Recruiters in today’s job market have a tough job. It’s not just about spotting candidates with the right skills—it’s about finding the ones who’ll excel in the company’s culture and help drive its success. That’s a tall order!

This is where selection tests come in. These assessments are game-changing tools that help recruiters dig deeper, making it easier to identify the best fit from a sea of applicants.

In this guide, we’ll take you through everything you need to know about selection tests. You’ll explore the different types, learn best practices for using them, and see how they can help you make smarter, more confident hiring decisions.

Types of Selection Tests

Selection tests offer a standardised and objective way to assess candidates’ abilities, personality traits, and suitability for specific roles. They provide valuable data that complements resumes and interviews, painting a more holistic picture of each applicant. Let’s delve into the most common types of selection tests:

Cognitive Ability Tests

• Purpose: Cognitive ability tests, often referred to as aptitude tests, measure an individual’s mental capabilities. They assess a range of cognitive skills, including:
• Reasoning: The ability to think logically, solve problems, and identify patterns. This can involve deductive reasoning (drawing conclusions from given information), inductive reasoning (identifying patterns and making generalisations), and spatial reasoning (visualising and manipulating objects in mind).
• Memory: The ability to recall information, both short-term and long-term. This can include remembering lists of words or numbers, recognizing patterns, and recalling details from passages of text.
• Verbal Comprehension: The ability to understand and interpret written information. This involves reading comprehension, vocabulary, and the ability to analyse and draw conclusions from written material.
• Numerical Aptitude: The ability to work with numbers, perform basic calculations, and interpret numerical data. This can include arithmetic, data analysis, and numerical problem-solving.
• Perceptual Speed: The ability to quickly and accurately compare and identify visual information, such as symbols, numbers, and patterns.

Types of Cognitive Ability Tests:

• Wonderlic Personnel Test: This widely used test measures general cognitive ability through a series of questions covering vocabulary, logic, maths, and spatial reasoning. It’s known for its short duration (12 minutes) and its ability to predict job performance across a range of occupations.
• SHL General Ability Test: This assessment evaluates verbal, numerical, and inductive reasoning skills. It’s often used for graduate recruitment and managerial positions.
• Raven’s Progressive Matrices: This non-verbal test assesses abstract reasoning and problem-solving abilities. It’s particularly useful for roles requiring critical thinking and analytical skills.

Advantages of Cognitive Ability Tests:

• Strong Predictive Validity: Research consistently shows that cognitive ability tests are one of the most reliable predictors of job performance across various roles and industries. A meta-analysis by Schmidt and Hunter (2004) found a correlation of .51 between general mental ability and job performance, indicating that cognitive ability is a significant factor in workplace success.
• Objective Measurement: Cognitive ability tests provide standardised and objective measures of mental capabilities, reducing the influence of subjective biases in the selection process.
• Cost-Effective: These tests are generally cost-effective to administer, especially online versions, making them an efficient way to screen a large number of candidates.

Considerations for Cognitive Ability Tests:

• Potential for Adverse Impact: It’s crucial to ensure that cognitive ability tests are carefully selected and validated to minimise any potential for adverse impact on certain demographic groups. Regularly review test results and consider using multiple assessment methods to mitigate this risk.
• Not a Complete Picture: While cognitive ability tests are excellent predictors of job performance, they don’t assess other important qualities such as personality, work ethic, and emotional intelligence. It’s essential to use them in conjunction with other assessment methods to gain a comprehensive view of candidates.

Personality Tests

Purpose: Personality tests assess an individual’s behavioural traits, interpersonal skills, and personality preferences. They provide insights into how candidates are likely to interact with colleagues, handle stress, and approach their work.

Popular Personality Test Models:

• The Big Five: This model, also known as the Five-Factor Model, is a widely recognized framework for understanding personality. It assesses individuals based on five broad dimensions:
• Openness to Experience: Imaginative, curious, and open to new ideas versus conventional and practical.
• Conscientiousness: Organized, responsible, and dependable versus careless and impulsive.
• Extraversion: Outgoing, sociable, and energetic versus solitary and reserved.
• Agreeableness: Friendly, compassionate, and cooperative versus challenging and detached.
• Neuroticism: Prone to anxiety, worry, and emotional instability versus calm and emotionally stable.
• Myers-Briggs Type Indicator (MBTI): This popular assessment categories individuals into 16 personality types based on their preferences in four dichotomies:
• Extraversion (E) or Introversion (I): How individuals gain energy (from external interactions or internal reflection).
• Sensing (S) or Intuition (N): How individuals perceive information (through their senses or through patterns and possibilities).
• Thinking (T) or Feeling (F): How individuals make decisions (based on logic or values).
• Judging (J) or Perceiving (P): How individuals approach the outside world (in a structured or flexible manner).
• Hogan Personality Inventory (HPI): This assessment focuses on normal personality characteristics and is often used to predict workplace performance and derailment risks. It measures aspects like adjustment, ambition, sociability, interpersonal sensitivity, prudence, inquisitiveness, and learning approach.
• XXWX Personality: XXWX personality is made up of the four traits: introverted, intuitive, thinking, and perceiving.

