Top 5 advantages of using aptitude tests in recruitment

Advantage of using pre-employment aptitude testHow it impacts the hiring process 
Cost effectiveAptitude tests for recruitment can help find the most eligible applicants for a job, reducing the need for additional recruitment efforts and saving on advertising and candidate screening costs.
UnbiasedPre-employment aptitude tests are given consistently to all applicants, guaranteeing that everyone is assessed using the same criteria. This serves to reduce differences in the recruitment procedure and reduces the possibility of bias.
Boost organizational diversityAptitude tests can be taken from anywhere allowing people from all over the world to be assessed, thus boosting potential for diversity across your organization.
Efficient recruitment toolAptitude assessments can be given swiftly and effectively, saving the HR department’s time spent interviewing and screening applicants.
Scientific validityAptitude assessments are designed based on research and psychometric principles to ensure that they accurately measure the abilities and skills that are relevant to the job.

Good to know: According to Sartori and Pasini, 2007, the objective of an aptitude test is to assess an applicant’s ability by scoring the speed and accuracy of their answers. Using these scores, the aptitude tests allow the employer to make a more informed hiring decision based on the candidate’s performance.

As we have explored the benefits of implementing aptitude tests in recruitment, it is important to acknowledge that like any assessment method, there are also potential challenges to consider. Now, let’s delve into the disadvantages of implementing aptitude tests, ensuring a comprehensive understanding of the subject and enabling you to make informed decisions for your recruitment process.

Top 5 disadvantages of using aptitude tests in recruitment

CONSHow it Impacts the Hiring Process 
Test anxiety
Test Anxiety is a frequent challenge that applicants face while taking an aptitude assessment. It can impact candidate performance, preventing them from displaying their true ability. It can be avoided by offering them practice tests and tools, as well as straightforward instructions, support, and encouragement throughout the testing process.
CheatingCheating on aptitude tests is possible, especially if they are given remotely, which can weaken the accuracy of the results. Opt for a provider with tools to minimise cheating and strict time conditions where cheating is less impactful.
Captures one aspect of a candidate’s performanceAptitude tests for recruitment do not assess a candidate’s psychological characteristics, work experience, motivation, or interpersonal skills, all of which can influence job success. An applicant may score well on an aptitude test but lack the required skills or expertise to perform well in the interview. It is important to use a range of assessments to ensure softer skills are captured to build an overall picture.
Time is required to design the aptitude testThe design of an aptitude test can take time and needs plenty of detail to get just right. Solve this by turning to an external provider as opted for by many organisations.
Not suitable for all rolesPre-employment aptitude assessments are unlikely to be suitable for all roles. It is key to consider the nature of your role and request consultation from a trusted advisor to build your perfect assessment process.

Having examined the pros and cons of implementing aptitude tests for job recruitment, it is crucial to explore how these tests are scored and understand the concept of percentiles. By delving into the scoring process we can gain a deeper understanding of how aptitude tests are evaluated and how they can effectively inform hiring decisions.

Let’s now explore the scoring methods and passing percentiles associated with aptitude tests in recruitment.

4. How are Aptitude Tests Scored and What are Passing Percentiles?

Since recruiters are in charge of administering the aptitude test, they can set a benchmark score or passing percentiles required for the candidates.

For example, a company may establish a passing percentile of 70%, indicating that individuals scoring at or above the 70% mark would be considered for future rounds.

You’re probably wondering what criteria you should use to determine a passing percentile.

Here are a few crucial factors that will help you to get more clarity:

  • Skills required for the job
    • If the job opening is for a financial analyst, a numerical reasoning test may be used to assess a candidate’s ability to analyze data and solve problems. The passing percentile for this test may be set at a level that reflects the level of analytical ability needed to be successful in the role.
    • Similarly, if the job requires strong verbal communication skills, a verbal reasoning test may be used to assess a candidate’s ability to understand and interpret written information.
  • Desired level of performance of candidates 
    • To ensure that only the highest-performing candidates are to be selected, you can set a passing percentile at 70% or 80%. This means that the candidates must score higher than the benchmark score to get selected. 
    • In some cases, a passing percentile may be set at 50%, depending on the number of job applications.

We recommend a lower cut-off at the 30th percentile. This helps ensure not too much weight is put on an assessment, as no method is 100% infallible. Rather, you safely sift and progress desired applicants through this method.

