Cognitive Aptitude Assessment
Cognitive ability — the capacity for logical reasoning, pattern recognition and abstract thinking — is one of the strongest predictors of job performance across industries. This professional test measures general intelligence (g-factor) using non-verbal questions that are fair across languages and cultural backgrounds.
20–50 questions across four difficulty tiers. Scores are normalised to a standardised scale (mean 100, SD 15). Results include your cognitive score, percentile ranking and a breakdown by reasoning type.
Why cognitive assessments matter
Decades of meta-analytic research show cognitive ability predicts performance better than interviews, work samples, or references alone. Use it alongside personality assessments for the most complete candidate picture.

Understanding the Cognitive Aptitude Test
This is the only assessment in the suite that has right and wrong answers. It measures reasoning ability rather than personality, knowledge or experience, across 60 questions — twelve in each of five domains, graded through three difficulty tiers so the test keeps discriminating at both ends rather than bunching everyone in the middle.
It takes 30 to 40 minutes and is the most demanding thing we ask a candidate to sit. It is also, for certain kinds of role, the single most informative.
The five domains
- Verbal Reasoning
- Language logic, analogies and comprehension — extracting a precise meaning from imprecise text. Predicts how reliably someone reads a specification, a contract or an ambiguous customer complaint and comes away with the right interpretation.
- Numerical Reasoning
- Sequences, proportions and quantitative logic. Not arithmetic speed: the question is whether someone notices that a number is implausible before acting on it.
- Abstract Pattern Reasoning
- Visual logic and rule inference with no domain knowledge attached. Because it depends least on prior education, this domain travels best across different backgrounds and school systems.
- Working Memory
- Holding and manipulating several pieces of information at once. Strongly related to how well someone copes with interruption-heavy work and multi-step instructions.
- Spatial Reasoning
- Mental rotation and visual manipulation. Matters in engineering, design, logistics and manufacturing, and matters very little in most desk roles — weight it accordingly.
What cognitive testing predicts, stated honestly
Cognitive ability has long been reported as one of the strongest single predictors of job performance, on the strength of large meta-analyses from the late 1990s. That headline deserves a caveat that most vendors omit: more recent re-analyses correcting how those studies handled range restriction have put the true correlation appreciably lower than the classic figures suggested.
The honest summary is that cognitive aptitude remains a genuinely useful predictor — particularly for roles that are learning-intensive, novel or complex — but it is not the near-deterministic signal it is sometimes sold as. For a role where the work is well-defined and the main variable is diligence, Conscientiousness on the Big Five will tell you more.
Adverse impact, and why it matters to you
Cognitive tests tend to produce larger group differences in scores than personality measures do. Depending on where you operate, that carries real legal exposure, and everywhere it carries the risk of screening out capable people for reasons unrelated to the job.
Two practical guards. First, do not use a cutoff score unless you can articulate why the job requires that level of reasoning — "higher is better" is not a defensible standard. Second, never let a cognitive score be the only gate; combined with a structured interview and a work sample it adds information, but used alone it narrows a candidate pool in ways you will not be able to justify later.
Reading the result
The report gives an overall score plus a breakdown by domain, and the breakdown is usually the more useful half. A candidate who is strong on verbal and weak on spatial is not "medium" — they are a specific person who will do well in some roles and struggle in others.
Treat differences of a few points as noise. Any single sitting is affected by sleep, environment and how seriously the candidate took it, and no responsible decision should turn on a narrow gap between two people.
Frequently asked questions
- Is this an IQ test?
- It measures overlapping abilities but serves a different purpose. Our free IQ test is built for personal curiosity; this assessment is structured for hiring, with domain-level breakdowns and role-relevant interpretation rather than a single headline number.
- Can candidates prepare for it?
- Practice produces modest gains on any reasoning test, mostly by removing unfamiliarity with the format. That is one more reason not to draw fine distinctions between candidates with similar scores.
- Is there a time limit?
- The test is designed for 30 to 40 minutes across 60 questions. We recommend a quiet, uninterrupted setting, since the working memory items in particular are sensitive to distraction.
- Should I set a minimum score for a role?
- Only if you can explain why the job requires that level of reasoning. Arbitrary cutoffs create legal exposure and screen out capable candidates. Use the score as one input among several, not as a gate.
- How does this compare to personality assessments?
- Cognitive aptitude predicts how quickly someone learns and handles complexity. Personality predicts how they will behave day to day. For most roles the two together are considerably more informative than either alone.