Advantages of Personality Tests:

• Cultural Fit Assessment: Personality tests help identify candidates whose personality traits align with the company’s culture and values. This can lead to increased job satisfaction, better teamwork, and lower turnover rates.
• Team Dynamics: By understanding candidates’ personality preferences, recruiters can build teams with complementary strengths and minimise potential conflicts.
• Leadership Potential: Some personality tests can identify traits associated with effective leadership, helping organisations identify and develop future leaders.

Considerations for Personality Tests:

• Self-Reporting Bias: Personality tests rely on candidates’ self-reported responses, which can be subject to social desirability bias (trying to present oneself in a positive light). It’s important to use well-validated tests and consider incorporating other assessment methods to gain a more complete understanding of candidates.
• Interpretation Expertise: Proper interpretation of personality test results requires expertise. Recruiters should be trained to understand the nuances of different personality traits and how they relate to job requirements and company culture.

Skill-Based Tests

Purpose: Skill-based tests, also known as job knowledge tests or proficiency tests, directly assess candidates’ abilities to perform specific tasks required for the job. These tests measure practical skills and knowledge relevant to the role.

Types of Skill-Based Tests:

• Technical Tests: These assess technical skills and knowledge in areas such as coding, software development, engineering, and data analysis. They often involve coding simulations, problem-solving exercises, or knowledge-based questions.
• Software Proficiency Tests: These evaluate candidates’ skills in using specific software applications, such as Microsoft Office Suite, Adobe Creative Suite, or industry-specific software.
• Job Simulations: These simulate real-life work scenarios to assess how candidates would handle specific tasks and challenges. This can include role-playing exercises, in-basket exercises (responding to a series of emails and tasks), or case studies.
• Work Sample Tests: These require candidates to complete actual tasks that are representative of the job, such as writing a press release, designing a website mockup, or analysing a data set.

Advantages of Skill-Based Tests:

• Directly Relevant: Skill-based tests provide a direct measure of candidates’ abilities to perform job-related tasks, making them highly relevant to the selection process.
• Objective Assessment: These tests offer a standardised and objective way to evaluate skills, reducing subjectivity and potential bias in the hiring process.
• Performance Prediction: Skill-based tests can be strong predictors of future job performance, as they directly assess the skills and knowledge necessary for success in the role.

Considerations for Skill-Based Tests:

• May Be Too Narrow: Focusing solely on specific skills may overlook other important qualities, such as problem-solving abilities, adaptability, and learning potential. It’s essential to use skill-based tests in conjunction with other assessment methods to gain a broader perspective.
• Development and Validation: Developing and validating effective skill-based tests can be time-consuming and resource-intensive. It’s important to ensure that tests accurately reflect the essential skills required for the job and are free from bias.

Once you’ve determined the appropriate types of tests, you need to decide on the best method of administration.

Methods of Selection Test Administration

The way you administer selection tests can significantly impact their effectiveness and the candidate experience. Consider these different methods:

In-Person vs. Online Testing

In-Person Testing:

• Reduced Confidence in Results: The lack of proctoring can lead to concerns about the reliability of the results and whether candidates completed the test independently.

Computer Adaptive Testing (CAT)

How it Works: Computer adaptive testing dynamically adjusts the difficulty of the test questions based on the candidate’s responses. If a candidate answers a question correctly, the next question will be more challenging. If they answer incorrectly, the next question will be easier. This process continues throughout the test, tailoring the difficulty level to each individual.  

Advantages of CAT:

• Increased Accuracy: CAT provides more precise measurements of ability, as it focuses on questions that are most relevant to the candidate’s skill level.
• Reduced Test Time: By adapting to the candidate’s ability, CAT can significantly reduce the overall testing time without compromising the accuracy of the results.
• Improved Candidate Experience: CAT can provide a more engaging and personalised testing experience, as candidates are presented with questions that match their abilities.

Considerations for CAT:

• Technical Complexity: Implementing CAT requires sophisticated algorithms and software, which can be more complex than traditional testing methods.
• Item Bank Requirements: CAT requires a large and diverse pool of test questions to ensure that the test can adapt to a wide range of abilities.
