Pre employment math tests: How to evaluate your candidates’ skills using math assessments


Are you unsure of how to find employees with strong mathematical abilities? Are you planning to rely on resumes to gauge skills and make recruitment decisions?

There’s a better option – pre-employment math tests. They’re the fastest, most accurate method to assess your candidates and optimize your hiring process.

In this article, we review everything you need to know about pre-employment assessments, including the most important math skills assessments and how to use them to recruit the best applicants.

What is a pre-employment math test?

A pre-employment math test, also called a math aptitude test, is an evaluation used to screen job applicants for the math skills needed for a particular role. Pre-employment math tests are usually 10 to 30 minutes long and have multiple-choice questions. Although the questions are typically not too challenging, the time limit pushes candidates to think quickly, simulating the real-world demands of a job.

Pre-employment math aptitude tests are one of several cognitive ability tests performed in the screening stage to streamline the recruitment process.

These tests are part of a comprehensive pre-employment skills assessment, which evaluates candidates for hard and soft skills necessary for a position.

Why are math skills important in the workplace?

Employees with strong math skills are better prepared to make good business decisions to support your company’s growth. They can understand and analyze numerical data, make logical conclusions, assess results, compare outcomes, and evaluate risk. 

Math skills are also related to and support many other crucial skills, such as: 

  • Critical thinking and problem-solving skills

  • Reasoning and logic 

  • Precision and attention to detail

  • Analytical skills and the candidate’s ability to work with data

Which roles require a math aptitude test for employment?

According to research, 94% of all jobs require some math skills. You should consider including math skills tests in any pre-employment screening process.

A pre employment math assessment test can help you:

  • Identify hidden potential

  • Save time and money

  • Avoid hiring bias

Depending on the role you’re hiring for, you can use basic, intermediate, or advanced tests. In most cases, basic and intermediate tests are more than sufficient to find productive employees; however, strong math skills are necessary for fields such as: 

  • Engineering

  • Programming

  • Manufacturing

  • Science and research (especially STEM fields)

  • Finance and economics

  • Service and hospitality

  • Statistics

  • Sociology

  • Management

  • Analysis

  • Consultancy

  • Construction and design

How to evaluate candidates’ math skills during recruitment: 5 strategies

Employers use pre employment math assessments to get an accurate evaluation of candidates’ math skills. 

Let’s take a look at five different strategies you can use to evaluate candidates: 

1. Create and administer custom math tests

Creating a custom math skills assessment test for employment is the most resource-intensive way to evaluate your candidates. You need to:

  1. Prepare the tests

  2. Ensure all questions are correctly formulated 

  3. Administer them to applicants (either in person or online)

  4. Minimize the possibility of cheating

  5. Grade the tests manually and analyze the results

Preparing custom math tests is necessary for specific roles or fields (like those involving research), but there are usually faster and more efficient ways to test candidates’ math skills. 

Large organizations, like McKinsey and IBM, have the resources to control custom skills evaluations. However, this isn’t the best option for most smaller companies, given how time-consuming it is to create a custom math exam for employment. 

2. Look at education and experience

Although previous work experience, education, or academic achievements can indicate the strong math skills of your candidates, they are not the best ways to evaluate these skills.

Even if the candidate has this degree and spent the past five years working with data, how can you know the exact level of their knowledge or expertise?

The answer is: You can’t. Relying only on previous experience and education can lead to unconscious hiring biases.

In addition, you could hire someone who claims they have intermediate or advanced skills when they don’t. Without testing, you can’t find out before they start working for you.

This math skills gap can lead to significant challenges when they are required to apply these skills in practical scenarios, which affects productivity and project success. This is why you should use basic math tests for employment rather than assessing education or experience.

3. Use automated skills tests

Unlike custom tests that require significant time and resources to develop, automated skills tests provide a ready-to-use, standardized assessment tool to evaluate a person’s math abilities quickly. 

This method saves time and ensures consistency and objectivity in evaluation, minimizing the risk of similarity bias that affects 78% of hiring decisions.

As a result of using a basic math test for job preparedness, you are more likely to hire people who possess strong analytical skills, attention to detail, and problem-solving skills, helping them thrive in a math-heavy role.

For example, Orbit Technologies used our skills tests to hire highly skilled engineers. The combination of testing for technical skills like math, cognitive ability, and personality helped hire top candidates and reduce instant attrition rates by 50%.

4. Ask math interview questions

A good way to gain a deeper understanding of applicants’ knowledge is to use math skills interview questions. This approach is best when you use skills tests. 

You can tailor your math interview questions to the role you are hiring for and use structured interviewing to reduce bias and make candidate evaluation more objective.

Here are a few examples of questions you can use:

  • How do you convert fractions to percentages?

  • Can you describe a time when you used mathematical principles to solve a complex problem at work?

  • Can you explain how you can validate the accuracy of financial reports before presenting them to stakeholders?

5. Try a skills assessment platform

Whether you need a basic math test for job preparedness or something more advanced, skills-testing platforms like TestGorilla can help with ready-made tests.

You can use these talent assessments to measure skills like basic double-digit or triple-digit math for roles that require an understanding of elementary-level math. 

More complex assessments, like TestGorilla’s Intermediate Math test, evaluate applicants’ capacity to solve intermediate math problems involving percentages, fractions, decimals, ratios, and time calculations. 

Candidates who perform well on these tests can manipulate numbers and analyze numerical data to draw conclusions and solve problems. These skills can be valuable if a potential employee needs to create budgets, analyze metrics, assess risk, calculate salaries, interpret financial data, or perform other tasks that involve math calculations.

Advantages of using a math assessment platform

  • Objective: Candidates receive the same questions and are graded objectively based on their performance

  • Accurate: Tests are created by subject-matter experts and rigorously assessed by other specialists

  • Easy to administer: Regardless of how many candidates you want to screen, you can distribute skills tests with a single click

  • Automatically rated: The platform calculates test scores automatically, which makes it easy to evaluate and compare candidates’ skills