  • Precise evaluation: 
    • Evaluate the exact skills necessary for the position to determine the passing percentage for the aptitude test. It’s crucial to establish a passing percentile that represents the minimum performance required to succeed, considering factors like test complexity and applicant pool size. 
    • For example, to simply sift a larger pool into something more manageable, you may opt for a lower cut-off as recommended above to safely sift and progress applicants.

Now that we have covered how aptitude tests are scored and the importance of passing percentiles, let’s shift our focus to the ongoing validation and adaptation of these tests in the recruitment process. Exploring this continuous process will help us understand how aptitude tests remain reliable and relevant in assessing candidates over time.

5. How do Ongoing Test Validation and Adaptation Work in Recruitment for Aptitude Tests?

Ongoing test validation and adaptation are critical to keeping aptitude tests relevant and successful in the recruiting process. Here are some key details to consider:

  • Job Analysis: This involves assessing the knowledge, skills, abilities, and other qualities (KSAOs) necessary for effective work performance. Understanding the role’s unique needs allows you to determine if the existing aptitude tests you use effectively assess those KSAOs.
  • Test Review: Regularly review the content and format of aptitude tests to ensure they align with the job criteria. Assess the clarity and appropriateness of exam items, instructions, and scoring criteria. Additionally, evaluate if any updates or revisions are necessary due to industry changes, technological advancements, or evolving job duties.
  • Benchmarking: Determine benchmark scores or passing percentiles by studying the performance of current employees who have excelled in their positions. To detect trends or correlations, compare their aptitude test scores to their work performance. This data can be used to help future applicants determine suitable passing scores.
  • Legal Compliance: Ensure that the aptitude tests adhere to current legal criteria, such as equal employment opportunity (EEO) regulations and with the Disabilities Act. Review the tests regularly to detect and address any potential negative impact on protected groups. Make necessary changes to ensure the recruiting process is fair and inclusive.
  • Technology and Innovation: Stay up-to-date and Identify clever technologies and platforms that can improve aptitude test administration and scoring. Consider using adaptive testing approaches, which allow for a more exact evaluation of abilities by dynamically adjusting the difficulty level of the exam based on a candidate’s responses.
  • Continuous Improvement: Monitor and assess the success of the aptitude tests regularly, collect input from candidates and hiring managers, and remain current on industry best practices. Use this data to find areas for improvement and make modifications to increase the test’s efficacy.

While aptitude tests undergo ongoing validation and adaptation to ensure relevance, it’s crucial to question their effectiveness compared to traditional interviews. Aptitude tests for recruitment provide objectivity, while interviews are often said to be prone to biases.

Let’s explore the nature of aptitude tests and then weigh their predictive accuracy against traditional interviews.

6. Aptitude Tests vs. Traditional Interviews: Which Method Offers Better Predictive Accuracy?

Traditional interviews have long been the go-to method for evaluating job candidates, but research suggests they may not be the most accurate predictor of job performance. 

According to a Harvard Business Review survey, 63% of hiring managers believe traditional interviews fall short in assessing a candidate’s true capabilities. While interviews allow for open conversations and the evaluation of soft skills, they are prone to biases and first impressions, which can cloud judgment.

Aptitude tests, on the other hand, provide a more objective and unbiased evaluation of a candidate’s skills. These exams assess a candidate’s cognitive ability, problem-solving abilities, and other work-related traits, offering insightful information about how well they could function in their future roles.

A study conducted by revealed compelling evidence of the effectiveness of various cognitive ability tests, including aptitude tests, in predicting job performance with a validity coefficient exceeding 51% (Hurtz & Donovan, 2000).

Both aptitude tests and traditional methods of interviewing can be used by a wide range of companies, and the choice between them often depends on various factors, including:

  1. The company’s industry
  2. Size
  3. Resources
  4. Hiring goals 

Aptitude tests are highly valued in

  • Large corporations with high-volume hiring needs
  • Technical and STEM industries
  • Consulting and professional services firms

Traditional interviews are preferred in:

  • Small and medium-sized enterprises (SMEs)
  • Creative and artistic industries
  • Relationship-driven industries (e.g., sales, customer service)

The approaches a firm chooses to use to evaluate job candidates, traditional interviews or aptitude tests, depends on the requirements and preferences of that particular organization. A hybrid strategy that combines the two approaches can result in a more thorough and accurate review, which will eventually improve recruiting decisions.

Now that we have explored the aptitude tests versus traditional interviews in assessing candidate performance, we will take a look at examples of aptitude tests used in recruitment.
