday periods, day-of-week preferences, and lead time requirements. You must identify which specific calendar day (or days) satisfies all conditions simultaneously.

Individual availability windowsHoliday / blocked periodsDay-of-week constraintsLead time requirements

How to answer:

1. Mark (mentally or on scratch paper) every blocked or unavailable day from all constraints.
2. Eliminate days that violate any single constraint — you need ALL conditions to be met.
3. Click on the calendar day that satisfies all remaining conditions.
4. Later questions may require selecting multiple valid days — confirm each one satisfies all conditions independently.

✅

Watch for multi-day questions

More advanced calendar questions ask you to find multiple days that each meet all conditions. Confirm each day you select independently — don't assume adjacent valid days are automatically correct.

The SHL Verify G+ uses a sophisticated scoring model that goes beyond simple right/wrong counting. Three factors combine to produce your final percentile score:

These three factors are combined and then compared against a reference norm group at a given ability level, producing a population percentile. The comparison group is typically calibrated for your career level and role type.

The SHL Verify G+ and similar deductive reasoning assessments are used across a broad range of sectors, particularly where roles require structured problem-solving, data analysis, or decision-making under constraints.

Deductive reasoning is one of the most trainable cognitive skills — performance improves significantly with structured practice. Here is a focused preparation plan. For a broader 3-week schedule covering all SHL test types, see our full preparation guide.

Step 1: Learn All 5 Question Types Before Practising

The biggest mistake candidates make is starting practice tests before understanding the five question formats. At 75–90 seconds per question, encountering an unfamiliar type during the real test costs you 30–60 seconds of confusion time on that question alone. Review all five types above and understand the mechanics of each drag-and-drop interface before attempting any timed practice.

Step 2: Develop Systematic Constraint-Solving Habits

• Start with the most constrained element: In grouping and scheduling problems, identify the person or task with the fewest valid options and place them first. This reduces combinatorial complexity significantly.
• Use elimination, not trial-and-error: Systematically rule out impossible placements before testing valid ones. This is faster and less error-prone under time pressure.
• Build chains for ranking questions: Convert all pairwise comparisons into a single ordered chain. Draw it out on scratch paper if needed — the visual representation makes chain-building much faster.
• Mark constraints before touching the interface: For calendar and schedule questions, mentally (or physically on scratch paper) block out all unavailable windows before looking for free slots. This prevents you from missing a constraint that's listed at the bottom of the question.

Step 3: Practice Under Timed Conditions

Aim for ~75 seconds per question in early practice, then reduce to ~60 seconds as you improve. Use our free deductive reasoning practice tests to build speed and confidence across all five question types.

Step 4: Learn When to Guess and Move On

Given the adaptive format, spending 4 minutes on a single question while leaving 5 unanswered is always worse than spending 90 seconds on it, making a best guess, and moving on. Your work rate contributes to your score — do not sacrifice it for perfect accuracy on individual hard questions.
