Mechanical Reasoning Assessment
What it is, what it measures, and when to use it.
Overview
The Mechanical Reasoning assessment measures a candidate's ability to observe, interpret, and reason about how everyday physical situations behave; identifying patterns, predicting outcomes, and working through problems that require no specialist knowledge or prior technical experience.
It is not a knowledge test. Candidates are not expected to recall formulas, technical terminology, or engineering principles. Every question can be solved from the diagram alone, using the kind of physical intuition that develops through everyday experience. What is being measured is the ability to reason carefully from what is shown; to look at a physical situation and work out what will happen next.
How It Works
Candidates work through a series of questions across four areas of mechanical reasoning. Each question presents a visual diagram and four answer options; one is correct, the other three represent plausible but incorrect reasoning paths.
Questions vary in difficulty. Some ask for a single inference from the diagram. Others require two or three reasoning steps in sequence, where each step builds on the last. The most challenging questions involve counterintuitive outcomes; situations where the physically correct answer is not what most people would initially expect.
No specialist background is required to attempt the assessment. The diagrams are designed to be self-explanatory, and the questions are phrased in plain language.
What It Covers
The assessment is organised into four facets. Each facet targets a distinct area of Mechanical Reasoning.
|
Area |
What it assesses |
|---|---|
|
Forces, Levers & Simple Machines |
Assesses the ability to reason about how force is applied and amplified through levers and simple mechanical tools: predicting movement direction, comparing effort across different configurations, and understanding how fulcrum position affects mechanical advantage |
|
Gears, Pulleys, Belts & Transmission |
Assesses the ability to trace how motion and speed transfer through linked mechanical components such as gear chains, pulley systems, and belt drives: determining rotation direction and understanding how configuration affects output |
|
Gravity, Weight & Equilibrium |
Assesses the ability to reason about how weight and distance interact to produce balance or imbalance: predicting whether a system will tip, locating the centre of gravity, and determining how loads distribute across supports |
|
Fluid Mechanics & Pressure |
Assesses the ability to reason about how liquids behave in connected systems under gravity and pressure: predicting flow direction, understanding pressure transmission, and distinguishing between fluid weight and buoyancy |
When to Use It
The Mechanical Reasoning assessment is well-suited to any hiring process where the ability to understand and reason about physical systems is relevant to job performance. It is most commonly used for:
- Engineering and technical roles - mechanical, civil, electrical, and industrial engineers; engineering technicians and graduates
- Operations and maintenance - plant operators, maintenance technicians, field service engineers, facilities managers
- Skilled trades - mechanical fitters, pipefitters, HVAC technicians, automotive and industrial mechanics
- Manufacturing - production operators, quality control technicians, assembly line supervisors
- Construction and infrastructure - site supervisors, structural assessors, project engineers
- Marine and defence - naval technicians, submarine operators, shipyard engineers
The assessment is designed to be fair across candidates with different educational and professional backgrounds. It does not require formal engineering training, which makes it suitable for entry-level as well as experienced technical roles.
Understanding the Results
Each candidate receives an overall Mechanical Reasoning score reflecting performance across all four facets. Facet-level scores are also available, allowing employers to see where a candidate's mechanical reasoning is strongest and where gaps may exist.
FAQs
Does a candidate need an engineering background to take this assessment?
No. The assessment is designed so that every question can be answered from the diagram alone, using everyday physical intuition. Candidates with no engineering training regularly perform well. Prior exposure to mechanical environments may help, but it is not required and is not being tested.
Can candidates prepare for it?
There is no specific preparation that provides a meaningful advantage. Familiarity with how physical objects behave, developed through practical experience, hobbies, or general curiosity about how things work, is the kind of background that tends to support performance.
Is it suitable for senior as well as junior roles?
Yes. The assessment includes questions across three difficulty levels, which makes it sensitive enough to differentiate performance across a wide range of candidates, from entry-level technicians to senior engineers and operations managers.
How is Mechanical Reasoning different from Spatial Reasoning?
Spatial Reasoning measures the ability to mentally rotate, fold, and navigate objects and environments in two and three dimensions. Mechanical Reasoning measures the ability to reason about physical systems, forces, motion, balance, and fluid behaviour. There is some overlap in that both involve visual stimuli and non-verbal reasoning, but they tap into genuinely distinct abilities. A candidate can be strong in one and average in the other.
Can it be used for development as well as selection?
Yes. In addition to hiring, the assessment can support talent development, internal mobility decisions, and learning programme design — particularly where mechanical reasoning is relevant to performance, safety, or technical progression.
Is the assessment fair to candidates from non-technical backgrounds?
The assessment was developed with fairness as a central design requirement. No item requires specialist vocabulary, formula recall, or prior training. Every question is solvable from the diagram alone. Scenarios are drawn from neutral, everyday contexts - everyday objects, natural environments, and generic technical schematics - and have been reviewed to avoid cultural bias or gender-coded framing.
