An Ultimate Guide to Cognitive Assessment Test


The fundamental aspect of recruiting boils down to understanding how a candidate will perform in the job. The hard part, however, is figuring that out. For example, how do you know if a candidate can employ mental processes to solve complex problems at work or possess the ability to pick up new skills at work? How would you know if the candidate can make effective decisions under pressure? Cognitive assessment tests provide answers to these questions.

When making a hiring decision, you pull out all stops to ensure that the prospective hire delivers results. However, many businesses have to spot “diamonds in the rough” individuals from a vast pool of applicants during lateral recruitment, which is no mean feat. It’s for this reason that cognitive tests come in handy. These tests are a recruiter’s essential resource for employee selection and come with measurable, demonstrable benefits.

This extensive guide will cover the intricacies of cognitive evaluations undertaken in hiring and introduce the most common cognitive assessments that recruiters and hiring managers use while recruiting candidates.


What is a cognitive assessment?

A cognitive assessment is a comprehensive evaluation of an individual’s intellectual, emotional, and psychological functioning. It includes a series of tests designed to gauge the cognitive responses of the individual regarding specific functions, such as attention to detail, memorization, processing speed, problem-solving skills, verbal abilities, etc. Cognitive assessments are a family of psychometric tests that make the whole candidate screening process a breeze by helping recruiters identify candidates who are more likely to excel at work and more competent at achieving their goals.

The cognitive evaluation process encompasses tests about conceptualization, critical thinking, visual and spatial skills, language proficiency, and learning agility, among other cognitive skills. Since this process employs highly predictive, quick-to-complete techniques, it enables the hiring managers to quickly filter out unsuitable applicants and interview candidates who stand the best chance of success in their prospective roles. Measuring the candidates’ cognitive capabilities can help recruiters identify candidates with untapped potential who may not have impressive resumes but possess all the desired traits to prosper in an organization. This testing is especially advantageous when interviewing individuals for entry-level positions, helping organizations hire intelligent and competent personnel at all levels of the organizational hierarchy.

The role of cognitive assessment tests is also pivotal in creating an organization’s learning and development strategy. Such tests address businesses’ loopholes while identifying training needs, high potential individuals, worthy successors, and fast learners. Moreover, psychological research consistently indicates that cognitive ability tests help predict hiring success across job types, levels, and industries with precision and ease.


Why should recruiters use cognitive tests for hiring?

Cognitive assessments bring candidates’ abilities to the fore that don’t show up on a CV or cover letter. These tests are crucial for candidate screening evaluations that help identify top talent and streamline and accelerate the recruitment procedure. Here are some of the prominent reasons why cognitive assessments are imperatively needed in recruiting:

They are effective predictors of job performance

Based on the works of I. Robertson, T. and M. Smith, Personnel Selection (2001), it’s safe to assume that cognitive tests are practical predictors of job-specific success. They considered some of the most commonly used approaches of personnel selection in their study: education level, graphology, personality tests, job knowledge tests, structured and unstructured interviews, references, and cognitive ability tests.




As depicted in the image above, cognitive ability tests coupled with behavioral assessments are shown on top with a 0.67 correlation coefficient to predict job success, which is greater than unstructured interviews, knowledge tests, personality tests, and years of job experience and education. A correlation coefficient of 0 signifies no correlation between variables, whereas a correlation coefficient of 1.0 signifies a strong positive correlation between two variables.

In this case, cognitive ability tests (r= 0.67) positively correlate with job performance compared to other factors. However, noteworthy here is that cognitive assessments can be used in unison with structured interviews, personality tests, behavioral tests, etc., for gaining holistic insights into a candidate’s job performance. Thus, cognitive evaluation is one of the most critical factors in the success of a hiring process.

They help identify exceptional learners

Cognitive tests can help organizations identify agile learners who can recalibrate their skillset against the future’s rapid, unforeseen technological advancements, primarily when unprecedented advances (such as artificial intelligence and automation) profoundly affect how we work. Individuals with higher cognitive capabilities organize, arrange and assimilate information more quickly, which is why they acquire new skills and grasp new concepts in a significantly lesser time, which later translates into higher organizational output.

They help recruit the best talent with minimal effort

Adopting cognitive testing as part of the recruitment process can help organizations secure the top talent in the market with minimal effort on the recruiter’s end. Why? Because high-quality cognitive assessment tests can be sourced from a leading service provider with the expertise and unmatched technical prowess in administering and evaluating the results against thousands of other candidates the world over.

They help in reducing bias in the hiring process

Cognitive tests provide actionable insights that help recruiters to include more objectivity in the hiring process. Unconscious biases often creep while recruiting candidates that can impact the effectiveness of the decision-making process. By using cognitive assessments, employers can hire applicants for their actual intelligence rather than seeing them through the lens of implicit bias. In addition, with data-driven and objective information about candidates at hand, organizations can build a diverse workforce of stronger recruits to build a more inclusive company culture.


What Does a Cognitive Test Measure?

Cognitive tests assess a candidate’s thinking abilities such as perception, reasoning, memory, verbal, and problem-solving ability. Such tests are designed to challenge applicants’ potential to solve problems when learning new job skills or tackling workplace issues. Commonly, cognitive assessments measure a person’s intelligence or general mental ability. Various mind-intensive questions that determine specific mental skills are based on verbal analogies, arithmetic calculations, spatial relations, comprehension, number series puzzles, and reading comprehension.

Most cognitive ability tests consider the number of correct answers and assign an overall score to those answers. This way, scores are a measure of the general mental ability of the person under consideration. When an individual score is attributed against each specific type of skill (verbal, reasoning, problem-solving), then the resulting scores measure specific cognitive abilities of that person.

People with high cognitive ranks are more likely to:

What Is the Purpose of a Cognitive Assessment?


The purpose of cognitive assessment is to determine an individual’s cognitive abilities on three main attributes: information processing, solution generation, and decision-making competencies. A high-quality cognitive assessment test will evaluate candidates’ aptitude for critical, numerical, and analytical reasoning, among other cognitive skills, to provide insights into their mental capabilities. Not to mention, the tests also intend to measure a person’s out-of-box creative approach and abstract reasoning competencies. Besides, cognitive ability tests even decide if a candidate is a problem solver and can effectively carry out rational, well-thought-out, and accurate decisions.


What is Included in a Cognitive Assessment?


A cognitive assessment focuses on the two most important competencies required to perform efficiently in any job. The test focuses on assessing a person’s ability to learn and retain information and apply it to solve problems and make intelligent decisions. These skills are evaluated through abstract reasoning and critical thinking-based tests. A cognitive test includes a set of intriguing questions to measure a candidate’s ability to be on the ball, disambiguate a puzzle, and unlock new concepts when presented with further information. The test also determines a person’s ability to question their assumptions, make fair evaluations, and identify relevant information when coming to conclusions.


What are the Cognitive Theories of Intelligence?

The roots of cognitive science date back to Charles Spearman, who proposed the g-factor theory. He asserted his firm belief that general intelligence forms the core of all mental abilities. The concept of cognitive skills stems from the idea that general intelligence is the bedrock of mental development. This example, in which we compare general intelligence with athleticism, will suffice.

A person might be an exceptionally gifted runner, yet this does not imply that he will likewise be a fantastic figure skater. Because this individual is an athlete, he will most likely perform better comparatively on other physically demanding tasks.

In the early 1990s, Charles Spearman used a numerical way to measure human intelligence. He was the one who helped develop a statistical technique known as factor analysis, which enables researchers to run through a variety of test items that can evaluate a candidate’s cognitive abilities. For example, a person who scores well on vocabulary questions might also perform better on reading comprehension questions.

So, he invented factor analysis, a mathematical approach to measure human intelligence, to explain the relationship between apparently varied cognitive abilities and understand the correlation between scores on different tests.

One of his students, Raymond Cattell, unconvinced by Spearman’s theory, developed the concept of fluid and crystallized intelligence.


Crystallized Intelligence

It refers to the mind’s ability to use prior knowledge and experience to make informed decisions. For example, solving a mathematical problem becomes easy with formula or applying grammatical rules to form correct sentences are all examples of crystallized intelligence.


Fluid Intelligence

It is the innate ability to solve unfamiliar problems through logical reasoning. This intelligence refers to the human capacity to think and act dynamically with precision. Fluid intelligence is independent of previous experience, practice, or education. For example, early men relied on their instincts and abilities to solve complex, life-threatening problems in the Stone Age.


Types of cognitive tests

Conducting a holistic cognitive evaluation won’t be an easy task if not for a cognitive assessment test. The cognitive test checks for the essential competencies required to perform any job efficiently. Such a test can assess a person’s mental construct in terms of their ability to think quickly, solve ambiguous problems, and devise new concepts when presented with novel information. So, here’s a rundown of the different types of cognitive tests that assess candidates on various cognitive aspects and are commonly used in the recruitment process:
